What are the main factors associated with the stranding of the two seal species? What are the factors influencing the prevalence of disease in the two species? Which human-related factors influence the populations of the two seal species?
|Looptijd||2008 - 2015|
The research focuses on the population biology of common seals ( Phoca vitulina) and grey seals ( Halichoerus grypus) in Dutch waters and the identification of human influences affecting these populations.
This PhD is based on research conducted in the period 2006-2013 at the Seal Rehabilitation and Research Centre (SRRC, Pieterburen, The Netherlands) in collaboration with several universities. A multidisciplinary approach has been applied to learn more about the different aspects of the biology and pathology of seals and to be able to obtain a comprehensive view on their status in Dutch waters.
The PhD includes several studies:
- Stranding and pathology,
- Current genetic status of both seal species,
- Parasite infections in young common seals,
- Disturbance as a cause of orphanage,
- The advanced pupping season of common seals.
