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.

Fecal Transplants Let Packrats Eat Poison

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…)

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.

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…)

The Giant Panda: The Good News

Finally some good news on the environment, on ecology and on the Giant Panda: a revolutionary new technique developed by the PR China’s Chengdu breeding center seems certain to assure that greater numbers of this endangered species can be raised in thereby save it from extinction.

Just 1,600 Giant Pandas live in the wild, in 40 government-controlled panda reserves in the People’s Republic of China. The new breeding program has raised the number of animals bred in captivity to 300, while just this year 19 cubs have been born after artificial insemination programs in China’s two main breeding centers.

Breeding Giant Pandas in captivity is no easy task. They have the strangest gestation period which can range from eleven weeks to eleven months, they appear not to be sexually aroused by being held in captivity, females are on heat for 72 hours a year and are fertile during a 12 to 24-hour window inside that period. The small size of the male penis also means the mating position has to be exactly right, and this is not always possible in captivity. (more…)
