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...

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...
