SUGGESTIVE PLACEMENT OF Quassia borneensis Noot. (Simaroubaceae) AS INDICATED BY ISOLATION OF ITS QUASSINOIDS

open access: yes, 2015
Quassinoids have been reported to possess numerous biological activities such as anticancer, antimalarial and phytotoxicity. They are degraded triterpenoids which give bitterness characteristic of Simaroubaceae and classified according to their basic ...

Dispersal and delimitation: Phylogenomics of Connaraceae prompts revised generic delimitation in Cnestideae and reveals global biogeographic patterns

open access: yesTAXON, Volume 75, Issue 2, April 2026.
Abstract The tempo and mode of assembly of the world's most diverse, tropical floras remain poorly known. Evolutionary relationships within pantropical plant clades such as Connaraceae (Oxalidales, ca. 220 species) offer an opportunity to address this issue.

Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

open access: yesApplications in Plant Sciences, Volume 14, Issue 2, March-April 2026.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Wing and Pappus Appendages Decrease Seed Terminal Velocity: A Meta‐Analysis

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This meta‐analysis integrated terminal velocity records for 1479 species from various sources and explored descriptive patterns by taxonomic group, seed dispersal vector, and seed appendage type. This study revealed that wing and pappus appendage decrease seed terminal velocity with a robust analysis using regression models to predict terminal velocity.

Harnessing community science and open research‐based data to track distributions of invasive species in Japan

open access: yesConservation Science and Practice, Volume 8, Issue 2, February 2026.
Information gaps about invasive alien species (IAS) distributions hinder local governments in Japan, where many prefectures still lack official lists. This study shows that open research‐based data (ORD, GBIF.org) from museums and herbaria and community science data (CSD, Biome and iNaturalist) from volunteers can substantially reduce these gaps.
