Analysis Of Molecular Variation In The Federally Endangered Astragalus Jaegerianus (Fabaceae, Papilionoideae): A Species With A Restricted Geographic Range, George Floyd Walker Jan 2005

Analysis Of Molecular Variation In The Federally Endangered Astragalus Jaegerianus (Fabaceae, Papilionoideae): A Species With A Restricted Geographic Range, George Floyd Walker

Theses Digitization Project

The purpose of this study is to investigate the level and distribution of genetic variation in Astragalus jaegerianus by using molecular markers. The objectives of the study are: to estimate levels of genetic variation within and among populations of Astragalus jaegerianus; to test the hypothesis that levels and patterns of genetic variation in species of restricted ranges and few individuals is low and partitioned at the population level; and to discern whether, or how well, genetic partitioning of Lane Mountain milk vetch correlates with its geographic partitioning in the field.


Ecological Correlates Of Protein Polymorphisms In A Desert And Non-Desert Population Of Belonia Saturata (Odonata: Anisoptera), Melissa Jean Hamilton Jan 1996

Ecological Correlates Of Protein Polymorphisms In A Desert And Non-Desert Population Of Belonia Saturata (Odonata: Anisoptera), Melissa Jean Hamilton

Theses Digitization Project

Two populations of the Big Red Skimmer Dragonfly, Belonia saturata (Odonata: Amisoptera), were studied to determine the thoracic temperatures maintained during flight, the presence of polymorphic enzyme systems, and to determine the differences in activity of glycerol-3-phosphate dehydrogenase between a desert and non-desert population.
