Species Richness Of Moths In Parks Surrounded By Varying Levels Of Urbanization Around Nashville, Tennessee, Maxwell Stone, Allie Bennett
Species Richness Of Moths In Parks Surrounded By Varying Levels Of Urbanization Around Nashville, Tennessee, Maxwell Stone, Allie Bennett
Science University Research Symposium (SURS)
Moths can act as indicators of environmental wellness due to their pollution sensitivity and the complexity of biodiversity required to support their life cycles. Urbanization can impact the occurrence of moths in protected green spaces. Higher moth species richness was hypothesized to occur in parks surrounded by more rural areas. Three metropolitan parks were chosen in the Nashville area: downtown, within a suburban neighborhood, and in a rural area. Tree canopy cover and degree of impervious surfaces were assessed for each park and surrounding area using iTreeCanopy. Moths were attracted to a white sheet using a mercury vapor bulb, UV …
A Foundational Population Genetics Investigation Of The Sexual Systems Of Solanum (Solanaceae) In The Australian Monsoon Tropics Suggests Dioecious Taxa May Benefit From Increased Genetic Admixture Via Obligate Outcrossing, Jason T.

Solanum section Leptostemonum is an ideal lineage to test the theoretical framework regarding proposed evolutionary benefits of outcrossing sexual systems in comparison to cosexuality. Theoretically, non-cosexual taxa should support more genetic diversity within populations, experience less inbreeding, and have less genetic structure due to a restricted ability to self-fertilize. However, many confounding factors present challenges for a confident inference that inherent differences in sexual systems influence observed genetic patterns among populations. This study provides a foundational baseline of the population genetics of several species of different sexual systems with the aim of generating hypotheses of any factor—including sexual system—that influences …

Wildlife Damage Management Technical Series
Prairie dogs (Cynomys spp.) occur throughout the prairie states of middle North America from Mexico northward into Canada. They occupy a variety of habitats from prairies to high mountain valleys and sage brush-dominated deserts. The most common species is the black-tailed prairie dog (Cynomys ludovicianus; Figure 1). Prairie dogs are considered a “keystone species.” They provide habitat for many other native, grassland species. Prairie dogs live in colonies or “towns” that can span hundreds to thousands of acres. Depending on the species, their presence is evident by their burrow system. Despite the many ecosystem benefits prairie dogs provide by modifying …
Harnessing Citizen Science And Collections Data For Invasive Plant Surveillance, Adin L. Ring
Harnessing Citizen Science And Collections Data For Invasive Plant Surveillance, Adin L. Ring
Library Map Prize
Our main source of information about the distribution of invasive plants in the United States comes from occurrence records in three categories: biological collections (physical plant specimens in museums), citizen science (opportunistic observations by untrained civilians), and invasion monitoring (structured observation by government or non-profit agencies). This study compiles a set of 3.1 million occurrence records of 3,578 introduced plant species in the continental United States, and infers spatial, temporal, and taxonomic biases by comparing the three categories of data. We find that citizen science contributes the largest bulk of records, and does better capturing visually conspicuous plants and very …
