Disease opened door to invading species in California
03-12-2007 · EurekAlert!
Plant and animal diseases can play a major and poorly appreciated role in allowing the invasion of exotic species, which in turn often threatens biodiversity, ecological function and the world economy, researchers say in a new report. In particular, a plant pathogen appears to have opened the gate for the successful invasion of non-native grasses into much of California, one of the world's largest documented cases of invading species and one that dramatically changed the history and ecology of a vast grassland ecosystem.

Plant viruses from past provide ecological clues
10-08-2007 · EurekAlert!
Taking the medical history of a grassland may seem a bit esoteric. However, scientists have discovered plant viruses from as early as 1917 containing information crucial not only for plant scientists, but for those in ecology, human health and bioterrorism. Carolyn Malmstrom at Michigan State University isolated historical viral RNA sequences in native and invasive grasses revealing a complex picture of struggles of species, interactions of insects and implications for the ways viruses behave today.

Alien predators are more dangerous than native predators
03-13-2007 · EurekAlert!
Introduced predators such as foxes and cats are twice as deadly as native predators to Australia’s unique native animals, says new research. The finding, published this week in Proceedings of the Royal Society B, is the first confirmation of what has been a long-held hypothesis among scientists. It also highlights the heavy continuing impact of these predators long after their introduction and that Australia's fauna has been among the hardest hit in the world.

New study shows greenback cutthroat trout involved in recovery effort misidentified
09-05-2007 · EurekAlert!
A new study led by the University of Colorado at Boulder indicates biologists trying to save Colorado's native greenback cutthroat trout from extinction over the past several decades through hatchery propagation and restocking efforts have, in most cases, inadvertently restored the wrong fish.

The closest look ever at native human tissue
12-05-2007 · EurekAlert!
Seeing proteins in their natural environment and interactions inside cells has been a long-standing goal. Using an advanced microscopy technique called cryo-electron tomography, researchers from the European Molecular Biology Laboratory have visualized proteins responsible for cell-cell contacts for the first time. In this week's issue of Nature they publish the first 3-D image of human skin at molecular resolution and reveal the molecular Velcro-like organization that interlinks cells.

Cells, dyes and videotape: Online scientific methods journal incorporates multimedia
11-03-2006 · EurekAlert!
Observing the microscopic mysteries of embryos, cells and chromosomes is feasible with advanced live imaging technologies. In space and time, researchers can follow the fates of embryos, track migrating cells and watch how molecules signal and interact with each other -- all in their native environments. The current issue of CSH Protocols includes biomedical research techniques that incorporate this "cellular cinematography" and -- for the first time -- adds multimedia content in the form of movie clips.

A case of mistaken identity for the Ivory-billed Woodpecker?
03-14-2007 · EurekAlert!
Video evidence that an extinct woodpecker is alive and well in Arkansas, USA may prove to be a case of mistaken identity. Research published today in the open access journal BMC Biology shows how fleeting images thought to be the Ivory-billed Woodpecker Campephilus principalis could be another native woodpecker species.
