New study finds that the nutritional value of prey within a single species can widely vary, offering key insights for food web dynamics and ecosystem change The hunt is on and a predator finally zeroes in on its prey. The animal consumes the nutritious meal and moves on to forage for its next target. But how much prey does a predator need to consume? Following a period of massive starvation among animals living along the California coast, University of California…
Twiss and his colleagues documented very high concentrations of algae thriving in the water below the ice and even within the ice itself — this despite dark…
With luck, that analysis will yield a record of past climate and environmental changes in the region for several centuries, and perhaps even covering the last…
Of all the habitable parts of our planet, one ecosystem still remains largely unexplored and unknown to science: the igneous ocean crust.This rocky realm of…
A new analysis of satellite data from the late 1990s documents for the first time the “uplift” of ground above a site of underground nuclear testing, providing…
The U.S. Geological Survey and University of Montana study not only showed that the abundance of deciduous trees and their associated songbirds in mountainous…
One tiny insect, the hemlock woolly adelgid, is to blame. The Asian insect first appeared in the eastern U.S. in Richmond, Va., in the 1950s. In 2003, it…
When scientist David Valentine and colleagues published results of a study in early 2011 reporting that bacterial blooms had consumed almost all the deepwater…
Scientists have revealed details of the world's most extreme deep-sea volcanic vents, 5 kilometres down in a rift in the Caribbean seafloor. The undersea hot…
An interactive tool developed by researchers from the USDA Forest Service’s Pacific Southwest Research Station (PSW) will help wind energy facility operators…
The striking black-and-yellow snake is called Matilda's horned viper. It measures 2.1 feet (60 centimeters) and has horn-like scales above its eyes. The…
The Earth's current warm period that began about 11,000 years ago should give way to another ice age within about 1,500 years, according to accepted…
Summertime hail could all but disappear from the eastern flank of Colorado's Rocky Mountains by 2070, according to a new modeling study by scientists from NOAA…
With the publication of “Continent-wide response of mountain vegetation to climate change,” scheduled for Advance Online Publication (AOP) in Nature Climate…
This greatly increases the risk that a new wave of invasives will overrun native ecosystems in the way kudzu, Oriental bittersweet and purple loosestrife have…
A new study in Nature Climate Change aims to present a more complete picture – to incorporate other characteristics of ecosystems that also influence climate.“We know that forests store a lot of carbon and clearing a forest releases carbon dioxide into the atmosphere and contributes to climate change,” said University of Illinois postdoctoral researcher Kristina Anderson-Teixeira, who pioneered the new approach with plant biology and Energy Biosciences Institute professor Evan DeLucia. “But ecosystems provide other climate regulation services as well.”…
Led by researchers from the Austrian Academy of Sciences and the University of Vienna, biologists from 13 different countries in Europe analysed 867 vegetation…
