The agricultural development of a region of eastern China is ecologically unsustainable and actions are needed soon to reverse its decline, according to a new study by geographers at the University of Southampton.
SFU biologist Isabelle Côté has co-authored a new study that finds little would be lost by eliminating high seas fishing.
Healthy forest ecosystems need dead wood to provide important habitat for birds and mammals, but there can be too much of a good thing when dead wood fuels severe wildfires. A scientist with the U.S. Forest Service's Pacific Southwest Research Station (PSW) compared historic and recent data from a forest in California's central Sierra Nevada region to determine how logging and fire exclusion have changed the amounts and sizes of dead wood over time. Results were recently published in Forest Ecology and Management.
Natural seepage of methane offshore the Arctic archipelago Svalbard has been occurring periodically for at least 2,7 million years. Major events of methane emissions happened at least twice during this period, according to a new study.
Bremerhaven/Sylt, 3rd February 2015. Researchers at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have shown that three-spined sticklebacks in the North Sea pass on information concerning their living environment to their offspring, without genetic changes.
Many marine organisms--such as coral, clams, mussels, sea urchins, barnacles, and certain microscopic plankton--rely on equilibrated chemical conditions and pH levels in the ocean to build their calcium-based shells and other structures. A new analysis published in the journal Environmental Science and Technology provides a holistic analysis of how species will be affected worldwide under different climate scenarios.
Kansas State University scientists and collaborators have developed a new method for studying a variety of streams--including tropical, prairie or forested streams--across continents.
The American pika, a small animal with a big personality that has long delighted hikers and backpackers, is disappearing from low-elevation sites in California mountains, and the cause appears to be climate change, according to a new study.
Ecologists sometimes look to mussel species, a well-studied and foundational genus in estuaries, as model organisms for assessing the condition of coastal habitats, which are crucial for people and well as the broader environment.
The Earth's crust under Iceland is rebounding as global warming melts the island's great ice caps, a University of Arizona-led team reports in an upcoming issue of Geophysical Research Letters.
