Population Structure and Phylogeography in Nassau Grouper (Epinephelus striatus), a Mass-Aggregating Marine Fish

Creator:: Jackson, Alexis M., Semmens, Brice X., de Mitcheson, Yvonne Sadovy, Nemeth, Richard S., Heppell, Scott A., Bush, Phillippe G., Aguilar-Perera, Alfonso, Claydon, John A. B., Calosso, Marta C., Sealey, Kathleen S., Schärer, Michelle T., and Bernardi, Giacomo
Abstract:: To address patterns of genetic connectivity in a mass-aggregating marine fish, we analyzed genetic variation in mitochondrial DNA (mtDNA), microsatellites, and single nucleotide polymorphisms (SNPs) for Nassau grouper (Epinephelus striatus). We expected Nassau grouper to exhibit genetic differentiation among its subpopulations due to its reproductive behavior and retentive oceanographic conditions...

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...

The Effect of Novel Research Activities on Long-term Survival of Temporarily Captive Steller Sea Lions (Eumetopias jubatus)

Creator:: Shuert, Courtney, Horning, Markus, and Mellish, Jo-Ann
Abstract:: Two novel research approaches were developed to facilitate controlled access to, and long-term monitoring of, juvenile Steller sea lions for periods longer than typically afforded by traditional fieldwork. The Transient Juvenile Steller sea lion Project at the Alaska SeaLife Center facilitated nutritional, physiological, and behavioral studies on the platform of...

Life History and Production of the Western Gray Whale's Prey, Ampelisca eschrichtii Krøyer, 1842 (Amphipoda, Ampeliscidae)

Creator:: Demchenko, Natalia L., Chapman, John W., Durkina, Valentina B., and Fadeev, Valeriy I.
Abstract:: Ampelisca eschrichtii are among the most important prey of the Western North Pacific gray whales, Eschrichtius robustus. The largest and densest known populations of this amphipod occur in the gray whale’s Offshore feeding area on the Northeastern Sakhalin Island Shelf. The remote location, ice cover and stormy weather at the...

Public lands and private waters: scarce mesic resources structure land tenure and sage-grouse distributions

Creator:: Donnelly, J. P., Naugle, D. E., Hagen, C. A., and Maestas, J. D.
Abstract:: Water scarcity in semiarid environments provides a model system to evaluate the role of mesic resources in structuring the distribution and abundance of wildlife. We used remote sensing and point process analyses to evaluate spatio–temporal variability in limited mesic resources in relation to greater sage-grouse (Centrocercus urophasianus) distributions in Oregon,...

An Evaluation of Collaborative Salmon Fishery Management in Prince William Sound, Alaska

Creator:: Sheridan, Thomas M.
Abstract:: Collaborative decision-making is often promoted as a means to achieve socially acceptable and enduring solutions to natural resource management issues, and one that holds promise for resolving “wicked” problems. However, success rates for implementation of collaborative recommendations are unknown. This paper explores challenges to collaborative salmon fishery management in Prince...

Gene expression correlated with delay in shell formation in larval Pacific oysters (Crassostrea gigas) exposed to experimental ocean acidification provides insights into shell formation mechanisms

Creator:: Ventura, Alexander, Durland, Evan, De Wit, Pierre, and Langdon, Chris J.
Abstract:: Background: Despite recent work to characterize gene expression changes associated with larval development in oysters, the mechanism by which the larval shell is first formed is still largely unknown. In Crassostrea gigas, this shell forms within the first 24 h post fertilization, and it has been demonstrated that changes in...

The Western Pacific barred knifejaw, Oplegnathus fasciatus (Temminck & Schlegel, 1844) (Pisces: Oplegnathidae), arriving with tsunami debris on the Pacific coast of North America

Creator:: Chapman, John W., Ta, Nicholas, Miller, Jessica A., Carlton, James T., Miller-Morgan, Timothy, Calvanese, Thomas, Pleus, Allen E., and Burke, James
Abstract:: The Western Pacific Ocean barred knifejaw Oplegnathus fasciatus was found from 2013 to 2015 along the Pacific Coast of North America from Washington to California. The knifejaw was found in derelict vessels that had arrived on the Pacific Coast and that had been lost during the March 2011 Great Japan...

Seasonal distribution and environmental associations among late larval and juvenile rockfish (Sebastes spp.) off Oregon and Washington: new insights based on genetics

Creator:: Johansson, Mattias L., Litz, Marisa N. C., Brodeur, Richard D., Britt, Tristan A., Vanegas, Camilo A., Hyde, John R., and Banks, Michael A.
Abstract:: Cytochrome B sequence data (FASTA format) from the paper “Seasonal distribution and environmental associations among late larval and juvenile rockfish (Sebastes spp.) off Oregon and Washington: new insights based on genetics”. The data was generated from a sample of 2534 unknown, field collected late-larval and juvenile rockfishes from the Pacific...

Classification of Animal Movement Behavior through Residence in Space and Time

Creator:: Orben, Rachael A., Thompson, David R., Tolkova, Irina, and Torres, Leigh G.
Abstract:: Identification and classification of behavior states in animal movement data can be complex, temporally biased, time-intensive, scale-dependent, and unstandardized across studies and taxa. Large movement datasets are increasingly common and there is a need for efficient methods of data exploration that adjust to the individual variability of each track. We...
