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.

Effects of graded levels of standard soybean meal on intestinal structure, mucosal enzyme activities, and pancreatic response in Atlantic salmon (Salmo salar L.)

open access: yes, 2003
Duplicate tanks of c.280 g Atlantic salmon (Salmo salar L.) were fed for 60 days on diets in which fishmeal was substituted with graded levels of extracted soybean meal (SBM) comprising 0%, 10%, 15%, 20%, 25% or 35% of total protein.

Integrating Sr isotopes, microchemistry, and genetics to reconstruct Salmonidae species and life history

open access: yesArchaeometry, EarlyView.
Abstract Recent approaches to fisheries research emphasize the importance of the coproduction of knowledge in building resilient and culturally mindful fisheries management frameworks. Despite widespread recognition of the need for Indigenous knowledge and historical reference points as baseline data, archaeological data are rarely included in ...

Scanning Electron Microscopy of the Rainbow Trout (Salmo gairdneri Richardson) Spermatozoon [PDF]

open access: yes, 1976
The scanning electron microscope was used to determine the morphology of the rainbow trout (Salmo gairdneri Richardson) spermatozoon. The spermatozoon is approximately 32 μm long and consists of a head, mitochondrial collar, and flagellum.

A century of theories of balancing selection

open access: yesBiological Reviews, EarlyView.
ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.

Darkling beetles (Alphitobius diaperinus) and their larvae as potential vectors for the transfer of Campylobacter jejuni and Salmonella enterica serovar paratyphi B variant Java between successive broiler flocks [PDF]

open access: yes, 2008
Broiler flocks often become infected with Campylobacter and Salmonella, and the exact contamination routes are still not fully understood. Insects like darkling beetles and their larvae may play a role in transfer of the pathogens between consecutive ...

Contemporary Methods for Capturing Juvenile Salmonids in the Marine Environment

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Anadromous salmonids play vital roles in marine and freshwater ecosystems. The most abundant of these fishes—Pacific salmon (Oncorhynchus spp.)—are integral to coastal ecosystems and communities across the North Pacific Rim, but numerous populations are experiencing dramatic declines, particularly towards the south of their range.

Discovery and characterization of miRNA genes in atlantic salmon (Salmo salar) by use of a deep sequencing approach

open access: yesBMC Genomics, 2013
BackgroundMicroRNAs (miRNAs) are an abundant class of endogenous small RNA molecules that downregulate gene expression at the posttranscriptional level.
