5,000 percent increase in native trees on rat-free palmyra atoll

Tue, 17 Jul 2018 14:25:35 EDT ~ New research demonstrates dramatic positive benefits for native trees following rat removal at Palmyra Atoll, a magnificent National Wildlife Refuge and natural research laboratory located about 1000 miles south of Hawaii. For five native tree species, including Pisonia grandis, fewer than 150 seedlings were counted in the presence of rats, and more than 7700 seedlings were counted five years after rats were removed.

Protecting tropical forest carbon stocks may not prevent large-scale species loss

Mon, 16 Jul 2018 16:45:20 EDT ~ As the world seeks to curb human-induced climate change, will protecting the carbon of tropical forests also ensure the survival of their species? A study suggests the answer to this question is far from straightforward. Forests with the greatest carbon content do not necessarily house the most species, meaning carbon-focused conservation can miss large swathes of tropical forest biodiversity. Find out more...

Australia has a new venomous snake -- And it may already be threatened

Mon, 16 Jul 2018 10:35:54 EDT ~ The ink has not yet dried on a scientific paper describing a new species of snake, yet the reptile may already be in danger of extinction due to mining. A team of biologists discovered a new species of bandy-bandy snake at Weipa on the west coast of the Cape York Peninsula. Find out more...

Rats trail behind shrews, monkeys, and humans in visual problem solving

Thu, 12 Jul 2018 17:22:10 EDT ~ Rats take a fundamentally different approach toward solving a simple visual discrimination task than tree shrews, monkeys, and humans, according to a comparative study of the four mammal species. The work could have important implications for the translation of research in animal models to humans. Find out more...

Tree shrews can tolerate hot peppers: Mutation in pain receptor makes peppery plant palatable

Thu, 12 Jul 2018 14:16:36 EDT ~ Almost all mammals avoid eating chili peppers and other 'hot' foods, because of the pain they induce. But not the tree shrew, according to a new study. The researchers found that this close relative of primates is unaffected by the active ingredient in chili peppers due to a subtle mutation in the receptor that detects it. Find out more...

New evidence of two subspecies of American pikas in Rocky Mountain National Park

Thu, 12 Jul 2018 12:39:45 EDT ~ Rocky Mountain National Park provides habitat for not one, but two subspecies of the American pika. Find out more...

Mapping species range shifts under recent climatic changes

Thu, 12 Jul 2018 10:05:02 EDT ~ The inclusion of taxon-specific sensitivity to a shifting climate helps us understand species distributional responses to changes in climate. Find out more...

Invasive plants adapt to new environments

Thu, 12 Jul 2018 10:04:40 EDT ~ Invasive plants have the ability to adapt to new environments -- and even behave like a native species, according to new research. Find out more...

Eradicate rats to bolster coral reefs

Wed, 11 Jul 2018 13:12:01 EDT ~ New research has confirmed that invasive rats decimate seabird populations, with previously unrecognized consequences for the extensive coral reefs that encircle and protect these islands. Invasive predators such as rats -- which feed on bird eggs, chicks, and even adults birds -- are estimated to have decimated seabird populations within 90 percent of the world's temperate and tropical island groups, but until now the extent of their impact on surrounding coral reefs wasn't known.

The first endemic Baltic Sea fish species received its name

Wed, 11 Jul 2018 10:56:59 EDT ~ Researchers have discovered and named a new endemic fish species in the Baltic Sea, the 'Baltic flounder,' Platichthys solemdali. Find out more...
