Scientists issue plan for rewilding the American West
As the effects of climate change mount, ecosystem restoration in the US West has garnered significant public attention, bolstered by President Joe Biden’s America the Beautiful plan to conserve 30% of US land and water by 2030. Writing in BioScience, William J. Ripple and 19 colleagues follow up on the Biden plan with a proposal for a “Western Rewilding Network,” comprising 11 large reserve areas already owned by the federal government.
Pathogenic microbes in drying soils could present public health threat
Soil-borne pathogens are resilient to stressful conditions, and may be more likely than non-pathogenic microbes to survive the prolonged dry spells that are projected to persist regionally across many parts of the globe.
Nitrogen Footprint: Heavy Pollution and Resource Losses Due to Liquid Manure
Factory farming for meat production is harmful to the environment. In addition to its direct emissions of methane, its use of liquid manure releases climate-damaging nitrogen compounds such as ammonia and nitrous oxide into the atmosphere and pollutes the groundwater with nitrates. Researchers at the Karlsruhe Institute of Technology (KIT) have analyzed how the liquid manure produced by livestock farming, which is often used as fertilizer, affects its nitrogen footprint. They showed that the nitrogen pollution caused by liquid manure from the production of beef is three times higher than that for pork and eight times higher than that for poultry

Monarch butterfly populations are thriving in North America
For years, scientists have warned that monarch butterflies are dying off in droves because of diminishing winter colonies. But new research from the University of Georgia shows that the summer population of monarchs has remained relatively stable over the past 25 years.
Wildlife’s Worm-Wide Web
Many of us try to repress the thought of them, while others have come to accept them. Whatever your take on parasites is, they can tell scientists a lot about ecology, health and the environment.
The space between us
Tree beta diversity — a measure of site-to-site variation in the composition of species present within a given area — matters more for ecosystem functioning than other components of biodiversity at larger scales. The finding has implications for conservation planning.
Stress Among Wild Life
“I am stressed!” We have all said this sentence many times. Stress is a widespread phenomenon among humans.

Matt Ajemian, Ph.D., Receives Prestigious NSF CAREER Award
Matt Ajemian, Ph.D., has received a $1,103,081 NSF CAREER grant for a project that will build fundamental knowledge on where and when large shell-crushing predators feed in order to ensure a sustainable future for shellfish species. Further, the work can provide guidance to shellfish restoration programs that are currently “flying blind” with respect to predation risk.
A midge fly can be a source of currently used pesticides for birds, bats
Researchers reporting in ACS’ Environmental Science & Technology have observed that non-biting midge larvae accumulate contemporary pesticides from polluted water and retain the substances into adulthood. As a result, animals that eat the adult flies could consume small amounts of pesticides daily.
Evolution in Chicago’s clover: DePaul University researchers help chart global human impact on nature
Jalene LaMontagne, associate professor of ecology, and Windsor Aguirre, associate professor of evolutionary biology, are among hundreds of researchers who collected clover in 160 cities all over the world. The research, published this week in the journal “Science,” offers insight into how urbanization is transforming the genetic properties of plants and animals around us.
Revealing the ramifications of ocean acidification for coralline algae
Scientists have long suspected that coralline algae are particularly sensitive to changes in ocean chemistry. Now, researchers have found that most species of coralline algae studied are negatively affected by ocean acidification.
After California’s 3rd-largest wildfire, deer returned home while trees were ‘still smoldering’
While many animals have adapted to live with wildfires of the past — which were smaller, more frequent and kept ecosystems in balance across the West — it’s unclear to scientists how animals are coping with today’s unprecedented megafires. A team of researchers tracked a population of black-tailed deer before, during and after the 2018 Mendocino Complex Fire and found that most of the deer returned home within hours of the fire, while trees were still smoldering.
Carnivores may adjust schedule to avoid each other, researchers find
Just as humans may leave their home five minutes early to avoid a talkative neighbor or depart work late to avoid a rude coworker, carnivorous mammals may go out of their way to avoid other species.

Microorganisms, plants, and animals accomplish great feats every day. For example, by decomposing material, producing plant biomass, or pollinating flowers, they keep nature ‘up and running,’ thereby securing the livelihood of humans.
Bat guts become less healthy through diet of ‘fast food’ from banana plantations
Nectar-feeding bats foraging in intensively managed banana plantations in Costa Rica have a less diverse set of gut microbes in comparison to bats feeding in their natural forest habitat or organic plantations, reveals new research published today in Frontiers in Ecology and Evolution.
Genotyping Reveals Significance of Mesophotic Reefs for Florida Keys’ Coral Recovery
Researchers are the first to compare the genetic structure and genomic diversity of paired shallow and upper mesophotic coral sites in the Northern and Southern Dry Tortugas and the Lower and Upper Florida Keys. Results suggest that while vertical connectivity between paired shallow and mesophotic populations can vary, certain mesophotic coral populations are important for maintaining the long-term survival of this ecologically important coral species throughout the Florida Keys and should be considered in future management strategies.

Nestled at the intersection of eastern Tennessee’s Anderson and Roane Counties, the Oak Ridge National Environmental Research Park is a living laboratory and a major resource for conducting ecological studies.
Behold the humble water flea, locked in a battle of mythological proportions
In Greek mythology, Hydra was a monstrous water serpent that lived in a swamp and terrorized nearby residents. When intrepid Hercules sliced off one of Hydra’s multiple heads, two more heads grew back in its place. This counterintuitive result — when an action taken to reduce a problem actually multiplies it — is known as a hydra effect.

Urbanization is one of the most drastic forms of land-use change, and its negative consequences on biodiversity have been studied extensively in temperate countries such as Germany.
Food claiming to have ‘wild mushrooms’ rarely does
Harvesting wild mushrooms requires an expert eye, making products containing wild fungi expensive. Due to minimal food regulations, it’s nearly impossible to know what species are actually contained within. Sequencing revealed food products labeled with wild mushrooms mostly contained cultivated fungi and some mushrooms poisonous to humans.
Two-pronged integrative approach developed by NUS biologists increases accuracy of mosquito vector surveillance
A team of NUS researchers has developed an integrative approach that increases the accuracy of mosquito surveillance and management. The two-pronged strategy boosts accuracy in sampling by including mosquito larvae, and species identification using short DNA sequences.
Mountain lions moved less, downsized territory during LA’s pandemic shutdown
As people sheltered in place at the onset of the COVID-19 pandemic, sightings of wildlife in urban areas helped spawn a meme, “Nature is healing,” that reflected an intuitive belief: Carnivores were stretching their legs, and their ranges, by expanding into long-lost territory.
Low-cost 3D Method Rapidly Measures Disease Impacts on Florida’s Coral Reefs
A low-cost and rapid 3D technique is helping scientists to gain insight into the colony- and community-level dynamics of the poorly understood stony coral tissue loss disease responsible for widespread coral death throughout the Tropical Western Atlantic. They adapted Structure-from-Motion (SfM) photogrammetry to generate 3D models for tracking lesion progression and impacts on diseased coral colonies. They combined traditional diver surveys with 3D colony fate-tracking to determine the impacts of disease on coral colonies throughout Southeast Florida.
