Prevalence of the gene lsr2 among the genus Mycobacterium and an investigation into changes in biofilm formation when inactivating lsr2 regulated genes in Mycobacterium smegmatis
Mycobacterium smegmatis is a non-pathogenic model organism commonly used to study the human pathogen Mycobacterium tuberculosis. M. smegmatis has a rough colony morphology and is capable of forming biofilms, however, when the DNA-regulating protein Lsr2 is inactivated the bacteria forms a smooth …

A Geographic Mosaic of Speciation in Eurosta solidaginis
Ecological speciation occurs when divergent selection in different habitats creates strong selection for reproductive isolation which counteracts the homogenizing effects of gene flow between populations using those different habitats. Multiple divergent selection pressures can affect isolation and …

The effect of urbanization on the stopover ecology of neotropical migrant songbirds
I conducted spring migration point counts and vegetation surveys at 29 forest patches in the Chicago, IL metropolitan area in 2012 and 2013. The forest patch selection was designed to test the effects of patch size, distance from the Lake Michigan shoreline and degree of urbanization. I conducted …

Characterizing the role of ATP-binding cassette transporters in triterpenoid wax bloom production
Some plants have developed lineage-specific mechanisms to increase water retention during drought conditions, including thick epicuticular wax coatings called wax blooms. However, the process underlying synthesis and especially the transport of wax bloom compounds to the leaf surface have yet to be …

Temporal Change in Community Composition, Ecological Niche, and Phenotypic Selection in Minnesota’s Rare Arctic Relict Plants
Rare, arctic relict plant populations of Minnesota, found in the cool and moist microclimate produced along the cold waters of Lake Superior, face an uncertain future due to anthropogenic climate change. In this study, we used a variety of approaches to examine the contemporary impacts of climate …

Use Of Multi-Gear Sampling To Improve Abundance Estimates Of Demersal Coregonids In The Laurentian Great Lakes
Demersal species such as Bloater (Coregonus hoyi), Shortjaw Cisco (Coregonus zenithicus), Lake Whitefish (Coregonus clupeaformis) and Round Whitefish (Prosopium cylindraceum) play a vital role in both the Laurentian Great Lakes food webs and the commercial fishing industry. Hydroacoustic sampling …

Drivers of reproductive variability in Vaccinium cespitosum and vaccinium vitis-idaea in northeastern Minnesota
Multiple factors affect reproductive variability within a population, and understanding these factors is important for making informed land management decisions. I investigated how clonality impacts reproductive variability in Vaccinium cespitosum and Vaccinium vitis-idaea (Ericaceae), and how the …

Fibronectin and Laminin, extracellular matrix proteins, have an origin in mesoderm tissue and promote anterior neural tube closure in zebrafish
The neural tube, the precursor to the vertebrate central nervous system, forms through the process of neurulation. During neurulation, a flat neural plate folds and the lateral edges bind to form a closed tube. Failure of neurulation results in neural tube defects (NTD). In humans, NTD causes …
