The ritualized courtship of the Red-legged salamander, Plethodon shermani, has been studied extensively. Males and females possess brightly colored red legs, but little is known about the implications of this coloration on mate choice. An alternative hypothesis is that coloration may be used as a warning signal to predators. Animals...

Climate change is predicted to affect ecosystems, including systems already stressed by human impacts. One ecosystem that is already highly impacted by human land use is the cold headwater stream system of the Pacific Northwest. One method of assessing the function of an ecosystem is by using an indicator species....
Sexual selection can influence the mating system of an organism through multiple mechanisms. These mechanisms result in variation in reproductive success among individuals, and include scramble competition, endurance rivalries, contests, mate choice and cryptic choice, and sperm competition. Understanding the mating system of a species requires the identification of which...
It is good practice to fully understand components of an ecosystem if we hope to preserve its biodiversity. A problem is that we know very little about some organisms and nothing of others. Studies that investigate an organism’s basic biological, ecological and physiological life history variables advance our knowledge of...
