Aim We evaluated how native vegetation cover influences the diversity of arachnid assemblages across multiple spatial scales in major Brazilian ecosystems. Location Brazil (Amazon and Atlantic rainforests, Cerrado savanna and Caatinga dry forest). Taxon Arachnida (Opiliones, Pseudoscorpiones and Scorpiones). Methods We sampled arachnids at 120 sites using active search and litter sifting. Native vegetation cover was quantified...

The precorneal tear film is critical for ocular surface health, and brachycephalic dogs are particularly predisposed to tear film instability due to their unique conformation. This study aimed to establish normative values for tear film parameters in healthy brachycephalic dogs using the OSA-Vet ® , including Schirmer tear test-1 (STT-1), tear meniscus height (TMH), and non-invasive tear breakup time (TBUTNI). Forty brachyceph...

The Asia region harbors exceptional chondrichthyan (shark, ray, and chimaera) diversity but faces intense fishing pressure. The Important Shark and Ray Areas (ISRA) process provides a collaborative, evidence-based framework to identify critical habitats and inform spatial management. We assessed ISRAs across the Bay of Bengal, Southeast Asia, and the Northwest Pacific to characterize their extent, ecological significance, and...

Bees are essential for ecosystem functioning, pollinating many wild and crop plant species. Predicting which species are most vulnerable to global changes, and how their loss may impact ecosystems and human well-being, is critical. Comprehensive information on bee response and effect traits is fundamental to these assessments. However, the Raunkiærian shortfall—insufficient trait data—remains significant for bees, particularly...

Aim Biodiversity shortfalls related to limited knowledge about geographic distribution (Wallacean) and species traits (Raunkiæran) are extremely common in many animal groups and perhaps more evident in invertebrate groups such as spiders. This lack of knowledge could present challenges for researchers investigating the response and effects of spiders along large spatial scales, particularly in the Global South. The aim of the...

Guiana dolphins ( Sotalia guianensis ) are commonly found in shallow waters from South and Central America. From March 2018 to June 2019, boat surveys were conducted to monitor two populations inhabiting the adjacent waters of Ilha Grande Bay and Sepetiba Bay to estimate population abundances and population parameters of apparent survival and capture probability. Photo‐identification was used as a mark‐recapture technique. A t...

Tau is a neuronal protein that confers stability to microtubules; however, its hyperphosphorylation and accumulation can lead to an impairment of protein degradation pathways, such as autophagy. Autophagy is a lysosomal catabolic process responsible for degrading cytosolic components, being essential for cellular homeostasis and survival. In this context, autophagy modulation has been postulated as a possible therapeutic targe...
