In the journal Science, some of the world's foremost biodiversity experts from DIVERSITAS, led by Arizona State University scientist Charles Perrings, offer a strategic approach to the 2020 targets being considered at the Convention on Biological Diversity in Nagoya, Japan, on Oct. 18-29. An approach that incorporates trade-offs, timing and complexity.
Whale feces float--and strongly enhance productivity of fisheries, scientists at the University of Vermont and Harvard have found, reversing the assumption that whales accelerate loss of nutrients to the bottom. This nitrogen input in the Gulf of Maine is more than the input of all rivers combined, 23,000 metric tons annually.
Contrary to some previous, highly publicized, reports, ocean acidification is not likely to worsen the hearing of whales and other animals, according to a Woods Hole Oceanographic Institution (WHOI) scientist who studies sound propagation in the ocean.
Researchers may have a greater understanding of the mysterious colony collapse disorder.
Study of ocean migration indicates that local management of the population may be insufficient and supports recently proposed listing for Atlantic sturgeon under U.S. Endangered Species Act
A UNH professor of biochemistry and her colleagues have identified the first reproductive hormone of the hagfish – a gonadatropin -- representing a significant step toward unraveling the mystery of hagfish reproduction. At 500 million years old, hagfish are the oldest living vertebrate, predating the dinosaurs.
Ambitious plans to expand acreage of bioenergy crops could have a major impact on birds in the Upper Midwest, according to a study published today (Oct. 4) in the online edition of the Proceedings of the National Academy of Sciences.
A new Baylor University study has identified several key physical, chemical and biological factors that influence the success of blue catfish populations in Texas reservoirs. The study was completed in collaboration with the Texas Parks and Wildlife Department and is the largest and most comprehensive study ever done exploring catfish survivability in Texas.
Reefs of deep-sea corals are discovered for the first time in the Mediterranean, offshore of Israel, by the "Nautilus" cruise. "It's like finding a flourishing oasis in the middle of the desert," said Dr. Yizhaq Makovsky.
An NC State researcher is part of a team that has discovered fossilized feathers from a giant penguin that lived near the Equator more than 36 million years ago. These fossils reveal color patterns in an ancient extinct penguin species, and offer clues about modern penguins' evolution.
Typically, monkeys don’t know what to make of a mirror. They may ignore it or interpret their reflection as another, invading monkey, but they don’t recognize the reflection as their own image. Chimpanzees and people pass this “mark” test — they obviously recognize their own reflection and make funny faces, look at a temporary mark that the scientists have placed on their face or wonder how they got so old and grey.
The world’s rivers, the single largest renewable water resource for humans and a crucible of aquatic biodiversity, are in a crisis of ominous proportions, according to a new global analysis.
A Wildlife Conservation Society (WCS) study on nesting birds in Argentina finds that increasing temperatures and rainfall—both side effects of climate change in some parts of the world—could be bad for birds of South America, but great for some of their parasites which thrive in warmer and wetter conditions.
When honeybees seek a new home, they choose the best site through a democratic process that humans would do well to emulate, according to Thomas Seeley, a professor of neurobiology and behavior at Cornell University, in his new book, “Honeybee Democracy."
While birds living in urban areas face more predators than do those in rural areas, that doesn’t mean urban birds face more danger from nest robbers.
Craig Altier, a member of the Food and Drug Administration’s Veterinary Medicine Advisory Committee and an associate professor at the College of Veterinary Medicine at Cornell University, comments on potential FDA approval of the first genetically engineered animal for use as food.
A 50 million old snake undergoes a CT scan at The Methodist Hospital in Houston. Paleontologist Hussam Zaher from Brazil wants to determine where the snake fits in to the evolution of snakes in North America.
A newly discovered skeleton of an ancient seabird from northern Chile provides evidence that giant birds were soaring the skies there 5-10 million years ago. The wing bones of the animal exceed those of all other birds in length; its wingspan would have been at least 5.2 m (17 ft.). This is the largest safely established wingspan for a bird.
A new peer-reviewed paper by the Wildlife Conservation Society and other groups reveals an ominous finding: most of the world’s last remaining tigers—long decimated by overhunting, logging, and wildlife trade—are now clustered in just six percent of their available habitat.
The only things certain in life are death and taxes, the saying goes. The corollary could be that the only things ranchers can depend on to be uncertain are weather and prices. These uncertainties are the major risks for rangeland livestock producers in maintaining a profitable operation. Climate variations can bring about fluctuations in forage production that impact grazing and herd sustainability.
