By Rob Quinn,  Newser Staff
Posted Mar 2, 2023 10:15 AM CST

The Little Mermaid statue in Copenhagen, one of Denmark's most famous landmarks, has been vandalized yet again, this time with the Russian flag. Authorities said Thursday that the white, blue, and red stripes of the Russian flag were painted on the stone the statue sits on, Reuters reports. Police said the vandalism was discovered early Thursday. "We are of course launching an investigation to find out who did it and when and how it happened," a police spokesman said, per Jyllands-Posten.

Denmark, like other European nations, has strongly criticized Russia's war against Ukraine. The small statue, a tribute to the Hans Christian Andersen fairy tale, sits off a waterfront promenade in the Danish capital. It has been vandalized many times since it was installed 110 years ago, AFP reports. It has been decapitated twice and was knocked off its base with explosives in 2003. In 2017, it was doused in red paint in a protest against whale hunting. In 2020, during worldwide protests after the death of George Floyd, the words "racist fish" were painted on the base, though Andersen scholars said they weren't aware of any racist elements in the fairy tale.

The statue, which sits next to a relatively secluded waterfront walkway, has been vandalized several times over the years, including two burglaries of its head in 1964 and 1998, and a severed arm in 1984. In 2003, the statue was blown loose with explosives and fell into the bay.
It has also been graffitied and painted several times, most recently in 2020 with the words “racist fish. ”

Content: Fairytale-like European city is 'spellbinding' and has 'something for everyone'

A beautiful European town is a destination full to the brim of exciting and interesting things to do.

By Paul Tregunna, Travel and Lifestyle Reporter

Nyhavn has become synonymous with Copenhagen (Image: Getty)

The Nordic countries are perhaps the closest opportunity travellers have to transport themselves into their very own fairy tales.

With beautiful cities and charming locals, they are some of the finest countries in the world to visit.

None more so than Denmark, an incredibly friendly country that connects mainland Europe to Scandinavia.

Its capital city, Copenhagen, is one of the continent's most well-known places, yet it isn’t as popular a city break destination as it perhaps should be.

With its colourful houses and lively atmosphere, the iconic area of Nyhavn has become synonymous with Copenhagen.

The colourful houses of Nyhavn are the perfect backdrop to relax and grab a drink (Image: Getty)

A perfect place to kick back and grab a drink by the water, Nyhavn was originally a commercial port welcoming ships from all over the world.

Once home to the legendary writer Hans Christian Andersen, the neighbourhood wouldn't look out of place in a picture book itself.

There are a number of boat trips operating from Nyhavn, offering visitors a chance to explore the sights of Copenhagen by water. It is a great opportunity to get your bearings and spot any attractions you’d like to see up close, whilst providing interesting commentary on the history of this fantastic city.

You can buy tickets for one of the boat trips on the day from Nyhavn, but they can also be purchased online in advance. The prices vary depending on which provider you choose to travel, and tickets should range from around £16-£20 for an hour-long journey.

Hans Christian Andersen’s presence is still felt throughout the city. You have the opportunity to get up close and personal with the Danish Author at the Hans Christian Andersen Experience - a charming and interactive museum detailing his life and the fairy tales he penned.

The Hans Christian Andersen Experience is a part of Ripley’s Believe it or Not, an entertaining exhibition on the world’s weirdest and wackiest true stories. You can purchase a combo ticket for both from 206 KR (£23.74) for an adult, and 139 KR (£16.02) for a child aged 4-11.

One of Hans Christian Andersen’s most famous stories is The Little Mermaid, which was written in 1837 and has subsequently been adapted into a number of films. In the Langelinie area of Copenhagen there is a bronze statue depicting the titular mermaid, unveiled in 1913, which is well worth taking the time to see.

Another of Copenhagen’s most iconic attractions is the spectacular Tivoli Gardens, one of the oldest amusement parks in the world.

With something for everyone, Tivoli has roller coasters, rides, shows and a feel-good atmosphere. If Disney is the ‘happiest place on Earth’, Tivoli mustn't be far behind.

