A new species of western Atlantic lizardfish (Teleostei: Synodontidae: Synodus) and resurrection of Synodus bondi Fowler, 1939, as a valid species from the Caribbean with redescriptions of S. bondi, S. foetens (Linnaeus, 1766), and S. intermedius (Agassiz, 1829)

Creator:: Frable, Benjamin W., Baldwin, Carole C., Luther, Brendan M., and Weigt, Lee A.
Abstract:: Western Atlantic synodontid species were studied as part of an ongoing effort to reanalyze Caribbean shorefish diversity. A neighbor-joining tree constructed from cytochrome c oxidase I (COI) data revealed 2 highly divergent genetic lineages within both Synodus intermedius (Agassiz, 1829) (Sand Diver) and S. foetens (Linnaeus, 1766) (Inshore Lizardfish). A...

Comparing anuran performance and movement

Creator:: Bredeweg, Evan M.
Abstract:: Movement in an important component of an animal’s life cycle when it relies on both aquatic and terrestrial habitats. When multiple species overlap in the use of these habitats, they rely on other methods to reduce competition for shared resources. This dataset measured the jumping performance and movement behavior of...

Patterns of loggerhead turtle ontogenetic shifts revealed through isotopic analysis of annual skeletal growth increments

Creator:: Ramirez, Matthew D., Avens, Larisa, Seminoff, Jeffrey A., Goshe, Lisa R., and Heppell, Selina S.
Abstract:: Ontogenetic changes in resource use often delimit transitions between life stages. Ecological and individual factors can cause variation in the timing and consistency of these transitions, ultimately affecting community and population dynamics through changes in growth and survival. Therefore, it is important to document and understand behavioral and life history...

The Factors Affecting the Diets of Groundfish in the Gulf of Alaska : Ecological and Modeling Considerations

Creator:: Thompson, Kevin A.
Abstract:: Marine systems undergo changes in community composition over time as a result of a variety of environmental and anthropogenic factors. Understanding these community changes and the factors that drive them is critical for ecosystem management of marine resources. The Gulf of Alaska (GOA) is a large marine ecosystem that includes...

Efficacy of sodium fluoroacetate in reducing ground squirrel damage to alfalfa

Creator:: Kalinowski, Stephan A.
Abstract:: Damage by Belding's ground squirrel (Spermophilus beldingi) to alfalfa (Medicago sativa) and the efficacies of various poisoning regimes to reduce damage were evaluated during March-July, 1976 and 1977. Regimes examined were designed to measure the effect of 3 variables on damage to alfalfa caused by squirrels including; timing of application,...

Influence of Oceanographic Conditions on Copepod (Calanus pacificus) Genetic Expression

Creator:: Bynes, Kenya S.
Abstract:: RNAseq data among copepods (Calanus pacificus) were sampled and analyzed in relation to oceanographic and climatic conditions to determine if new information derived from such an approach might assist applications that use copepods as ecosystem indicators to predict fishery yields. These samples were taken as part of long-term studies conducted...

Prey swimming behavior and culture techniques for copper, Sebastes caurinus, and quillback rockfish, S. malinger

Creator:: Gilbert, Thom H.
Abstract:: Rotifers and brine shrimp (Artemia) are important prey items for rearing marine fish larvae. Their availability in the water column may be reduced when they are transferred to larval rearing tanks at lower temperature. In this study, Brachionus rotundiformis (SS-type) and Brachionus plicatilis (L-type) were semi-continuously cultured and fed on...

Sequential isotopic analysis to characterize ontogenetic shifts and growth dynamics of loggerhead sea turtles (Caretta caretta)

Creator:: Ramirez, Matthew D.
Abstract:: Ontogenetic niche theory predicts that as organisms grow they make size-specific changes in habitat use and diet to optimize growth and survival. A variety of factors contribute to growth and survival in different habitats, ultimately leading to variation in life history that can affect population dynamics. An understanding of the...

Vertebral elemental markers in elasmobranchs : potential for reconstructing environmental history and population structure

Creator:: Smith, Wade D.
Abstract:: Differences in the chemical composition of calcified structures can be used to reveal natal origins, connectivity, metapopulation structure, and reconstruct the environmental history or movement patterns of many marine organisms. Sharks, skates, and rays (elasmobranchs) lack the calcified structures, known as otoliths, that are typically used for geochemical studies of...

Ecology of the northern subpopulation of northern anchovy (Engraulis mordax) in the California Current large marine ecosystem

Creator:: Litz, Marisa N. C.
Abstract:: Northern anchovy (Engraulis mordax) are a dominant forage fish in the California Current large marine ecosystem (CCLME). However, little is known about northern anchovy abundance, distribution, age structure, or population fluctuations relative to ocean conditions in the eastern boundary upwelling system off the U.S. West Coast. This thesis includes three...
