Moose and sawflies on the same pine – how do they interact?
By Swedish University of Agricultural Sciences 10/29/2019 Although common, indirect interactions between taxonomically distant herbivores, such as mammals and insects, are less studied than interaction between taxonomically related species (insect–insect). In this study the Swedish University of Agricultural Sciences and the Max Planck Institute for chemical ecology in Germany show that sawfly performance was enhanced on trees browsed by moose….
ISU Professor Aho studies how airborne bacteria, fungi help it rain and snow
By Idaho State University 11/5/2019 POCATELLO – Most people don’t think of weather as having a biological component and aren’t aware of the role airborne bacteria and fungi have in helping create rain and snow. But Ken Aho, Idaho State University associate professor of biological sciences, studies this phenomenon. “Weather is not as simple as we think – it is…
Satellites are key to monitoring ocean carbon
By University of Exeter 11/4/2019 Satellites now play a key role in monitoring carbon levels in the oceans, but we are only just beginning to understand their full potential. Our ability to predict future climate relies upon being able to monitor where our carbon emissions go. So we need to know how much stays in the atmosphere, or becomes stored in the oceans or…
Best of Frenemies: Unexpected Role of Social Networks in Ecology
By UC Davis 11/1/2019 Social networking, even between competing species, plays a much bigger role in ecology than anyone previously thought, according to three biologists at the University of California, Davis. “There’s mounting evidence that different species pay attention to each other in the wild, especially if they share predators,” said Mike Gil, postdoctoral researcher at UC Davis. “The theory…
New studies attribute warming waters, local differences in oceanography to rise and fall of American lobster populations in the Gulf of Maine
By University of Maine 10/24/2019 Two new studies published by University of Maine scientists are putting a long-standing survey of the American lobster’s earliest life stages to its most rigorous test yet as an early warning system for trends in New England’s iconic fishery. The studies point to the role of a warming ocean and local differences in oceanography in…
GBR island coral decline
By James Cook University 10/25/2019 A long-term study of coral cover on island groups of the Great Barrier Reef has found declines of between 40 and 50 percent of live, hard corals at inshore island groups during the past few decades. Scientists from the ARC Centre of Excellence for Coral Reef Studies at James Cook University (Coral CoE at JCU)…
UM Student Research Tests Ways to Reduce Errors in Wildlife Surveys
By Kasey Rahn, University of Montana 10/22/2019 MISSOULA – Research led by a University of Montana undergraduate student to identify less error-prone methods for performing wildlife surveys was published Oct. 20 in Ecological Applications. Biologists around the world use a variety of boots-on-the-ground field methods to survey animal populations. When extrapolated, these data provide population counts and other scientific information used to…
Removing Invasive Mice from the Farallon Islands Would Benefit Threatened Birds
By Point Blue Conservation Science 10/7/2019 Petaluma, CA–New research from Point Blue Conservation Science shows the significant negative impact that invasive, non-native house mice on the Farallon Islands are having to the threatened ashy storm-petrel. Original modeling by ecologists published today in the journal Ecosphere shows the potential impacts to the petrel’s population if mice are allowed to remain. The…
MSU researchers make surprising wolf diet discovery, highlight ecosystem complexities
By Mississippi State University 10/2/2019 STARKVILLE, Miss.—Mississippi State University researchers are shifting commonly held ideas about the diet of grey wolves in a newly published article gaining national attention. Published in the scientific journal “Ecology,” MSU assistant professor Brandon Barton’s Sept. 18 article “Grasshopper consumption by grey wolves and implications for ecosystems” details the unexpected effects of wolf reintroduction into the…
Seed availability hampers forest recovery after wildfires
By CU Boulder 10/2/2019 BOULDER, CO – A lack of tree seedling establishment following recent wildfires represents a crucial bottleneck limiting coniferous forest recovery in the western U.S., new CU Boulder-led research finds. The study, which was recently published in the journal Ecological Applications, examined burn-affected ponderosa pine and Douglas-fir stands in southern Colorado and northern New Mexico to better understand variation in…
UNH Researchers Find Northern Forests Have Lost Crucial Cold, Snowy Conditions
By University of New Hampshire 10/3/2019 DURHAM, N.H.—As the popular saying goes, “winter is coming,” but is it? Researchers at the University of New Hampshire have found clear signs of a decline in frost days, snow covered days and other indicators of winter that could have lasting impacts on ecosystems, water supplies, the economy, tourism and human health. “Winter conditions…
Structural complexity in forests improves carbon capture
By the National Science Foundation 10/9/2019 Forests in the eastern United States that are structurally complex — 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 the…
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…
Congressman John Yarmuth Selected as 2019 ESA Regional Policy Award Winner
ESA will present its 12th annual Regional Policy Award to Representative John Yarmuth, who represents Kentucky’s third congressional district in the U.S. House of Representatives, during the Society’s Annual Meeting in Louisville, Kentucky.
Traded forest tree seeds pose a great risk of introducing harmful pests, new research shows
By Center for Agriculture and Bioscience International 7/31/2019 CABI has led an international team of scientists who strongly suggest that the global trade of forest tree seeds is not as safe as previously believed, with insect pests and fungal pathogens posing a great risk to trees and forest ecosystems worldwide. Non-native insect pests and fungal pathogens present one of the…
Saving coral: New guidelines to protect and preserve Caribbean coral
By Ohio State University 7/25/2019 A consortium of coral experts today published new guidelines that could help corals in the Caribbean adapt to warmer, more acidic waters caused by climate change. The guidelines are the first of their kind to offer a definitive plan for collecting, raising and replanting corals in an attempt to maximize their chances for survival. The…
Trees suffered in drought-stricken African savanna
By Yale University 7/30/2019 Savannas cover about 40% of the area of the tropics, yet little is known about the effects of drought on their ecosystems. A new Yale-led study published in the journal Ecology shows that a severe drought between 2014 and 2016 in Kruger National Park in South Africa killed off a large number of trees, a finding that somewhat…
