Presentations Spring/Summer 2012

The Aquatic Toxicology Laboratory at St. Cloud State University remains active with multiple scheduled presentations:

Dan Rearick presented the results of his predation trials at the Midwest meeting of the Society of Environmental Toxicology & Chemistry in Minneapolis (March 2012) and at the Minnesota Wastewater treatment Plant Operators meeting (March 2012). Kelsey Lesteberg discussed the timing of sexual differentiation in fathead minnows at the Midwest meeting of the Society of Environmental Toxicology & Chemistry in Minneapolis (March 2012). Dr. Schoenfuss will give a presentation summarizing research on endocrine active compounds at the MN Stormwater Steering Committee meeting in Minneapolis (April 2012) and on Earth Day at the Environmental Learning Center in Spicer, MN. Dan Rearick and Dr. Schoenfuss will attend the American Water Resources Association Meeting on Emerging Contaminants in June in Denver, CO to discuss their respective research projects. Kelsey Lesteberg will present a presentation at the American Fisheries Society Meeting in Minneapolis in August 2012 to review her study on muscle fiber type differentiation in Hawaiian climbing gobioid fishes. Stay tuned - more presentation announcements are sure to follow!

Another Hawaiian Field Season Completed

Dr. Schoenfuss once again visited field sites in Hawai'i during March 2012 to continue his long-term studies of Hawaiian stream ecology. With the help from collaborators from Clemson University, the University of Minnesota, and support from the Division of Aquatic Resources (Department of Land and Natural Resources, State of Hawai'i) another successful field season was completed.

This field season was used to answer questions regarding the physiology of fish muscle that allows for the climbing of tall waterfalls; the ability of prey from different Hawaiian islands to escape predators; and the anatomy of the jaw apparatus as it relates to feeding and climbing in Sicyopterus stimpsoni.
