Gonadal Development–Related Genes and a Male‐Specific Genetic Marker Identified in the Endangered Sichuan Taimen (Hucho bleekeri)

open access: yesIntegrative Zoology, EarlyView.
Integrated transcriptomic and proteomic analyses were used to validate gonadal development–related genes and to identify a sex‐specific molecular marker in Hucho bleekeri. ABSTRACT Sex determination and differentiation represent fundamental topics in reproductive biology. Sichuan taimen (Hucho bleekeri), a first‐class national protected fish species in

Hybridization With a Non‐Native Congener Threatens the Catalan Chub (Squalius laietanus): Optimization of a DNA‐Based Early Warning Tool

open access: yesIntegrative Zoology, EarlyView.
Hybridization with non‐native congeners threatens endemic freshwater fishes. Using a rapid and cost‐effective nuclear DNA assay, we detected widespread hybridization between the Catalan chub (Squalius laietanus) and the non‐native European chub (Squalius cephalus) across S.

Downstream Passage Performance of European Silver Eels (Anguilla anguilla): The Importance of Phenotypic Variation and Rack Design

open access: yesAnimal Conservation, EarlyView.
During their spawning migration, European silver eels frequently encounter hydropower facilities where successful downstream passage is essential for the conservation of this critically endangered species. In this study, we evaluated how three angled rack designs and individual behavioral variation influenced downstream passage success in large‐scale ...

Growth of Oncorhynchus mykiss (Rainbow Trout) through a Recirculation System in the Foothills of the Extreme North of Chile

open access: yesAnimals
Given the overexploitation of fisheries and the growing consumption of sea products, aquaculture is emerging as an alternative to meet the demand for protein at regional, national, and global levels. In northern Chile, the foothills of the Andes offer an

Dispersal, source and glass chemistry of a third tephra unit within Iceland's Settlement Layer

open access: yesBoreas, EarlyView.
Tephra layers may be studied to understand the dynamics and sequence of past explosive volcanism. In Iceland, the distinctive Settlement Layer (AD ~877) underlies almost all archaeological evidence for the Norse Settlement and is preserved in soils across Iceland and as cryptotephra overseas.

Unaccompanied Refugee Adolescents' Experiences With Professional Support During Their Transition to Adulthood

open access: yesChild &Family Social Work, EarlyView.
ABSTRACT The transition to adulthood is a complex period for unaccompanied refugee adolescents, who must navigate this phase without the physical presence of their parentals while adjusting to life in a new country. This longitudinal qualitative study explores how unaccompanied refugee adolescents in the Netherlands experience professional support ...

Mechanistic insights into HapC: A key enzyme in prodiginine biosynthesis in Hahella chejuensis

open access: yesThe FEBS Journal, EarlyView.
HapC catalyzes prodiginine biosynthesis through coordinated movements of its ATP‐binding, substrate‐binding, and catalytic‐swivel domains. The enzyme shows tolerance toward short‐chain MAP analogs, and docking analyses reveal key residues and structural features underlying its substrate flexibility.
