Whoriskey, S., Pearson, L. E., Harris, H. S. et al. 2022. Using a combination of midazolam and butorphanol is a safe and effective reversible field sedation protocol for Weddell seal (Leptonychotes weddellii) pups. Vet Record 191(11), e2238.

Background: Weddell seals (Leptonychotes weddellii) are a well-studied species of phocid with an apparent sensitivity to immobilising agents. Mortality as high as 31% has been reported during field immobilisation. This study investigated the use of...

Serres, A., Hao, Y., Wang, D. 2022. Monitoring captive odontocetes’ participation during training sessions for improving training efficiency and welfare evaluation. Journal of Veterinary Behavior 47, 45-58.

In captive facilities, odontocetes are subject to daily training/feeding sessions which often create close relationships between animals and their caretakers. Therefore, such sessions are thought to provide information that can be useful for welfare assessment...

Guérineau, C., Lõoke, M., Ganassin, G. et al. 2022. Enrichment with classical music enhances affiliative behaviours in bottlenose dolphin. Applied Animal Behaviour Science 254, 105696.

Environmental enrichment is a crucial element for the promotion of welfare of animals kept under human care. While a large variety of environmental enrichments has been proposed and studied for terrestrial animals, including a growing...

Probert, R., Bastian, A., Elwen, S. H. et al. 2021. Vocal correlates of arousal in bottlenose dolphins (Tursiops spp.) in human care. PLoS ONE 16(9), e0250913.

Human-controlled regimes can entrain behavioural responses and may impact animal welfare. Therefore, understanding the influence of schedules on animal behaviour can be a valuable tool to improve welfare, however information on behaviour overnight and in...

Lauderdale, L. K., Shorter, K. A., Zhang, D. et al. 2021. Habitat characteristics and animal management factors associated with habitat use by bottlenose dolphins in zoological environments. PLoS ONE 16(8), e0252010.

The way an animal uses its habitat can serve as an indicator of habitat appropriateness for the species and individuals. Bottlenose dolphins (Tursiops truncatus and Tursiops aduncus) in accredited zoos and aquariums experience a range...

Lauderdale, L. K., Mellen, J. D., Walsh, M. T. et al. 2021. Towards understanding the welfare of cetaceans in accredited zoos and aquariums. PLoS ONE 16(8), e0255506.

Cetaceans are long-lived, social species that are valued as ambassadors inspiring the public to engage in conservation action. Under professional care, they are critical partners with the scientific community to understanding the biology, behavior, physiology...

Miller, L. J., Lauderdale, L. K., Bryant, J. L. et al. 2021. Behavioral diversity as a potential positive indicator of animal welfare in bottlenose dolphins. PLoS ONE 16(8), e0253113.

Accredited zoological facilities are committed to fully understanding the behavioral, mental, and physical needs of each species to continuously improve the welfare of the animals under their professional care and detect when welfare has diminished...

Miller, L. J., Lauderdale, L. K., Mellen, J. D. 2021. Relationships between animal management and habitat characteristics with two potential indicators of welfare for bottlenose dolphins under professional care. PLoS ONE 16(8), e0252861.

Accredited zoos and aquariums continually strive to ensure high levels of animal welfare for the animals under their professional care. Best management practices include conducting research to better understand factors that lead to optimal welfare...

Miller, L. J., Lauderdale, L. K., Mellen, J. D. et al. 2021. Assessment of animal management and habitat characteristics associated with social behavior in bottlenose dolphins across zoological facilities. PLoS ONE 16(8), e0253732.

Bottlenose dolphins are a behaviorally complex, social species that display a variety of social behaviors. Because of this, it is important for zoological facilities to strive to ensure animals display species-appropriate levels of social behavior...

Zemanova, M. A. 2021. Noninvasive genetic assessment is an effective wildlife research tool when compared with other approaches. Genes 12(11), 1672.

Wildlife research has been indispensable for increasing our insight into ecosystem functioning as well as for designing effective conservation measures under the currently high rates of biodiversity loss. Genetic and genomic analyses might be able...
