This study assesses whether the effective number of breeders ( N b ) can be estimated using a time and cost‐effective protocol using genetic sibship reconstruction from a single sample of young‐of‐the‐year (YOY) for the purposes of Atlantic salmon Salmo salar population monitoring. N b was estimated for 10 consecutive reproductive seasons for S. salar in the River Nivelle, a small population located at the rear‐edge of the spe...

Sustainable forest restoration and management practices require a thorough understanding of the influence that habitat fragmentation has on the processes shaping genetic variation and its distribution in tree populations. We quantified genetic variation at isozyme markers and chloroplast DNA (cpDNA), analysed by polymerase chain reaction–restriction fragment length polymorphism (PCR‐RFLP) in severely fragmented populations of...
