Increasing seal population will not harm largest fish stocks in the Baltic

Mon, 10 Dec 2018 07:25:30 EST ~ Seals feeding on fish does not decrease fish stocks of Baltic cod, herring and sprat the most -- climate change, nutrient load and fisheries do, shows a new study. Find out more...

Biggest mass extinction caused by global warming leaving ocean animals gasping for breath

Thu, 06 Dec 2018 14:12:25 EST ~ By combining ocean models, animal metabolism and fossil records, researchers show that the Permian mass extinction in the oceans was caused by global warming that left animals unable to breathe. As temperatures rose and the metabolism of marine animals sped up, the warmer waters could not hold enough oxygen for their survival. Find out more...

Acrobatic geckos, highly maneuverable on land and in the air, can also race on water

Thu, 06 Dec 2018 12:00:22 EST ~ Asian geckos were observed running over water at nearly a meter per second, as fast as on land. Lab experiments show how. They get support from surface tension but also slap the water rapidly with their feet. They also semi-plane over the surface and use their tail for stabilization and propulsion. They thus sit between insects, which use only surface tension, and larger animals, which run upright via foot slapping alone. Find out more...

Mitigating the effect of climate change on sea turtles

Thu, 06 Dec 2018 11:59:29 EST ~ New research has reported effective conservation strategies that can mitigate the impacts of climate warming on sea turtle nesting success. Find out more...

Parrot genome analysis reveals insights into longevity, cognition

Thu, 06 Dec 2018 11:48:29 EST ~ Parrots are famously talkative, and a blue-fronted Amazon parrot named Moises -- or at least its genome -- is telling scientists volumes about the longevity and highly developed cognitive abilities that give parrots so much in common with humans. Perhaps someday, it will also provide clues about how parrots learn to vocalize so well. Find out more...

Industrial fisheries are starving seabirds all around the world

Thu, 06 Dec 2018 11:47:26 EST ~ Industrial fisheries are starving seabirds like penguins and terns by competing for the same prey sources. Seabirds are now the most threatened bird group. Find out more...

Could algae that are 'poor-providers' help corals come back after bleaching?

Thu, 06 Dec 2018 11:47:02 EST ~ How much of a reef's ability to withstand stressful conditions is influenced by the type of symbiotic algae that the corals hosts? New work investigates how the nutrients algae share with their coral hosts varies between species and what this could mean for a coral's ability to survive in a changing climate. They determined that in the wake of a bleaching event, even an algal tenant that's poor provider may be better than no provider. Find out more...

229 new species described by the California Academy of Sciences in 2018

Wed, 05 Dec 2018 17:19:19 EST ~ In 2018, researchers at the California Academy of Sciences added 229 new plant and animal species to our family tree, enriching our understanding of Earth's complex web of life and strengthening our ability to make informed conservation decisions. The new species include 120 wasps, 34 sea slugs, 28 ants, 19 fish, seven flowering plants, seven spiders, four eels, three sharks, two water bears, one frog, one snake, one seahorse, one moss, and one liverwort plant.

Soft tissue shows Jurassic ichthyosaur was warm-blooded, had blubber and camouflage

Wed, 05 Dec 2018 13:41:18 EST ~ An ancient, dolphin-like marine reptile resembles its distant relative in more than appearance, according to an international team of researchers. Molecular and microstructural analysis of a Stenopterygius ichthyosaur from the Jurassic (180 million years ago) reveals that these animals were most likely warm-blooded, had insulating blubber and used their coloration as camouflage from predators.

30 years of experimental evolution results in a new sex chromosome

Wed, 05 Dec 2018 13:40:47 EST ~ Researchers report new findings of an experimental evolutionary project that ran for 30 years on the genomic mechanisms of sex determination in swordtail fish. Find out more...
