Unveiling Patterns in Cetacean Strandings Along Southern Atlantic Iberia: Temporal and Spatial Trends, Seasonality, and Causes of Death

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT We compiled 46 years of cetacean strandings in the Algarve, Portugal, describing temporal–spatial patterns, size–sex structure, and causes of death (COD). We analyzed national records and years with a dedicated regional stranding network (SN) to assess annual/seasonal trends, spatial hotspots, and compare biometrics and COD.

Bottlenose dolphin habitat and management factors related to activity and distance traveled in zoos and aquariums.

open access: yesPLoS ONE, 2021
High-resolution non-invasive cetacean tagging systems can be used to investigate the influence of habitat characteristics and management factors on behavior by quantifying activity levels and distance traveled by bottlenose dolphins (Tursiops truncatus ...

Establishing death in stranded Odontocetes (toothed whales) using other mammals : a pilot study : a thesis presented in partial fulfillment of the requirements for the degree of Master of Science in Zoology at Massey University [PDF]

open access: yes, 2003
The aim of this study was to investigate and evaluate a new method for determining death in stranded odontocetes (toothed whales). The new method was using the pulsations seen in the retinal blood vessels in the place of the heart rate. The retinal blood

A kinematic study on (un)intentional imitation in bottlenose dolphins [PDF]

open access: yes, 2015
The aim of the present study was to investigate the effect of observing other's movements on subsequent performance in bottlenose dolphins. The imitative ability of non-human animals has intrigued a number of researchers.

Stranding of a Hector's Beaked Whale (Mesoplodon hectori) (Gray 1871) From South Australia Unearths Novel Additional Teeth

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Most extant beaked whales have reduced dentition of one or two pairs of tusk‐like, mandibular teeth that erupt through the gum only in adult males. Additional teeth have been recorded in several species and genera. A juvenile Hector's beaked whale (SAMA M26434) having additional teeth was collected in South Australia and its skeleton and ...

Cetaceans value and conservation in the Mediterranean Sea [PDF]

open access: yes, 2015
This review provides an overview of the Mediterranean diversity and conservation status of cetaceans, and the value associated with their conservation and non-consumptive use. Mediterranean Sea is one of the world's diversity hotspots.

Post‐Release Survival and Behavioral Recovery of a Rehabilitated Short‐Finned Pilot Whale (Globicephala macrorhynchus) in the South China Sea Revealed Through Satellite Tracking

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This study presents the first empirical evidence of successful rehabilitation and post‐release monitoring of a short‐finned pilot whale in the South China Sea—a region where such data are critically lacking despite frequent stranding events. Using satellite telemetry and a dedicated resighting expedition, we documented the 52‐day movement, diving ...

A Multi‐Taxa Approach to Estuarine Biomonitoring: Assessing Vertebrate Biodiversity and Ecological Continuity Using Environmental DNA Metabarcoding in the Rance River (Brittany, France)

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We applied eDNA metabarcoding to assess vertebrate diversity in the Rance Estuary, France, across five stations spanning marine to freshwater environments, including areas upstream and downstream of a tidal power plant dam. A total of 124 vertebrate MOTUs were detected, with community composition reflecting the estuarine gradient and species turnover ...

Age determination and age related factors in the teeth of Western North Atlantic bottlenose dolphins. [PDF]

open access: yes, 1980
Teeth were taken from 120 bottlenose dolphins, Tursiops truncatus, which had stranded on the mid-Atlantic coast of the United States. The number of annual growth layer groups (GLGs) for each animal was used to construct a growth curve. The growth rate of

Passive Acoustic Monitoring Reveals New Insights Into the Acoustic Occurrence and Foraging Activity of Hector's Dolphins in Porpoise Bay, New Zealand

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
To effectively mitigate disturbances from human activities on vulnerable dolphin populations, it is crucial to understand fine‐scale variation in habitat use. This study investigated the habitat utilisation of a small subpopulation of Hector's dolphins (Cephalorhynchus hectori) in Porpoise Bay, New Zealand.
