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...
Environmental predictors of fish assemblages in insular streams of the eastern AmazonNARA Subscribed
Understanding fish species distributions remains a key challenge in ecology, particularly in complex environments such as small Amazonian streams. These data are essential for developing and supporting effective management and conservation strategies, especially in highly diverse regions like the Amazon Basin, where substantial gaps in biodiversity knowledge persist. We assessed the structure and composition of fish assemblage...
Knowing with the river: Situated risks of riverine communities in the Peruvian AmazonNARA Subscribed
Dominant approaches to drought and flood risk often marginalize the social and temporal dimensions of how communities experience environmental change. This study explores how three riverine communities in the Peruvian Amazon—Bajo Belén, Tamshiyacu, and El Chino—generate and act on knowledge of river dynamics to sustain livelihoods amid increasing hydrological variability. Using storytelling with 45 participants (2023–2024), an...
Long-term soil health and microbiome responses to sustainable management under drought stress in tropical coffee agroecosystemsNARA Subscribed
Background and aims Implementing sustainable crop management to improve soil health can bolster plant and soil resistance to drought stress. This study evaluated the long-term impact of sustainable soil management on soil health in tropical coffee agroecosystems, focusing on how these practices influenced plant yield and quality, as well as soil microbiome composition and function under drought treatment. Methods Plots were se...
Phosphorus and base cations drive contrasting root dynamics in a central Amazon forestNARA Subscribed
Background and aims In highly weathered soils of central Amazonia, where nutrients such as phosphorus (P) and base cations are scarce, fertilization experiments have demonstrated above- and belowground effects on total net primary productivity (NPP). This study examined how fine root stocks and turnover responded to added nutrients over a two-year period. We predicted that adding a limiting nutrient would decrease fine root st...
Extreme Droughts Push Heterotrophic Functions Above Baseline Levels in a Neotropical EcosystemNARA Subscribed
Droughts are intensifying in the humid Neotropics, raising concerns about the impacts on ecosystem processes related to C cycling, such as decomposition and CO 2 respiration. In particular, the resilience of multiple functions to extreme droughts in Neotropical aquatic systems remains poorly understood, limiting our ability to predict drought‐driven feedbacks on C cycling. Here, we used rain shelters placed above tank bromelia...
In 2023, more than half of olive harvests ( Olea europaea ) across Spain, Greece, and Türkiye were lost to drought. The same year late freeze destroyed 90% of the peach crop ( Prunus persica ) on the Georgia Piedmont and the apple crop ( Malus domestica ) in central New York, Vermont, and southern Quebec. Climate extremes now rank with the costliest threats to agriculture, but their role in forest recovery from diebacks that a...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Functional diversity of Brazilian bees: revealing the unique patterns of the NeotropicsNARA Subscribed
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 African freshwater fishes serve as important biogeographical indicators of geomorphological and hydrological history across the continent. However, research focusing on the phylogeny, biogeography and diversification of African fishes, particularly in central Africa, is relatively scarce. Here, we evaluate three geological hypotheses regarding the formation of the contemporary Congo basin: (1) the dominance of the Ogooué a...
Prof Stephen P. Long, FRS (1950–2025)NARA Subscribed
In the United States, shark meat is sold in grocery stores, seafood markets, and online. The meat is often mislabeled as another species or generically labeled as “shark”. The ambiguity of these generic labels makes it challenging to assess the conservation implications of this practice and for consumers to avoid high trophic-level species that often have high mercury concentrations in their tissues. We purchased and DNA barco...
Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α‐diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e., γ‐diversity), either due to reduced β‐diversity amplifying diversity loss or increased β‐diversity dampening diversity loss. Additionally, studies often focus on taxo...
