Comparative behavioral biology

Wednesday, May 25th. Wednesday, MAY This has generated a seemingly endless array of dynamically-evolvig coloration phenotypes across the tree of animals. Poison frogs of the family Dendrobatidae exhibit wide variation in coloration. Within this group, bright colorations have evolved independently at least five times, and are known to be involved in predator avoidance, sexual selection, and territoriality.

To understand the mechanisms behind the evolution of conspicuous coloration, I study the genus Phyllobates , where plain bright-yellow species have evolved independently two or three times from dark ancestors with yellow dorsal stripes. In this seminar, I combine results from comparative phylogenetics and field experiments to elucidate the role of predation pressures on the evolution of coloration in this group of frogs, and explore the genetic mechanisms behind this process based on preliminary exome sequencing results.

Abstract: Free-roaming dogs are both a public health and conservation concern because of their potential to transmit diseases such as rabies.

Comparative behavioral biology: Comparative psychology, which.

Understanding domestic dog population dynamics and how they are impacted by interventions, such as rabies vaccination, is vital for the planning and implementing of such disease control efforts. Our four-year longitudinal study compared the demography of free-roaming domestic dogs in villages with and without a rabies vaccination campaign near Serengeti National Park in Tanzania.

We identified and followed the life histories of 2, owned free-roaming domestic dogs living in four rural villages west of Serengeti National Park.
