Factors Contributing To The Conservation Of Phacelia Submutica (Boraginaceae), A Threatened Species In Western Colorado: Reproductive Biology And Seed Ecology, Alicia M. Langton May 2015

Factors Contributing To The Conservation Of Phacelia Submutica (Boraginaceae), A Threatened Species In Western Colorado: Reproductive Biology And Seed Ecology, Alicia M. Langton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Conservation and recovery plans for rare species require biological and ecological information to discern how they may be susceptible to human disturbances. Phacelia submutica is a threatened annual species in western Colorado. Human activities including energy development, recreation, and livestock grazing are occurring within the species’ range. To provide conservation practitioners with a scientific basis for management, this research aimed to elucidate elements of the species’ ecology. Chapter 2 describes the reproductive biology of P. submutica. Potential insect pollinators were not observed during two years of observations. Floral traits and development ensure self-pollination and reduce the likelihood that insects …

Generally, statistics are based off the assumption that observations are independent from each other in space. In larger ecological systems however, there can be spatial autocorrelation whereby data collected in nearby areas are not independent of one another which violates the assumption of most statistical tests. It is therefore becoming commonplace for ecological studies to study spatial autocorrelation to both eliminate error (accounting for a nuisance variable that could give false positives) and to better understand the spatial structure of their system of interest. Indeed, the mechanisms that lead to spatial autocorrelation are often associated with behaviors and/or intrinsic characteristics …
