A wetter world recorded in Australian coral colony      (via sciencedaily.com)     Original source 

When climate scientists look to the future to determine what the effects of climate change may be, they use computer models to simulate potential outcomes such as how precipitation will change in a warming world. Some scientists are also looking at something a little more tangible: coral.

Fish species that move rapidly toward the poles due to global warming decline in abundance, study finds      (via sciencedaily.com)     Original source 

A new study has found a decline in the abundance of marine fish species that move rapidly toward the poles to escape rising sea temperatures. The researchers explain that many animal species are currently moving toward cooler regions as a result of global warming, but the velocity of such range shifts varies greatly for different species. Examining thousands of populations from almost 150 fish species, the researchers show that contrary to the prevailing view, rapid range shifts coincide with widescale population declines.

Eyes open and toes out of water: How a giant water bug reached the island of Cyprus      (via sciencedaily.com)     Original source 

A new visitor was reported on the coast of Cyprus, thanks to the growing power of citizen science. Researchers collected information and specimens through personal communication with amateur naturalists, but also through the internet, in order to compose the mosaic of repeated appearances of a giant water bug on the eastern shoreline of the island.

Global wildlife study during COVID-19 shows rural animals are more sensitive to human activity      (via sciencedaily.com)     Original source 

One of the largest studies on wildlife activity reveals that wild animals react differently to humans depending on where the animals live and what they eat. Bigger herbivores -- plant-eating animals like deer or moose -- tend to become more active when humans are around, while meat-eaters like wolves or wolverines tend to be less active, preferring to avoid risky encounters.

Even inactive smokers are densely colonized by microbial communities      (via sciencedaily.com)     Original source 

Everything is everywhere -- under certain conditions microbial communities can grow and thrive, even in places that are seemingly uninhabitable. This is the case at inactive hydrothermal vents on the sea floor. An international team is presently working to accurately quantify how much inorganic carbon can be bound in these environments.

Shark-bitten orcas in the Northeastern Pacific could be a new population of killer whale      (via sciencedaily.com)     Original source 

Researchers believe a group of killer whales observed hunting marine mammals including sperm whales, as well as a sea turtle, in the open ocean off California and Oregon could be a new population. Based on available evidence, the researchers posit that the 49 orcas could belong to a subpopulation of transient killer whales or a unique oceanic population found in waters off the coast of California and Oregon.

Diverse habitats help salmon weather unpredictable climate changes      (via sciencedaily.com)     Original source 

Restored salmon habitat should resemble financial portfolios, offering fish diverse options for feeding and survival so that they can weather various conditions as the climate changes, a new study shows.

Surprising insights about debris flows on Mars      (via sciencedaily.com)     Original source 

The period that liquid water was present on the surface of Mars may have been shorter than previously thought. Channel landforms called gullies, previously thought to be formed exclusively by liquid water, can also be formed by the action of evaporating CO2 ice, according to a new study.

Tropical birds could tolerate warming better than expected, study suggests      (via sciencedaily.com)     Original source 

We expect tropical animals to handle a certain degree of heat, but not wild swings in temperature. That seems to be true for tropical ectotherms, or 'cold-blooded' animals such as amphibians, reptiles, and insects. However, in a new study of 'warm-blooded' endotherms, a research team found tropical birds can handle thermal variation just fine.

Sleep-wake rhythm: Fish change our understanding of sleep regulation      (via sciencedaily.com)     Original source 

Researchers have discovered that some fish -- unlike humans -- do not need orexin to stay awake. This molecule was thought to be necessary for normal wake and sleep rhythms in vertebrates. Humans without orexin suffer from narcolepsy.

Training dairy cows with positive reinforcement can turn otherwise stressful events into play      (via sciencedaily.com)     Original source 

Dairy cows receive a huge amount of care during their lives on a farm, but procedures, especially restraining during procedures, can be stressful for some animals. Positive reinforcement training -- or training with a reward to achieve a desired behavior -- has shown promise to reduce this fear in other species.

Unique way to track carbon emissions in bodies of water      (via sciencedaily.com)     Original source 

Carbon dioxide emissions are not typically associated with water ways, like streams and rivers, but emerging research shows that water bodies play an important role in storing and releasing carbon dioxide. As many states look for cost-effective ways to mitigate climate change, scientists looked at a way to optimize CO2 sensors to better measure carbon dioxide emissions in lotic, or moving, bodies of water offering a new tool that can help provide valuable information for everything from land use to climate action plans.
