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...

This work aimed to investigate the distribution and occurrence of fish species along the São Francisco Falso Braço Norte (SFFBN) River basin, a tributary of the Middle Paraná River basin now artificially connected to the Upper Paraná ecoregion, to evaluate how such connectivity may affect the biogeographic distribution and regional composition of freshwater fish species. Quarterly samplings were conducted between August 2022 a...

Introduced species often encounter novel environments that test their capacity for ecological flexibility and adaptation. We investigated ecological niche dynamics in Nanday Parakeets ( Aratinga nenday ), a naturalized parrot species in Los Angeles, to assess whether their introduced range reflects a shift from their native range in South America. Using principal components analysis and niche overlap tests, we found that the i...

This work focuses on the coastal ecosystem of the Gijón bay, located in Asturias, Northern Spain. This bay area is the site of a large, industrialized port and as such its coastal ecosystems are vulnerable to anthropogenic damage due the accumulation Potentially Toxic Elements (PTEs) in marine sediments. To assess the levels of industrial pollution in Gijón’s coastal ecosystem, we collected sediment samples from the three main...

This review analyses 73 peer‐reviewed publications using a combined qualitative and quantitative approach to examine how inequality in small‐scale fisheries is conceptualised, which drivers are most frequently identified, how they manifest, and how proposed interventions address them. The literature shows some conceptual overlap among terms such as ‘inequality’, ‘inequity’, ‘unfairness’ or ‘injustice’, which may reflect both i...

Summary Purpose A series of NDM-producing Escherichia coli ST167 clinical isolates exhibiting resistance to cefiderocol (FDC), with no previous exposure to this antibiotic, were analyzed in this study. Methods The antimicrobial susceptibility testing and phenotypic detection of resistance patterns (Rapid Cefiderocol NP test and MIC determination) were performed for all tested isolates. Their entire genomes were sequenced by us...

Ecosystem functioning is influenced by biological diversity, ecological interactions, and abiotic conditions. Human interactions with ecosystems can cause major changes in how they function when involving changes in the vegetation cover and structure (i.e., land use change). This study examines how land use change affects the diversity of arbuscular mycorrhizal fungi (AMF) and ectomycorrhizal fungi (EMF) in soil and rodent sca...
