High levels of microplastics found in Northwest Atlantic fish

A new study sheds light on the magnitude of microplastic pollution in our oceans. The study, published today in open-access journal Frontiers in Marine Science, found microplastics in the stomachs of nearly three out of every four mesopelagic fish caught in the Northwest Atlantic -- one of the highest levels globally. These findings are worrying,...

'Evolutionary rescue' areas for animals threatened by climate change

[unable to retrieve full-text content]As winters arrive later and snow melts earlier, the worldwide decrease in snow cover already may have dramatic impacts on animals that change coat colors with the seasons. An international scientific team has set out to discover whether adaptive evolution can rescue these animals in the face of rapidly changing climate....

World's most venomous spiders are actually cousins

[unable to retrieve full-text content]Two lineages of dangerous arachnids found in Australia -- long classified as distantly related in the official taxonomy -- are, in fact, relatively close evolutionary cousins. The lineages include the most venomous spiders in the world. The findings could help in the development of novel antivenoms, as well as point to...

Hunting is changing forests, but not as expected

[unable to retrieve full-text content]In many tropical forests, over-hunting is diminishing the populations of animals who are vital for dispersing the seeds of woody plants. Those same plants are vital for carbon storage and previous theoretical modeling studies predicted dire consequences to defaunation, this research suggests otherwise. Instead the data shows the effects on the...
