Energetic costs of diving and thermal status in European shags (Phalacrocorax aristotelis).
Diving is believed to be very costly in cormorants (Phalacrocoracidae) when compared with other avian divers because of their poor insulation and less-efficient foot propulsion. It was therefore suggested that cormorants might employ a behavioural strategy to reduce daily energy expenditure by minimizing the amount of time spent in water. However, European shags (Phalacrocorax aristotelis) have...
متن کاملFrom cradle to early grave: juvenile mortality in European shags Phalacrocorax aristotelis results from inadequate development of foraging proficiency.
In most long-lived animal species, juveniles survive less well than adults. A potential mechanism is inferior foraging skills but longitudinal studies that follow the development of juvenile foraging are needed to test this. We used miniaturized activity loggers to record daily foraging times of juvenile and adult European shags Phalacrocorax aristotelis from fledging to the following spring. J...
متن کاملNovel Paramyxoviruses in Free-Ranging European Bats
The zoonotic potential of paramyxoviruses is particularly demonstrated by their broad host range like the highly pathogenic Hendra and Nipah viruses originating from bats. But while so far all bat-borne paramyxoviruses have been identified in fruit bats across Africa, Australia, South America, and Asia, we describe the detection and characterization of the first paramyxoviruses in free-ranging ...
متن کاملDevelopmental plasticity of physiology and morphology in diet-restricted European shag nestlings (Phalacrocorax aristotelis).
Growing animals may exhibit developmental plasticity as an adaptation to variability in the environmental conditions during development. We examined physiological and morphological responses to short-term food shortage of 12-16-day-old European shag nestlings kept under laboratory conditions. After 4 days on a weight maintenance diet, the resting metabolic rate (RMR) of diet-restricted nestling...
متن کاملEndoscopy as a new method for sex determination in Siberian sturgeon (Acipenser baerii)
Determination of sex and gonadal development of Siberian sturgeon (Acipenser baerii) by using endoscopy as a new and less aggressive method for sturgeon conservation is the aim of this study. the gonadal development status of 23 Siberian sturgeons (7 years) by using endoscopy and histology for confirmation investigated in Shahid Dr. Beheshti Sturgeon Fish Propagation and Rearing Complex, locate...