The sheer scale of Tivoli is mind-blowing, and you can easily spend a full day there and not cover everything. There are a number of ticketing options which can be viewed on the Tivoli website, but bear in mind Tivoli Gardens reopens on March 22.

Connected to Tivoli is a superstore specialising in one of Denmark’s most famous exports - LEGO.

The LEGO Store Tivoli Gardens is a must visit for fans of the iconic building blocks, as the highlight of the shop is a station where you can design and make yourself out of LEGO, providing a truly unique memento.

The Church of our Saviour's spectacular spiralling spire offers fantastic views over Copenhagen (Image: Getty)

Standing tall over the city is the spellbinding spire of Our Saviour’s Church, which visitors have the opportunity to climb.

After ascending 400 steps, with the last 150 externally spiralling around the tower, you will be blessed with one of the best views of Copenhagen - some 262 feet in the air.

Entrance to the tower is free, but it is advisable to book online in advance to secure a timeslot. If you aren’t a fan of heights, it’s best you give the climb a miss.

Residents of Copenhagen dug up the street Puscher Street in the central commune of Christiania, where for many years there was a drug trade, reports TV2 Kosmopol.

Work began on the morning of April 6, around 10: 00 local time (11: 00 MSK).
The crowd took shovels and began to lift the stones with which the street was paved.
In the photo, which showed the channel, it is clear that the activists dug up all the stones and stacked them in a pile to a dead end.
Before that, the street was completely cleared of stalls.
Copenhagen Mayor Sophie Hastorp Andersen and Justice Minister Peter Hummelgor joined the rally and a large number of police officers were present.

In an interview with TV2, Hastorp Andersen expressed confidence that this time the hashish trade will be stopped completely.
“We looked each other in the eye and everyone agreed that enough was enough.
We worked very closely together and found solutions.
This time the difference is that we stand together, ” she said.
The Danish government has confirmed that it regards the closure as final.
The deputy inspector of the local police, Simon Hansen, in charge of monitoring the operational situation in the commune, in turn, said that the police will patrol the area in the next few days.
In January, Denmark ’ s justice minister vowed to shut down Pusher Street after Christiania ’ s residents appealed to the government.
He did not give an exact date, but assured that this will happen within six months.
Authorities in other districts did not rule out that drug traffickers would reorient themselves to them after the closure of Pusher Street.
Such concerns were expressed, in particular, by the head of the urban district of Nørrebro in the north-western part of Copenhagen, Mogens Petersen, writes Berlingske.

COPENHAGEN (AFP) - The iconic Little Mermaid statue in the Danish capital Copenhagen was vandalized on Wednesday night as unidentified people painted the Russian flag on its base.
Announcement
An AFP correspondent reported that the Russian flag was painted under unknown circumstances on the stone above which a statue of the Little Mermaid, inspired by the heroine of one of the stories of the writer Hans Christian Andersen, was installed.
Danish police said they were launching an investigation into the incident, without giving any indication of the source of the move, which shows clear support for Russia amid the ongoing war in Ukraine.
A Copenhagen police spokesman told AFP: "We are investigating the area in order to find any evidence."
A small number of tourists in the area took pictures of the statue in the port of Copenhagen, which was vandalized on Thursday morning.
The Little Mermaid statue on a largely unfrequented promenade has been targeted several times since it was installed in 1913.
In 1964, the head of the nymph was stolen for the first time without being recovered.
In 1998, a group of vandals cut off the head of the statue again, but it was later restored.
This monument was exposed to the explosion in 2003.
The statue, created by Danish sculptor Edvard Eriksen, has also been targeted several times with graffiti or graffiti, most recently in 2020 with the inscription “racist fish ”.

Utilizing biogeochemical and genetic tools to understand and support clam populations in a changing ocean

Marine bivalves are at risk due to anthropogenic climate change. This poses a threat to commercial aquaculture, and the communities that depend on bivalves for food security. Ocean acidification, the lowering of seawater pH, is of particular concern for marine calcifiers, including bivalves. Ocean acidification occurs as carbon dioxide enters the atmosphere at a rate faster than natural geologic processes can buffer. It is energetically costly for marine calcifiers like clams, mussels, and oysters, to mineralize under acidic conditions, and low pH leads to the dissolution of calcium carbonate shells and skeletons. This problem warrants research on acidification adaptation strategies that will keep coastal populations healthy. Adding calcium carbonate shell hash to coastal sediments may mitigate negative effects of acidification on infaunal shellfish by altering the chemistry of pore fluids, thus providing a potential mitigation strategy for local populations, including species like the Pacific littleneck clam (Leukoma staminea).

