Phenotypic And Genetic Characterization Of Wildland Collections Of Western And Searls Prairie Clovers For Rangeland Revegetation In The Western Usa, Kishor Bhattarai
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Western prairie clover [Dalea ornata (Douglas ex Hook.) Eaton & J. Wright] is a perennial legume that occurs in the northern Great Basin, Snake River Basin, and southern Columbia Plateau, whereas Searls prairie clover [Dalea searlsiae (A. Gray) Barneby], also a perennial legume, occurs in the southern Great Basin and surrounding areas. Understanding the genetic and ecotypic variation of these prairie clovers is a prerequisite for developing populations suitable for rangeland revegetation in the western USA. DNA sequences of internal transcribed spacer (ITS/5.8S) and trnK/matK were used to study the phylogeny of these species. The species were distinguished …
Distribution And Genetic Structure Of Pocket Gophers (Genus Geomys) In Kansas, Zachary J. Schwenke
Distribution And Genetic Structure Of Pocket Gophers (Genus Geomys) In Kansas, Zachary J. Schwenke
Master's Theses
The development of informed management practices and insightful research depends not only on an understanding of species natural history and ecology, but information regarding the distributions of these species and how they interact with adjacent taxa. The study of a species distribution can become complicated if the geographic variation within the species is not understood. Pocket gophers, including those in the genus Geomys, display morphological and chromosomal variation across their range, even within the same species. Genetic techniques, including Amplified Fragment Length Polymorphism (AFLP), have clarified population relationships and characterized zones of contact. Previous studies have suggested 2 species and …
