Hybridization between genetically modified Atlantic salmon and wild brown trout reveals novel ecological interactions

Abstract
Interspecific hybridization is a route for transgenes from genetically modified (GM) animals to invade wild populations, yet the ecological effects and potential risks that may emerge from such hybridization are unknown.

Characterization of genes involved in ceramide metabolism in the Pacific oyster (Crassostrea gigas).
BMC Res Notes. 2012;5:502
Authors: Timmins-Schiffman E, Roberts S
Abstract
BACKGROUND: The lipid signaling molecule, ceramide, is a key component of the vertebrate stress response, however, there is limited information concerning its role in invertebrate species. In order to identify genes involved in ceramide metabolism in bivalve molluscs, Pacific oyster genomic resources were examined for genes associated with ceramide metabolism and signaling.

Can variation in prey density drive changes in predatory selection in natural systems? For salmon and brown bears, yes

Curry J. Cunningham, Gregory T. Ruggerone, and Thomas P. Quinn
How does the availability of food affect the selectivity of the consumer? It has long been known that survival of prey can depend on their density, as predators become satiated or cannot catch them all. In addition, many studies have shown that predators are selective, tending to kill and consume some species or sizes of prey over others, but very few are examples of prey density driving patterns of selection by predators.

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
Abstract
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.

Putative phage hyperparasite in the rickettsial pathogen of abalone, “Candidatus Xenohaliotis californiensis”.
Microb Ecol. 2012 Nov;64(4):1064-72
Authors: Friedman CS, Crosson LM
Abstract
Studies on the ecology of microbial parasites and their hosts are predicated on understanding the assemblage of and relationship among the species present. Changes in organismal morphology and physiology can have profound effects on host-parasite interactions and associated microbial community structure.

Sensitivity of salmonid freshwater life history in Western US streams to future climate conditions.

Sensitivity of salmonid freshwater life history in Western US streams to future climate conditions.
Glob Chang Biol. 2013 May 2;
Authors: Beer WN, Anderson JJ
Abstract
We projected effects of mid-21(st) 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 climate models and observed 20(th) century trends were used to predict future seasonal stream temperatures.

Evidence for an Amoeba-Like Infectious Stage of Ichthyophonus sp. and Description of a Circulating Blood Stage: A Probable Mechanism for Dispersal Within the Fish Host

Evidence for an Amoeba-Like Infectious Stage of Ichthyophonus sp. and Description of a Circulating Blood Stage: A Probable Mechanism for Dispersal Within the Fish Host
Author(s): Richard Kocan , Scott LaPatra , and Paul Hershberger
Source: Journal of Parasitology, 99(2):235-240. 2013.
Published By: American Society of Parasitologists
DOI: http://dx.doi.org/10.1645/GE-3255.1
URL: http://www.bioone.org/doi/full/10.1645/GE-3255.1
Abstract
Small amoeboid cells, believed to be the infectious stage of Ichthyophonus sp., were observed in the bolus (stomach contents) and tunica propria (stomach wall) of Pacific staghorn sculpins and rainbow trout shortly after they ingested Ichthyophonus sp.–infected tissues.

Opportunistic exploitation: an overlooked pathway to extinction.

Opportunistic exploitation: an overlooked pathway to extinction.
Trends Ecol Evol. 2013 Apr 4;
Authors: Branch TA, Lobo AS, Purcell SW
Abstract
How can species be exploited economically to extinction? Past single-species hypotheses examining the economic plausibility of exploiting rare species have argued that the escalating value of rarity allows extinction to be profitable. We describe an alternative pathway toward extinction in multispecies exploitation systems, termed ‘opportunistic exploitation’.
