Marine 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.

Correcting Lipid Extraction Effects on Nitrogen Isotopic Values (δ15N) in Cetacean Skin
Marine Mammal Science, Volume 42, Issue 2, April 2026.ABSTRACT Stable isotopes of carbon (δ13C) and nitrogen (δ15N) are widely used to study the feeding ecology of cetaceans, as they provide critical insights into diet and migratory behaviors. Lipids in tissues may bias the interpretation of δ13C. Because of this, lipids need to be extracted before measuring stable isotope ratios, but their removal may ...

Applying the Ecological Trap Concept to Cetaceans
Marine Mammal Science, Volume 42, Issue 2, April 2026.ABSTRACT Wild animals may select poor‐quality habitats due to mismatches between perceived and actual habitat quality, creating ecological traps. Although well explored in terrestrial systems, this concept remains underutilized for marine species.

Population Demographics of Killer Whales (Orcinus orca) in Western Australia
Marine Mammal Science, Volume 42, Issue 2, April 2026.ABSTRACT Understanding population demographics is crucial for the effective conservation of species. This is particularly important for apex predators, such as the killer whale (Orcinus orca), which play important roles in maintaining the structure and function of ecosystems. In this study, we used capture‐mark‐recapture (CMR) modeling to assess killer

Marine 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 ...

Marine Mammal Science, Volume 42, Issue 2, April 2026.ABSTRACT The franciscana dolphin (Pontoporia blainvillei) is a threatened cetacean whose northernmost population (Franciscana Management Area Ia)—part of the recently described subspecies P. b. pukusi—faces significant anthropogenic pressures, including impacts from a major mining dam collapse.

Marine Mammal Science, Volume 42, Issue 2, April 2026.ABSTRACT Sperm whales (Physeter macrocephalus) play an important role in marine ecosystems as top predators, nutrient vectors, and indicators of ecosystem health. In Aotearoa New Zealand, sperm whales remain largely understudied other than at Kaikōura, a foraging area for males.

Marine Mammal Science, Volume 42, Issue 2, April 2026.ABSTRACT Modeling a species' ecology and abundance provides important insights into its habitat preferences, population trends, and distribution. Here, we studied how environmental factors relate to common dolphin (Delphinus delphis) density in waters off mainland Portugal.

Transposon Ecology and the Octopus Genome
BioEssays, Volume 48, Issue 3, March 2026.Transposable elements (TEs) are mobile strands of DNA prevalent in octopus genomes. TE activity in the octopus brain might reflect an organism‐beneficial role in cognition; or could be a deleterious byproduct of TE parasitism. Viewing TEs from a genome‐ecology perspective generates novel predictions about differential expression levels across “genomic ...
