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

Fisheries Oceanography, EarlyView.
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 ...

A new species of jewel‐babbler (Cinclosomatidae: Ptilorrhoa) from the Southern Fold Mountains of Papua New Guinea

Ibis, EarlyView.
Based on distinctive morphological and vocal characters we describe a new species of jewel‐babbler (genus Ptilorrhoa) from the forested karst of the Southern Fold Mountains in Papua New Guinea. The description is based on camera trap data and is presented in accordance with ICZN Declaration 45.

Exploring drivers and costs of partial trans‐Saharan migration in juvenile vultures

Ibis, EarlyView.
Partial migration occurs when only a subset of individuals within a population undertakes a migratory journey. The decision to migrate can be influenced by intrinsic traits (e.g. sex or physical condition) as well as by extrinsic factors (e.g. social environment or resource availability).

Genome and transcriptome‐based identification and expression profiling of chemosensory gene families across developmental stages and tissues in Sirex noctilio (Hymenoptera: Siricidae)

Insect Molecular Biology, EarlyView.
The first draft genome of Sirex noctilio was produced. Fifteen S. noctilio transcriptomes were sequenced to study chemosensory gene expression patterns. SnocOR16 and SnocSNMP1 displayed tissue‐ and sex‐specific expression patterns. Abstract The Sirex woodwasp (Sirex noctilio; Hymenoptera: Siricidae) is among the most destructive invasive pests ...

Wing morphology changes with habitat availability and elevation in an alpine-specialist bird

Global Ecology and Conservation
Intraspecific morphological variation of organisms is known to be influenced by several factors, but the role of habitat availability has been scarcely investigated.

Do Laboratory‐Reared Flies Perform Differently as Pollinators? Morphology, Behaviour and Pollination Performance of Eristalis tenax (Syrphidae)

Journal of Applied Entomology, EarlyView.
ABSTRACT Flies (Diptera) are important pollinators in global agriculture, yet little is known about how intraspecific trait variation influences their pollination performance. We compared morphological traits, foraging behaviour and pollination‐related performance metrics between laboratory‐reared (hereafter lab‐reared) and wild populations of ...

Elevation, rather than land use, causes important dietary shifts in the Mediterranean golden eagle

Journal of Zoology, EarlyView.
In an ever‐changing landscape, golden eagles in the Iberian Peninsula demonstrate remarkable dietary adaptability. We monitored 50 distinct breeding events over 4 years using camera traps, collecting over 520 000 images. Elevation, rather than land use, emerged as the main driver of prey composition: lagomorphs and columbiforms dominated at lower ...

The Ultramorphology and Sexual Dimorphism of Antennae and Sensilla in the Pale Grass Blue, Pseudozizeeria maha (Lepidoptera: Lycaenidae)

Insects
The pale grass blue, Pseudozizeeria maha, is a small lycaenid butterfly widely distributed across Asia. Due to its exclusively diurnal lifestyle and conspicuous sexual dimorphism in wing coloration, vision has traditionally been regarded as the primary ...

Postembryonic development of the predatory strike mechanics in a praying mantis (Insecta: Mantodea)

Physiological Entomology, EarlyView.
Praying mantis forelegs capture prey using specific kinematic and kinetic traits that change in size and morphology during postembryonic growth and sexual dimorphism influences these dynamics. Strike forces grow hyperallometrically with body weight; larger mantises show longer strike durations, slower joint angular velocities and increased tibia ...

Reconceptualizing Gender Transitioning: Recognition, Flexibility, and Safety in Nonbinary Identity Journeys

Sociological Inquiry, EarlyView.
This article interrogates gender transitioning by centering nonbinary experiences, which challenge the binary‐driven narratives that dominate both medical and sociological frameworks of transition. Drawing on seven focus groups with 48 nonbinary participants across multiple countries, this study explores three interrelated forms of transition: social ...