Here, I present the first in-depth description of the shell mineralogy, microstructure, body size variability, and geochemical properties of modern L. staminea, a common eastern Pacific, shallow, infaunal bivalve. Additionally, I document the impact of ocean acidification on the shell growth and gene expression of L. staminea, and test whether adding shell hash to its infaunal environement can promote growth under acidified conditions. Juvenile clams were raised in four experimental conditions for 90 days: control seawater, acidified seawater, control seawater with shell hash, and acidified seawater with shell hash. Clam shell weight, soft tissue weight, and new shell growth were measured. The presence of shell hash increased the pH, alkalinity and aragonite saturation state of pore fluids across all treatments, and increased shell growth on average, although growth metrics were variable across and within treatments. Lastly, RNA-sequencing revealed the impacts of experimental acidification on juvenile clam gene expression. Clams grown in the presence of shell hash had gene expression profiles more similar to those grown in control (non-acidified) conditions. In all, this research suggests that adding shell hash to coastal sediments alters the chemistry of pore fluids and buffers against acidic conditions that deleteriously affects clam mineralization.

In addition to causing climate warming, global emissions of large amounts of carbon dioxide will also cause sea water to become acidic, and marine life may be affected.
The study found that volcanic infiltration of high CO2 partial pressure, that is, high concentrations of CO2 dissolved in water, changes in the genetic transcription of fish, predict the response of wild fish to the continuous acidification of the marine environment.
The results show that some fish with faster rates of evolution may be more flexible in coping with ocean acidification, maintaining population size and diversity. One species of fish may be able to acidify the marine environment with its rapid evolution of gene molecular transcription regulation, but the population size and diversity of fish with slower rates of evolution are difficult to maintain in acidified environments.
As carbon dioxide emissions from human activities increase year by year, and the CO2 absorbed by the ocean continues to rise, causing the pH of seawater to decline and become acidic, scientists expect “ocean acidification ” on the surface of the world ’ s oceans, which may affect the physiology, growth and survival of some fish, and change some key behaviors that affect survival chances.
A team led by Celia SCHUNTER from the Faculty of Biosciences of the University of Hong Kong and the Swire Institute of Marine Science, along with foreign researchers, travelled to Papua New Guinea, the Pacific island nation, to extract the brains of six species of coral fish, including five species of finch and one species of celestial bream, from a carbon dioxide spill at the bottom of a volcano and about 500 m nearby coral reef. The organization conducts gene transcription group sequencing to understand the changes in fish gene transcription in the ocean acidification environment.
The results show that high CO2 partial pressure can cause transcription changes in genes related to circadian clock and immune function in several species, demonstrating that fish function is important in coping with acidifying environments, and that the core genes of circadian rhythms determine the 24-hour cycle of most species.
Immune-related regulation has been found in many species of fish in acidified environments, so regulation of the immune response may also be an important response to acidification, especially in nocturnal fish, which exhibit a greater proportion of immune regulation and are modulated in the opposite direction to diurnal fish.
In contrast to the fish body ’ s ability to regulate the pH value of the cells, the researchers found that the brain of the spinosus is used to maintain a large number of changes in potassium, sodium, chlorine and calcium ions that transmit signals in the carbon dioxide ooze. Corresponding changes are needed to cope with the acidification environment, but differences in the expression of related genes disappear when stress is reduced, and genes return to normal levels of expression.
Further research by the team found that this finch has evolved significantly faster than other fish over the past 15 million years, potentially giving it greater potential to adapt to environmental changes.
It is speculated that this species may have evolved molecular mechanisms to cope with future ocean acidification.

