In the bone-dry desert, a truly remarkable, newfound microbial species manages to eke out a living drinking the meager moisture that condenses from the air onto spiderwebs.
Elevated concentrations of nitrogen and phosphorus, nutrients that can negatively impact aquatic ecosystems and human health, have remained the same or increased in many streams and aquifers across the Nation since the early 1990’s, according to a new national study by the U.S. Geological Survey.
More than 60 organizations in 27 states are asking the Environmental Protection Agency to ban toxic lead in bullets and shotgun pellets used for hunting and in fishing lures and sinkers. The Center for Biological Diversity, American Bird Conservancy and a coalition of conservation, hunting and veterinary groups petitioned EPA in early August for the ban on lead, a substance that needlessly kills and harms millions of wild birds and other animals every year and endangers public health. Since the [...]
In yet another important ivory seizure at Suvarnabhumi International Airport this year, Customs officers have apprehended 90 kilogrammes of ivory from a passenger attempting to smuggle it into the country packed inside four large pieces of luggage.
For marine iguanas living in the Galapagos Islands, an El Niño can be deadly. Some die from starvation while others survive. Scientists have long believed that the difference between life and death for the iguana depended on the animals’ ability to secrete the stress hormone corticosterone.
Jaguars versus cattle is an age-old conflict for people living on the Brazilian plains. South America’s Pantanal region is important to the continued survival of jaguars, but it also has been home to cattle ranching for more than 200 years. New insights into this conflict are offered through a study using global positioning system (GPS) technology to track the predatory patterns of these jaguars, recording what animals they kill and how often.
The Weddell seal is one of the deepest diving seals on earth and can hold its breath underwater for up to 90 minutes in their native habitat of Antarctica. Scientists have just begun to unravel what physiological characteristics in the seals’ swimming muscles allow them to dive so deep and for so long. But now, new research from Baylor University biologists has found that there is a switching of fuel usage as this animal goes from a non-diving pup to [...]
Sometime in the last 30,000 years or so, two separate bat species colonized the Caribbean and converged on islands in the southern Lesser Antilles. One came from Mexico while the other traveled from northern South America.
The Giant Armadillo, Priodontes maximus, is listed as ‘Vulnerable’ on the IUCN Red List of Threatened Species™. It is the largest living armadillo species, and occurs east of the Andes in South America, from northern Venezuela and the Guianas south to Paraguay, southern Brazil and northern Argentina. Although still widespread, the Giant Armadillo is patchily distributed and locally rare, and its population is undergoing a decline. The main threat to the species is hunting for its meat, which is compounded [...]
