Disappearing arctic lakes linked to climate change
Continued arctic warming may be causing a decrease in the number and size of Arctic lakes. The issue is the subject of a paper published in the June 3 issue of the journal "Science." The paper, titled, "Disappearing Arctic Lakes" is the result of a comparison of satellite data taken of Siberia in the early 1970s to data from 1997-2004. Researchers, including Larry Hinzman with the Water and Envir...Wild bees and the flowers they pollinate are disappearing together
The diversity of bees and of the flowers they pollinate, has declined significantly in Britain and the Netherlands over the last 25 years according to research led by the University of Leeds and published in Science this Friday (21 July 2006). The paper is the first evidence of a widespread decline in bee diversity. Concerns have been raised for years about the loss of pollination service...Himalayan forests disappearing
Studies in which monkeys were asked to manipulate computer cursors for fruit juice rewards have revealed that the brain's "executive" center plans behaviors not by specifying movements required for given actions, but rather the events that will result from those actions. The distinction is significant, said the researchers, because it yields new basic insight into a central function of beh...Disappearing nest egg: Researcher studying declining numbers of macaws
One of the most colorful birds in the world may have a less-than-colorful future. Macaws, the largest members of the parrot family, have seen their numbers decline in recent decades, and that trend is continuing today. Dr. Don Brightsmith, a bird specialist at Texas A&M University's Schubot Exotic Bird Center, part of the College of Veterinary Medicine & Biomedical Sciences, is s...Over a century after disappearing, wild elk return to Ontario
After disappearing from Ontario due to over hunting in the 19th century, wild elk have returned to the province thanks to the efforts of the Ontario elk restoration program. According to a report on the program’s success, published in the March issue of Restoration Ecology, 460 elk were brought from Alberta and released in various Ontario sites between 1998 and 2001. "The Ontario elk resto...