« Research » conducted a study on the impact of « acidification » on shrimp
The Kuwait Institute for Scientific Research (KISR), in cooperation with the Kuwait Foundation for the Advancement of Sciences (KFAS) and the International Atomic Energy Agency (IAEA), completed a study project to investigate the impact of ocean acidification and ocean surface warming on the growth and abundance of local shrimp.
In turn, the head of the project, researcher Lamia Muslim at the Center for Environmental and Life Sciences Research at the Institute, said that there are many animals that contain in their skeleton or shell calcium carbonate, and changes in the pH of water can negatively affect these organisms, especially in the early stages of their life. The sea and some phytoplankton species, but that does not mean that this is a positive thing because the increased growth of these organisms can disrupt the food chain, biodiversity and ecosystem mechanisms and construction.
She added that the presence of large amounts of carbon dioxide in the atmosphere leads to the occurrence of global warming and the rise of the surface of the oceans by between one and three degrees Celsius, and the rise of the water level to an amount ranging from 0.18 to 0.79 meters, which in turn leads to acidification and warming of the surface of the oceans, and therefore to change the chemistry of the ocean and threaten marine ecosystems.
She pointed out that the shrimp mothers were collected from Kuwaiti territorial waters during the breeding season to obtain eggs and shrimp larvae in sufficient numbers to conduct experiments on all stages of shrimp age, as the study experiments were conducted in the laboratories of the Institute in a controlled system simulating the expected climate changes in the future.
The results of the study confirmed that the warming of the surface of the oceans could have a greater impact than ocean acidification on the early life stages of shrimp larvae, as shrimp larvae exposed to high temperatures showed accelerated growth rates to reach the sizes of older shrimp, but with lower survival rates, it is very likely that lower survival and growth rates under future climate scenarios may lead to the emergence of smaller shrimp larvae. These larvae will undergo multiple molting processes over their life cycle making them vulnerable; furthermore, the study results suggest additional effects of combined exposure to ocean surface warming and acidification on egg-hatching success, survival, and shrimp larval development.
Al-Musallam said: “The study is fully consistent across the entire life cycle of the M Nair shrimp, where high mortality of larvae at low pH and high water temperature indicates a possible collapse of this species of crustacean under conditions of increased ocean acidification and future warming of the ocean surface, which also leads to a significant reduction in shrimp stocks in the Arabian Gulf due to overfishing or reduced larval growth due to climate change. ”
For his part, dr.
Dr. Saifuddin Iqbaluddin, from the Center for Environmental and Life Sciences Research, said experts regularly measure water temperature and pH levels and look at how marine life might respond to these changes in the coming decades.

University of Adelaide: Octopus eyes blurred due to heat stress
Australian biologists from the University of Adelaide found that the heating of the water of the oceans due to climate change negatively affects the vision of octopuses.
The study was published on the official website of the scientific institution.
"We found several proteins important for vision that are affected by heat stress.
One of them is a structural protein, which is found in large quantities in the lenses of the eyes of animals and retains the transparency and optical clarity of the lens, and the other is responsible for the regeneration of visual pigments in the photoreceptors of the eyes.
"Levels of both of these proteins have been significantly reduced in the face of projected ocean warming, suggesting that octopus vision is likely to deteriorate even further," explained Dr Kiaz Hua.
The eyes remain the main sense organ for octopuses.
In these animals, 70% of the brain is responsible for vision, which is 20% than in humans.
Scientists have also found that higher water temperatures accelerate the metabolism of octopuses, make them smaller and change the distribution area of some species of these mollusks.
In addition, the warm ocean has a negative effect on the reproduction of the octopus, reducing the number of eggs that spawn.
In some cases, entire broods remained unhatched, the researchers noted.
Earlier it became known that octopuses are the oldest animals with sex chromosomes.

