New study suggests culling animals who ‘don’t belong’ can be a flawed nature conservation practice

New research published today in the journal Science has concluded that eradicating animals on the basis that they are not native in order to protect plant species, can be a flawed practice costing millions of dollars, and resulting in the slaughter of millions of healthy wild animals.

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%.

Uncovering Camel Spiders’ Hidden Evolutionary Secrets with a Modern Genetic Tree

In a new study led by the laboratories of Prof. Prashant Sharma of the University of Wisconsin-Madison, and Dr. Efrat Gavish-Regev of the Hebrew University of Jerusalem, a team of researchers has uncovering the mysteries surrounding camel spiders (Solifugae), by successfully establishing the first-ever comprehensive molecular tree (phylogeny) of this enigmatic arachnid order.

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.

Wildlife experts investigate spread of ‘zombie deer disease’

A white-tailed deer afflicted with chronic wasting disease — also frequently referred to as “zombie deer disease” — will appear abnormally thin, move sluggishly, and salivate excessively. There is no cure: chronic wasting disease (CWD) is contagious and always fatal, and it has been detected with increasing frequency in Virginia and other states, raising concerns about effects on the deer population.

Hope for salamanders? Illinois study recalibrates climate change effects

For tiny salamanders squirming skin-to-soil, big-picture weather patterns may seem as far away as outer space. But for decades, scientists have mostly relied on free-air temperature data at large spatial scales to predict future salamander distributions under climate change. The outlook was dire for the mini ecosystem engineers, suggesting near elimination of habitat in crucial areas.

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.

Permanent daylight saving time would reduce deer-vehicle collisions, study shows

Adopting permanent DST in the United States would reduce deer-vehicle collisions and likely prevent an estimated 36,550 deer deaths, 33 human deaths, 2,054 human injuries and $1.19 billion in costs each year. Deer-vehicle collisions would decrease under permanent DST because skies would be brighter later in the evening

Artificial intelligence answers the call for quail information

When states want to gauge quail populations, the process can be grueling, time-consuming and expensive. It means spending hours in the field listening for calls. Or leaving a recording device in the field to catch what sounds are made—only to spend hours later listening to that audio. Then, repeating this process until there’s enough information to start making population estimates.
But a new model developed by researchers at the University of Georgia aims to streamline this process. By using artificial intelligence to analyze terabytes of recordings for quail calls, the process gives wildlife managers the ability to gather the data they need in a matter of minutes.

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.

WVU researchers come out of their shells to help at-risk turtles

Wood turtles, or Glyptemys insculpta, are North America’s only semi-aquatic primary terrestrial. Donald Brown, research assistant professor in West Virginia University’s Davis College of Agriculture, Natural Resources and Design, is leading a study that examines how oil and natural gas activity affects wood turtles.

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.
