Seasonal and Simultaneous Cleistogamy in Rostrate Violets (Viola, subsect. Rostratae, Violaceae)
Plants, 2021 The special mixed reproductive system, i.e., the ability of an individual plant to develop both open, chasmogamous (CH) flowers adapted to cross-pollination and closed, cleistogamous (CL) flowers with obligate self-pollinating, is a common phenomenon in ...

Origin of subgenomes in the circumboreal, allopolyploid, carnivorous plant Drosera anglica
American Journal of Botany, Volume 113, Issue 3, March 2026.Abstract Premise The parentage of the widespread allopolyploid Drosera anglica, a member of the carnivorous sundew genus, remains uncertain despite over 100 years of morphological, cytological, and, more recently, molecular study. Methods Using transcriptomic and genomic data from 12 species of Drosera sect. Drosera, including four D.

Seasonal variation in wild pig (Sus scrofa) diet revealed by DNA metabarcoding
Wildlife Society Bulletin, Volume 50, Issue 1, March 2026.Using DNA metabarcoding of fecal samples, we investigated the diet of wild pigs at an extensive bottomland hardwood forest ecosystem within Felsenthal National Wildlife Refuge in Southern Arkansas. We found that wild pig diet was highly diverse and included at least 74 plant families and 106 genera and 23 species of vertebrates.

Adaptive Significance of Nickel Hyperaccumulation by Plants
Ecological Research, Volume 41, Issue 2, March 2026.Metal hyperaccumulation may enhance plant fitness through multiple, non‐exclusive mechanisms, including elemental defense against herbivores and pathogens, altered pollinator interactions, and increased reproductive performance in metal‐rich soils. Metals may also affect plant–plant interactions via elemental allelopathy and improve stress tolerance ...
