Advancing Marine Bioacoustics With Deep Generative Models: A Hybrid Augmentation Strategy for Southern Resident Killer Whale Detection

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Automated detection and classification of marine mammal vocalizations is critical for conservation and management efforts but is hindered by limited annotated datasets and the acoustic complexity of real‐world marine environments. Data augmentation has proven to be an effective strategy to address this limitation by increasing dataset ...

Genetic and Ecological Divergence Between Northwest Atlantic Killer Whale Populations. [PDF]

open access: yesEcol Evol
Killer whale (Orcinus orca) populations exhibit substantial genetic, ecological, and morphological differences across their global distribution. In this study, we use whole‐genome resequencing and compound‐specific stable isotope analysis of amino acids to show concurrent genetic and ecological differentiation in two relatively understudied killer ...

Killer Whales in the Central Tropical Pacific: Occurrence, Resightings, Morphology, and Acoustics

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Compared to their well‐studied coastal temperate counterparts, killer whales (Orcinus orca) in tropical‐subtropical and oceanic areas are under‐documented. We used sighting, photo‐identification, and acoustic data of killer whales in the central tropical Pacific (CTP), collected from multiple platforms between 2002 and 2023, to assess their ...

Foraging Ecology and Fisheries Interactions of Common Bottlenose Dolphins (Tursiops truncatus) Inferred From Strandings in Western Iberian Atlantic Waters

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The common bottlenose dolphin (Tursiops truncatus) is a resident species along the Portuguese mainland coast, yet knowledge of its stranding patterns and feeding ecology is scarce. This study presents a comprehensive assessment of strandings (n = 264, from 1980 to 2019) and feeding ecology based on stomach content analysis (n = 43 from 1997 to

The myth of the metabolic baseline: sleep–wake cycles undermine a foundational assumption in organismal biology

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1491-1510, June 2026.
ABSTRACT Basal and standard metabolic rate (BMR and SMR) are cornerstones of physiological ecology and are assumed to be relatively fixed intrinsic properties of organisms that represent the minimum energy required to sustain life. However, this assumption is conceptually flawed. Many core maintenance processes underlying SMR are temporally partitioned

Genetic architecture of phenological, morphological, and phytochemical traits in Cannabis landraces

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Despite its long history of cultivation and diverse applications, Cannabis sativa remains underexplored at the genomic level, particularly in landrace populations that harbor untapped genetic diversity. In this study, we investigated the genetic architecture of 145 Iranian cannabis landrace accessions, including both male and female plants ...