How climate change is changing the brain and behavior of animals
Due to global warming caused by human activities, the habitat on Earth is changing more and more.
This leads to an increase in temperature, rapid changes in rainfall and seasons, and ocean acidification.
How do animals deal with this?
Population Connection
In the response of animals to climate change, their nervous system plays a key role.
Due to its basic functions (sense detection, mental processing of information, behavior control), animals are oriented in the environment, can survive and reproduce.
Because of temperature changes, the energy balance of ecosystems is changing.
It is likely that this will also affect their basic senses, from sight and taste to smell and touch.
Mammals partially perceive temperature with the help of special receptor proteins in their nervous system.
These proteins respond to heat and cold, helping to distinguish between moderate and extreme temperatures.
Due to these proteins, animals can also look for a suitable habitat.
GETTY
Climate change disrupts the environmental signals that animals rely on when choosing their habitat, finding food, and partners.
Temperature shifts, for example, change where and when mosquitoes look for hosts, how they transmit diseases.
In addition, seasonal changes in daylight can lead to disconnection between daylight hours and flowering and fruiting of plants, changes in hibernation and migration of animals, when daylight hours no longer predict the availability of resources.
Due to the increase in temperature, the development and functioning of the brain of animals can be
This could also potentially affect their ability to adapt effectively to new habitats.
Scientists have found out how extreme temperatures can change individual neurons at the genetic and structural levels, the structure of the brain as a whole.
For example, in the marine environment, ocean acidification can affect the tracking of odors in reef fish and sharks.
Because of climate change, animals can change their habitat.
These behavioral shifts will change the structure of ecosystems around the world with complex and unpredictable consequences.
It is known that the brain of animals is very flexible and can significantly change even in adults.
However, studies have revealed a strong influence of the environment on the evolution of the brain.
Most likely, the new climatic regimes will eventually form nervous systems, causing them to develop.

Ocean acidification is a pressing issue that affects marine life, including cephalopods, by increasing the acidity of the water due to rising carbon dioxide emissions.

Cephalopods, such as octopuses, are impacted by ocean warming, which affects their vision due to heat stress, causing blurred vision and reduced protein production for vision.

Ocean acidification also affects the relatives of cephalopods, such as pteropods, which are crucial for the ocean environment and are sensitive to acidity, with winter sea butterflies being more vulnerable to acidification.

Pteropods, like sea butterflies, have different life cycles, and some species, such as L. rangii, have a survival advantage over others, like L. retroversa, in acidified waters.

Ocean acidification threatens the larvae of sea butterflies and can cause prolonged exposure to acidification to be harmful.

Cephalopods, including octopuses, are also affected by warmer waters, which can accelerate their metabolism, making them smaller, and changing their distribution areas.

Warmer oceans can also negatively affect octopus reproduction, reducing egg spawning numbers and causing entire broods to remain unhatched.

While there is limited information on the direct effects of ocean acidification on cephalopod physiology and behavior, it is known that ocean acidification can impact animals with calcium carbonate skeletons, such as abalone and shrimp.

Abalone growth performance is affected by ocean acidification, with low CO2 buffering capacity impairing growth, and low calcium carbonate saturation state eroding shells.

Shrimp larvae are vulnerable to ocean acidification and warming, with lower survival rates and accelerated growth at high temperatures, and combined warming and acidification affecting egg-hatching success.

Ocean acidification and warming can have devastating effects on marine life, including cephalopods, and can lead to changes in ecosystem structure and function.

Seagrass meadows can help mitigate the effects of ocean acidification by increasing pH levels and reducing sea urchin larvae malformations.

Seagrass photosynthesis can alter seawater chemistry, aiding larval development at low pH and helping to prevent climate-driven biodiversity loss.

Overall, ocean acidification has far-reaching impacts on marine life beyond coral reefs, and it is essential to continue studying its effects to develop effective conservation strategies.

Ocean acidification is a pressing issue that affects marine life, including cephalopods, by increasing the acidity of the water due to rising carbon dioxide emissions.

