Waves of change: How sea-levels and climate altered the marine ecosystems at the South Pole 390-385 million years ago      (via sciencedaily.com)     Original source 

New research reveals a chain of environmental disasters. These took place in what is today's South Africa, during an ancient time period called the Early-Middle Devonian. The crises led to the extinction of a unique group of marine animals called the Malvinoxhosan biota.

Pinpointing the emergence of muddy flavors in your fish      (via sciencedaily.com)     Original source 

Many people have experienced a muddy off-flavor in farmed fish. While the aquaculture industry has known about the problem for 20 years, it continues to impact the consumption of otherwise healthy and potentially sustainable fish. Now, researchers have been able to pinpoint exactly when the off-flavors emerge. And this can make it easier to deal with the compounds that turn people away from farmed fish.

Drought conditions expose rivers to hotter water temperatures      (via sciencedaily.com)     Original source 

A new study reveals how reduced water flows and rising atmospheric temperatures are set to heat our rivers -- creating major challenges for aquatic life, ecosystems, and society.

New mollusk and crustacean species in symbiosis with worms in dead coral rocks      (via sciencedaily.com)     Original source 

The symbiotic communities of invertebrates in dead coral gravel on the shallow, warm-temperate coast of the Kii Peninsula in western Japan. New bivalve species and sideswimmer have been found to live communally with the greenish Bonellia spoonworm. Live-in symbionts share the burrows of other organisms in sand and mud on the seabed. However, studies on burrow niches in rigid substrates, such as rocks on the seabed, have been scarce.

Surprising discovery about coral's resilience could help reefs survive climate change      (via sciencedaily.com)     Original source 

A team has studied the mountainous star coral, Orbicella faveolata, to determine whether coral populations that have survived higher temperatures can pass their heat tolerance on to their offspring.  To the scientists' surprise, the results showed the opposite: The offspring from a population that is less heat-tolerant performed better when exposed to high temperatures than their counterparts from a heat-tolerant population. The findings counter the commonly held notion among scientists that if coral parents can handle the heat, so should their offspring.

Ocean circulation, ice melt and increasing tourism could all be contributing to Arctic microplastics      (via sciencedaily.com)     Original source 

Scientists measured microplastic concentrations in the highly productive Barents Sea and suggest that ocean circulation, ice melt, tourism, inadequate waste management, shipping and fishing are all likely contributors.

Study reveals our European ancestors ate seaweed and freshwater plants      (via sciencedaily.com)     Original source 

Researchers say they have found 'definitive' archaeological evidence that seaweeds and other local freshwater plants were eaten in the mesolithic, through the Neolithic transition to farming and into the Early Middle Ages, suggesting that these resources, now rarely eaten in Europe, only became marginal much more recently.

Unique marimo threatened by rising lake temperatures      (via sciencedaily.com)     Original source 

Rising lake water temperatures threaten the survival of marimo, unique algal balls found only in cold lakes. Researchers clarified that the warmer it gets, the more the inward decomposition outpaces the outward growth of these life forms, making them increasingly fragile.

Climate change coping mechanism discovered in humble algae      (via sciencedaily.com)     Original source 

One of the building blocks of ocean life can adapt to cope with the effects of climate change, according to new research. The discovery holds promises for biotechnology developments that could counter the negative effects of changing environmental conditions, such as ocean warming and even the reduction in the productivity of crops.

What phytoplankton physiology has to do with global climate      (via sciencedaily.com)     Original source 

Phytoplankton, tiny photosynthetic organisms in the ocean, play a crucial role in the global carbon cycle and influence Earth's climate. A new study reveals how variations in the physiology of phytoplankton, particularly regarding nutrient uptake, can impact the chemical composition of the ocean and even the atmosphere. This suggests that changes in marine phytoplankton physiology can affect global climate.

Killer whales' diet more important than location for pollutant exposure      (via sciencedaily.com)     Original source 

Both elegant and fierce, killer whales are some of the oceans' top predators, but even they can be exposed to environmental pollution. Now, in the largest study to date on North Atlantic killer whales, researchers report the levels of legacy and emerging pollutants in 162 individuals' blubber. The animals' diet, rather than location, greatly impacted contaminant levels and potential health risks -- information that's helpful to conservation efforts.

Remains of artificial turf is an important source of pollution of the aquatic environment      (via sciencedaily.com)     Original source 

Every year, around 1,200 and 1,400 artificial turf sports fields are installed in the European Union. These fields are made up of synthetic fibers, mainly plastics, that mimic the appearance of natural grass. Recently, scientists conducted a study that characterizes and quantifies the presence of artificial turf fibers in samples collected from surface waters of the Catalan coast and the Guadalquivir River. The findings indicate that artificial turfs can be an important source of pollution in the aquatic environment, accounting for up to 15% of the plastics larger than 5 mm in length that are found floating in the aquatic environment.

Study clearly identifies nutrients as a driver of the Great Atlantic Sargassum Belt      (via sciencedaily.com)     Original source 

Under normal conditions, the floating macroalgae Sargassum spp. provide habitat for hundreds of types of organisms. However, the Great Atlantic Sargassum Belt (GASB) that emerged in 2011 has since then caused unprecedented inundations of this brown seaweed on Caribbean coastlines, with harmful effects on ecosystems while posing challenges to regional economies and tourism, and concerns for respiratory and other human health issues.
