Archaeopteryx Was Not Very Bird-like: Inside The First Bird, Surprising Signs Of A Dinosaur Oct 10, 2009
9, 2009) The raptor-like Archaeopteryx has long been viewed as the archetypal first bird, but new research reveals that it was actually a lot less "bird-like" than scientists had believed. In fact, the landmark study led by paleobiologist Gregory M. Erickson of The Florida State University has upended the iconic first-known-bird image of Archaeopteryx (from the Greek for "ancient wing"), which lived 150 million years ago during the Late Jurassic period in what is now Germany.

Biogeography of tick-borne disease Sep 2, 2009
Despite extensive characterization of the genetic diversity in A. marginale geographic strains using major surface protein sequences, little is known about the biogeography and evolution of A. marginale and other Anaplasma species. For A. marginale, MSP1a was shown to be involved in vector-pathogen and host-pathogen interactions and to have evolved under positive selection pressure. (BioMed Central)

Climate Change Makes Migrations Longer For Birds Apr 17, 2009
Published in the Journal of Biogeography, the scientists demonstrate evidence of potential breeding ranges shifting northwards in the future, while the wintering ranges remain stationary for many species. The team used simulation models to see how climate change might affect warblers and found that climate change will have significant impacts, particularly on the projected migration distances for some of the long distance fliers.

The Warbler's Long Winter Journey Gets Longer Apr 16, 2009
In a new study in the Journal of Biogeography, scientists at Durham University and Cambridge University found that migration flights undertaken by warblers in Europe and Asia could be extended by as much as 250 miles by the end of the century. That's because as temperatures rise, the habitats of birds like the whitethroat, which breed in Europe, will need to shift farther north to more hospitable climates. (Time.com)
