Media Narratives of Human-Wildlife Conflict: Iberian Orcas and Boats in the Spanish Press

Conservation
The killer whale (Orcinus orca) is a crucial predator in marine ecosystems, affecting prey populations and overall ecosystem health. Since May 2020, Iberian killer whales in the Strait of Gibraltar have interacted unusually with pleasure boats, posing ...

A long postreproductive life span is a shared trait among genetically distinct killer whale populations

Ecology and Evolution, 2021
The extended female postreproductive life span found in humans and some toothed whales remains an evolutionary puzzle. Theory predicts demographic patterns resulting in increased female relatedness with age (kinship dynamics) can select for a prolonged ...

Chilean Dolphins (Cephalorhynchus eutropia) Produce Both Narrowband High‐Frequency and Broadband Clicks

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Most dolphin species produce broadband biosonar clicks for echolocating prey, and whistles and burst‐pulsed calls for communication purposes. Seven dolphin species were previously reported to only produce clicks of a narrowband high‐frequency (NBHF) type, very similar to the clicks produced by porpoises.

Using Aerial Photogrammetry to Estimate Body Condition and Assess Sexual Dimorphism in Narwhals

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The Arctic is warming rapidly, impacting ice‐dependent species and communities that rely on them for resources. Body condition indices (BCI) are widely used to assess individual health within populations. We adapted the methodology to improve accessibility for estimating narwhal body condition from drone footage, using body length, body width,

Characterizing Habitat Suitability of Long‐Finned Pilot Whales in a Key Conservation Region of the Southern Iberian Peninsula Using Satellite Tracking Data

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The waters surrounding the southern Iberian Peninsula are a key conservation area for the long‐finned pilot whale (Globicephala melas melas), particularly in the pelagic regions of the Strait of Gibraltar, the Alboran Sea, and the Gulf of Vera, where upwelling, complex bathymetry and frontal dynamics enhance productivity and prey availability,
