Population genetic structure of Jeffrey pine

Creator:: Furnier, Glenn Richard
Abstract:: Jeffrey pine occurs in the mountains of California and adjacent states. In the Klamath Mountains, the northern margin of the range, it is restricted to infertile ultramafic soils, forming very open stands of low density. It occurs predominantly on more fertile soils in the Sierra Nevada and southern portions of...

Population and conservation genetic structure of the Cascades frog, Rana cascadae throughout the species' range

Creator:: Monsen, Kirsten J.
Abstract:: A major goal of conservation biology is to elucidate the population genetic structure in threatened species and assess the relative importance of the evolutionary forces that shape that population genetic structure. I conducted three studies in the declining amphibian Rana cascadae to assess levels of population genetic differentiation and the...

Quantitative genetic structure of Douglas-fir populations from southwest Oregon

Creator:: Hamlin, James
Abstract:: The major objectives of this study were: (1) to determine the extent to which southwest Oregon populations of Douglas-fir [Pseudotsuga menziesii var menziesii (Mirb.) Franco) differ in quantitative genetic structure (QGS); (2) to determine whether differences in QGS are associated with the environments from which populations originate; and (3) to...

Isozymic and cytological studies on populations of the introduced bee species, Megachile (Eutricharaea) rotundata and M. (Eutricharaea) apicalis

Creator:: Chen, Xiaoshe
Abstract:: Thirteen New World populations of Megachile rotundata and M. apicalis and two Old World populations of M. rotundata were analyzed at 23 enzyme loci using cellulose acetate electrophoresis. Conventional and G- or C-banded karyotypes were also examined in these populations. The principal findings are (1) No differences were found in...

Spatial and temporal scales of genetic change in two overfished rockfishes

Creator:: Gomez-Uchida, Daniel
Abstract:: Pacific rockfishes (genus Sebastes) have attracted wide scientific and public interest from an evolutionary, fishery and conservation standpoints. This dissertation addresses several hypotheses involving spatial and temporal scales of genetic change in two overfished rockfishes, darkblotched (S. crameri) and canary rockfish (S. pinniger), using statistical analyses of genetic variation within...

Genetics of sexuality and population genetics of Phellinus weirii

Creator:: Angwin, Peter A.
Abstract:: Phellinus weirii (Murr.) Gilbertson, cause of laminated root and butt rot, is a heterothallic basidiomycete lacking clamp connections. Two biological species groups of the fungus have been hypothesized, the Douglas-fir and cedar-types, on the basis of physiological, morphological and epidemiological differences. Single-spore and vegetative isolates differ in cultural morphology, nuclear...

Selection for hybrid female reproductive performance in the mouse

Creator:: Chapman, Verne Merrill
Abstract:: The design of this study was suggested by the following observations: (1) the successful application of recurrent selection techniques in obtaining improvement of hybrid performance in corn and Drosophila, (2) the increased production realized by rotational crossbreeding, and (3) the expression of a relatively large degree of hybrid vigor in...
