Priority effects of foliar fungal endophytes in leaf litter decomposition by Tawny Bolinas, 2023 Jim Jokerst Field Botany Grant Award Winner

Foliar endophytic fungi can defend against pathogens and help plants retain water in arid environments, but many of their ecological roles remain unclear. We hypothesized that certain endophytes persist in leaves as dormant commensals, becoming active upon senescence to initiate decomposition and influence subsequent fungal community assembly via priority effects.

Evolution of the Fire-Adapted California Flora by Jon E. Keeley, USGS Senior Research Scientist & UCLA Adjunct Professor

Understanding how fire has shaped plant adaptations requires recognition of the different fire regimes in a range of ecoregions in the state. In this presentation I will explore fire regimes in herbaceous, shrubland and forest types throughout the state and how different regimes have selected for different fire-adaptations.
