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.

A note on cetacean distribution in the Indian EEZ and contiguous seas during 2003-07 [PDF]

open access: yes, 2008
Relatively little is known about the distribution of cetaceans in Indian seas due to lack of systematic surveys. For collecting data on species distribution, 35 opportunistic surveys were conducted onboard FORV Sagar Sampada between October 2003 and ...

Shoalwater Bay (dugong) plan of management [PDF]

open access: yes, 1996
The actions set out in this plan will contribute to the development of a broader management regime for dugongs by various management agencies. It will also provide guidelines for conserving the dugong population throughout the broader Shoalwater Bay ...

How is the third jaw joint in whales different? Diverse modes of articulation between the jaws of whales

open access: yesJournal of Anatomy, Volume 247, Issue 6, Page 1224-1240, December 2025.
This study conducts the first comprehensive morphological investigation of the mandibular symphysis in whales. Using gross anatomical observation and CT cross‐sectional data, we describe diverse joint morphologies across 74 extant and fossil cetacean taxa. Toothed whales exhibit unfused, partially fused, or fully fused symphyses.

Global Assessment of Marine Reptiles and Mammals Using a Taxonomic Distinctness Tool: Implications for Their Conservation

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
This study examines the global distribution of marine reptiles and mammals, revealing contrasting biogeographic patterns shaped by their distinct evolutionary histories. Marine mammals exhibit non‐random distributions with elevated taxonomic distinctness in the Arctic and North Pacific, whereas marine reptiles show phylogenetic clustering in tropical ...

Marine mammal bycatch in gillnet and other entangling net fisheries, 1990 to 2011

open access: yesEndangered Species Research, 2013
Since the 1970s the role of fishery bycatch as a factor reducing, or limiting the recovery of, marine mammal populations has been increasingly recognized.

Spatial Insurance of Distinct Ecological Functions

open access: yesEcology Letters, Volume 28, Issue 11, November 2025.
We present a new trait‐based framework to quantify spatial functional insurance of distinct ecological functions amongst ecological communities. We identify communities that disproportionately insure (functional sources) or depend on (functional sinks) neighbour communities.

The Marine Mammal Class II Major Histocompatibility Complex Organization

open access: yesFrontiers in Immunology, 2019
Sirenians share with cetaceans and pinnipeds several convergent traits selected for the aquatic lifestyle. Living in water poses new challenges not only for locomotion and feeding but also for combating new pathogens, which may render the immune system ...
