Summer 2022 - UC Nature

Poison oak is known for both causing painful skin rashes and growing in a wide variety of forms. This phenotypic plasticity allows poison oak to flourish under the varied environmental conditions found across its range. Some plant species increase the density and reduce the size of their stomata, or leaf pores, in response to water stress. Research studying these characteristics in poison oak was done at Landels-Hill Big Creek Reserve by students of the Summer 2022 California Ecology and Conservation program. The image shows a stomatal peel, an imprint of the microscopic topography of a poison oak leaf surface. Image credit: Sabina Javier.
