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.
Vast ranges of volcanoes hidden under the oceans are presumed by scientists to be the gentle giants of the planet, oozing lava at slow, steady rates along mid-ocean ridges. But a new study shows that they flare up on strikingly regular cycles, ranging from two weeks to 100,000 years--and, that they erupt almost exclusively during the first six months of each year.
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.
New research by the University of Sheffield has warned of the increasing risk of extinction to our marine life.
The Tar Sands in Alberta, potential development in the Ring of Fire in northern Ontario, declining timber harvest and farming - human activity is transforming Canada's landscape, yet many of the country's aquatic resources remain unprotected, according to research by ecologists at the University of Toronto.
As the climate warms, glaciers and other terrestrial ice reservoirs will release massive amounts of organic carbon into the water circulation. Just how much and how quickly it will be released is the focus of a recent Nature Geoscience publication.
Students in a Northern Arizona University undergraduate conservation biology class have been studying impacts of a prolific bison herd near the Grand Canyon’s North Rim.
As the Earth warms and glaciers all over the world begin to melt, researchers and public policy experts have focused largely on how all of that extra water will contribute to sea level rise.
A total of 10% of adults living in developed countries practice recreational fishing, which in the Mediterranean Sea represents around 10% of the total production of fisheries. Despite its importance, this fishing is not as controlled or studied as professional fishing. For the first time, a study examines this activity, whose effects are increasingly more similar to traditional fishing. For this reason, scientists demand greater control.
After a forest fire burns a large swath across timberlands, logging companies often are not far behind. They come in to do what is called salvage logging--salvaging the timber that has not been completely destroyed by the fire.
