Beached Bones: Exploring the Genetic Impact of Exploitation on the Diversity of Great Whales in the South Atlantic

Creator:: Sremba, Angela L.
Abstract:: Commercial whaling during the 20th century drastically reduced many populations of great whales in the Southern Hemisphere. The Antarctic blue whale, for example, is estimated to have been reduced to less than 0.1% of its original abundance based on catch records and population dynamic models. Despite this population bottleneck, several...

A whale's tale of mtDNA diversity and differentiation : the Antarctic blue whale

Creator:: Sremba, Angela L.
Abstract:: Twentieth century commercial whaling drastically reduced the abundance of great whale populations in the Southern Ocean. Exploitation began on the south Atlantic island of South Georgia, where catch records account for over 175,000 whales killed. Modern whaling within the Southern Ocean depleted populations rapidly, and by 1966, hunting blue whales...

Assessing population-level variation in the mitochondrial genome of Euphausia superba using 454 next-generation sequencing

Creator:: Johansson, Mattias, Duda, Elizabeth, Sremba, Angela L., Banks, Michael, and Peterson, William
Abstract:: The Antarctic krill (Euphausia superba Dana 1852) is widely distributed throughout the southern ocean, where it provides a key link between primary producers and upper trophic levels and supports a major commercial fishery. Despite its ecological and commercial importance, genetic population structure of the Antarctic kill remains poorly described. In...

The mitochondrial genomes of Euphausia pacifica and Thysanoessa raschii sequenced using 454 next-generation sequencing, with a phylogenetic analysis of their position in the Malacostracan family tree

Creator:: Johansson, Mattias L., Sremba, Angela L., Feinberg, Leah R., Banks, Michael A., and Peterson, William T.
Abstract:: Euphausiid krill play a critical role in coastal and oceanic food webs, linking primary producers to upper trophic levels. In addition, some species support commercial fisheries worldwide. Despite their ecological importance, the genetics of these important species remain poorly described. To improve our understanding of the genetics of these ecological...

Circumpolar Diversity and Geographic Differentiation of mtDNA in the Critically Endangered Antarctic Blue Whale (Balaenoptera musculus intermedia)

Creator:: Sremba, Angela L., Hancock-Hanser, Brittany, Branch, Trevor A., LeDuc, Rick L., and Baker, C. Scott
Abstract:: The Antarctic blue whale (Balaenoptera musculus intermedia) was hunted to near extinction between 1904 and 1972, declining from an estimated initial abundance of more than 250,000 to fewer than 400. Here, we describe mtDNA control region diversity and geographic differentiation in the surviving population of the Antarctic blue whale, using...

Evolution and Expression of TSR-domain proteins in cnidarian-dinoflagellate symbiosis

Creator:: Tan, Kenneth
Abstract:: The symbiotic relationship between cnidarians, such as corals and sea anemones, and dinoflagellates plays a crucial role in supporting the diversity and productivity of coral reefs. Critical to the symbiosis is the recognition process between host and symbiont at the onset of symbiosis, which involves the host innate immune system....

Ontogenetic and spatial variability in trophic biomarkers of juvenile saffron cod (Eleginus gracilis) from the Beaufort, Chukchi and Bering Seas

Creator:: Copeman, Louise A., Laurel, Benjamin J., Boswell, Kevin M., Sremba, Angela L., Klinck, Karolin, Heintz, Ron A., Vollenweider, Johanna J., Helser, Thomas E., and Spencer, Mara L.
Abstract:: Climate models indicate the Arctic will undergo dramatic environmental change with forecasted increases in temperature and river runoff. Saffron cod (Eleginus gracilis) is abundant in nearshore waters and appears in the diet of many Arctic sea birds and marine mammals; however, little is known about its early ecology and consequently...

Degradation kinetics of taxol using mass spectroscopy

Creator:: Zhang, Jun
Abstract:: Paclitaxel is a very important anticancer drug commonly called Taxol®. We know from previous work (Hoffman, et al., 1998) that Taxol exists in filbert, Corylus avellana L. material. Quantification of Taxol in filbert plant material is painstaking and hitherto was accomplished by rapidly processing single batches in a complicated procedure...

Influence of soil acidity upon nodulation and growth characteristics of Trifolium subterraneum L.

Creator:: Almendras, Angela S.
Abstract:: Previous research had identified four serogroups of Rhizobium trifolii indigenous to Abiqua soil (fine, mixed, mesic, Cumulic Ultic Haploxerolls). Nodulation of subterranean clover (Trifolium, subterraneum L.) by two of the serogroups, 6 and 36, was influenced by the application of CaC0₃ to the soil. The studies described in this thesis...
