Investigating the effects of persistent organic pollutants (POPs) on insulin-like growth factor 1 (IGF-1) in grey seals
… survival and reproductive success.<br/><br/>Grey seals (<i>Halichoerus grypus</i>) are a useful sentinel species to study POPs due to their high fat content, the lipophilic nature of POPs and the high trophic level of the food chain they occupy. Plasma samples from grey seal pups were …

Considering behaviour in genetic sampling – a case study with grey seals
… animals. Buccal swabs were tested in a group of grey seals in a rehabilitation centre. The swabs showed potential for being able to carry out individual genotype analysis to identify polymorphisms; a SNP in the grey seal DRD4 gene not previously reported in any other studies was found. However, …

Characterising fat tissue structure and function in response to hypoxia in grey seals, an animal model of extreme fat deposition and mobilisation, using novel <i>in vivo</i> and <i>in vitro</i> approaches
… initial; background-clip: initial;">Phocid seals go through dramatic seasonal changes in body mass and composition because of the spatial and temporal separation of foraging, reproduction and moulting. The regulation of fat mobilisation during these processes is a key factor for their …
