Environmental enrichment for Killer whales Orcinus orca at zoological institutions: untried and untested [PDF]
, 2017 Despite a history in zoological institutions stretching back more than 50 years, with associated improvements in husbandry and breeding, the keeping of Killer whales Orcinus orca in zoos and aquariums has become highly controversial.

The Anatomical Record, EarlyView.Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

Identification of alimentary components of Antillean manatee diet in the Northeast of Brazil [PDF]
Biotemas, 2008 The manatees are considered to be opportunist herbivors, consuming a great amount of alimentary items. The aim of the present study was to identify the alimentary components of the diet of Antillean manatees in free life in the northeastern region of ...

The Effects of Intraspecific Variation of Crayfish Behavior on Nutrient Cycling in Aquatic Environments [PDF]
, 2020 Human activities are rapidly altering species traits at a global scale. Yet, there remains a critical need to determine whether trait variation within species affects ecosystem responses to global change. In particular, intraspecific variation in feeding

The Anatomical Record, EarlyView.Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds
The Anatomical Record, EarlyView.Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.
