Drone Up! Quantifying Whale Behavior From a New Perspective Improves Observational Capacity

Creator:: Lemos, Leila, Chandler, Todd E., Torres, Leigh G., and Nieukirk, Sharon L.
Abstract:: During traditional boat-based surveys of marine megafauna, behavioral observations are typically limited to records of animal surfacings obtained from a horizontal perspective. Achieving an aerial perspective has been restricted to brief helicopter or airplane based observations that are costly, noisy, and risky. The emergence of commercial small unmanned aerial systems...

Developmental rate: A unifying mechanism for sympatric divergence in postglacial fishes?

Creator:: Mcphee, Megan V., Noakes, David L. G., and Allendorf, Fred W.
Abstract:: Morphologically divergent ecotypes arise in fish populations on postglacial time scales, and resource polymorphisms are often invoked to explain their origin. However, genetic recombination can constrain the ability of divergent selection to produce reproductive isolation in sympatry. Recombination breaks up favorable combinations of traits (”adaptive suites”) if individual traits are...

Patterns of color phase indicate spawn timing at a Nassau grouper Epinephelus striatus spawning aggregation

Creator:: Archer, Stephanie K., Heppell, Scott A., Semmens, Brice X., Pattengill-Semmens, Christy V., Bush, Phillippe G., Mccoy, Croy M., and Johnson, Bradley C.
Abstract:: Nassau grouper Epinephelus striatus are a large bodied, top level predator that is ecologically important throughout the Caribbean. Although typically solitary, Nassau grouper form large annual spawning aggregations at predictable times in specific locations. In 2003, The Cayman Islands Marine Conservation Board established protection for a newly rediscovered Nassau grouper...

Big fishery, big data, and little crabs: Using genomic methods to examine the seasonal recruitment patterns of early life stage Dungeness crab (Cancer magister) in the California Current Ecosystem

Creator:: Lee, Elizabeth M. J. and O'Malley, Kathleen G.
Abstract:: The California Current Ecosystem (CCE) is a dynamic marine ecosystem from which many socioeconomically important fisheries species are harvested. Here, a genotyping- by-sequencing (GBS) approach was used to examine genomic variation in an early life stage (megalopae) of the Dungeness crab (Cancer magister), which constitutes the most valuable single-species commercial...

Transferrin variation and population differentiation in black-tailed deer

Creator:: Chinn, Edwin Kan Kit
Abstract:: Transferrin of Columbian black-tailed deer (Odocoileus hemionus columbianus) displayed two types of polymorphism. One type involved differences in sialic acid content. The nature of the other polymorphism is not known. A hypothesis for three codominant alleles at a common locus was proposed and tested by using the Hardy-Weinberg Principle. The...

Host Identity Matters in the Amphibian-Batrachochytrium dendrobatidis System: Fine-Scale Patterns of Variation in Responses to a Multi-Host Pathogen

Creator:: Gervasi, Stephanie, Gondhalekar, Carmen, Olson, Deanna H., and Blaustein, Andrew R.
Abstract:: Species composition within ecological assemblages can drive disease dynamics including pathogen invasion, spread, and persistence. In multi-host pathogen systems, interspecific variation in responses to infection creates important context dependency when predicting the outcome of disease. Here, we examine the responses of three sympatric host species to a single fungal pathogen,...

Temporal Genetic Variance and Propagule-Driven Genetic Structure Characterize Naturalized Rainbow Trout (Oncorhynchus mykiss) from a Patagonian Lake Impacted by Trout Farming

Creator:: Benavente, Javiera N., Seeb, Lisa W., Seeb, James E., Arismendi, Ivan, Hernández, Cristián E., Gajardo, Gonzalo, Galleguillos, Ricardo, Cádiz, Maria I., Musleh, Selim S., and Gomez-Uchida, Daniel
Abstract:: Knowledge about the genetic underpinnings of invasions—a theme addressed by invasion genetics as a discipline—is still scarce amid well documented ecological impacts of non-native species on ecosystems of Patagonia in South America. One of the most invasive species in Patagonia’s freshwater systems and elsewhere is rainbow trout (Oncorhynchus mykiss). This...

Population Genetics of American Pika (Ochotona princeps) : Investigating Gene Flow and Genetic Diversity Across Multiple, Complex Landscapes

Creator:: Castillo, Jessica A.
Abstract:: American pikas (Ochotona princeps) are considered an indicator species of climate change. Adaptations for cold climates and active winters make pikas particularly sensitive to increasing temperatures. This, combined with evidence that multiple historically occupied populations have been extirpated within the past century, contributed to American pikas becoming a focal species...

Spatial Ecology and Species Interactions among Predators and their Prey

Creator:: Ruprecht, Joel S.
Abstract:: Carnivores have disproportionate effects in ecological systems but understanding their exact influences on ecosystems is a matter of great complexity and debate. Predators directly impact prey by killing them, and indirectly by modifying their behavior in response to predation risk. Yet how species interact, both among members of a carnivore...

The influence of social structure and molecular evolution on genetic diversity in the sperm whale (Physeter macrocephalus)

Creator:: Alexander, Alana
Abstract:: The sperm whale (Physeter macrocephalus) shows some of the most derived characteristics of any mammal: a large body size, large brain, complex social organization and a capacity for deep foraging dives that few other marine mammals can match. Despite a history of exploitation that removed hundreds of thousands of individuals,...
