Exclusion, Amelioration, Tolerance: An investigation of the physiological basis for tolerance in serpentine Mimulus guttatus
As sessile organisms, plants must cope with a variety of abiotic stress factors, including the mineral composition of soil. In serpentine soils, the low calcium-to-magnesium ratio has been shown to limit the growth and survival of many plant species. Some species are adapted to serpentine, employing a variety of physiological ...
From Cells to Canopies: Reconstructing Vegetation Structure and its Response to Climate Change in the Middle Cenozoic of Patagonia Using Phytolith Morphology
Reconstructing ancient ecosystems to answer outstanding questions in paleoecology requires a multidisciplinary approach. This dissertation research integrates geochronology and conventional phytolith analysis, with a new method for reconstructing vegetation structure (Leaf Area Index) based on the response of epidermal cell ...
