Plasticity in the reproductive biology of Yellowstone cutthroat trout Oncorhynchus virginalis bouvieri in Yellowstone Lake following lake trout Salvelinus namaycush invasion

open access: yesJournal of Fish Biology, EarlyView.
Abstract Yellowstone cutthroat trout Oncorhynchus virginalis bouvieri in Yellowstone Lake are the focus of intensive conservation efforts due to the threat of predation by invasive lake trout Salvelinus namaycush. Suppression gillnetting has reduced the abundance of predatory lake trout, and the Yellowstone cutthroat trout population is recovering ...

Clustering sperm: A statistical approach to identify sperm morph numbers in the Drosophila obscura species group

open access: yesPhysiological Entomology, EarlyView.
Most Drosophila species, such as D. melanogaster, make one type of sperm, while the obscura species group produces multiple sperm morphs, with different total lengths and nuclear lengths. The pseudoobscura species subgroup produces three sperm morphs (one long, two short). This is a derived feature as other sub‐groups produce two sperm morphs.

Ips acuminatus (Gyllenhal) in the Czech Republic: Flight dynamics and adult population structure

open access: yesPhysiological Entomology, EarlyView.
Ips acuminatus exhibits a univoltine life cycle in Central Europe and no full second generation in midsummer. The sex ratio shifts from male‐biased in spring to slightly female‐biased with the season, with over 90% of females mated. Among the pheromone lures tested, the ACP was most attractive, and combining ACP and PH lures could be used for effective

Critical knowledge gaps in the conservation and restoration of cold‐water corals

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Critical knowledge gaps hamper effective conservation of threatened cold‐water coral (CWC) ecosystems, facing cumulative anthropogenic and climate pressures. This review provides a strategic roadmap for urgent, informed intervention.

Evaluation of metabolism‐related molecules in rat model of autism spectrum disorders

open access: yesExperimental Physiology, EarlyView.
Abstract Autism spectrum disorders (ASD) are neurodevelopmental pathologies. Investigating both sexes is crucial for understanding sex‐specific manifestations of ASD. This study aims to examine ASD‐like behaviours and metabolic alterations in male and female rats prenatally exposed to valproic acid (VPA).
