Transgenerational plasticity in the annual plant Polygonum persicaria: effects of the grandparent environment on plant development

by

Abstract: The Sultan lab studies phenotypic plasticity and its transgenerational effects in the generalist, annual plant Polygonum persicaria. Phenotypic plasticity describes the ability of a single genotype to produce multiple phenotypes (physical traits) in different environments. The plasticity we study allows plants to integrate information from their current and previous (parental and grandparental) environments in … Read more

Vegetation recovery, plant hydrology, and functional differences post-fire evapotranspiration in a southwestern pine-oak forest, Arizona, USA

by

Abstract: Post-fire stand, water balance, and hydrology are critical factors influencing vegetation recovery after a wildfire. Fire severity, and the amount of fire-induced tree mortality influence post-fire vegetation water cycling, as the rate of water movement from the soil to the atmosphere, depends upon the amount of live vegetation cover in the wake of wildfire. … Read more
