American Journal of Botany, EarlyView.Abstract Premise Climate change is altering the timing of many plant phenological events, yet most studies focus on flowering, with less attention given to later reproductive stages such as fruit development and ripening. Vaccinium angustifolium (lowbush blueberry) is an important perennial berry species that may be sensitive to these changes.

American Journal of Botany, EarlyView.Abstract Premise The inclusion of heterotrophic plants in broader systematic studies is challenging due to substantial morphological modification, gene loss, and accelerated substitution rates following photosynthesis loss. In particular, inclusion of very long branch (VLB) taxa with highly elevated rates may lead to phylogenomic misinference.

Applications in Plant SciencesPremise Astragalus (Fabaceae) is the largest genus of flowering plants, with about 3100 species. Most phylogenies of the genus are based on a few nuclear or plastid loci (with one exception that uses ~100 loci) and usually provide poorly resolved trees ...

Turning a new leaf: PhenoVision provides leaf phenology data at the global scale
Applications in Plant Sciences, EarlyView.Abstract Premise Plant phenology dictates many aspects of community function and ecosystem dynamics. Yet, global phenology data are still limited, especially in areas lacking monitoring programs. Here we present a new data resource, PhenoVision–Leaf, which extends a computer vision pipeline utilizing iNaturalist digital image vouchers to produce global‐
