Invasive species can exert rapid depletion of resources after introduction and, in turn, affect their own population density. Additionally, management actions can have direct and indirect effects on demography. Physiological variables can predict demographic change but are often restricted to snapshots-in-time and delayed confirmation of changes in population density reduces their utility. To evaluate the relationships between physiology and demography, we assessed metrics of individual and demographic stress (baseline and 1-h corticosterone (CORT), body condition and bacterial killing ability) in the invasive snake Boiga irregularis on Guam collected in intervals of 10–15 years. We also assessed potential discrepancies between different …

Student Research, Papers, and Creative Works
In aquatic ecosystems, fungi play an essential role in decomposing leaves and making nutrients available to other organisms such as invertebrates and detritivores. Therefore, it is useful to quantify the amount of fungal biomass growing on submerged leaves, and this quantity can be estimated by measuring the chemical ergosterol, which is found only in fungi. Gessner (2005) developed an ergosterol extraction protocol using lipid extraction, purification with solid-phase extraction (SPE), and analysis with high-performance liquid chromatography (HPLC). However, not all of the equipment mentioned in the protocol was available at the University of Minnesota-Morris. Therefore, the goal of this project …
