Abstract

This project will evaluate evidence of rapid evolutionary divergence of sculpins (two species: Cottus asper and C. cognatus) in proglacial lakes based on morphological traits. The traits will be evaluated using facilities and instruments at UAA. The sculpins have already been collected (by Ms. Heidi Weigner and myself) from the Bering Glacier region of southeast Alaska during the summers of 2002, 2003, and 2004. The geologic dynamics of the region-- dictated by the Bering Glacier-- offer a unique opportunity to observe rapid evolution in fishes as it occurs. Evidence for the evolutionary divergence of the sculpins will be based on gill rakers, eye diameter, spine lengths and other morphological features. The project will be conducted under the direction of Dr. Frank von Hippel and be completed by the spring of 2005. The specific aim of this study is to correlate morphological characteristics to evolutionary divergence in a dynamic environment. Ultimately, if the project produces significant results (the nature of these results will be discussed in the Anticipated Results section), a paper will be submitted for publication in a scholarly journal. Additionally, this project will serve to aid Ms. Heidi Weigner (a doctoral candidate who is also under the guidance of Dr. von Hippel) in her study of the evolution of threespine stickleback in the Bering Glacier region.
