Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

Ecological Entomology, EarlyView.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

Who prefers the dark? Daily activity of dung beetles from an Amazonian region

Ecological Entomology, EarlyView.
Daily activity patterns shape how dung beetle species coexist in Amazonian forests, revealing temporal niches that reduce competition and structure biodiversity. We compared species richness, abundance and assemblage composition of dung beetles sampled during day and night in a conserved terra‐firme forest in the Brazilian Amazon. Although richness and

When Similar Individuals Don't Attract: Absence of Assortative Mating by Coloration in a Damselfly With Honest Signaling

Ethology, EarlyView.
In Acanthagrion lancea damselflies, both sexes display blue ornamentation, but do they choose mates based on it? We tested whether mutual mate choice and time constraints influence ornament evolution. Blue coloration correlated with individual quality, but individuals did not choose mates based on color, and this was unaffected by time constraints over

Navigating Narratives: An Exploratory Scoping Review on the Framing of the Illegal, Unreported and Unregulated Fishing Research

Fish and Fisheries, EarlyView.
ABSTRACT Sustainable fisheries are often undermined by illegal, unreported and, in some cases, unregulated fishing (collectively, IUU fishing). As such, it is critical to ensure that current research effectively informs practical fisheries management interventions.

Assessment of Bottom Trawl Impacts on the Status of Seabed Communities in European Seas

Fish and Fisheries, EarlyView.
ABSTRACT Bottom trawling affects seabed habitats, but its large‐scale impacts remain poorly quantified. Assessment of trawling impacts is essential to support monitoring and achieving sustainability objectives under international conventions, sustainable development goals, and seafood certification programs.

TNF‑α Gene Polymorphisms as Determinants of Alloantibody Emergence in Hemophilia: A Systematic Review and Meta‐Analysis

Haemophilia, EarlyView.
ABSTRACT Introduction Inhibitor development remains one of the most serious complications of replacement therapy in patients with hemophilia. Tumour necrosis factor‐alpha (TNF‐α) is a key pro‐inflammatory cytokine, and its genetic variants have been implicated in immune‐related conditions.
