The impact fish stocking has on aquatic insects in mountain lakes can be rapidly reversed by removing non-native trout, according to a study completed by U.S. Forest Service and University of California, Davis, scientists. Their findings appear in a current online issue of the journal Freshwater Biology where they describe experiments that examined some effects [...]

1 moose, 2 moose: Scientist seeks correction in number of species
FAIRBANKS, Alaska—It is a misinterpretation of the application of the bedrock of scientific naming with regard to the number of moose species that Kris Hundertmark, a University of Alaska Fairbanks wildlife geneticist at the Institute of Arctic Biology, seeks to correct. The adoption of Carl Linnaeus’ two-part, genus-species system of naming, called taxonomy, has been [...]

PHILADELPHIA –- A team of biologists at the University of Pennsylvania has completed a research study begun in 1915 and determined that a snail making its home in the northwest Atlantic Ocean around Mount Desert Island, Me., has experienced a dramatic increase in the size of its shell during less than a century, providing a [...]
Atlantic snails are increasing dramatically in size, Queen’s researcher discovers

Fisher A Queen’s University biologist has discovered that the shell lengths of snails in the northwest Atlantic Ocean – an important member of the Atlantic food chain – have increased by 22.6 per cent over the past century. Until now, this [...]
Hurdia victoria was originally described in 1912 as a crustacean-like animal. Now, researchers from Uppsala University and colleagues reveal it to be just one part of a complex and remarkable new animal that has an important story to tell about the origin of the largest group of living animals, the arthropods. The findings are being [...]
Two juvenile skeletons of the ostrich-mimic dinosaur Sinornithomimus died when they were a little over one year in age. In their ribcages are stomach stones and the carbonized remains of their last plants they consumed. (cast)-(Mike Hettwer, Project Exploration) . Photo credit: The University of Chicago.

New finds of 95 million year old fossils reveal much earlier origins of modern octopuses. These are among the rarest and unlikeliest of fossils. The chances of an octopus corpse surviving long enough to be fossilized are so small that prior to this discovery only a single fossil species was known, and from fewer specimens [...]
Try this at home: If fruit flies are buzzing around your kitchen, switch on your hairdryer and aim it at the flies. A gentle stream of air will stop them in their tracks, putting them in prime position for swatting. The reaction of fruit flies to wind was something that had intrigued biologist David J. [...]
Elephant shark genome sequence leads to discovery of color perception in deep-sea fish
posted in Animals, SMThe elephant shark, a primitive deep-sea fish that belongs to the oldest living family of jawed vertebrates, can see color much like humans can. This discovery, published in the March 2009 issue of Genome Research, may enhance scientists’ understanding of how color vision evolved in early vertebrates over the last 450 million years of evolution.
