UrduA unique long-term study quantified the abundance of whitespotted eagle and giant manta rays in Southeast Florida. Researchers conducted 120 survey flights between 2014 and 2021 from Miami north to the Jupiter Inlet. One or both species were seen on nearly every flight and both populations appear to be stable in the region. The giant manta rays were more abundant in the south and the whitespotted eagle rays were found all along the coast. Neither species seems to be deterred by the greater human population density in Fort Lauderdale/ Miami.

Spatial model predicts bumblebee exposure to pesticide use
It has long been known that agricultural pesticides are one of the greatest threats to bees and other essential pollinators.
Study: Wild pig populations in U.S. can be managed
Recent conservation efforts have proven effective at controlling wild pig populations in the Southeastern United States, according to new research from the University of Georgia’s Savannah River Ecology Laboratory and Warnell School of Forestry and Natural Resources. Within 24 months of the start of control efforts in the study area located around the Savannah River Site in Aiken, South Carolina, researchers found a reduction of about 70% in relative abundance of pigs and a corresponding decline in environmental rooting damage of about 99%.
Bats struggle during organic farming transition
Bat activity falls as farms make the transition to organic agriculture, new research shows.
Wildlife crossing guards
Oak Ridge National Laboratory researchers developed a model framework that identifies ways to ensure wildlife can safely navigate their habitats while not unduly affecting infrastructure.
Skin disease in endangered killer whales concerns scientists
Scientists studying endangered southern resident killer whales have observed a strong increase in the prevalence of skin disease in this population.
Study finds human impact on wildlife even in protected areas
By 2030, if the 30 by 30 initiative supported by more than 100 countries is successful, 30% of our land and ocean ecosystems will be designated protected areas meant to safeguard biodiversity and help limit the impacts of climate change.
Lynx reintroduction in Scotland? It’s complicated
Plans to reintroduce the lynx in Scotland provoke a complex range of opinions, new research shows.
Glacier National Park could provide climate haven for Canada Lynx
Glacier National Park is home to around 50 Canada lynx, more than expected, surprising scientists who recently conducted the first parkwide occupancy survey for the North American cat.
Short-term bang of fireworks has long-term impact on wildlife: Study
Popular fireworks should be replaced with cleaner drone and laser light shows to avoid the “highly damaging” impact on wildlife, domestic pets and the broader environment, new Curtin-led research has found.

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.
How Will Climate Change Affect the Geographic Range of Salamander Species in the U.S. And Canada?
In a study published in the Journal of Wildlife Management, investigators predicted the geographic range restriction of several different species of salamanders in eastern Canada and the United States under future climate scenarios in 2050 and 2070.
Ecosystems worldwide are disrupted by lack of large wild herbivores – except in Africa
June 2021 saw the start of the United Nations Decade on Ecosystem Restoration. A total of 115 countries have committed themselves to restoring up to a billion hectares of nature worldwide.
Ancient oyster shells provide historical insights
Scientists studying thousands of oyster shells along the Georgia coast, some as old as 4,500 years, have published new insights into how Native Americans sustained oyster harvests for thousands of years, observations that may lead to better management practices of oyster reefs today.
