I have continued the background discovery process for my research project on songbird and accipiter hawk (hawks that feed on songbirds) migration patterns. A week ago I reviewed a paper on the differential timing of accipiter hawk migration. That particular paper provided a lot to think about and indicated that I may need a more complicated algorithm for my research. This week I found some time to review a paper on weather impacts on hawk migration. I am interested in the research as I will like........ Read more »

I am sure that this question has been keeping you up at night, but rest assured science is working hard to resolve the question. I came across this recent research paper in the scientific journal Evolutionary Ecology. The paper is not publicly available, it is restricted to subscribers. Alexandra T. Stang, Susan B. McRae (2008). Why some rails have white tails: the evolution of white undertail plumage and anti-predator signaling Evolutionary Ecology DOI: 10.1007/s10682-008-9283-z Rails, or Ra........

There have been a number of studies in the past few years analyzing the degree to which various species communicate with other species. I expect that many people might assume that little communication occurs between organisms of separate species, but that's just not true. Clearly there are many non-verbal cues that pass from species to species. Consider a bear staring at you while pawing the ground. While I haven't witnessed this myself, I can only assume that the communication from the bear wo........ Read more »

As I get ready for the beginning of school next week I am still thinking about what my emphasis will be. I am enrolled in a Bachelor's degree program at Boise State in Biology with an emphasis in Ecology, but I must still choose a taxonomy focus of my ecology work. The choices include Entomology, Ornithology, Vertebrate Natural History, Mammalogy, or Aquatic Entomology. I might take more than one. The likely choices include Ornithology (birds) or Mammalogy, although my recent fascina........ Read more »

I have recently registered for the Public Library of Science's Biology feed alerting me to new articles of interest. I have chosen to focus on PLOS as they provide the full content of the published scientific papers to the public. The other science journals restrict public access to the material for some period of time, unless you pay to be a member. Since I am not ready to take that step yet, I have been watching PLOS instead. You might have noticed that it was impossible to get at the or........ Read more »
