Environmental Stress Drives Plasticity in Sexual Bimaturism in the Black Soldier Fly (Hermetia illucens Linnaeus, 1758)

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 736-749, July 2026.
We measured the plasticity in sexual bimaturism (SBM; differences between sexes in the timing of sexual maturity) in the black soldier fly (BSF) by exposing larvae to nutrient availability and humidity stress. Our results show that SBM can range between protandry and protogyny depending on the environmental quality. Additionally, we found the degree of

Environmental Drivers of Jumbo Squid During Fishery Collapse in the Gulf of California (2019–2024)

Fisheries Oceanography, Volume 35, Issue 4, Page 477-491, July 2026.
ABSTRACT The jumbo squid (Dosidicus gigas) is a cephalopod endemic to the eastern Pacific with significant ecological and economic importance. Its exploitation in the Gulf of California (GC) peaked in the 1990s, with catches exceeding 100,000 tons, but collapsed in 2009 and virtually disappeared by 2015, largely due to environmental changes and ...

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

Marine 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 ...

Occurrence and Whistle Characteristics of Small Odontocetes in Two Coastal Regions of the Sea of Japan

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT This study investigated the occurrence and whistle characteristics of small odontocetes in Wakasa Bay and Aso Bay, located in the coastal waters of the Sea of Japan, where ecological data are limited. Passive acoustic monitoring using A‐tag and SoundTrap was conducted from 2022 to 2024, with detections on 8.8% and 12.4% of monitoring days at ...

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

Marine 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

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

Zoologica Scripta, Volume 55, Issue 4, Page 521-544, July 2026.
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,

Mascarene High Variability Shapes the Demography of a Wind‐Reliant Marine Top Predator

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Subtropical anticyclones are semi‐permanent atmospheric high‐pressure systems located in all five major ocean basins and are associated with large‐scale wind and weather patterns. They shape the physical environments of many species, yet their impacts on wildlife remain unexplored. We combined population and climate analyses to investigate the
