Engineered Gravel Trench Hyporheic Exchange to Create Cold‐Water Thermal Refuges

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Warming rivers are driving a loss or fragmentation of cold‐water habitat and providing the impetus to develop proactive thermal management approaches to maintain suitable habitat in rivers. One innovative approach is through the creation of cold‐water thermal refuges during periods of thermal stress for aquatic species.

Enumerating Atlantic salmon smolt production in River Vindelälven based on habitat availability and parr densities : consequences of using different density estimation methods [PDF]

open access: yes, 2010
Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats.

Hunting and fishing harvest data collection: a horizon scanning exercise from the French context

open access: yesWildlife Biology, EarlyView.
Legal and societal moves increasingly lead leisure hunting and fishing practitioners to record their harvest. The total number of individuals harvested per population per year is the minimum required information to feed into demographic models and allow science‐based management. Some few schemes record more detailed data, hence allowing better‐informed

Environment-driven reprogramming of gamete DNA methylation occurs during maturation and is transmitted intergenerationally in Atlantic Salmon

open access: yesG3: Genes, Genomes, Genetics, 2021
An epigenetic basis for transgenerational plasticity in animals is widely theorized, but convincing empirical support is limited by taxa-specific differences in the presence and role of epigenetic mechanisms.

Early life exploration behaviour and life‐history loci are colocalized in an adaptive genomic hotspot in Atlantic salmon

open access: yesJournal of Animal Ecology, EarlyView.
The genetic architecture of phenotypic correlations offers insights into how natural selection operates in the wild. Two functional phenotypes in Atlantic salmon, early life exploration and age‐at‐maturity, are correlated at an adaptive genomic hotspot, but through distinct genetic markers (SNPs), ruling out causality.

Water temperature modeling in the Garonne River (France) [PDF]

open access: yes, 2010
Stream water temperature is one of the most important parameters for water quality and ecosystem studies. Temperature can influence many chemical and biological processes and therefore impacts on the living conditions and distribution of aquatic ...

Comparative Analysis of Heat Exposure‐Induced Molecular Changes in Two Turtle Species with Contrasting Thermal Adaptations

open access: yesIntegrative Zoology, EarlyView.
Protein processing in the endoplasmic reticulum is highlighted in response to heat stress in Platysternon megacephalum. Under heat stress, the up‐regulation of genes such as CHOP in protein processing in the endoplasmic reticulum pathway, along with the suppression of energy and lipid metabolism and the up‐regulation of JARID2 expression, leads to ...

Digestibility in selected rainbow trout families and modelling of growth from the specific intake of digestible protein [PDF]

open access: yes, 2008
The experiments aimed to clarify variations in digestibility of dietary nutrients in rainbow trout. Furthermore, the objective was to study how differences in digestibility might be related to growth and feed utilisation at various growth rates.

Relationships Between European Wildcats and Domestic Cats in an Area of Sympatry: Exploring Key Conservation Questions on Hybridization and Disease Transmission

open access: yesAnimal Conservation, EarlyView.
We have found evidence of behavioural barriers for both hybridization and disease transmission between European wildcats and domestic cats. This includes hierarchical interspecies exclusion enforced by wildcats, as well as sexual selection exerted by wildcat females.
