This case report describes the advanced critical care, surgical management, and one-year outcome of a free-ranging adult male maned wolf ( Chrysocyon brachyurus ) presenting with severe polytrauma and concomitant renal dioctophymosis. The animal was rescued with a severely contaminated open tibial fracture associated with extensive soft tissue necrosis and active myiasis, rendering limb-sparing procedures unfeasible. A high pe...

Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...

The introduction of exotic tree species with dissimilar leaf habits or distinctive chemical composition into native communities may cause impacts on aquatic organisms, yet the relative influence of leaf habit and geographic origin on those impacts remain poorly understood. In this study, we experimentally explored the ecotoxicological effects of aqueous leaf litter extracts from 15 tree species differing in leaf habit (deciduo...

Background Urban greenspaces have the potential to mitigate urban carbon footprints by storing soil organic carbon (SOC). Different management and plant communities associated with different types of urban greenspaces may hold contrasting SOC, as well as different proportions of particulate (POC) and mineral-associated organic carbon (MAOC). In addition, management could outweigh the effects of climate or soil properties as dr...

This study aimed to evaluate the virulence and infection response of Campylobacter jejuni (CJ) strains isolated from chickens, as well as a standard strain isolated from humans, to understand better the pathogen-host relationship between CJ and chicken embryos (CE) with an active immune system. With its well-developed vascular structures, the CE model offers a valuable method for studying complex biological systems. We assesse...

Metamorphosis is a critical bottleneck in the bivalve life cycle, usually associated with high mortality and asynchronous development under hatchery conditions. Synthetic chemical inducers are widely used to overcome these constraints. The neuroactive compounds epinephrine (EPI) and γ-aminobutyric acid (GABA) have been reported to be effective metamorphosis inducers in bivalve species. This study evaluated the inductive effici...

Introduction The microbiome is crucial for the health and resilience of marine species; however, in most cases its complexity and host-specific dynamics remain poorly understood. Methods This study provides a multi-year and multi-seasonal analysis of eukaryotic and prokaryotic microbiomes in three ecologically important bivalves - mussels ( Mytilus galloprovincialis ), clams ( Ruditapes philippinarum ), and cockles ( Cerastode...
