Early Social Networks Predict Survival in Wild Bottlenose Dolphins
A fundamental question concerning group-living species is what factors influence the evolution of sociality. Although several studies link adult social bonds to fitness, social patterns and relationships are often formed early in life and are also likely to have fitness consequences, particularly in species with lengthy developmental periods, extensive social learning, and early social bond-for...
متن کاملEffects of capture on adrenal steroid and vasopressin concentrations in free-ranging bottlenose dolphins (Tursiops truncatus).
Marine mammals are routinely caught in the wild in an effort to monitor their health. However, capture-associated stress could potentially bias various biochemical parameters used to monitor the health of these wild caught animals. Therefore, the effects of capture were quantified by measuring plasma adrenal steroids and arginine vasopressin (AVP) in free-ranging bottlenose dolphins (Tursiops t...
متن کاملPhenotyping and comparing the immune cell populations of free-ranging Atlantic bottlenose dolphins (Tursiops truncatus) and dolphins under human care
BACKGROUND Studies suggest that free-ranging bottlenose dolphins exhibit a suppressed immune system because of exposure to contaminants or microorganisms. However, due to a lack of commercially available antibodies specific to marine mammal immune cell surface markers, the research has been indecisive. The purpose of this study was to identify cross-reactive terrestrial-specific antibodies in o...
متن کاملEffects of duration of capture and sample handling on critical care blood analytes in free-ranging bottlenose dolphins.
OBJECTIVE To determine effects of duration of capture and sample-handling procedures on blood analytes in free-ranging bottlenose dolphins. DESIGN Cross-sectional study. ANIMALS 154 free-ranging bottlenose dolphins of various ages and both sexes. PROCEDURES Blood samples were drawn from each dolphin within 10 minutes of capture and before release and analyzed by use of a portable analyzer...
متن کاملHigh site fidelity and restricted ranging patterns in southern Australian bottlenose dolphins
Information on site fidelity and ranging patterns of wild animals is critical to understand how they use their environment and guide conservation and management strategies. Delphinids show a wide variety of site fidelity and ranging patterns. Between September 2013 and October 2015, we used boat-based surveys, photographic identification, biopsy sampling, clustering analysis, and geographic inf...
