Stefan Dennenmoser, PhD candidate


Stefan began his Ph.D. in January 2009, and he is studying phylogeography and local adaptation in prickly sculpin (Cottus asper). Prickly sculpin are found along the western coast of North America, from Alaska to California, largely west of the Continental Divide. Despite its broad distribution and repeated instances of coexistence with lacustrine threespine stickleback, we know relatively little about the basic ecology of this species (see also here and here). Much of the published work to date has focused on interactions between prickly sculpin and coastrange sculpin (e.g., White & Harvey 1999).

Before arriving in Calgary, Stefan obtained a diploma thesis from the University of Kiel in Germany. During this time, he studied various aspects of intraspecific competition in rock shrimp in Martin Thiel's lab in Chile. More recently, he has studied fiddler crabs in Panama, dolphins in the Azores, and freshwater shrimp in Germany. Through these activities, he developed expertise in behavioural observations, morphometrics, and molecular evolution.
