Haul-out behaviour, site fidelity and vigilance of common seals (Phoca vitulina) and grey seals (Halichoerus grypus) in the tees Estuary
No full textThe project was carried out from the beginning of May to the beginning of July 1994, at Seal Sands, in the Tees estuary. The study aimed to examine (i) ecological and (ii) behavioural aspects of two species of seals, common seals (Phoca vitulina) and grey seals (Halichoerus grypus). The aims of the study were (i): (a) to document the seasonal fluctuation in number of seals using haul-out sites during May and June, (b) To compare activities between day and night time, (c) To examine possible factors influencing the proportion of the Tees population of common and grey seals hauling-out at Seal Sands, and factors conditioning haul- out site choice, (ii): (a) To examine distribution on haul-out sites and haul-out site fidelity, group and individual behaviour, (b) To determine vigilance behaviour in common and grey seals in relation to time of the day and group size. The number of seals hauled-out at Seal Sands, varied from day to day and night to night, and between successive low tides. The common seal number hauling-out, varied from a minimum of 13 to a maximum of 39, at day time, and from 9 to 15 at night time, these number increased gradually during the study period. The number of grey seals varied from nil on two occasions to 27 at daytime, and from 2 to 26 at night time. Both high and low number of common and grey seals tended to occur on the same days. The number of animals hauling out could be influenced by both environmental factors and population size at Teesmouth. Numbers of common seals at site C during day time was significantly and inversely related to the tide level at low water. The numbers of grey seals at site C at night time were inversely related to wind speed and positively related to maximum temperature. The changes in sites use are discussed in relation to physical characteristics of the sites and tide levels. Common and grey seals were observed to haul-out in restricted areas, although space availability was not a limiting factor. Common seals showed site fidelity both as individuals and as a group. Grey seals, show site fidelity as a group. Vigilance behaviour varied considerably within the two species of seals. In relation to the time of the day, the percentage of common seals alert, tended to decrease progressively after low tide. The percentage of grey seals alert was lower than in common seals with few peaks caused by sudden disturbance. Common seals show a strong negative correlation between the percentage of individuals alert and group size, whereas grey seals did not show any relation to the size of the group
Grey seals (Halichoerus grypus) in the Dutch North sea: population ecology and effects of wind farms
No full textThis study was setup to gain an understanding of the possible effects of large-scale development of wind farms in Dutch waters on grey seals (Halichoerus grypus). This should be considered a first step in doing so as up until now relatively little was known about the species in Dutch waters. The study was carried out in the framework of WE@SEA a foundation aimed at acquiring knowledge in the field of offshore wind energy

The pathology and occurrence of pathogens in Scottish grey seals (Halichoerus grypus).
No full textNeonatal mortality in grey seals on the Isle of May breeding colony and in a rehabilitation centre were investigated by detailed systematic post-mortem examinations (n=59), on-site bacteriology and advanced molecular diagnostic techniques for specific pathogens. Causes of death on the breeding colony included starvation (30%), omphalitis-peritonitis (26%), septicaemia (22%), stillbirth (10%) and trauma (4%) and in the rehabilitation centre starvation (44%) and septicaemia (22%). Detailed key gross and histopathological findings and pathogens are described and include the first report of Listeria monocytogenes in any marine mammal.
Phocid herpes virus 1 nucleic acids were detected in nasal swabs of 58% live, free-ranging grey seal pups (n=90) and 28% yearlings (n=19), suggesting recrudescence in the latter. Previously undetected in Scotland, phocid herpes virus 2 nucleic acids were identified only in yearlings (15%); sealpox was detected in a single live stranded grey seal pup and phocine distemper virus was not detected.
Given their unique characteristics and potential for acting as sentinels of coastal marine health several pathogens of putative anthropogenic origin were investigated: Toxoplasma gondii, Neospora caninum, Salmonella spp. and Campylobacter spp. Toxoplasma gondii DNA was detected in 6% dead free-ranging grey seal pups (n=50) but N. caninum was not found. Salmonella (20%) and Campylobacter (50%) were isolated from rectal swabs of live and dead grey seal pups and Campylobacter was significantly associated with moderate to severe colitis implying pathogenicity. These findings imply a land-sea-land transfer of T. gondii and early exposure of pups to this parasite. Extensive genetic fingerprinting suggested an exchange of Salmonella between grey seal, cattle and human populations and that the Campylobacter isolates may share the same origin as human clinical isolates.
This work provides a solid base line study of diseases present in grey seal pups and demonstrates that they are useful indicators of coastal marine microbial contamination
Heritability and Linkage Analysis of Appendicitis Utilizing Age at Onset
No full textAppendicitis usually afflicts the young, but there is a large tail in the distribution of onset age. The genetics of this disease are still not well understood. A heritability analysis and genome wide linkage analysis of a large twin dataset was undertaken. Treating age of onset of appendicitis as a censored survival trait revealed a heritability of 0.21, and found evidence of linkage to Chromosome 1p37.3.
