Competition under Drought

IMG_7478

Drought does not operate independent of other variables and in order for us to begin to understand the impacts altered climates will have on tree, we need to begin assessing the role of climate in conjunction with plant-plant interactions, plant-soil interactions and plant-herbivore interactions. I have 20 permanent plots throughout the Malua forest that have seedlings growing within three different neighborhood communities: 1) all seedlings are from the same seed family, 2) all seedlings are from the same species but different seed families and 3) all seedlings are from different species. We apply drought to these communities every year using rain exclusion shelters in order to test the relative importance increasing diversity has on buffering the effects of drought.
