Abstract:: Astragalus oniciformis Barneby is a xerophyte of the sagebrush deserts of central Idaho. It is a narrow endemic of the upper Snake River Plains where it inhabits stabilized, aeolian sand deposits over Quaternary basalt flows. The objective of this study was to determine the levels and distribution of genetic differentiation...

Abstract:: Pollination ecology may play an important role in the maintenance of selfing in populations of self-compatible hermaphroditic plants where both selfing and outcrossing occur (mixed mating). Behavior and abundance of pollinators can influence the two major modes of selfing; autogamy (selfing within a flower) and geitonogamy (selfing between flowers on...

Creator:: Messinger, Wes
Abstract:: Infrageneric classification in Ribes has previously relied on a few, often conflicting, morphological markers, such as spines, glands, and inflorescence morphology. Suggestions that hybridization drives the evolution of the genus have not been tested using phylogenetic methods. To assess the validity of infrageneric classifications and the importance of hybridization to...

Abstract:: Plantago ovata Forssk. (Plantaginaceae) is a winter annual species which, in North America, inhabits desert and Mediterranean habitats of the southwest United States, northwest Mexico and the Channel Islands of California and Mexico. In the eastern hemisphere P. ovata inhabits desert regions ranging from the Canary Islands, across northern Africa...

Abstract:: Plastid DNA restriction site and rearrangement mutations were used to study phylogenetic relationships among hard pines (subgenus Pinus). Total genomic DNA was cut with 19 restriction enzymes, blotted, and then probed mostly with 80% of the Douglas-Fir (Pseudotsuga menziesii) chioroplast genome (cpDNA) {initial study, using only 6bp recognition enzymes}; or,...