The study was published on the official website of the scientific institution.
"We found several proteins important for vision that are affected by heat stress.
One of them is a structural protein, which is found in large quantities in the lenses of the eyes of animals and retains the transparency and optical clarity of the lens, and the other is responsible for the regeneration of visual pigments in the photoreceptors of the eyes.
"Levels of both of these proteins have been significantly reduced in the face of projected ocean warming, suggesting that octopus vision is likely to deteriorate even further," explained Dr Kiaz Hua.
The eyes remain the main sense organ for octopuses.
In these animals, 70% of the brain is responsible for vision, which is 20% than in humans.
Scientists have also found that higher water temperatures accelerate the metabolism of octopuses, make them smaller and change the distribution area of some species of these mollusks.
In addition, the warm ocean has a negative effect on the reproduction of the octopus, reducing the number of eggs that spawn.
In some cases, entire broods remained unhatched, the researchers noted.
Earlier it became known that octopuses are the oldest animals with sex chromosomes.

Ocean acidification also affects the relatives of cephalopods, such as pteropods, which are crucial for the ocean environment and are sensitive to acidity, with winter sea butterflies being more vulnerable to acidification.

Title:

Content: Newswise — When carbon dioxide (CO2) enters the oceans, it can make the water more acidic, which is called ocean acidification. This can make it harder for some ocean creatures, like pteropods, to build and keep their shells. Pteropods are important for the ocean environment.

Pteropods are small sea creatures, including shelled sea butterflies. Not much is known about them because of their size, and they don't survive well in captivity. A team of marine scientists studied the life cycles, abundance, and seasonal changes of shelled sea butterflies in the north-east Scotia Sea, where climate change is happening quickly.

Dr Clara Manno, a researcher at the British Antarctic Survey and the corresponding author of the study published in Frontiers in Marine Science, said that the decrease in pteropod populations in the Antarctic Ocean could have significant consequences for the food web and carbon cycle. She also said that understanding the life cycle of this important organism could help to predict the impact of ocean acidification on the Antarctic ecosystem.

Population stability essential for species survival

To study the life cycle, abundance, and seasonal variability of shelled sea butterflies in the north-east Scotia Sea, a team of marine scientists collected sea butterflies in a sediment trap, a sampling device that was anchored at a depth of 400 meters. Since observing the entire life cycle of sea butterflies in a laboratory setting is impossible, the researchers had to gather information about their spawning, growth rate, and population structure. They were able to reconstruct the sea butterflies' life cycle for a year using the samples from the sediment trap.

The scientists found that the two most commonly collected species, Limacina rangii and Limacina retroversa, have different life cycles and therefore have different levels of vulnerability to changes in the ocean. During the winter months, L. rangii, which is a polar species, can be found as both adults and juveniles, while L. retroversa, a subpolar species, is only found as adults during the winter.

Sea butterflies that exist during the coldest season are more vulnerable to increased levels of ocean acidification. This is because ocean water is more acidic during this season than during other times of the year due to cooler temperatures that increase CO2 dissolution in the ocean. The researchers explained that the life stages of sea butterflies during this time are more exposed and vulnerable to the effects of ocean acidification.

L. rangii has a survival advantage over L. retroversa because both adults and juveniles coexist during winter, which reduces the risk of population instability if one cohort is vulnerable. In contrast, if one cohort is removed from L. retroversa, the entire population could be at risk.

Prolonged exposure is a survival challenge

The researchers pointed out that although the two species are affected differently, both are likely to suffer harm if they are exposed to unfavorable conditions for prolonged periods.

The scientists cautioned that the intensifying and prolonged events of ocean acidification overlap with the spring spawning period, posing a threat to the most vulnerable life stage, the larvae. This could endanger the future populations of sea butterflies.

The research team plans to further study the sea butterflies in the Scotia Sea to see how they would be affected by the increase in the intensity and duration of ocean acidification events. They will study multiyear sediment trap samples to identify potential changes in the life cycle that may occur due to environmental changes. Dr Jessie Gardner of the British Antarctic Survey, lead author of the study, said this will be the next step in their research.

Cephalopods, including octopuses, are also affected by warmer waters, which can accelerate their metabolism, making them smaller, and changing their distribution areas.

Warmer oceans can also negatively affect octopus reproduction, reducing egg spawning numbers and causing entire broods to remain unhatched.

While there is limited information on the direct effects of ocean acidification on cephalopod physiology and behavior, it is known that ocean acidification can impact animals with calcium carbonate skeletons, such as abalone and shrimp.

