BMC Genetics, 2008 Background Winter migration of immature brown trout (Salmo trutta) into freshwater rivers has been hypothesized to result from physiologically stressful combinations of high salinity and low temperature in the sea. Results We sampled brown trout from two

Evidence for adaptive explanations of semelparity in animals
Biological Reviews, EarlyView.ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Pro‐Organic by Design: Choice Architecture Shaping Online Organic Grocery Purchases
Business Strategy and the Environment, EarlyView.ABSTRACT Consumer uptake of organic food is shaped by both personal values and the way choices are structured in the retail environment. Unlike prior research, we here investigate how elements of supermarket choice architecture influence organic choices.

Effect of polyploidization on survival of sea, brook, and rainbow trout hybrids during incubation and early feeding period [PDF]
Acta Ichthyologica et Piscatoria, 1988 Effect of polyploidization on survival of brook trout (Salvelinus fontinalis), sea trout (Salmo trutta morpha trutta) and rainbow trout (Salmo gairdneri) hybrids, including reciprocal crosses, during incubation and larval stages period was tested.

Ecography, EarlyView.Harmful Microcystis proliferation severely threatens aquatic ecosystems globally, but its impacts on food‐web stability remain poorly understood. Here, we analyzed 1309 metagenomic samples from freshwater ecosystems across China to investigate how Microcystis abundance affects synchrony among taxa in multi‐trophic food webs (from bacteriophages to ...

Ecography, EarlyView.Non‐native species introductions profoundly alter freshwater communities, yet the mechanisms by which non‐native fishes affect native community stability remain unclear. Using a multi‐decadal dataset on fish community composition and abundance collected across France, we quantified native community stability and decomposed this metric into its main ...

Osmoregulation in Salmon and Sea Trout Alevins [PDF]
Journal of Experimental Biology, 1982 ABSTRACT Changes in survival, body-water content, body electrolyte concentration and Na+ turnover rates were studied in alevins of Atlantic salmon (Salmo salar L.) and sea trout (Salmo trutta L.) at different developmental stages following exposure to various dilutions of sea water.

Environmental Toxicology and Chemistry, EarlyView.Abstract The EcoToxChip project includes RNA‐sequencing data from experiments involving model (Japanese quail, fathead minnow, African clawed frog) and ecological (double‐crested cormorant, rainbow trout, northern leopard frog) species at multiple life stages (whole embryo and adult) exposed to eight chemicals of environmental concern known to perturb ...
