In the Amazon, protected areas often lose out when the search for energy is on

By Florida International University 10/7/2019 Addressing policy “blind spots” that allow energy production and mineral exploration to trump environmental protection could help improve the outlook for conservation in the Amazon Basin, according to a new study. The production of new dams and the search for oil and natural gas, while often beneficial for people, can harm the environment. Dams block…

Fish DNA in lake sediment can help determine native species, study shows

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…

Ecologist revives world’s longest running succession study

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…

As ecosystems heat and green, ant abundance and diversity increases; but too much heat and these communities lose colonies and species

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…

Topography Could Save Sensitive Saguaros as Climate Changes

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…

Global trade of tree seeds can introduce harmful pests

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…
