Drone photogrammetry reveals contrasting body conditions of dugongs across the Indo‐Pacific

open access: yesRemote Sensing in Ecology and Conservation, Volume 11, Issue 6, Page 701-718, December 2025.
The monitoring of body condition has gained traction as a way to provide early warning signals of population decline, prompting conservation actions. However, the environmental and anthropogenic drivers of body condition variations are rarely investigated.

Diet of the manatees (Trichechus manatus manatus) in Chetumal Bay, Mexico

open access: yesLatin American Journal of Aquatic Mammals, 2009
Manatees, as well as other sirenians, are aquatic, opportunistic herbivores. Knowledge of their diet is important to determine habitat requirements. This is the first study of manatee diet in Mexico. Our main objective was to identify the plant species eaten by manatees in Chetumal Bay, and to establish if diet composition varied by climatic season ...

Osmoregulation in Wild and Captive West Indian Manatees (Trichechus manatus) [PDF]

open access: yesPhysiological Zoology, 1998
The ability of West Indian manatees (Trichechus manatus latirostris and Trichechus manatus manatus) to inhabit both freshwater and marine habitats presents an interesting model to study osmoregulation in sirenians. Blood samples were analyzed from manatees held in fresh- and saltwater and from wild animals captured in fresh-, brackish, and saltwater ...

Historical Collections of Tropical Marine Mammals Are an Excellent Resource for Ancient DNA

open access: yesMolecular Ecology Resources, Volume 25, Issue 7, October 2025.
ABSTRACT The ability to predict ancient DNA sequencing success in natural history collections is critical to reducing the amount of destructive sampling of a finite resource. So far, studies investigating such success have predominantly focused on taxa with ranges restricted to temperate or cold environments at northern latitudes, which likely aids DNA

Histochemical indications for a chemically complex signal produced by the cervical gill slit gland of the pygmy sperm whale (Kogia breviceps)

open access: yesThe Anatomical Record, Volume 308, Issue 9, Page 2413-2432, September 2025.
Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland
