Relationship between effective population size, inbreeding and adult fitness-related traits in a steelhead (Oncorhynchus mykiss) population released in the wild.
Mol Ecol. 2013 Feb 4;
Authors: Naish KA, Seamons TR, Dauer MB, Hauser L, Quinn TP
Inbreeding is of concern in supportive breeding programmes in Pacific salmonids, Oncorhynchus spp, where the number of breeding adults is limited by rearing space or poor survival to adulthood, and large numbers are released to supplement wild stocks and fisheries.
Identifying Preservation and Restoration Priority Areas for Desert Fishes in an Increasingly Invaded World.
Environ Manage. 2013 Jan 26;
Authors: Pool TK, Strecker AL, Olden JD
A commonly overlooked aspect of conservation planning assessments is that wildlife managers are increasingly focused on habitats that contain non-native species. We examine this management challenge in the Gila River basin (150,730 km(2)), and present a new planning strategy for fish conservation.
Motion-guided attention promotes adaptive communications during social navigation.
Proc Biol Sci. 2013;280(1754):20122003
Authors: Lemasson BH, Anderson JJ, Goodwin RA
Animals are capable of enhanced decision making through cooperation, whereby accurate decisions can occur quickly through decentralized consensus. These interactions often depend upon reliable social cues, which can result in highly coordinated activities in uncertain environments. Yet information within a crowd may be lost in translation, generating confusion and enhancing individual risk.
Centennial-scale fluctuations and regional complexity characterize Pacific salmon population dynamics over the past five centuries.
Proc Natl Acad Sci U S A. 2013 Jan 15;
Authors: Rogers LA, Schindler DE, Lisi PJ, Holtgrieve GW, Leavitt PR, Bunting L, Finney BP, Selbie DT, Chen G, Gregory-Eaves I, Lisac MJ, Walsh PB
Observational data from the past century have highlighted the importance of interdecadal modes of variability in fish population dynamics, but how these patterns of variation fit into a broader temporal and spatial context remains largely unknown.
Frequency and intensity of productivity regime shifts in marine fish stocks.
Proc Natl Acad Sci U S A. 2013 Jan 15;
Authors: Vert-Pre KA, Amoroso RO, Jensen OP, Hilborn R
Fish stocks fluctuate both in abundance and productivity (net population increase), and there are many examples demonstrating that productivity increased or decreased due to changes in abundance caused by fishing and, alternatively, where productivity shifted between low and high regimes, entirely unrelated to abundance.
Pesticides in urban streams and early life stages of pacific coho salmon.
Environ Toxicol Chem. 2013 Jan 7;
Authors: King KA, Grue CE, Grassley JM, Fisk RJ
Pesticides are frequently detected in urban streams and are believed to be primarily the result of homeowner use. Although concentrations in most cases are low (<1 µg/L), there is concern that pesticide inputs threaten efforts to restore and enhance salmon habitat.
Genomic resource development for shellfish of conservation concern.
Mol Ecol Resour. 2012 Dec 27;
Authors: Timmins-Schiffman EB, Friedman CS, Metzger DC, White SJ, Roberts SB
Effective conservation of threatened species depends on the ability to assess organism physiology and population demography. To develop genomic resources to better understand the dynamics of two ecologically vulnerable species in the Pacific Northwest of the United States, larval transcriptomes were sequenced for the pinto abalone, Haliotis kamtschatkana kamtschatkana, and the Olympia oyster, Ostrea lurida.
Characterization of genes involved in ceramide metabolism in the Pacific oyster, Crassostrea gigas
BMC Research Notes 2012, 5:502, DOI 10.1186/1756-0500-5-502
Authors: Timmins-Schiffman E, Roberts SB
Ceramide metabolism is an important part of the vertebrate response to a variety of environmental stressors. Accumulation of ceramide, a lipid, can lead to stress-induced apoptosis. We investigated the conservation of this pathway in invertebrates using the Pacific oyster as a model.
Developing a broader scientific foundation for river restoration: Columbia River food webs.
Proc Natl Acad Sci U S A. 2012 Nov 28;
Authors: Naiman RJ, Alldredge JR, Beauchamp DA, Bisson PA, Congleton J, Henny CJ, Huntly N, Lamberson R, Levings C, Merrill EN, Pearcy WG, Rieman BE, Ruggerone GT, Scarnecchia D, Smouse PE, Wood CC
Well-functioning food webs are fundamental for sustaining rivers as ecosystems and maintaining associated aquatic and terrestrial communities.
Rank and Order: Evaluating the Performance of SNPs for Individual Assignment in a Non-Model Organism.
PLoS One. 2012;7(11):e49018
Authors: Storer CG, Pascal CE, Roberts SB, Templin WD, Seeb LW, Seeb JE
Single nucleotide polymorphisms (SNPs) are valuable tools for ecological and evolutionary studies. In non-model species, the use of SNPs has been limited by the number of markers available. However, new technologies and decreasing technology costs have facilitated the discovery of a constantly increasing number of SNPs.
