Application Of The Genetic Algorithm To An Ecological Simulation, William J. Seufzer Jan 2001

Application Of The Genetic Algorithm To An Ecological Simulation, William J. Seufzer

Dissertations, Theses, and Masters Projects

A computational framework is built and demonstrated which is capable of testing plant growth strategies. The framework consists of Vgrass, a carbon based simulation model of a single Zostera marina plant, and the genetic algorithm (GA). Vgrass is based on published seagrass models, published photosynthetic data, and general plant physiology information. The model grows individual leaves whose initiation times are based on degree-day intervals. Leaf size is computed and combined with shoot density to compute population self shading. Leaf length is an emergent property since leaf growth is limited by light attenuation caused by self shading. The model is able …

A Systematic Treatment Of Acacia Coulteri (Fabaceae, Mimosoideae) And Similar Species In The New World, Jennifer T. Jawad, David S. Seigler, John E. Ebinger Jan 2000

A Systematic Treatment Of Acacia Coulteri (Fabaceae, Mimosoideae) And Similar Species In The New World, Jennifer T. Jawad, David S. Seigler, John E. Ebinger

VIMS Articles

Detailed descriptions, habitat preferences, geographic ranges, and representative specimens are given for the 13 taxa of the Acacia coulteri group from Mexico, Central America, and the southwestern United States. These species form a distinct group within Acacia series Vulgares, lacking prickles and usually having persistent stipules. A principal components analysis (PCA) of vegetative and floral features shows that the specimens examined form discrete units in plots of the first three principal components. The groups established by PCA mostly coincide with previously described species. The taxa within this group are phenetically similar, sharing many morphological features. These data also suggest …

Ecological Dispersal Mechanisms, Reproductive Ecology, And The Importance Of Scale In Zostera Marina In Chesapeake Bay, Matthew C. Harwell Jan 2000

Ecological Dispersal Mechanisms, Reproductive Ecology, And The Importance Of Scale In Zostera Marina In Chesapeake Bay, Matthew C. Harwell

Dissertations, Theses, and Masters Projects

Previous knowledge of the seed ecology of the clonal seagrass Zostera marina L. (eelgrass) suggests that sexual reproduction is not very important to the population dynamics of eelgrass; however, researchers have hypothesized long-distance dispersal for nearly a century. From a bay-wide sampling effort, viable eelgrass seeds in the seed bank were found throughout most of the lower and middle Chesapeake Bay, but abundance of seeds was highly variable. Lower seed-bank densities were found in middle Chesapeake Bay, the region with slow recovery of eelgrass populations. From natural and artificially created eelgrass populations, regional environmental conditions were found to have a …
