Benthic macroinvertebrates are commonly used as bioindicators of water quality. In a seasonal survey of Willow Creek from 2006-2008, dissolved oxygen was low contributing to poor water quality, with consistently lower DO in upstream versus …

Impact of soil carbon amendments on soil nitrogen, biomass production and vegetative composition in the Biocore Prairie – Deena Weiss
(L&S Honors Sophomore Honors Research Apprenticeship recipients) A major obstacle faced by the Biocore Prairie restoration on the UW-Madison campus is high soil nitrogen, encouraging the growth of nitrophilic weeds over native prairie species. We …
Digital Photography and Image Analysis to Measure Vegetative Cover in the Biocore Prairie – Caitlin Butte
(L&S Honors Sophomore Honors Research Apprenticeship recipients) Estimating ground coverage is a very useful procedure for characterizing vegetation and assessing its growth and development over time. Visual estimation methods are most widely used, but show …
Penstemon digitalis flowers in Biocore Prairie exhibit nectar replenishment when exposed to periodic nectar removal and artificial pollination – Liliana Palencia and Molly Overby
(L&S Honors Sophomore Honors Research Apprenticeship recipients) Pollinators perform nectar removal and pollination. Though research shows that pollinator visits prompt nectar replenishment, it is unclear whether nectar replenishment is differentially affected by nectar removal and/or …
Use of Bloom’s Taxonomy to Claassify Temporal Problem-solving Strategies of Two Biology Students – Michael Kerins
According to Bloom’s taxonomy, intellectual problem-solving development can be categorized as a series of cognitive abilities that start at low-level skills, like factual recollection, and build to higher level skills, like synthesizing different viewpoints and …
Ongoing Study on The Effects of Lake Marion Dam on Black Earth Creek – Kirsten Rhude
(L&S Honors Sophomore Honors Research Apprenticeship recipients) The Wisconsin DNR is requiring the Village of Mazomanie to remove or repair the Lake Marion Dam on Black Earth Creek in western Dane County. Generally dams have …
Peromyscus maniculatus & Microtus pennsylvanicus show no habitat differentiation in Biocore Prairie – Lauren Brooks
(Hilldale Award recipient) Two rodent species Peromyscus maniculatus and Microtus pennsylvanicus are known to coexist within prairie ecosystems. Despite overlapping resource requirements, I hypothesized that these species exhibit habitat differentiation, with M. pennsylvanicus found in …
Vegetative ground cover is important parameter for species distribution of Peromyscus maniculatus and Microtus pennsylvanicus – Kara Bretzman
Peromyscus maniculatus (deer mouse) andMicrotus pennsylvanicus (meadow vole) are two common small mammals found in the Lakeshore Nature Preserve. P. maniculatus is known to be a vegetative generalist, whereas M. pennsylvanicus is exclusive to grasses and forbs. This study measured relative …
QTL Analysis of Anthocyanin Expression in Brassica rapa – Max Wilson, Jaffna Mathiaparanam, John Riley
Anthocyanin pigmentation is used as a quantitative trait to study genetics in educational settings. We are conducting a Quantitative Trait Locus (QTL) analysis to identify the genes involved in expression of anthocyanin pigments in hypocotyls …
A Study of Trichome Expression in Brassica rapa and Future Educational Opportunities – Natalie Tupper, Sophie Carr, Kimberli Ward
Our research will use a QTL analysis to identify the location and nature of genes in the Brassica rapa genome that condition the expression of trichomes, hair-like tissues that form on leaves of seedlings. The …
