Nearly 47,000 hours of audio recording reveals vehicles, air craft are primary sources of human-caused noise in U.S. national parks

By University of Alberta 9/18/2019 A new technique developed by University of Alberta biologists can determine whether certain fish populations are native to lakes in national parks. The technique takes a molecular approach, using environmental DNA (eDNA) analysis of lake sediment to provide important historical information necessary for determining the conservation status of many lakes in Western Canada. “When you…

By CU Denver 9/13/2019 Ecologists have long tried to understand and anticipate the compositional change of plant species, especially now, as climate and land usage disrupts the way in which plants colonize and expand their communities. Called plant succession, the study of predicting plant communities through time is one of ecology’s oldest pursuits. In 2016, Brian Buma, PhD, assistant professor of…

By Michael Kaspari Lab 9/13/2019 One paradox in the recent flurry of papers reporting insect declines is that insects—ectotherms that rely on external sources of heat—are often predicted to benefit as their environment warms. In an open access paper accepted as a Report in the journal Ecology  our team of ecologists—including Michael Weiser, Jelena Bujan, Karl Roeder, and Kirsten deBeurs—all from…

By The Conversation 9/11/2019 Sometimes even the largest natural wonders can remain hidden from human view for centuries. The Amazon is a dense place, full of life with new species of flora and fauna being discovered every other day. Now, using the same technology that takes driverless cars from A to B, we – led by Eric Gorgens and Diego…

ESA announces the publication of a new report, “Impacts to Wildlife of Wind Energy Siting and Operation in the United States,” in ESA’s Issues in Ecology publication.

By University of Arizona 9/10/2019 The iconic saguaros on Tumamoc Hill served as harbingers in new research which sought to predict how the desert species will fare in the hotter, drier climate of the future and how topography might mitigate the effects of climate change.   Lead author Susana Rodríguez-Buriticá and her team crunched the numbers in a 48-year-long dataset…

By the Swiss Federal Institute for Forest, Snow and Landscape Research 9/10/2019 The trade of forest tree seeds is, on a global scale, not as safe as previously believed. Researchers from CABI and, among other institutions, the Swiss Federal Institute WSL, revealed that insect pests and fungal pathogens associated with seeds pose a great risk to trees and forest ecosystems worldwide. Non-native…

By CNRS 9/4/2019 Gorillas are social animals, living in groups that females will migrate to join, becoming members of harems. Though some factors motivating these migrations were previously known, a research team affiliated with the CNRS and Université de Rennes 1 has just demonstrated that female gorillas are able to avoid conspecifics liable to transmit yaws, which leads to conspicuous…

By University of Connecticut 8/28/2019 Forests in the eastern United States that are structurally complex — meaning the arrangement of vegetation is varied throughout the physical space — sequester more carbon, according to a new study in Ecology, a journal of the Ecological Society of America. The study by researchers at the University of Connecticut, Virginia Commonwealth University, and Purdue University, demonstrates for…

Longfin smelt use a greater diversity of spawning areas than previously known, complicating current methods of population assessments and projections for the highly endangered fish.

By University of Wyoming 8/21/2019 For every acre of mule deer habitat taken by roads, well pads and other oil and gas development infrastructure in Wyoming’s Green River Basin, an average of 4.6 other acres of available forage is lost, according to new research by University of Wyoming scientists. That’s because deer avoid areas close to such human disturbance, even…

By Northern Arizona University 8/20/2019 When Jaime Yazzie began planning her research for her forestry thesis, her adviser asked her what species of trees she wanted to save. They would use a computer simulation to measure the effects of a warming, drying environment, and she needed to select which trees to preserve. “I was a little shocked,” Yazzie said. “In my…

By Pennsylvania State University 8/14/2019 LOUISVILLE, Ky. — A fisherman’s curiosity led to identification of the correlation between microbial communities in recreational freshwater locales and seasonal environmental changes, according to a team of researchers from Penn State. Zachary Weagly, a 2018 graduate of Penn State Berks and an avid fisherman, noticed that the quality of the water where he fished changed with…

By Pennsylvania State University 8/12/2019 LOUISVILLE, Ky. — Everywhere you go there are stormwater detention basins built near large construction projects intended to control the flow of rainwater and runoff. Now, those basins might help in controlling nitrogen runoff into rivers and lakes, according to Lauren E. McPhillips, assistant professor of civil and environmental engineering at Penn State. Speaking today (Aug….

By Virginia Commonwealth University 8/12/2019 Forests in the eastern United States that are structurally complex — meaning the arrangement of vegetation is highly varied — sequester more carbon, according to a new study led by researchers at Virginia Commonwealth University. The study demonstrates for the first time that a forest’s structural complexity is a better predictor of carbon sequestration potential than tree species…

By UC Riverside 8/8/2019 They outlived mammoths and saber-toothed tigers. But without dramatic action to reduce climate change, new research shows Joshua trees won’t survive much past this century. UC Riverside scientists wanted to verify earlier studies predicting global warming’s deadly effect on the namesake trees that millions flock to see every year in Joshua Tree National Park. They also…

Osvaldo Sala became President of the Ecological Society of America (ESA) August 16 during the Society’s annual meeting in Louisville, KY. Sala is the first Hispanic person to serve in this role in the organization’s over-100-year history.

The Ecological Society of America (ESA) will donate over $13,800 to Louisville Grows to offset the environmental costs of the society’s 104th Annual Meeting.

The first National Biodiversity Championship will be conducted this year in Louisville, Kentucky, August 11 – August 14, concurrent with the 2019 Annual Meeting for the Ecological Society of America.
