Is Warming Bringing a Wave of New Diseases to Arctic Wildlife?…

Intro: Rapid warming and vanishing sea ice in the Arctic has enabled new species, from humpback whales to white-tailed deer, to spread northward. Scientists are increasingly concerned that some of these new arrivals may be bringing dangerous pathogens that could disrupt the region’s fragile ecosystems… Read the full article here at Yale Environment 360: https://e360.yale.edu/features/is-warming-bringing-a-wave-of-new-diseases-to-arctic-wildlife […]

Eating in 10-hour window can override disease-causing genetic defects, nurture health…

Summary:   Scientists found that mice lacking the biological clocks thought to be necessary for a healthy metabolism could still be protected against obesity and metabolic diseases by having their daily access to food restricted to a 10-hour window… Read all about this study by the Salk Institute here: https://www.sciencedaily.com/releases/2018/08/180831130131.htm

Species-rich forests better compensate environmental impacts…

Summary:  To offset CO2 emissions, China is reforesting. If a mixture of tree species instead of monocultures were planted, much more carbon could be stored. An international team has shown that species-rich forest ecosystems take up more CO2 from the atmosphere and store more carbon in biomass and soil, making them more effective against climate […]

In Defense of Biodiversity: Why Protecting Species from Extinction Matters…

A number of biologists have recently made the argument that extinction is part of evolution and that saving species need not be a conservation priority. But this revisionist thinking shows a lack of understanding of evolution and an ignorance of the natural world…  Read the full article here at Yale Environment 360: http://e360.yale.edu/features/in-defense-of-biodiversity-why-protecting-species-from-extinction-matters

Humans at maximum limits for height, lifespan and physical performance, study suggests…

Summary:  Newly emerging trends in data suggests humans may have reached their maximum limits for height, lifespan and physical performance. These biological limitations may be affected by anthropogenic impacts on the environment – including climate change – which could have a deleterious effect on these limits. This review is the first of its kind spanning […]

How Growing Sea Plants Can Help Slow Ocean Acidification by Nicola Jones: Yale Environment 360…

“Researchers are finding that kelp, eelgrass, and other vegetation can effectively absorb CO2 and reduce acidity in the ocean. Growing these plants in local waters, scientists say, could help mitigate the damaging impacts of acidification on marine life…” Source e360.yale.edu (Yale Environment 360): How Growing Sea Plants Can Help Slow Ocean Acidification by Nicola Jones: […]
