Stomatal distribution and post‐fire recovery: Intra‐ and interspecific variation in plants of the pyrogenic Florida scrub

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Amphistomy, the presence of stomata on both leaf surfaces, can increase photosynthesis yet is uncommon across vascular plants. The relative infrequency of amphistomy is often attributed to high costs, such as transpirational water loss.

Floral shape and color impact heat accumulation and thermal stability of the floral microenvironment in a subalpine meadow

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The floral thermal microenvironment impacts plant reproduction through its effects on gametophyte performance and plant–pollinator interactions. Color and shape are axes of floral variation that may mediate floral temperature because they affect the absorption and reflection of solar radiation, but their interactive effects are unclear.

Toward a macroevolutionary understanding of live‐leaf flammability in plant species of fire‐prone forests

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The flammability of live leaves in canopies varies considerably among plant species. Identifying macroevolutionary processes that shape variation in leaf flammability contributes to an understanding of the phylogenetic underpinnings of wildfire dynamics.

Phytochemical Investigation and Biological Evaluation of Disynaphia filifolia: A Novel Source of Tremetone in Asteraceae

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Chemical investigation of Disynaphia filifolia (Hassl.) R.M. King & H. Rob. (Asteraceae) led to the isolation of eight compounds, with tremetone being the major metabolite recovered. Tremetone has been suggested as the toxic compound in Ageratina altissima and Isocoma pluriflora, two species of the Asteraceae family. Although D.
