Evolutionary rescue in a changing world.
Trends Ecol Evol. 2014 Sep;29(9):521-30
Authors: Carlson SM, Cunningham CJ, Westley PA
Evolutionary rescue occurs when adaptive evolutionary change restores positive growth to declining populations and prevents extinction. Here we outline the diagnostic features of evolutionary rescue and distinguish this phenomenon from demographic and genetic rescue. We then synthesize the rapidly accumulating theoretical and experimental studies of evolutionary rescue, highlighting the demographic, genetic, and extrinsic factors that affect the probability of rescue.

Animal attachment to a substrate is very different in terrestrial and aquatic environments. We discuss variations in both the forces acting to detach animals and forces of attachment. While in a terrestrial environment gravity is commonly understood as the most important detachment force, under submerged conditions gravity is nearly balanced out by buoyancy and therefore matters little.
Prof. Julian Olden and SAFS research scientist Lauren Kuehne published an opinion article in the Proceedings of the National Academy of Sciences, titled Lay Summaries needed to enhance science communication. This piece promotes the requirement and publication of lay summaries with peer-reviewed research articles.Read more
Phenotype flexibility in wild fish: Dolly Varden regulate assimilative capacity to capitalize on annual pulsed subsidies.
J Anim Ecol. 2013 Sep;82(5):966-75
Authors: Armstrong JB, Bond MH
1. Large digestive organs increase rates of energy gain when food is plentiful but are costly to maintain and increase rates of energy loss when food is scarce. The physiological adaptations to this trade-off differ depending on the scale and predictability of variation in food abundance.
Incentivizing the Public to Support Invasive Species Management: Eurasian Milfoil Reduces Lakefront Property Values.
PLoS One. 2014;9(10):e110458
Authors: Olden JD, Tamayo M
Economic evaluations of invasive species are essential for providing comprehensive assessments of the benefits and costs of publicly-funded management activities, yet many previous investigations have focused narrowly on expenditures to control spread and infestation. We use hedonic modeling to evaluate the economic effects of Eurasian milfoil (Myriophyllum spicatum) invasions on lakefront property values of single-family homes in an urban-suburban landscape.
Spatial Segregation in Eastern North Pacific Skate Assemblages.
PLoS One. 2014;9(10):e109907
Authors: Bizzarro JJ, Broms KM, Logsdon MG, Ebert DA, Yoklavich MM, Kuhnz LA, Summers AP
Skates (Rajiformes: Rajoidei) are common mesopredators in marine benthic communities. The spatial associations of individual species and the structure of assemblages are of considerable importance for effective monitoring and management of exploited skate populations.

Abstract. Economic evaluations of invasive species are essential for providing comprehensive assessments of the benefits and costs of publicly-funded management activities, yet many previous investigations have focused narrowly on expenditures to control spread and infestation.
Signals of heterogeneous selection at an MHC locus in geographically proximate ecotypes of sockeye salmon.
Mol Ecol. 2014 Oct 5;
Authors: Larson WA, Seeb JE, Dann TH, Schindler DE, Seeb LW
The genes of the major histocompatibility complex (MHC) are an important component of the vertebrate immune system and can provide insights into the role of pathogen-mediated selection in wild populations.
Growth and survival of pacific coho salmon smolts exposed as juveniles to pesticides within urban streams in western Washington, USA.
Environ Toxicol Chem. 2014 Jul;33(7):1596-606
Authors: King KA, Grue CE, Grassley JM, Fisk RJ, Conquest LL
Pesticides are frequently detected in urban streams, with concentrations often exceeding those reported in surface waters within agricultural areas. The authors studied growth, survival, and return rates of coho salmon (Oncorhynchus kisutch) smolts exposed to a pesticide mixture (“cocktail”) representative of the pesticides most frequently reported within urban streams in western Washington State, USA, in fall through early spring.
