The secret lives of African forest elephants: using genetics, networks, and telemetry to understand sociality
(University of Missouri--Columbia, 2012)
extensive networks of individuals suggesting fission-fusion sociality. Also, adult females at distances of five kilometers or less were more closely related to each other than expected from chance. Known adult females and their associates were tracked...
Multi-scale investigations of gray treefrong movements: patterns of migration, dispersal, and gene flow
(University of Missouri--Columbia, 2005)
habitat adjacent to breeding sites is extensive. Furthermore, dispersal success is affected by matrix composition and inter-pond distance, but juveniles and adults are differently inhibited. Lastly, the type of metapopulation dynamics exhibited...
Coupling, membrane conductance, and ion channel mRNA profiles in the establishment and maintenance of network activity in the crustacean cardiac ganglion
(University of Missouri--Columbia, 2021)
cells together, and identify cells based on gene expression alone. We use single cell RNA-seq and single cell qRT-PCR to measure all contigs or a select set of ion channel, receptor, and gap junction mRNAs. We find these methods do not reproduce...
Conservation genetics of conflict in the Asian elephant, Elephas maximus
(University of Missouri--Columbia, 2021)
The Asian elephant (Elephas maximus) is an endangered species whose distribution spans 13 countries in south, southeast, and insular Asia. The primary threats to the survival of this species include direct conflict, primarily ...
Genetic diversity and distribution of the ringed salamander (ambystoma annulatum) across multiple spatial scales
(University of Missouri--Columbia, 2018)
that correspond to watershed boundaries. Within each cluster, I found evidence for decreased gene flow in recent generations, possibly due to the extensive timber harvest and land conversion of the CIH post European settlement. Over smaller spatial scales, I found...
Developmental programming by xenoestrogens
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Xenoestrogens (XE) are chemicals in the environment that mimic the body's natural steroidal estrogens. Developmental exposure to XE may interfere with ...
