It’s a jungle out there in the suburbs, where many wild mammals are thriving near humans. That’s the conclusion of alarge-scale study using camera trap images from hundreds of citizen scientists in Washington, D.C., and Raleigh, North Carolina.(more…)
Long free of humans, the site of a nuclear disaster may play an important role in wildlife conservation in the region.
COLUMBIA, Mo. – The Chernobyl Exclusion Zone (CEZ) is a 1,660 square mile area surrounding the remains of the Chernobyl Nuclear Power Plant, which exploded on April 25, 1986, and released large amounts of radiation into the area. Living in the zone remains prohibited 32 years later, and the resulting lack of human presence has led some to call the zone ade-facto nature reserve. (more…)
Bird populations across Europe have experienced sharp declines over the past 30 years, with the majority of losses from the most common species, say researchers from the University of Exeter, the RSPB and the Pan-European Common Bird Monitoring Scheme (PECBMS) in a new study. However numbers of some less common birds have risen.
The study, published in the journal Ecology Letters, reveals a decrease of 421 million individual birds over 30 years. Around 90 percent of these losses were from the 36 most common and widespread species, including house sparrows, skylarks, grey partridges and starlings, highlighting the need for greater efforts to halt the continent-wide declines of our most familiar countryside birds.

ANCHORAGE — Nearly 25 years after the Exxon Valdez oil spill injured wildlife off the coast of Alaska, a new report issued today by the U.S. Geological Survey indicates that sea otters have returned to pre-spill numbers within the most heavily oiled areas of Prince William Sound.
Sea otters in the path of the oil incurred heavy mortality when 42 million liters of Prudhoe Bay crude oil were spilled in Prince William Sound in March 1989, with an estimated loss of several thousand otters. Through long-term data collection and analysis, scientists found that sea otters were slow to recover, likely because of chronic exposure to lingering oil. Other studies documented persistence of oil in the sea otter’s intertidal feeding habitats. (more…)
UA undergraduate researcher Robert Clark, his public health mentor and Pima County officials collaborated on an investigation of rabies cases in Pima County.
In a volunteer opportunity turned research project, University of Arizona undergraduate researcher Robert Clark has developed a comprehensive, multi-year snapshot of animal cases of rabies in Pima County.
Hydraulic fracturing fluids are believed to be the cause of the widespread death or distress of aquatic species in Kentucky’s Acorn Fork, after spilling from nearby natural gas well sites. These findings are the result of a joint study by the U.S. Geological Survey and the U.S. Fish and Wildlife Service.
The Acorn Fork, a small Appalachian creek, is habitat for the federally threatened Blackside dace, a small colorful minnow. The Acorn Fork is designated by Kentucky as an Outstanding State Resource Waters. (more…)
LARAMIE, Wyo. — Migratory elk are coming back from Yellowstone National Park with fewer calves due to drought and increased numbers of big predators – two landscape-level changes that are reducing the benefits of migration with broader implications for conservation of migratory animals, according to a new study published in the journal Ecology.
The new study by the Wyoming Cooperative Fish and Wildlife Research Unit – a joint program involving U.S. Geological Survey, the University of Wyoming, and the Wyoming Game and Fish Department, describes a long-term decline in the number of calves produced annually by the Clarks Fork herd, a population of about 4000 elk whose migrants travel annually between winter ranges near Cody, Wyoming and summer ranges within Yellowstone National Park. Migratory elk experienced a 19 percent depression in rates of pregnancy over the four years of the study and a 70 percent decline in calf production over 21 years of monitoring by the WGFD, while the elk that did not migrate, known as resident elk, in the same herd experienced high pregnancy and calf production and are expanding their numbers and range into private lands outside of the park.

Oculoplastic surgeons at the Yale Eye Center perform a range of procedures, from Botox injections to fix wrinkles, to lifesaving surgeries to help treat cancers near the eye.
(March 2013) Gail Chiasson’s “puffy eyelids” had gotten so heavy she felt as if they’d become permanently half-shut. Not only did she look sleepy, she felt sleepy. She couldn’t read a book for long and grew especially concerned when a doctor trying to perform an eye test had to tape her lids out of the way.
She visited the Yale Eye Center, where a surgeon performed a blepharoplasty, a surgical procedure to lift the upper eyelids and improve vision. He also removed extra fat from her lower lids to improve her appearance. The results, says Chiasson, are “unbelievable, like night and day, from being sleepy to wide awake. I didn’t even realize how much the droopy lids had affected my peripheral vision.” (more…)
