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

American 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.

A graviton propagator for inflation [PDF]

Class.Quant.Grav.25:055007,2008, 2007
We construct the scalar and graviton propagator in quasi de Sitter space up to first order in the slow roll parameter $\epsilon\equiv -\dot{H}/H^2$. After a rescaling, the propagators are similar to those in de Sitter space with an $\epsilon$ correction to the effective mass.

Moving towards better risk assessment for invertebrate conservation

Ecography, EarlyView.
Global change threatens a vast number of species with severe population declines or even extinction. The threat status of an organism is often designated based on geographic range, population size, or declines in either. However, invertebrates, which comprise the bulk of animal diversity, are conspicuously absent from global frameworks that assess ...
