Radiocarbon dating of five large and potentially old sessile oaks from Aspromonte National Parks revealed a long lifespan ranging from 934 ± 65 to 570 ± 45 years.
Meals are typically family affairs for zebras, gazelles, cape buffalo and other grazing species in the African Serengeti, but in one of the first studies of its kind, ecologists have found grazing species can be more willing to share meals in areas frequented by lions.
A new study suggests that future reductions in seasonal snowpack as a result of climate change may negatively influence forest growth in semi-arid climates, but less so in wetter climates.
As the Discovery Channel hosts its traditional summer Shark Week (Aug. 9-16) about innovative shark research and insights on shark species, CSUF marine scientists and their students are working on research projects to learn more about these misunderstood predators of the seas.
In a new study investigating human impacts on resource fish biomass on the island of Hawaii, researchers from the Arizona State University Center for Global Discovery and Conservation Science and Hawaii Division of Aquatic Resources observed an alarming 45% decrease in fish biomass over a decade of surveys.
Climate change has increased the productivity of forests, according to a new study that synthesizes hundreds of thousands of carbon observations collected over the last quarter century at the Harvard Forest Long-Term Ecological Research site.
Arctic mosquito populations appear to be driven by food quality rather than predator density, according to a study published in Ecology.
Researchers at the National Wildlife Research Center found the use of a rear-facing LED light bar resulted in fewer dangerous deer-vehicle interactions. The reduction in dangerous interactions appeared to be driven by fewer instances of immobility or “freezing” behavior by deer when the light bar was used.

by Utah State University 7/20/2020 The Ecological Society of America (ESA) will be holding its first ever completely virtual annual meeting on Aug. 3-6, 2020. Utah State University has impressive representation, with 60 scheduled talks and posters from over 50 student, post-doctoral and faculty researchers. This year’s meeting format makes participation easy. All talks and posters will be available online beginning Monday,…
By U.S. Forest Service Southern Research Station 7/7/2020 In parts of the southeastern U.S., one unlikely forest type has great potential for extreme fire behavior: hardwood-cypress swamps. These shallow wetlands can work with their more frequently burned neighbors, pine flatwoods, to wreak havoc by easily igniting and sustaining tremendous wildfires, thus depleting carbon storage in these forests. Hardwood-cypress swamps and…
By Oregon State University 7/13/2020 CORVALLIS, Ore. – Caspian terns feeding on young fish have a significant impact on runs of steelhead in the Columbia River, according to a new paper from scientists at Oregon State University. Through detailed analysis of steelhead survival and Caspian tern predation rates, the researchers found that the birds are not only preying on fish…
by the University of Georgia 7/13/2020 Athens, Ga. – The ringtail, a relative of the raccoon, is a nocturnal creature that lives in arid regions of western North America. Despite their solitary nature, they have long been known to inhabit national park buildings in southern Utah, where they scavenge food from trash cans. This makes them an excellent subject for…
by the University of Montana 7/1/2020 FLATHEAD LAKE – In a new study published in the scientific journal Ecology, researchers from the University of Montana’s Flathead Lake Biological Station may have unlocked a mystery surrounding unique aquatic insects in the Flathead watershed. “There’s a surprising adaptation of stoneflies in alluvial aquifers that allows them to use low-oxygen or oxygen-free environments,” said…
By Michigan State University 6/30/2020 How many elephants are in Tanzania? How many trees are in the Amazon? How many tuna are in the Atlantic? While we probably wouldn’t know the answers to these questions on an individual level, new research indicates that if we collectively consider all our wrong answers, as a group we would probably arrive at the…
By University of Wyoming 6/29/2020 A University of Wyoming researcher and her Ph.D. student have spent the last three years studying the decline of the Western bumblebee. The two have been working with a group of bumblebee experts to fill in gaps of missing information from previous data collected in the western United States. Their goal is to provide information…
By The Swiss Federal Institute for Forest, Snow and Landscape Research 6/29/2020 Plants are sprouting earlier and earlier due to climate change, but for roe deer, the timing of fawning is advancing more slowly. This results in changes to the food supply during critical periods of the fawns’ growth. Deer populations at lower altitudes are particularly affected, according to a…
