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…

Baby tiger sharks eat songbirds

By Field Museum 5/21/2019 Tiger sharks have a reputation for being the “garbage cans of the sea”—they’ll eat just about anything, from dolphins and sea turtles to rubber tires. But before these top predators grow to their adult size of 15 feet, young tiger sharks have an even more unusual diet. Scientists have just announced in a new paper in…

Intensive silviculture accelerates Atlantic Rainforest biodiversity regeneration

By São Paulo Research Foundation (FAPESP) 5/22/2019 An experiment conducted in Brazil in an area of Atlantic Rainforest suggests that intensive silviculture, including the use of herbicide and substantial amounts of fertilizer, is a more effective approach to promoting the regeneration of tropical forest and biomass gain than the traditional method based on manual weeding and less fertilizer. The study…

Temperatures in the African savanna affect ant/plant mutualism

By University of Florida 5/16/19 In the wide world of tropical flora, insects often take up the mantle of protecting the plants that shelter them, each mutually satisfied in a happy marriage of nature’s making. This is particularly true for acacia trees that tower over the African savanna. Their tiny protectors are carnivorous ants that dissuade animals from browsing on…
