Businesses Can Help Preserve Endangered Species, Improve Employee Morale With Small Landscape Changes

COLUMBIA, Mo.—Raptors, or birds of prey, some of which are endangered species, typically live in environments that provide natural land cover, such as forests and grasslands. Protecting endangered raptor species helps maintain food chain balance and prevents overpopulation of common raptor prey, such as snakes and rodents. As more businesses are built on the edges of urban areas, land where raptors once lived becomes industrialized, which raises concerns about the consequences of habitat destruction on raptor populations. Now, University of Missouri researchers have found that businesses can contribute to raptor preservation efforts by engaging in less development of lawn areas and increased planting or preservation of native grasslands and woodlots.

Herbivores Dine on Toxic Plants, Thanks to Gut Microbes

Woodrats lost their ability to eat toxic creosote bushes after antibiotics killed their gut microbes. Woodrats that never ate the plants were able to do so after receiving fecal transplants with microbes from creosote-eaters, University of Utah biologists found. (more…)

Is Self-Fumigation for the Birds?

Save Threatened Species by Giving Them Treated Cotton for Nests

When University of Utah biologists set out cotton balls treated with a mild pesticide, wild finches in the Galapagos Islands used the cotton to help build their nests, killing parasitic fly maggots to protect baby birds. The researchers say the self-fumigation method may help endangered birds and even some mammals.

“We are trying to help birds help themselves,” says biology professor Dale Clayton, senior author of a study outlining the new technique. The findings were published online May 5, 2014, in the journal Current Biology. (more…)

New book explores ‘frontier’ metaphor in science

Leah Ceccarelli is a professor of communication and author of the book “On the Frontier of Science: An American Rhetoric of Exploration and Exploitation.” She answered a few questions about the book for UW Today.

Q: What’s the concept behind this book? Why did you write it?

A: I kept seeing appeals to the American frontier spirit in the public arguments of scientists. That rhetoric was often inspiring, giving scientists an exciting image of their work across the metaphorical “boundaries” of knowledge. But it was also troubling in the expectations it set out about the manifest destiny of scientists to push forward at all costs, and in the way it reinforced their separation from a public that funds their endeavors.

Scientists Use Marine Robots to Detect Endangered Whales

Two robots equipped with instruments designed to “listen” for the calls of baleen whales detected nine endangered North Atlantic right whales in the Gulf of Maine last month. The robots reported the detections to shore-based researchers within hours of hearing the whales (i.e., in real time), demonstrating a new and powerful tool for managing interactions between whales and human activities.

The team of researchers, led by Woods Hole Oceanographic Institution (WHOI) scientists Mark Baumgartner and Dave Fratantoni, reported their sightings to NOAA, the federal agency responsible for enforcing the Marine Mammal Protection Act. NOAA Fisheries Service, in turn, put in place on Dec. 5 a “dynamic management area,” asking mariners to voluntarily slow their vessel speed to avoid striking the animals. (more…)

Collaring Tapirs – Elephant look-alikes – to Help Them Survive

EAST LANSING, Mich. — A team of Michigan State University researchers will soon be heading into the rainforests of Nicaragua to help an endangered species known as a Baird’s tapir co-exist with local farmers whose crops are being threatened by the animals.

The animals were thought to be extinct in that part of the world until just two years ago when the MSU team discovered them still living there through the use of “camera trapping” – the setting up of still and video cameras in order to “capture” the animal. (more…)

American Eels Return to Mountain Streams after Dam Removal

Shenandoah National Park, Va. – American eels are declining across their range but are showing indications of a population revival following the removal of a large dam in Virginia.

The removal of Embrey Dam on the Rappahannock River increased American eel numbers in headwater streams nearly 100 miles away, according to research just published by U.S. Geological Survey, U.S. Fish and Wildlife Service, and National Park Service researchers.

American eels undergo long-distance migrations from their ocean spawning grounds in the Sargasso Sea to freshwater streams along the Atlantic coast from northern South America to Greenland. Dams may slow or even stop upstream eel migrations. However, prior to this research, little was known about American eel responses to dam removal. (more…)

New Findings of Endangered Birds at Hakalau Forest National Wildlife Refuge Give Hope to Recovery Efforts

HAWAI’I ISLAND, Hawai‘’— Three of Hawai’i Island’s rarest endangered forest birds have been detected at lower elevations of Hakalau Forest National Wildlife Refuge for the first time in 30 years.

The rediscovery of the three endangered species at lower elevations than expected was part of a joint U.S. Fish and Wildlife Service and U.S. Geological Survey project on the potential impact of climate change on avian disease. All three species are believed to be highly susceptible to mosquito-transmitted diseases, limiting their distribution to the cooler, higher elevations of the refuge. These new observations significantly extend the current known range of these species at the refuge. (more…)
