Relative immunocompetence of the newborn harbour seal, Phoca vitulina.
The immune system of many mammalian species is not fully developed at birth, with newborns obtaining temporary immunological protection from maternal antibodies. Little is known of the immune system of the harbour seal, and developmental aspects of its immune system have not been systematically studied. We collected blood and milk samples from nine free-ranging mother-pup pairs throughout the l...
متن کاملMeticillin-resistant Staphylococcus aureus in a harbour seal (Phoca vitulina).
METICILLIN-resistant Staphylococcus aureus (MRSA) is an important zoonosis that has increased in prevalence over the past decade, with up to 2 per cent of human beings acting as carriers, posing a risk to incontact animals (Tattevin and others 2009, Loeffler and Lloyd 2010, Couto and others 2011). Pulsed-field gel electrophoresis has been used to separate MRSA strains into community-associated ...
متن کاملHydrodynamic determination of the moving direction of an artificial fin by a harbour seal (Phoca vitulina).
Harbour seals can use their vibrissal system to detect and follow hydrodynamic trails left by moving objects. In this study we determined the maximum time after which a harbour seal could indicate the moving direction of an artificial fish tail and analysed the hydrodynamic parameters allowing the discrimination. Hydrodynamic trails were generated using a fin-like paddle moving from left to rig...
متن کاملWhat a jerk: prey engulfment revealed by high-rate, super-cranial accelerometry on a harbour seal (Phoca vitulina).
A key component in understanding the ecological role of marine mammal predators is to identify how and where they capture prey in time and space. Satellite and archival tags on pinnipeds generally only provide diving and position information, and foraging is often inferred to take place in particular shaped dives or when the animal remains in an area for an extended interval. However, fast move...
متن کاملEarlier pupping in harbour seals, Phoca vitulina.
The annual reproductive cycle of most seal species is characterized by a tight synchrony of births. Typically, timing of birth shows little inter-annual variation. Here, however we show that harbour seals Phoca vitulina from the Wadden Sea (southeast North Sea) have shortened their yearly cycle, moving parturition to earlier dates since the early 1970s. Between 1974 and 2009, the birth date of ...
