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%.

DNA breakthrough detects genetic diversity of invasive fish

Ecologists have demonstrated that the genetic material that species shed into their environments can reveal not only the presence of the species but also a broad range of information about the genetics of whole populations — information that can help scientists trace the source of a new invasive population as well as prevent further invasion.

Scientists find good places to grow long-spined sea urchins, a starting point to restore ‘the lawn mowers of the reefs’

University of Florida scientists are trying to raise as many urchins as possible because they eat algae that could otherwise smother reef ecosystems and kill corals. A UF post-doctoral researcher led newly published research that identifies algae on which larval sea urchins grow into juveniles in a lab setting.

Out of the frying pan: Coyotes, bobcats move into human-inhabited areas to avoid apex predators — only to be killed by people

In Washington state, the presence of two apex predators — wolves and cougars — drives two mesopredator species — bobcats and coyotes — into areas with higher levels of human activity, with deadly results for the mesopredators.

Northern and southern resident orcas hunt differently, which may help explain the decline of southern orcas

In the Pacific Northwest and British Columbia, southern resident orcas have experienced no net population growth since the 1970s. But northern resident orcas, with a similar diet and territory, have grown steadily. A new study may help explain why: The two populations differ in how they hunt for salmon, their primary and preferred food source.

Grassroots Data Vital for Reducing Deadly Bird-Window Strikes

Much of the progress made in understanding the scope of bird deaths from building and window collisions has come as the result of citizen science, according to a newly published study. But the study also concludes that such grassroots efforts need more buy-in from government and industry, and better funding so they can keep a foot on the gas in their efforts to reduce bird-window collisions.

U.S. birds’ Eastern, Western behavior patterns are polar opposites

Avian functional diversity patterns in the Western U.S., where species and functional richness are both highest during the breeding season, are the polar opposite of what is seen in the East, where functional diversity is lowest when species richness is high, according to new research.

Human-wildlife conflicts rising worldwide with climate change

New research shows that a warming world is increasing human-wildlife conflicts globally: Climate shifts can drive conflicts by altering animal habitats, the timing of events, wildlife behaviors and resource availability. It also showed that people are changing their behaviors and locations in response to climate change in ways that increase conflicts.

FAU Harbor Branch Lands U.S. EPA Grant for ‘Hands-on’ Indian River Lagoon Field Trip

The project will host 125 field trips, which will educate as many as 3,125 socially disadvantaged middle and high school students about Florida’s natural resources and the importance of conserving them.

Corridors between Western U.S. national parks would greatly increase the persistence time of mammals

A new study analyzed the value of establishing ecological corridors for large mammals between Yellowstone and Glacier National Parks and between Mount Rainier and North Cascades National Parks. These corridors would enlarge populations and species to shift their geographic ranges more readily in response to climate change.

Years of monarch research shows how adding habitat will help conservation

A new peer-reviewed journal article provides an overview of Iowa State University research on the monarch butterfly, a synthesis of years of study that includes field observations, laboratory experiments and simulation modeling. The findings estimate that the state’s monarch conservation plan will increase the size of the monarch population by 10-25% per generation.

Hurricane’s effects killed sturgeon in Apalachicola River

As hurricane Michael churned through the Gulf of Mexico to make landfall near Florida’s Apalachicola River in 2018, it left a sea of destruction in its wake. The path was easy to follow on land, but debris and infrastructure failures also diminished the river’s water quality and led to the death of roughly half the gulf sturgeon population there.

Browse, graze, mate: Food and company help animals in captivity

From tongue rolling alpacas to irritable yaks and perturbed pigs, new research has lifted the lid on why some farm and zoo animals cope well with captivity and others display signs of stress.

Researchers from Aberystwyth and Portsmouth universities in the UK have published the first large-scale study to identify which species of hoofed animals, known as ungulates, are better suited to captive environments and which require better husbandry if kept in captivity.

Diverse landscapes at the heart of bee conservation

New research from the University of Georgia revealed that mixed land use – such as developments interspersed with forest patches – improves bee diversity and is leading to new solutions for bee conservation. The researchers hypothesized that development would negatively affect bee diversity, but the results of the study were surprising. They found that small amounts of development actually had a positive impact on the number of bee species present in a given area.

Virtual reality gives humans a turtle’s-eye view of wildlife

A virtual reality simulation designed by a University of Oregon professor could help spur people to environmental action. Participants in Project Shell don a virtual reality headset and take on the body of a loggerhead sea turtle, sporting flippers instead of arms. During a 15-minute immersive experience, they journey from a hatchling to an adult turtle, dodging hazards like ships and wayward fishing gear.
