Ecology

Plant ecology is a subdiscipline of ecology which studies the distribution and abundance of plants, the effects of environmental factors upon the abundance of plants, and the interactions among and between plants and other organisms.

Genomes only make sense in the light of evolution, so we use a combined evolutionary and bioinformatics approach to study the parts of genomes people know least about: centromeres, repetitive and other noncoding DNA. We are also interested in the invisible world of microbes. By studying the genomes of wine yeast we hope to answer fundamental…

My research focuses on the ecological and evolutionary questions concerning plant reproduction. My students and I study the processes that generate and maintain genetic variation in characters important for reproductive success of plants in natural populations. We combine observations from natural populations, manipulative experiments in the…

The Donovan lab investigates plant evolutionary ecophysiology, with an emphasis on resource use and stress tolerance traits as they relate to plant performance. We study adaptations to growth limiting factors such as drought, nutrient limitations, and salinity. Our current study system primarily consists of wild and cultivated sunflowers that …

My current research interests are in the broad areas of bioinformatics and plant evolutionary/ecological genetics. We are studying the genetics, evolution, and ecology, of the insect-eating pitcher plants (Sarracenia species). Most of my bioinformatics work is in collaboration with Liming Cai of the Computer Science Department to develop…

My research interests encompasses several areas related to wind damage to trees and forests: 1) patterns of tree and forest damage, at single-tree, stand, and landscape scales; 2) the patterns of regeneration after wind disturbance; 3) the impact of salvage logging after wind disturbance; 4) individual tree wind firmness; and 5) using tree and…

The unifying theme of my research is investigation of the evolutionary factors that shape patterns of genetic variation in natural plant populations and the manner in which species-wide diversity is partitioned and maintained at various spatial and temporal scales. More specifically, my lab studies: i) contemporary gene flow using direct…

I conduct floristic surveys in Georgia and neighboring states. These are field-based studies comprising a plant survey of a natural area, resulting in a complete inventory supported by voucher specimens deposited in a recognized herbarium.  Floristic inventories are an important function of the GA Herbarium.

The herbarium staff and I are…
