First Comprehensive Study of Telomere Length Measured by Southern Blot Hybridization and Oxidative Stress Across 12 Captive Marine Mammal Species

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Telomeres, repetitive nucleotide sequences at chromosome ends, shorten with oxidative damage and cell replication, and are increasingly used as biomarkers of stress and physiological state. Despite this potential, telomere length (TL) in marine mammals has been measured using Southern blot hybridization in only a few cases, often from ...

Image_2_Dugongs (Dugong dugon) along hyper-urbanized coastlines.tif

, 2022
Coastal development and the increased anthropogenic use of sea spaces have rapidly degraded coastal habitats throughout Southeast Asia. We study how these activities impact dugong (Dugong dugon) population(s) along hyper-urbanized coastlines of the Johor

Deep neural networks based automated extraction of dugong feeding trails from UAV images in the intertidal seagrass beds.

PLoS ONE, 2021
Dugongs (Dugong dugon) are seagrass specialists distributed in shallow coastal waters in tropical and subtropical seas. The area and distribution of the dugongs' feeding trails, which are unvegetated winding tracks left after feeding, have been used as ...

Long-distance oceanic movement of a solitary dugong (Dugong dugon) to the Cocos (Keeling) Islands [PDF]

, 2007
In this paper, we report on the arrival of a small (2 m long) male dugong (Dugong dugon) to the Cocos (Keeling) Islands (12° 12' S, 96° 54' E), Indian Ocean.

Sparse seagrass meadows are critical dugong habitat: A novel rapid assessment of habitat-wildlife associations using paired drone and in-water surveys

Ecological Indicators
Understanding the fine-scale behavioural and feeding ecology of marine megafauna is imperative for effective management of their habitat areas; however, obtaining the relevant data can be both costly and challenging.

Illegal Wildlife Trade in a Tourism and Biodiversity Hotspot

Sustainable Development, Volume 33, Issue 6, Page 9106-9122, December 2025.
ABSTRACT There are clear connections between tourism, development, and sustainable use—particularly in biodiversity hotspots, where tourists may unknowingly purchase souvenirs made from protected wildlife. This issue is explicitly recognized in the Sustainable Development Goals, including SDG15, Life on Land, and SDG16, Peace, Justice, and Strong ...

Integrating Environmental DNA Metabarcoding and Remote Sensing Reveals Known and Novel Fish Diversity Hotspots in a World Heritage Area

Diversity and Distributions, Volume 31, Issue 11, November 2025.
ABSTRACT Aim Shark Bay, a UNESCO World Heritage site in Western Australia, is highly vulnerable to climate change, yet its fish biodiversity remains poorly understood at fine spatial scales. We integrated environmental DNA (eDNA) metabarcoding with high‐resolution remote sensing to assess and extrapolate fish diversity patterns, providing a scalable ...

Long-term occupancy trends in a data-poor dugong population in the Andaman and Nicobar archipelago.

PLoS ONE, 2013
Prioritizing efforts for conserving rare and threatened species with limited past data and lacking population estimates is predicated on robust assessments of their occupancy rates.

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

Molecular 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

Conflicts about Living Marine Resources in Southeast Asian and Australian Waters: Turtles and Dugong as Cases [PDF]

This paper considers conflicts that arise and socioeconomic problems involved in managing fugitive resources, especially transborder or transfrontier ones when economic development occurs.
