Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

American Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Linking community structure and climate vulnerability in desert plant assemblages of southern California

American Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

Taxonomic reassessment of fossil Sequoia and Protosequoia from the Upper Miocene of Central Honshu, Japan, with implications for leaf morphological variation in extant S. sempervirens

American Journal of Botany, EarlyView.
Abstract Premise Since its emergence in the Mesozoic, Sequoia (Cupressaceae) has been considered to possess conserved leaf morphology. However, recent studies have shown that the leaves of extant S. sempervirens become smaller, with a scale form, with increasing tree height.

NO NĀ PUA: Exploring the feasibility of culture‐based social prescribing on firefighters' wellbeing in Hawaiʻi

American Journal of Community Psychology, EarlyView.
Abstract Firefighters face an array of stressors due to the demands of their occupation, leading to a high prevalence of mental health challenges. Social prescribing represents a novel approach to healthcare that emphasizes a holistic view of health and wellbeing.