A 45-day trial was conducted to study the effect of seawater total alkalinity (TA) level up- and downregulation on the growth performance and calcification of Haliotis discus hannai Ino, while seawater pH was maintained at pHNBS = 8.1. Although seawater was not acidified, the results showed that TA downregulation caused a significant reduction (P < 0.05) in the somatic tissue growth of juvenile abalone, while TA upregulation significantly increased growth performance (P < 0.05). Similar to the impacts of pH reduction, TA downregulation also induces a decline in CO2 buffering capacity, which may be the reason why somatic tissue growth was reduced, as lowered CO2 buffering capacity was reported to shift the acid-base balancing of abalone. Parts of the periostracum layer weremissing and exposed the inner shell layers of the individuals from the TA-downregulated group. Scanning electron microscopy (SEM) results showed calcium carbonate densely deposited onto the inner shell in the control and TA-upregulated groups, while sparsely deposited calcium carbonate was observed in the TA-downregulated group. The C: N ratio in the shell of individuals from the TA-downregulated group was significantly lower than that of the other two groups, indicating that less inorganic carbon was added to the shell. As a result, abalone grew lighter and thinner shells in TA-downregulated seawater. Although seawater was not acidified, TA downregulation also caused a reduction in the calcium carbonate saturation state (Ω), which induced the erosion of the surface shell and the interruption of calcium carbonate generation. In conclusion, although seawater pH remained at ambient levels, the lowered CO2 buffering capacity and Ω induced by seawater TA downregulation also showed a detrimental effect on the growth and calcification of Pacific abalone. The impact of ocean acidification on the growth of abalone should not be assessed using only seawater pH and/or pCO2 but rather taking into account all of carbonate chemistry, particularly the CO2 buffering capacity. Abalone cultivation is suggested to be carried out in seawater with a higher level of CO2 buffering capacity and Ω, which can be achieved through integrated culture with seaweed or increasing the seawater TA level.

In cooperation with the Foundation for the Advancement of Science and the Atomic Energy Agency
« Research » conducted a study on the impact of « acidification » on shrimp
The Kuwait Institute for Scientific Research (KISR), in cooperation with the Kuwait Foundation for the Advancement of Sciences (KFAS) and the International Atomic Energy Agency (IAEA), completed a study project to investigate the impact of ocean acidification and ocean surface warming on the growth and abundance of local shrimp.
In turn, the head of the project, researcher Lamia Muslim at the Center for Environmental and Life Sciences Research at the Institute, said that there are many animals that contain in their skeleton or shell calcium carbonate, and changes in the pH of water can negatively affect these organisms, especially in the early stages of their life. The sea and some phytoplankton species, but that does not mean that this is a positive thing because the increased growth of these organisms can disrupt the food chain, biodiversity and ecosystem mechanisms and construction.
She added that the presence of large amounts of carbon dioxide in the atmosphere leads to the occurrence of global warming and the rise of the surface of the oceans by between one and three degrees Celsius, and the rise of the water level to an amount ranging from 0.18 to 0.79 meters, which in turn leads to acidification and warming of the surface of the oceans, and therefore to change the chemistry of the ocean and threaten marine ecosystems.
She pointed out that the shrimp mothers were collected from Kuwaiti territorial waters during the breeding season to obtain eggs and shrimp larvae in sufficient numbers to conduct experiments on all stages of shrimp age, as the study experiments were conducted in the laboratories of the Institute in a controlled system simulating the expected climate changes in the future.
The results of the study confirmed that the warming of the surface of the oceans could have a greater impact than ocean acidification on the early life stages of shrimp larvae, as shrimp larvae exposed to high temperatures showed accelerated growth rates to reach the sizes of older shrimp, but with lower survival rates, it is very likely that lower survival and growth rates under future climate scenarios may lead to the emergence of smaller shrimp larvae. These larvae will undergo multiple molting processes over their life cycle making them vulnerable; furthermore, the study results suggest additional effects of combined exposure to ocean surface warming and acidification on egg-hatching success, survival, and shrimp larval development.
Al-Musallam said: “The study is fully consistent across the entire life cycle of the M Nair shrimp, where high mortality of larvae at low pH and high water temperature indicates a possible collapse of this species of crustacean under conditions of increased ocean acidification and future warming of the ocean surface, which also leads to a significant reduction in shrimp stocks in the Arabian Gulf due to overfishing or reduced larval growth due to climate change. ”
For his part, dr.
Dr. Saifuddin Iqbaluddin, from the Center for Environmental and Life Sciences Research, said experts regularly measure water temperature and pH levels and look at how marine life might respond to these changes in the coming decades.

