Global patterns of native aluminum-accumulating plants indicate a predominance in tropical regions and specific taxonomic groupsNARA Subscribed
Background and aims Aluminium (Al) toxicity limits plant growth in acidic soils, affecting plant development and survival. However, some species are tolerant to Al, allowing them to grow under these conditions. In this study, we mapped the global distribution and main taxonomic groups of native Al-accumulating plants and analyzed spatial, temporal, and thematic patterns in the scientific literature on the subject. Methods We a...
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...
Sex‐Specific Atlantic Salmon Upstream Passage and Fallback at a Natural Cascade After Dam RemovalNARA Subscribed
In the Boquet River (NY, USA) a low‐head dam set above a ~200‐m bedrock cascade was removed in 2015. We used radio‐telemetry to assess landlocked Atlantic salmon passage at the remaining cascade (2020, 2022). Across years, 52% of males (13/25) attempted cascade passage whereas females made no discernable attempts (0/11). Attempt probability increased with stream discharge and decreased with fish size, though overall passage su...
A machine learning framework for California vineyard water status monitoring using sUAS Imagery and short-term meteorological dataNARA Subscribed
Efficient irrigation management is essential for sustainable crop production under increasing temperatures and tightening water supplies. In vineyards, water status significantly influences vine growth, yield, and fruit quality, and deficit irrigation is often used to impose controlled stress while avoiding damaging levels of water limitation. This creates a practical need for routine, field-scale monitoring of vine water stat...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Chagas disease remains a major public health challenge, and there is a need for new therapeutic agents. N-heterocyclic carbene (NHC) complexes, particularly those linked to silver or gold, have shown significant anticancer, antimicrobial, and antiparasitic activities. This study aimed to evaluate the efficacy of four NHC compounds (QMT3, QMT4, QMT7, and QMT8) against Trypanosoma cruzi , the causative agent of Chagas disease. I...
