Three new isatin–pyridine-2-oxime hybrids (AM01–03) were synthesized and experimentally evaluated as reactivators of acetylcholinesterase (AChE) inhibited by a surrogate of the nerve agent A-242, in comparison with their 4-oxime isomers previously reported by our research group. Furthermore, the interactions of these molecules within the AChE/A-242 complex were assessed through docking and molecular dynamics (MD) simulations....

Atta robusta is a narrow endemic leaf-cutting ant restricted to restinga habitats along Brazil’s southeastern coast. Despite its conservation status, little is known about its evolutionary history and genetic structure. Here, we investigate patterns of genetic variation in A. robusta using mitochondrial (COI–IGS–tRNALeu–COII) and nuclear (EF1alpha copy one) DNA markers sampled across its known range. We assess genetic diversit...

The montado is a traditional agroforestry system in Portugal that combines cork or holm oak trees with pastures and crops. It provides multiple ecosystems services and supports rural livelihoods. However, in recent decades, the montado has faced several threats that have caused its decline and degradation. Here, we analyse the recent changes in montado cover—between 2006 and 2018—and assess the main drivers and processes of ch...

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...

Aim We investigated how local‐scale environmental heterogeneity influences biodiversity patterns across broad biogeographic gradients, using intertidal microhabitats as a model system within one of the most environmentally stressful ecosystems on Earth. Location Intertidal habitats at 26 locations (two rocky shore sites per location) across six continents, spanning 98° of latitude (38°S to 60°N). Time Period 2019–2022. Major T...

This study investigated copper accumulation and pesticide residue patterns in agricultural soils under four cropping systems (stone fruit, olive, grapevine and potato) in Zadar County, Croatia. Soil samples were taken before and after the growing season. Copper concentrations were determined by ICP-MS after microwave digestion. A total of 453 pesticide-active compounds were analyzed using available standards by LC–MS/MS and GC...

In recent years, there has been an increasing need for climate information across diverse sectors of society. This demand has arisen from the necessity to adapt to and mitigate the impacts of climate variability and change. Likewise, this period has seen a significant increase in our understanding of the physical processes and mechanisms that drive precipitation and its variability across different regions of Africa. By levera...

Identifying the drivers and ecological mechanisms that shape species occupancy patterns at large scales is decisive in understanding how species respond to environmental changes. In this study, we compiled camera trapping data from different scientific projects and monitoring programs to conduct the first assessment of the relevant ecological drivers of red fox ( Vulpes vulpes ) occupancy patterns at the national level in Port...