Seagrass meadows as ocean acidification refugia for sea urchin larvae

Higlights

  • Sea urchin larvae were grown at ambient or low pH in tanks with or without plants.
  • Plant photosynthesis increased pH and altered seawater chemistry at both pH levels.
  • Positive effects of plant metabolism on larval development and growth at low pH
  • Seagrass meadows as a tool against climate-driven loss of calcifying species

Abstract

Foundation species have been widely documented to provide suitable habitats for other species by ameliorating stressful environmental conditions. Nonetheless, their role in rescuing stress-sensitive species from adverse conditions due to climate change remains often unexplored. Here, we performed a mesocosm experiment to assess whether the seagrassPosidonia oceanica, through its photosynthetic activity, could mitigate the negative effects of ocean acidification on larval development and growth of the calcifying sea urchinParacentrotus lividus. Sea urchin larvae at early and late developmental stages that are generally associated to benthic habitats, were grown in aquaria with or without P. oceanica plants, under ambient or low pH conditions predicted by the end of the century under the worst climate scenario (RCP8.5). The percentage of abnormal larvae and their total body length under different experimental conditions were assessed on early- (i.e., pluteus; 72 h post-fertilization) and final-developmental stages (i.e., echinopluteus; 30 days post-fertilization), respectively. The presence of P. oceanica increased mean daily pH values of ∼0.1 and ∼0.15 units at ambient and low pH conditions, respectively, compared with tanks without plants. When grown at low pH in association with P. oceanica, plutei showed a ∼23 % reduction of malformations and echinoplutei a ∼34 % increase in total body length, respectively, compared with larvae developing in tanks without plants. Our results suggest that P. oceanica, by increasing pH and altering seawater carbonate chemistry through its metabolic activity, could buffer the negative effects of ocean acidification on calcifying organisms and could, thus, represent a tool against climate-driven loss of biodiversity.

Rising average temperature, melting sea ice Arctic waters acidify faster than other oceans
Scientists warn that this acidification could worsen in the coming decades if sea ice continues to melt.
The rapid melting of Arctic sea ice caused by global warming makes it easier to absorb carbon dioxide from the atmosphere, which accelerates the rate of ocean acidification.

Most people agree that the increase in carbon dioxide in the atmosphere caused by human activities is not only absorbed by forests, but also nearly a third of the world ’ s oceans. However, it is precisely because of the large increase in carbon dioxide needed to be absorbed that ocean acidification is rapidly worsening, especially in the polar regions.
Researchers from the Institute of Polar and Ocean Studies at Jimei University in Xiamen and the School of Marine Science and Policy at Dalawi University have found that rapid melting of Arctic sea ice due to global warming is exposing the lower sea water to the air, making it easier to absorb atmospheric carbon dioxide, thereby accelerating the rate of acidification.
Scientists have long believed that the rate of ocean acidification is related to the rate of increase in carbon dioxide in the atmosphere, but the team looked at data from 1994 to 2020 and found that the Arctic Ocean acidified about three to four times faster than the Atlantic Ocean, the Pacific Ocean and even the Antarctic Ocean.
Scientists warn that this acidification could worsen in the coming decades if sea ice continues to melt.
Because of the Arctic amplification effect, the Arctic Circle has warmed up to four times the global average in the past 43 years, and as sea ice melts, the sea water will continue to be diluted and the pH will decrease, which will also reduce the ability of the sea to resist acidification.
In addition to the coral reefs that are most directly impacted, ocean acidification affects a wide range of areas and may even make some metals more toxic, although more detailed results may be needed for further analysis.
