Intraspecific variation in stomatal architecture, gas exchange, and drought response of a dominant prairie grass sourced from broad climatic gradients

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Understanding how plant populations adapt to water limitation through stomatal traits is key to predicting drought responses. The dominant C4 grass Andropogon gerardi, distributed across sharp climate gradients in North America, offers an excellent focal species to study stomatal architecture (size and density).

Rangewide responses of Mimulus cardinalis to an extreme heat event

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Extreme events are an understudied aspect of ongoing anthropogenic climate change that could play a disproportionate role in the threat that rapid environmental shifts pose to natural populations. Methods We exposed plants originating from seeds that were harvested before (ancestors) and after (descendants) multiple extreme heat events

Wind‐driven seed dispersal differentially promotes seed trapping and retention across alpine plants

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Seed dispersal can mediate species interactions between plants across life stages. Plants can physically stop seed movement (seed trapping) and prevent further dispersal following entrapment (seed retention). We therefore hypothesized seed trapping and retention rates depend on the physical attributes of interacting seeds and plants ...

Structural problems without structural solutions? Youth leaders' perceptions of their community

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract As young people explore and reflect on the conditions of their neighborhoods and communities, they can forge a critical consciousness—merging their perspectives and analysis to direct both individual and collective actions. Photovoice is a methodological tool that allows participants to document their perspectives and analysis and discuss with
