Episodic-like memory in common bottlenose dolphins
Current Biology, 2022 Episodic memory involves the conscious recollection of personally experienced events, which has often been argued to be a uniquely human ability.1-5 However, evidence for conscious episodic recall in humans is centered around language-based reports. With no agreed upon non-linguistic behavioral makers of consciousness,6 episodic-like memory7 therefore ...

Cross-modal perception of identity by sound and taste in bottlenose dolphins
Science Advances, 2022 While studies have demonstrated concept formation in animals, only humans are known to label concepts to use them in mental simulations or predictions.

Remote Sensing in Ecology and Conservation, EarlyView.Targeted conservation measures are contingent on robust knowledge of spatio‐temporal animal distribution in areas of interest. We explore unmanned aerial vehicle (UAV) transect monitoring as a novel method for standardized digital aerial surveys of marine megafauna by investigating the fine‐resolution spatio‐temporal distribution of harbour porpoises ...

Social information about others' affective states in a human‐altered world
Journal of Animal Ecology, EarlyView.Faced with anthropogenic change, animals now encounter challenges different from their evolutionary past. To cope with such challenges, animals may use social information about others' affective states to guide their decisions. Considering affective states of wild animals could have important implications for animal welfare and wildlife conservation ...

Interspecies Retinal Diversity and Optic Nerve Anatomy in Odontocetes
Animals, 2023 Throughout evolution, odontocete vision has had to readapt to the aquatic environment, which has had far-reaching effects on ocular anatomy and neurology.

Acoustic behavior of melon-headed whales varies on a diel cycle. [PDF]
, 2015 Many terrestrial and marine species have a diel activity pattern, and their acoustic signaling follows their current behavioral state. Whistles and echolocation clicks on long-term recordings produced by melon-headed whales (Peponocephala electra) at ...

Integrative Zoology, EarlyView.This work aimed to apply the principles of skin mark analysis to a cetacean species to build a sex‐discrimination model exclusively based on photographic material. Relevant differences between sexes emerged in markings, with males presenting more social, aggression‐related, and fishing‐related marks overall, and a stronger tendency of mark accumulation

Integrative Zoology, EarlyView.The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

A remotely operated blood sampling and sedative administration device in freely moving pinnipeds
Methods in Ecology and Evolution, EarlyView.Abstract A remotely operated device for use with freely moving pinnipeds was designed and successfully developed for the collection of blood samples and the administration of sedatives via an indwelling, venous catheter. The performance of the sampler, called the ‘Mossquito’, was demonstrated on six wild caught, young‐of‐the‐year grey seals ...
