Programmed unmanned aerial vehicles show great potential for monitoring marine megafauna in specific areas of interest

Remote Sensing in Ecology and Conservation, Volume 12, Issue 3, Page 368-387, June 2026.
Targeted conservation measures are contingent on robust knowledge of spatio‐temporal animal distribution in areas of interest. We explore unmanned aerial vehicle (UAV) transect monitoring as a novel method for standardized digital aerial surveys of marine megafauna by investigating the fine‐resolution spatio‐temporal distribution of harbour porpoises ...

Whole‐Genome‐Sequencing Reveals Demographic History and Patterns of Parallel Adaptive Evolution in Indo‐Pacific Bottlenose Dolphins (Tursiops aduncus) Across Coastal Australian Seascapes

Molecular Ecology, Volume 35, Issue 11, June 2026.
ABSTRACT Understanding how demographic dynamics interact with environmental heterogeneity is central to explaining patterns of genomic variation in the marine realm. Indo‐Pacific bottlenose dolphins (Tursiops aduncus) occur along most of the Australian coastline, from tropical to temperate waters, encompassing pronounced differences in temperature ...

Modified Endoscopic Removal of Foreign Objects from the Forestomach of a Common Bottlenose Dolphin (Tursiops truncatus) [PDF]

Pakistan Veterinary Journal, 2013
We report on the removal of foreign objects from the forestomach of a 200 kg adult male common bottlenose dolphin (Tursiops truncatus) in the Seoul zoo using a modified stainless steel hook and flexible wire snare attached to a gastrointestinal ...

Genomic Insights Into the Evolutionary History of Berardius Beaked Whales: Speciation Driven by Resource Specialization, Gigantism and Thermal Barriers?

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT Understanding the diversity of our oceans is fundamental now more than ever as climate change and human activities put increasing pressure on marine species and ecosystems. Beaked whales (family Ziphiidae) are among the most poorly understood marine mammals, in part due to their affinity to offshore underwater canyons and prolonged diving ...

Nursing Behavior of Bottlenose Dolphin (Tursiops truncatus) Calves from 1990-2014 at Brookfield Zoo Chicago, USA [PDF]

Animal Behavior and Cognition
While the common bottlenose dolphin (Tursiops truncatus) population under managed care in North American zoos and aquariums is self-sustaining, understanding normal nursing behavior can help management make informed care decisions for neonates and future

Social object play between captive bottlenose and Risso's dolphins.

PLoS ONE, 2018
Many animal species engage in social object play with movable objects. Two bottlenose dolphins (Tursiops truncatus) and one Risso's dolphin (Grampus griseus) owned by the Kujukushima Aquarium, Japan, occasionally shared and played with an object. Herein,

Optimization and validation of a micro–QuEChERS method for phthalates detection in small samples of cetacean blubber

MethodsX
In this study, an innovative method was developed to detect and quantify phthalates in fresh cetacean blubber. An adaptation of the ammonium formate QuEChERS method was used and adapted as a micro-extraction for small quantities of samples. Significantly,

Sighting frequency and relative abundance of bottlenose dolphins (Tursiops truncatus) along the northeast coast of Margarita Island and Los Frailes Archipelago, Venezuela

Revista de Biología Tropical, 2005
The study of local cetaceans in Venezuela has a very recent history, and few efforts have been made in the assessment of coastal populations based on field research.

Assessing fishery interaction on cetaceans stranded along the Italian coastline between 1986 and 2023.

PLoS ONE
Monitoring stranded cetaceans represents a strategic method to assess their health, conservation status, and ecological role in the marine ecosystem. Efficient stranding networks and standardized protocols are essential to monitor this phenomenon and ...
