Warming Signs: How Diminished Snow Cover Puts Species in Peril

Tue, 16 Jan 2018 09:18:00 EST

The wolverine is highly adapted to life in a snowy world. It has thick fur and snowshoe-like feet, and it dens high in the mountains as a way to avoid predators that aren’t as nimble in deep snow and to provide its kits with insulation from the bitter high-elevation cold.(image)



As Cli­mate is Warm­ing Up, More Bird Nests Are Des­troyed in Finnish Farm­land

Fri, 12 Jan 2018 11:52:00 EST

Finnish farmers are adapting to the warming climate by anticipating the time when they sow their fields in the spring. At the same time, birds have also advanced the time of breeding as the spring temperatures are becoming milder in response to climate change.(image)



Rising temperatures turning major sea turtle population female

Thu, 11 Jan 2018 14:22:00 EST

Scientists have used a new research approach to show that warming temperatures are turning one of the world’s largest sea turtle colonies almost entirely female, running the risk that the colony cannot sustain itself in coming decades, newly published research concludes. (image)



Pacific Northwest Salmon Species Has Lost Two-Thirds of Its Genetic Diversity

Thu, 11 Jan 2018 13:52:00 EST

Chinook salmon, an iconic species in the Pacific Northwest that supports a major fishery industry and indigenous traditions, have lost up to two-thirds of their genetic diversity over the past 7,000 years, according to a new study. Scientists warn the loss could make it difficult for the species to cope with warming global temperatures and ocean acidification — environmental changes that are already impacting the fish today.(image)



Study finds body size of marine plankton, currents keys to dispersal in ocean

Wed, 10 Jan 2018 15:03:00 EST

When it comes to marine plankton, the smaller you are the farther you travel. A new international study found that the size of plankton, and the strength and direction of currents, are key to how they are dispersed in the ocean – much more so than physical conditions including differences in temperature, salinity and nutrient availability.(image)



The ecological costs of war in Africa

Wed, 10 Jan 2018 15:03:00 EST

When Josh Daskin traveled to Mozambique’s Gorongosa National Park in 2012, its iconic large animals were returning from the brink of extinction. Gorongosa, among Africa’s most spectacular wildlife preserves until the 1970s, had been devastated by an anti-colonial war of liberation followed by a ghastly 15-year civil war — a one-two punch that exterminated more than 90 percent of the park’s wildlife.(image)



More roads in grizzly bear habitat means more deaths

Wed, 10 Jan 2018 08:20:00 EST

It’s simple math, says a University of Alberta conservation biologist. More roads equals fewer grizzly bears.In a recent study examining a non-invasive DNA (hair collection) dataset of grizzly bear activity in British Columbia, Clayton Lamb and his colleagues determined what scientists have long suspected: higher road density leads to lower grizzly bear density—a critical problem for a species still rebounding from a long period of human persecution.(image)
