Effects of Corridors on Genetics of a Butterfly in a Landscape Experiment
To investigate the possible role of landscape connectivity on the genetic structure of isolated populations, we examined the effects of habitat corridors on the population genetics of a vagile butterfly species, Junonia coenia, within a largescale, experimental system. Using allozyme electrophoresis, a total of nine loci were identified and scored, six of which exhibited polymorphism. Our data demonstrated consistently higher levels of expected (He) and observed (Ho) heterozygosity in butterflies sampled from patches connected by corridors compared to unconnected patches. A t-test comparing He and Ho in connected versus unconnected patches found a marginally significant difference in one locus, the glycolytic enzyme phosphoglucose isomerase (PGI). Connected patches exhibited overall lower FST values compared to unconnected patches, indicating potentially increased levels of gene flow due to corridors. Our results support previous investigations on dispersal and population size for J. coenia, and show that higher dispersal through corridors promotes genetic variability at a locus (PGI) implicated in dispersal and fitness in butterflies.

Genetic and extracellular enzyme survey of planktonic communities of aquatic habitats in Green Lakes Valley, 2017
Preliminary work done in the soils of Green Lakes Valley (GLV) has shown that the microbial communities are generally carbon and phosphorus limited. While most working examining nutrient limitations in GLV has focused on the terrestrial environment, the aquatic environments lack the same study. Longterm monitoring of the lakes in GLV show that there are shifts in carbon availability (quantity and quality) over course of the Colorado alpine growing season. These shifts have been attributed to changes in the source of DOC as snow packs melt out and flow rates decline in the valley altering the ratio of internal (autochthonous) to external (allochthonous) carbon input to the lakes. We examined the links between the biogeography of planktonic communities and the functional response of those communities to shifting nutrient limitations to test the idea that nutrient limitation and composition of planktonic communities are linked both temporally and spatially in GLV. We determined the composition of GLV’s planktonic communities using amplicon sequencing of the small ribosomal subunit sequences (16S, 18S rDNA) and determined nutrient limitations using extracellular enzyme activity (EEA) assays to examine if communities shifted in conjunction with shifts in EEA. We observed that shifting composition in the planktonic communities of GLV mirrored shifts in nutrient limitation (primarily carbon and phosphorus limitation) over the course of the alpine growing season. Alpine and sub-alpine lakes showed opposite trends in the EEA of carbon acquisition enzymes while all lakes showed high activity for phosphorus acquisition enzymes. The planktonic communities were consistently phosphorus limited throughout the study, but carbon limitation was relieved in the alpine lakes as the season progressed while sub-alpine lakes became more carbon limited. The most likely mechanism behind the observed shifts in carbon limitation are the previously studied shifts where DOC is sourced in the va
Genetic survey of bacterioplankton communities of aquatic habitats in Green Lakes Valley, 2014 - 2017
Previous work has shown high-elevation ecosystems are especially susceptible to the effects of climate change, but little work has been done on microbial communities in high-elevation aquatic systems. Therefore, my research aimed to improve our understanding of the composition, stability, and factors controlling microbial communities in high-elevation lakes in the Front Range of the Colorado Rocky Mountains. I studied seasonal and inter-annual variations in bacterial (16S rDNA) and eukaryotic (18S rDNA) microbial communities at multiple locations (inlet, outlet, three depths in the water column) within alpine lakes over four years (2014-2017). Communities significantly differed between lake inlets and the lakes as a whole across sampling dates. The most significant variable controlling 16S and 18S community composition was lake discharge rate, indicating that water residence times play a strong role in structuring communities.

SGS-LTER Genetic Structure of Metapopulation of Black-Tailed Prairie Dogs on the Central Plains Experimental Range and Pawnee National Grassland in Nunn, Colorado, USA 1997-1998
This data package was produced by researchers working on the Shortgrass Steppe Long Term Ecological Research (SGS-LTER) Project, administered at Colorado State University. Long-term datasets and background information (proposals, reports, photographs, etc.) on the SGS-LTER project are contained in a comprehensive project collection within the Digital Collections of Colorado (http://digitool.library.colostate.edu/R/?func=collections&collection_id=3429). The data table and associated metadata document, which is generated in Ecological Metadata Language, may be available through other repositories serving the ecological research community and represent components of the larger SGS-LTER project collection. Additional information and referenced materials can be found: http://hdl.handle.net/10217/83465. Thirteen colonies of black-tailed prairie dogs were studied within a 264-km2 area of the Central Plains Experimental Range and the Pawnee National Grasslands in Weld County, Colorado. Tissue Collection, DNA Extraction, and microsatellite genotype scoring was performed.
Genetic Diversity and Spatial Structure of Spartina alterniflora in on the Eastern Shore of Virginia
Nine polymorphic microsatellite loci were used to quantify the genetic characteristics (e.g., allelic richness,diversity, polyploidy, fixation index) of the S. alterniflora populations at five salt marshes on the Eastern Shore of Virginia (Northampton Co.), as well as to measure the spatial structure (size and shape of clones) of a single population in Upper Phillips Creek marsh (UPC), a marsh that experienced dieback. Over 250 individual plant samples were collected at three spatial scales for these experiments
