Drivers of Habitat Selection by the Endangered Greater Caribbean Manatee in Coastal‐Marine Ecosystems

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 1, January 2026.
ABSTRACT Habitat selection is a fundamental aspect of animal movement and behaviour, involving strategies that influence population regulation, species interactions, community structure and the generation and preservation of biodiversity. The Greater Caribbean Manatee is a megaherbivorous aquatic mammal with high environmental plasticity, found in a ...

Elephants and Sirenians: A Comparative Review across Related Taxa in Regard to Learned Vocal Behavior

Comparative Cognition & Behavior Reviews, 2022
Vocal production learning is the ability to modify a vocal output in response to auditory experience. It is essential for human speech production and language acquisition. Vocal learning evolved independently several times in vertebrates, indicating evolutionary pressure in favor of this trait. This enables cross-species comparative analysis to be used

Exploring Marine Mammal Cognition as a Conservation Tool

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Cognition is an animal's real‐time adaptation system for responding to change. Rapid environmental change, often anthropogenic, is expanding the range and severity of challenges confronting wild animals. Effective conservation requires a multifaceted approach that includes animals' capacities.

Interaction Between Traditional Fishers and the Neotropical Otter Lontra longicaudis (Olfers, 1818) in a Brazilian Amazon Estuary

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 12, December 2025.
ABSTRACT The neotropical otter Lontra longicaudis (Olfers, 1818) is a semi‐aquatic carnivore from the Mustelidae family with a piscivorous habit that interacts with riverine populations because of fishing resources, and this relationship is often negative, especially in the Amazon where fishing represents an important activity for several communities ...

THE NEOGENE EURO-NORTH AFRICAN SIRENIA: PHYLOGENETIC AND SYSTEMATIC STUDY, PALAEOECOLOGICAL AND PALAEOBIOGEOGRAPHIC CONSIDERATIONS [PDF]

, 2008
The evolution of the Neogene sirenians along the Euro-North African coasts (southern North Sea, northeastern Atlantic, Mediterranean and Paratethys) has been investigated in correlation with the palaeogeographic and palaeoclimatic evolution of the region.

Morphology and function of pinniped necks: The long and short of it

The Anatomical Record, Volume 308, Issue 12, Page 3175-3185, December 2025.
Abstract Terrestrial vertebrates from at least 30 distinct lineages in both extinct and extant clades have returned to aquatic environments. With these transitions came numerous morphological adaptations to accommodate life in water. Relatively little attention has been paid to the cervical region when tracking this transition.

Cranial remain from Tunisia provides new clues for the origin and evolution of Sirenia (Mammalia, Afrotheria) in Africa.

PLoS ONE, 2013
Sea cows (manatees, dugongs) are the only living marine mammals to feed solely on aquatic plants. Unlike whales or dolphins (Cetacea), the earliest evolutionary history of sirenians is poorly documented, and limited to a few fossils including skulls and ...
