By The Swedish University of Agricultural Sciences 1/23/2020 While some trends suggest that insect abundances generally decrease, there is also a fear that problems with pest insects will increase in the future. The logic is simple – insects are ectothermic and should thereby be favored by ongoing climate warming. It is however not that easy to predict future damage of pest…
By The U.S. Geological Survey 1/23/2020 (Carlisle, Pa.) – Researchers from Dickinson College and the U.S. Geological Survey collaborated on field research to understand the ability of human searchers to detect the invasive brown treesnake (BTS) on the island of Guam. Due to their nocturnal and tree-dwelling habits, these snakes are extremely difficult to detect, especially when they are present…
By University of Michigan 1/23/2020 ANN ARBOR—While conducting fieldwork in Puerto Rico’s central mountainous region in 2016, University of Michigan ecologists noticed tiny trails of bright orange snail excrement on the undersurface of coffee leaves afflicted with coffee leaf rust, the crop’s most economically important pest. Intrigued, they conducted field observations and laboratory experiments over the next several years and…
By UC Santa Barbara 1/29/2020 Anyone who’s read “The Lorax” will recognize that certain species serve as the foundation of their ecosystems. When the truffula trees disappear, so to do the swomee-swans and bar-ba-loots. However, the same is not necessarily true the other way around. Scientists have taken a growing interest in ecological stability — the factors that make an…
By UC San Diego 1/23/2020 Four hours east of Medellín in northern Colombia’s Puerto Triunfo municipality, the sprawling hacienda constructed by infamous drug lord Pablo Escobar of “Narcos” fame has become a tourist attraction. When Escobar’s empire crashed, the exotic animals housed at his family’s zoo, including rhinos, giraffes and zebras, were safely relocated to new homes… except for the…
By Pennsylvania State University 1/8/2020 Selective fishing can disrupt the delicate balance maintained between corals and algae in embattled Caribbean coral reefs. Removing large parrotfish, which graze on algae like large land mammals graze on grasses, can allow the algae to overtake the corals, with potentially dire consequences for reef health. New experimental research suggests that maintaining a healthy size…
By University of Georgia 1/6/2020 Nearly a decade after the nuclear accident in Fukushima, Japan, researchers from the University of Georgia have found that wildlife populations are abundant in areas void of human life. The camera study, published in the Journal of Frontiers in Ecology and the Environment, reports that over 267,000 wildlife photos recorded more than 20 species, including wild…
By Lancaster University 12/20/2019 The regrowth of Amazonian forests following deforestation can happen much slower than previously thought, a new study shows. The findings could have significant impacts for climate change predictions as the ability of secondary forests to soak up carbon from the atmosphere may have been over-estimated. The study, which monitored forest regrowth over two decades, shows that…
By Oregon State University 12/9/2019 CORVALLIS, Ore. – A study by Oregon State University researchers has identified forests in the western United States that should be preserved for their potential to mitigate climate change through carbon sequestration, as well as to enhance biodiversity. Those forests are mainly along the Pacific coast and in the Cascade Range, with pockets of them…
By Chrystian Trejedor, Florida International University 12/18/2019 The north might no longer be as inhospitable to mangroves as it once was. Fleeing rising seas in South Florida, mangroves are establishing themselves farther north along Florida’s Atlantic and Gulf coasts. Some are thriving in southern Texas and are already approaching Mississippi and Alabama – places where they historically could not withstand the climate,…
By Steve Lundeberg, Oregon State University 12/9/2019 CORVALLIS, Ore. – A study by Oregon State University researchers has identified forests in the western United States that should be preserved for their potential to mitigate climate change through carbon sequestration, as well as to enhance biodiversity. Those forests are mainly along the Pacific coast and in the Cascade Range, with pockets…
By Anglia Ruskin University 12/11/2019 CAMBRIDGE, U.K.–Findings from ARU project could help to protect solitary, ground-nesting bees The UK’s first citizen science project focusing on solitary, ground-nesting bees has revealed that they nest in a far broader range of habitats than previously thought. There are approximately 250 species of solitary bee in the UK, but far less is known about…
By University of Manitoba 12/12/2019 MANITOBA, Canada – University of Manitoba researchers made a recent discovery that suggests Purple Martins, unlike other long-distance migratory songbirds, show promise of being able to adapt to climate change. The Purple Martin’s (Progne subis) breeding range spans from Florida to northern Alberta, and the smartphone-sized songbird passes our winter months on small islands in…
By Washington State University 12/4/2019 PULLMAN, Wash. – Resembling an overgrown house cat with black-tipped ears and a stubby tail, the Canada lynx, a native of North America, teeters on the brink of extinction in the U.S. The few lynx that now roam parts of Washington and the mountainous Northwest survive largely because of a network of protected landscapes that crosses…
By KU Leuven 11/20/2019 Researchers from KU Leuven have discovered that the presence of yeasts can alter the chemical composition and thus the nutritional value of nectar for pollinators such as bees. The study discovered that yeasts can even boost bee health and colony fitness. “Research into the role of microbes in our ecosystem is of vital importance to safeguard bees.”…
By Colorado State University 11/15/2019 Dennis Ojima is the latest member of the Colorado State University faculty to be selected by members of the Ecological Society of America to serve as president-elect. His term begins in 2020. “For more than 30 thirty years, Dennis Ojima has been at the forefront of the field of ecology and has had an immeasurable impact…
By Cornell University 11/20/2019 ITHACA, N.Y. -Metal copper from agricultural runoff and marine paint leaching from boat hulls poses an emerging threat to soft coral sea fans in the waters around Puerto Rico. In a Cornell-led study, published in the journal Ecological Applications, scientists report evidence of metal pollution creating danger for the soft coral sea fans. “We know warming oceans…
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….
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…
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…
