Quantitative PCR analysis used to characterize physiological changes in brain tissue of senescent sockeye salmon.
Biogerontology. 2013 Aug 15;
Authors: Storer CS, Quinn TP, Roberts SB
Senescence varies considerably among fishes, and understanding the evolutionary basis for this diversity has become an important area of study. For rapidly senescing species such as Pacific salmon, senescence is a complex process as these fish are initiating anorexia while migrating to natal spawning grounds, and die within days of reproduction.
Sensitivity of salmonid freshwater life history in western US streams to future climate conditions.
Glob Chang Biol. 2013 Aug;19(8):2547-56
Authors: Beer WN, Anderson JJ
We projected effects of mid-21st century climate on the early life growth of Chinook salmon (Oncorhynchus tshawytscha) and steelhead (O. mykiss) in western United States streams. Air temperature and snowpack trends projected from observed 20th century trends were used to predict future seasonal stream temperatures.
Riding the crimson tide: mobile terrestrial consumers track phenological variation in spawning of an anadromous fish.

When resources are spatially and temporally variable, consumers can increase their foraging success by moving to track ephemeral feeding opportunities as these shift across the landscape; the best examples derive from herbivore-plant systems, where grazers migrate to capitalize on the seasonal waves of vegetation growth.
The soundscapes of lakes across an urbanization gradient.
PLoS One. 2013;8(2):e55661
Authors: Kuehne LM, Padgham BL, Olden JD
UNLABELLED: BACKGROUND/METHODOLOGY: A significant implication of increasing urbanization is anthropogenic noise pollution. Although noise is strongly associated with disruption of animal communication systems and negative health effects for humans, the study of these consequences at ecologically relevant spatial and temporal scales (termed soundscape ecology) is in early stages of application.
Impacts of ocean acidification on marine seafood.
Trends Ecol Evol. 2013 Mar;28(3):178-86
Authors: Branch TA, DeJoseph BM, Ray LJ, Wagner CA
Ocean acidification is a series of chemical reactions due to increased CO(2) emissions. The resulting lower pH impairs the senses of reef fishes and reduces their survival, and might similarly impact commercially targeted fishes that produce most of the seafood eaten by humans.

Resource competition induces heterogeneity and can increase cohort survivorship: selection-event duration matters.
Oecologia. 2013 Aug 3;
Authors: Gosselin JL, Anderson JJ
Determining when resource competition increases survivorship can reveal processes underlying population dynamics and reinforce the importance of heterogeneity among individuals in conservation. We ran an experiment mimicking the effects of competition in a growing season on survivorship during a selection event (e.g., overwinter starvation, drought).
Injuries from non-retention in gillnet fisheries suppress reproductive maturation in escaped fish.
PLoS One. 2013;8(7):e69615
Authors: Baker MR, Swanson P, Young G
Exploitation of fisheries resources has unintended consequences, not only in the bycatch and discard of non-target organisms, but also in damage to targeted fish that are injured by gear but not landed (non-retention). Delayed mortality due to non-retention represents lost reproductive potential in exploited stocks, while not contributing to harvest.
Identifying preservation and restoration priority areas for desert fishes in an increasingly invaded world.
Environ Manage. 2013 Mar;51(3):631-41
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.
Genomic resource development for shellfish of conservation concern.
Mol Ecol Resour. 2013 Mar;13(2):295-305
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.
