By Montana State University 3/13/2019 As a college freshman, Alex Washburne already had his dream job: capturing lizards in the arid grasslands of New Mexico. He later went on to study snails, analyze stock prices for a hedge fund and collect scat for a major elk study around the Rockies. But it wasn’t until he crashed his rear-wheel drive truck…
By University of Wyoming 3/13/2019 Driven by the need for food, moose in western Wyoming are less likely to change their behavior to avoid wolves as winter progresses, according to new research by University of Wyoming scientists. The findings, published today (March 13) in the journal Ecology, provide new insights into the interactions of the region’s apex predators and their prey….
By San Diego State University 3/14/2019 California sheephead and spiny lobsters may be helping control sea urchin populations in Southern California kelp forests, where sea otters — a top urchin predator — have long been missing, according to a new San Diego State University (SDSU) study published in the journal Ecology. The research provides new insight into the complex predator-prey relationships…
By University of Freiburg 3/12/2019 The little owl, Athene noctua, is a small nocturnal owl and is classified as an endangered species on the German Red List. In recent years the existing population of little owls has successfully been stabilized in the south-west of Germany, and in some places numbers are even rising. In neighboring northern Switzerland on the other…
By Notre Dame 3/5/2019 In the United States, the Great Salt Lake in Utah is home to a multimillion dollar brine shrimp industry, which collects and sells the brine shrimp cysts, or eggs, as a food source for prawn farming around the world. However, the GSL and brine shrimp are also a key resource for waterbirds during migration and nesting….
Two Canadian biologists, including Dr. Troy McMullin of the Canadian Museum of Nature, are proposing a better way to assess the conservation value of old-growth forests in North America—using lichens, sensitive bioindicators of environmental change.
By University of Wyoming 3/5/2019 A rare plant found only at two sites in central Wyoming has persisted, in part, because it can recover from relatively low densities and grows at different rates within each location, according to new research led by a University of Wyoming scientist. The desert yellowhead, which grows on fewer than 55 acres in the Beaver…
By University College London 3/4/2019 Alien species are the main driver of recent extinctions in both animals and plants, according to a new study by UCL researchers. They found that since 1500, alien species have been solely responsible for 126 extinctions, 13% of the total number studied. Of 953 global extinctions, 300 happened in some part because of alien species,…
By Michigan State University 3/1/2019 African carnivores face numerous threats from humans. So, it’s a fair assumption that the presence of more humans automatically equates to decreases across the board for carnivores. New research led by Michigan State University and published in the current issue of Ecological Applications, however, shows that’s not always the case. The truth is some species…
By University of Göttingen 2/19/2019 Fairy circles are round gaps in arid grassland that are distributed very uniformly over the landscape and only occur along the Namib Desert in southern Africa and in parts of Australia. Various theories circulate about the actual cause of these unusual spatial patterns, ranging from poisonous Euphorbia plants or rising gases, to ants, termites or…
By Point Blue Conservation Science 2/21/2019 How wildlife respond to climate change is likely to be complex. To better understand the effects of climate change on the bird community in the Sierra Nevada region, new research published today from Point Blue Conservation Science examines the impacts to birds from a recent extreme drought (2013-2016). The drought resulted in the widespread…
By Princeton University 2/20/2019 Tokita, a graduate student in ecology and evolutionary biology (EEB), is partially funded by a fellowship from the National Science Foundation. He works with Corina Tarnita, an associate professor in EEB, to create computational models for how social groups — including ants and humans — develop properties like division of labor and social networks.

By UC Santa Cruz 2/13/2019 Sara Gonzalez, a Ph.D. student in ecology and evolutionary biology at UC Santa Cruz, is among the recipients of the Katherine S. McCarter Graduate Student Policy Awards from the Ecological Society of America (ESA). This award provides graduate students with the opportunity to receive policy and communication training in Washington, D.C., and meet with lawmakers….
By National Science Foundation 2/6/2019 Scientists find that decades of degradation created ‘resistant’ coral reefs Marine biologist Peter Edmunds was prepared for the worst. Back-to-back Category 5 hurricanes had torn through the Caribbean in September 2017. The scientist and his colleagues weren’t sure what they’d find when they visited fragile coral reefs near the island of St. John after the…
By THÜNEN INSTITUTE 2/4/2019 Sustainable exploitation of wild fish is possible, but only when fisheries policies are implemented that ensure precautionary catch regulations Due to overcapacities in fishing fleets and insufficiently regulated catches, many fish stocks in the Northeast-Atlantic had reached very low levels by the end of the 20th century. However, an increasing number of stocks has shown signs…
By The University of Oklahoma 2/6/2019 An OU team from the Geographical Ecology Group conducted 54 experiments in both grazed and ungrazed grasslands to determine the salt cravings of insects and the types of insects that crave salt. NORMAN–A University of Oklahoma team from the Geographical Ecology Group has published a new study in the journal Ecology on the nutritional preferences of…
By University of Tasmania 2/7/2019 Monitoring of sea urchins in Port Phillip Bay over a four-year period has revealed that booming urchin populations and the barren grounds they created by overgrazing kelp beds are likely to persist in the long term unless drastic action is taken. High-density populations of the Australian urchin Heliocidaris erythrogrammahave been monitored in Port Phillip Bay since…
By Deakin University 2/1/2019 Decades after their implementation, no-take marine reserves are coming up short in their ability to nurture the Great Barrier Reef’s shark populations back to natural levels, according to new research from a Deakin University ecologist. The research, published today in the journal Frontiers in Ecology and the Environment, found that after decades of protection, shark populations on the…
By Simon Fraser University 1/25/2019 A species of frog endemic to the Pacific Northwest faces a 50 per cent increase in the probability of extinction by the 2080s due to climate change, according to a new study published by SFU researchers. The mountain-dwelling Cascades frog thrives in extreme climatic conditions, ranging from dozens of feet of snow in winter to…
By Swansea University Prifysgol Abertawe 1/23/2019 A new study of Tasmanian devils has revealed that a transmissible cancer which has devastated devil populations in recent years is unlikely to cause extinction of the iconic species. New research led by Dr Konstans Wells from Swansea University has revealed that it is more likely that the disease will fade-out or that the devils will coexist…
