Modeling potential impacts of three benthic invasive species on the Lake Erie food web Open
Assessing the potential for aquatic invasive species (AIS) to impact ecosystem function and services is an important component of ecological risk assessment. This study focuses on quantifying changes in biomass of food web groups in respon…

Suitability of Laurentian Great Lakes for invasive species based on global species distribution models and local habitat Open
Efficient management and prevention of species invasions requires accurate prediction of where species of concern can arrive and persist. Species distribution models provide one way to identify potentially suitable habitat by developing th…

Risk Analysis and Bioeconomics of Invasive Species to Inform Policy and Management Open
Risk analysis of species invasions links biology and economics, is increasingly mandated by international and national policies, and enables improved management of invasive species. Biological invasions proceed through a series of transiti…

Confronting species distribution model predictions with species functional traits Open
Species distribution models are valuable tools in studies of biogeography, ecology, and climate change and have been used to inform conservation and ecosystem management. However, species distribution models typically incorporate only clim…

Tradeoffs among Ecosystem Services Associated with Global Tilapia Introductions Open
Previous publications have reached different conclusions about the balance between the socioeconomic benefits of tilapia introduction for aquaculture and capture fisheries, and the potential negative impacts of these species on ecosystem s…

Forecasting the Impacts of Silver and Bighead Carp on the Lake Erie Food Web Open
Nonindigenous bigheaded carps (Bighead Carp Hypophthalmichthys nobilis and Silver Carp H. molitrix; hereafter, “Asian carps” [AC]) threaten to invade and disrupt food webs and fisheries in the Laurentian Great Lakes through their high cons…
