The Toxicology Investigators Consortium 2024 Annual ReportNARA Subscribed
Summary Ventilagineae (Rhamnaceae) is a tribe of palaeotropical climbing plants, comprising two genera: Smythea and Ventilago . Previous studies have established the monophyly of the tribe, but the relationships within it remain unclear. This research includes six species of Smythea and seven species of Ventilago in a molecular phylogeny using the Angiosperms353 probe set. The results show that Ventilago is paraphyletic, with...
Nutrient limitation of forest growth has been difficult to predict, and in temperate forests, long‐term tests of single‐nutrient versus multiple‐element limitation are few. Nutrient co‐limitation is the expected outcome of the ability of plants to adjust allocation to minimize limitation by any single resource. Nutrient limitation of productivity in northern hardwood forests was predicted by the Multiple Element Limitation (ME...
Pediatric Exposures Associated with Caffeine Energy Products Reported to United States Poison Centers, 2011–2023NARA Subscribed
Introduction This study investigated the characteristics and trends of pediatric exposures to caffeine energy products reported to US poison centers Methods National Poison Data System data for caffeine energy product single-substance exposures during 2011–2023 among individuals < 20 years old were analyzed. Results There were 32,482 caffeine energy product exposures reported to US poison centers with a 17.3% exposure rate inc...
The Australian lungfish, Neoceratodus forsteri, is one of the world’s oldest vertebrate lineages, with a slow life-history and threatened status, requiring immediate conservation efforts. The main threats to lungfish populations are degradation and availability of key macrophyte habitats, water regulation and flow modification. As this long-lived species (at least 77 years) has delayed maturity (mature at 10 years), field moni...

Dominance and rarity in tree communities across the globe: Patterns, predictors and threatsNARA Subscribed
Aim Ecological and anthropogenic factors shift the abundances of dominant and rare tree species within local forest communities, thus affecting species composition and ecosystem functioning. To inform forest and conservation management it is important to understand the drivers of dominance and rarity in local tree communities. We answer the following research questions: (1) What are the patterns of dominance and rarity in tree...
CamTrapAsia : A dataset of tropical forest vertebrate communities from 239 camera trapping studiesNARA Subscribed
Information on tropical Asian vertebrates has traditionally been sparse, particularly when it comes to cryptic species inhabiting the dense forests of the region. Vertebrate populations are declining globally due to land‐use change and hunting, the latter frequently referred as “defaunation.” This is especially true in tropical Asia where there is extensive land‐use change and high human densities. Robust monitoring requires t...

This study determines the threshold for the computational rate of actuator motor controllers for unmanned underwater vehicles necessary to accurately follow discontinuous square wave commands. Motors must track challenging square-wave inputs, and identification of key computational rates permit application of deterministic artificial intelligence (D.A.I.) to achieve tracking to a machine-precision degree of accuracy in direct...
Seventy five percent of the world's food crops benefit from insect pollination. Hence, there has been increased interest in how global change drivers impact this critical ecosystem service. Because standardized data on crop pollination are rarely available, we are limited in our capacity to understand the variation in pollination benefits to crop yield, as well as to anticipate changes in this service, develop predictions, and...
Phylogeography and post‐glacial dynamics in the clonal‐sexual orchid Cypripedium calceolus L.NARA Subscribed
Aim We investigated the phylogeographical history of a clonal‐sexual orchid, to test the hypothesis that current patterns of genetic diversity and differentiation retain the traces of climatic fluctuations and of the species reproductive system. Location Europe, Siberia and Russian Far East. Taxon Cypripedium calceolus L. (Orchidaceae). Methods Samples (>900, from 56 locations) were genotyped at 11 nuclear microsatellite loci...
Breast cancer metastasis through the lympho-vascular systemNARA Subscribed
Motivation The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community‐led open‐source database of biodiversity time series. Our goal is to accelerate and facilitate quantitative analysis of temporal...
