Molecular characterization of a new emaravirus infecting Clerodendrum thomsoniae plantsNARA Subscribed
High-throughput sequencing revealed a new emaravirus named clerodendrum yellow blotch virus (ClYBV), infecting Clerodendrum thomsoniae plants in São Paulo State, Brazil. Four genomic RNA segments (RNA1, RNA3, RNA4, and RNA5) were recovered, whereas RNA2 remained undetected. Phylogenetic analysis and pairwise comparisons based on amino acid sequences showed ClYBV is most closely related to redbud yellow ringspot-associated viru...
The early Middle Miocene (15.9 Ma) site of els Casots (Vallès-Penedès Basin, Catalonia, Spain) has yielded a rich vertebrate assemblage, including abundant carnivoran remains that mostly remain unpublished. Here we describe a new species of the amphicyonid genus Paludocyon based on a compressed cranium with well-preserved teeth and an isolated lower molar (m2) from els Casots. Paludocyon moyasolai sp. nov., included in the sub...
Why Rules Fail: Institutional Roots of Non-Compliance in Mexico’s Small-Scale Shark FisheryOA Marine
Small-scale fisheries management is a critical challenge for global fisheries sustainability. This study diagnoses the institutional failures behind overexploitation and regulatory non-compliance in Mexico’s shark-cazón fishery (predominantly Rhizoprionodon terraenovae). Using the Institutional Analysis and Development (IAD) Framework and Ostrom’s Social-Ecological Systems (SES) approach, we assessed the catch series (1976–201...

Soil Microbial Diversity and Network Organization Respond to Land Use and Agricultural Inputs WorldwideNARA Subscribed
Soil microbiomes are critical for ecosystem functioning, yet the global influences of climate and agricultural practices on their diversity and structure remain incompletely characterized. Here we analyzed 1921 soil samples from 33 countries worldwide across diverse biomes to assess how climate gradients and agricultural inputs, including pesticides and fertilizers, shape prokaryotic and fungal communities. We found that micro...
Understanding the life-history strategies of deep-sea fishes is essential for improving ecological knowledge and informing conservation efforts. Using otolith microchemistry, this study reconstructed the ontogenetic movement patterns of four grenadier species (Nezumia aequalis, Hymenocephalus billsam, Coelorinchus marinii, and Malacocephalus occidentalis) caught in the continental slope off southern Brazil (Southwestern Atlant...
