2. Why the best things come to those who wait
   10-19-2006 · EurekAlert!
   Pushing to the front of the queue is not the best ploy for males who want to propagate their genes according to scientists from the University of Exeter. Dr David Hodgson and Dr David Hosken from the University of Exeter's School of Biosciences studied female mating with multiple males, especially species who mate with more than one partner in rapid succession, and discovered why the last male in line is most likely to impregnate the female.

3. Alpine bird numbers on the slide due to high-altitude ski runs
   01-16-2007 · EurekAlert!
   High-altitude ski runs are seriously affecting Alpine birds, ecologists have found for the first time. Writing in the January issue of the Journal of Applied Ecology, Italian ecologists warn that ski pistes above the tree line result in fewer species and lower numbers of birds compared with natural grassland at similar altitudes. Ski developers should use new, environmentally-friendly techniques when constructing pistes in future, they say.

   12-03-2007 · EurekAlert!
   The spread of two invasive alien freshwater mussel species -- the zebra mussel and the quagga mussel -- appears to be controlled in part by calcium levels in streams and lakes, and a new risk assessment based on water chemistry suggests the Great Plains and American Southwest could be next in line for invasion.

6. New genetic lineage of Ebola virus discovered in great apes
   11-12-2007 · EurekAlert!
   Research scientists from the IRD and the International Medical Research Centre of Franceville in Gabon recently succeeded in mapping virus sequences from samples taken from anthropoid apes. Analysis of this genetic material demonstrated the existence of a new lineage genetic of the Zaire species. It also revealed that genetic recombination events, processes extremely rare for this type of virus, would have taken place between 1996 and 2001.

   12-20-2007 · EurekAlert!
   Global warming and other human-caused ecological changes are outpacing the ability of species to adapt, resulting in greater threats of disease, reduced diversity in plant and animal communities, and an overall loss of natural heritage, according to research presented at a University of California, Los Angeles, summit and published in the peer-reviewed journal Molecular Ecology.

9. How baby fish find a home
   01-16-2008 · EurekAlert!
   University of Miami researcher Claire Paris will use a groundbreaking observational tool, the OWNFOR (Orientation With No Frame Of Reference), a kite-like drifting device that allows researchers to detect and quantify the orientation of larval coral reef fish in the pelagic environment. This invention provides a less labor intensive, more precise way of tracking the dispersal of larval and juvenile marine species. The OWNFOR larval monitoring system will be tested through funding from the Australian Museum; Hermon Slade Foundation.

10. Slow-motion video study shows shrews are highly sophisticated predators
    02-07-2008 · EurekAlert!
    The traditional view that shrews are primitive mammals is challenged by a new study of the hunting methods of an aquatic member of the species, the water shrew, that finds it uses remarkably sophisticated hunting that allow it to catch its prey as readily in the dark as in daylight.
