Featured Research by Anett Trebitz

Trebitz et al. 2010. Status of non-indigenous benthic invertebrates in the Duluth-Superior Harbor and the role of sampling methods in their detection. J. Great Lakes Res. 36:747-756.

Invasive species can cause considerable ecological and economic damage, so it is important to have a monitoring system in place to detect new arrivals early enough to mount an effective response. But how could early detection monitoring be accomplished most efficiently, given time and budgetary constraints?

Anett Trebitz and her colleagues sought to answer that question. They conducted intensive sampling in a known exotic species ‘hotspot’, followed by numeric ‘what-if’ analyses to determine methodological efficiencies. One major finding: combining multiple search strategies is better than traditional single-gear monitoring. Through their efforts, they discovered several new invertebrate exotics in the Duluth-Superior Harbor.

Anett is a research ecologist with the US EPA Mid-Continent Ecology Division in Duluth. She received her MS from the University of Tennessee and her PhD from the University of Wisconsin-Madison.

Annett cares about how people affect aquatic ecosystems, and currently is part of a team studying linkages between watershed development and the health of Great Lakes coastal wetlands.
