Density and Abundance of Cetaceans in the Eastern Tropical Pacific Based on a Spatial/Temporal Analysis of 1986–2006 Line‐Transect Surveys

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The abundance of cetaceans in the eastern tropical Pacific Ocean (ETP) is estimated using spatial/temporal density modeling and conventional line‐transect approaches. Line‐transect data are analyzed from 10 ship‐based visual sighting surveys from 1986 to 2006 that include 281,000 km of survey effort in a 19.4 million km2 study area.

Long‐Term Fluctuations in Cetacean Occurrence Derived From Whale‐Watching Platforms Off Southwest Gran Canaria: Evaluating Their Potential as an Ecological Indicator

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
Using an 18‐year dataset of whale‐watching observations from Gran Canaria (Canary Islands), we analysed long‐term temporal dynamics of cetacean communities in the subtropical Atlantic. Standardised sightings per unit effort (SPUE) revealed strong seasonal patterns, multi‐year fluctuations and species‐specific responses to environmental variability ...

Radiographic Assessment of Bone Maturation: A Tool to Estimate Sexual Maturity in Common Dolphins (Delphinus delphis)?

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Accurate inference of sexual maturity is fundamental to interpreting marine mammal life histories and population structure. Using Bayesian logistic regression models with a hierarchical ordinal (HOF‐style) parameterisation and canonical analysis of principal coordinates (CAP), we evaluate skeletal metrics in the pectoral flippers of common ...

Life History Parameters of Indian Ocean Humpback Dolphins Sousa plumbea Off KwaZulu‐Natal, South Africa

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT For the effective conservation of coastal cetaceans, such as Indian Ocean humpback dolphin, Sousa plumbea, currently listed as “Endangered” by the International Union for the Conservation of Nature (IUCN), information on its life history is urgently required.

First Record of a Presumed Risso's Dolphin Calf Associated With a Bottlenose Dolphin in the Mediterranean Sea

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
During a survey in June 2025, researchers recorded a presumed Risso's dolphin calf swimming in echelon position within a bottlenose dolphin group off the Catalan coast (north‐eastern Iberian Peninsula). Two possible interpretations are discussed: (1) it may represent the first hybrid calf reported in the Mediterranean, or (2) it may be the first ...

Donnes Nouvelles sur la Frequence de Stenella coeruleoalba dans le Nord-Est Atlantique

open access: yes, 1984
From sightings at the sea, Stenella coeruleoalba has been recorded as far as 50 N. The higher frequency during summer may probably be related to a moving north for the populations.

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.
