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 ...

The interplay among space, environment, and gene flow drives genetic differentiation in endemic Baja California Agave sobria subspecies

open access: yesAmerican Journal of Botany, Volume 112, Issue 7, July 2025.
Abstract Premise Research on neutral and adaptive processes that lead to the divergence of species and populations is a crucial component in evolutionary and conservation genetics. Agave sobria is an endemic group of subspecies scattered on canyons along a latitudinal gradient and distinct environments of the Baja California Peninsula, Mexico.

Floral scent of artificial hybrids between two Schiedea species that share a moth pollinator

open access: yesAmerican Journal of Botany, Volume 112, Issue 7, July 2025.
Abstract Premise In flowering plants, pollinators' ability to recognize chemical displays of hybrids may erode reproductive barriers. Hybrids may produce novel or altered floral scent blends that are unattractive, or scents similar to either parent that remain attractive and promote backcrossing.
