A Cophylogenetic Analysis Of Fungus Gardening Ants And Their Symbiotic Fungi, Katherine Beigel
Biology Theses
Fungus-growing ants (Tribe Attini) and their fungal cultivars share a 50-million-year coevolutionary history. Large scale phylogenetic analyses depict a strong co-phyletic signal among ants and their farmed fungi yet fungus sharing among unrelated ant lineages is somewhat widespread. An overview of sharing has been hampered by a lack of genetic markers that exhibit intraspecific variation and surveys across geographic regions. For example, previous studies have shown similar sequences of the internal transcribed spacer (ITS) region of fungus in different species of Trachymyrmex, suggesting that these ant species are farming the same fungal clone. To examine whether this was a …

Genetic Studies Of Wildlife, Brittaney L. Buchanan
School of Natural Resources: Dissertations, Theses, and Student Research
Genetic techniques are being more frequently used to understand the biology and management of wildlife species. The wild turkey is one species of genetic interest because the correct identification of individuals to the subspecies level is difficult using traditional methods. Currently phenotypic differences in plumage, especially the upper tail coverts, are used to assign individuals to subspecies. To hunters wanting to complete a “grand slam,” identification of birds’ subspecies is important. This study focuses on the five extant subspecies: Eastern (M. g. silvestris), Osceola (M. g. osceola), Rio Grande (M. g. intermedia), Merriam’s ( …
