Does the abiotic environment influence the distribution of flower and fruit colors?

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...

Osmoxylon‐like fossils from early Eocene South America: West Gondwana–Malesia connections in Araliaceae

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Araliaceae comprise a moderately diverse, predominantly tropical angiosperm family with a limited fossil record. Gondwanan history of Araliaceae is hypothesized in the literature, but no fossils have previously been reported from the former supercontinent.

Mast years increase wind pollination and reduce seed predation in sugar maple (Acer saccharum)

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise In general, mast seeding (intermittent and synchronous seed production) increases plant fitness through economies of scale in which reproduction is more successful in high‐seed years. These benefits have been most studied in wind‐pollinated trees.
