Gas exchange of captive freely diving grey seals (Halichoerus grypus).
When at sea, phocids dive for long periods and spend a high percentage of their time submerged. This behaviour requires some combination of an increased oxygen storage capacity, rapid oxygen loading at the surface and reduced oxygen utilisation when submerged. To assess these adaptations, breath-by-breath ventilation was studied in four adult grey seals (two male, two female, 160-250 kg), freel...
متن کاملGeographic variation of the major histocompatibility complex in Eastern Atlantic grey seals (Halichoerus grypus).
Pathogen-driven balancing selection maintains high genetic diversity in many vertebrates, particularly in the major histocompatibility complex (MHC) immune system gene family, which is often associated with disease susceptibility. In large natural populations where subpopulations face different pathogen pressures, the MHC should show greater genetic differentiation within a species than neutral...
متن کاملIn-Air Evoked Potential Audiometry of Grey Seals (Halichoerus grypus) from the North and Baltic Seas
In-air anthropogenic sound has the potential to affect grey seal (Halichoerus grypus) behaviour and interfere with acoustic communication. In this study, a new method was used to deliver acoustic signals to grey seals as part of an in-air hearing assessment. Using in-ear headphones with adapted ear inserts allowed for the measurement of auditory brainstem responses (ABR) on sedated grey seals e...
متن کاملPrevalence of morbillivirus antibodies in Scottish harbour seals.
SINCE May 2002, a new outbreak of phocine distemper virus (PDV) in harbour seals (Phoca vitulina) has been spreading through the North Sea (Harding and others 2002, Jensen and others 2002). By late September 2002, over 17,200 dead harbour seals had been reported dead in European waters (Reineking 2002), approaching the 18,000 deaths resulting from the PDV outbreak in 1988 (Heide-Jørgensen and o...
متن کاملThe conflict between grey seals (Halichoerus grypus) and the Baltic coastal fisheries
There is a problematic interaction going on between grey seals and the small scale coastal fisheries in the Baltic. A large number of seals are by-caught and drowned each year, and the viability of the fishery is threatened by catch losses caused by the seals. Traditional mitigation methods are not sufficient, or have in some cases not been properly evaluated. Available methods of quantifying a...
