Analysis: World’s Protected Areas Safeguard Only a Fraction of Wildlife

By Wildlife Conservation Society 6/5/2019 A new analysis published in the journal Frontiers in Ecology and the Environment shows that the world’s protected areas (PAs) are experiencing major shortfalls in staffing and resources and are therefore failing on a massive scale to safeguard wildlife. The analysis looked at more than 2,100 protected areas around the world and found that less than a…

An island haven for frogs

By Macquarie University 6/4/2019 New Guinea is one of the only places in the world where frogs are safe from the species-destroying chytrid fungus. An international team of scientists has published a new paper that shows how to keep it that way, but they need help to carry out their plan. The chytrid fungus has wiped out more than 90…

Researchers find seaweed helps trap carbon dioxide in sediment

By Florida State University 6/3/2019 Every beachgoer can spot seaweed in the ocean or piling up on the beach, but Florida State University researchers working with colleagues in the United Kingdom have found that these slimy macroalgae play an important role in permanently removing carbon dioxide from the atmosphere. Their work is published in the journal Ecological Monographs by the Ecological Society…

Thinning Forests, Prescribed Fire Before Drought Reduced Tree Loss

By UC Davis 5/29/2019 Thinning forests and conducting prescribed burns may help preserve trees in future droughts and bark beetle epidemics expected under climate change, suggests a study from the University of California, Davis. The study, published in the journal Ecological Applications, found that thinning and prescribed fire treatments reduced the number of trees that died during the bark beetle…

Every bat travels differently

By Max Planck Society 5/28/2019 The females of some bat species migrate hundreds of kilometres after hibernation to give birth to their offspring in insect-rich regions. Unlike birds, it is largely unknown how bats keep their energy consumption low during flight. Dina Dechmann and colleagues from the Max Planck Institute of Animal Behavior in Konstanz equipped female common noctule bats…

Lessons from the wild: slow but increasing long‐term growth allows for maximum longevity in European beech

By Gianluca Piovesan 5/28/2019 Beech trees older than 600 years discovered in the Pollino Massif: This high-mountain old-growth Mediterranean forest harbors the oldest deciduous hardwoods. Discovering, studying, and preserving old trees is a top priority for conservation biology and sustainable development. We used tree-ring data from a high-mountain old-growth Mediterranean beech forest to reconstruct long-term growth patterns in trees of…

Prescribed Burns Over the Long Haul: Ponderosa Pine Vegetation Resists Effects of Low-Severity Fire

By U.S. Forest Service – Pacific Northwest Research Station 5/23/2019 Prescribed burning is an important active management approach that can address the fuel buildup and wildfire hazards that currently face western forests after a century of fire exclusion and suppression. Although prescribed burns are applied widely across the United States, their effects aren’t always well-documented. That means managers can’t anticipate…

Lengthy Study Shows Value of Soil Health and Forest Restoration after Damaging Events

By UC Merced 5/23/2019 A nine-year experiment by a UC Merced Department of Life and Environmental Sciences professor and his colleagues is illuminating the importance of soil carbon in maintaining healthy and functioning ecosystems because of its influence on the microbial communities that live in soil. These communities’ health can help researchers understand the effects of climate change. Professor Stephen C….

Study finds link between backyard birds and tiger sharks

By Mississippi-Alabama Sea Grant Consortium 5/21/2019 A new study has found that songbirds are a remarkably common part of young tiger sharks’ diets. The study is described in the article “Tiger sharks eat songbirds: scavenging a windfall of nutrients from the sky,” which was published today in the peer-reviewed journal Ecology. Scientists investigated the stomach contents of 105 neonate (i.e. newborn) tiger sharks…
