Effects Of Management And Population Size On Genetic Diversity Of Eggert's Sunflower (Helianthus Eggertii; Asteraceae), John Howard Starnes
Masters Theses & Specialist Projects
Helianthus eggertii (Asteraceae) is a federally threatened sunflower species that typically grows between open woods and barrens. This species has both sexual and asexual modes of reproduction, which can influence the amount of genetic diversity present within and among populations. Maintaining genetic diversity is one of the primary objectives in managing threatened species or populations. Fire and population size may influence genetic diversity. Two Inter-Simple Sequence Repeat Markers (873 and MAO) were used to characterize many important genetic parameters of 17 populations in 2003 and four populations in 2004. This information was used to assess the effectiveness of different conservation …
