Creator:: Farrell, Kelly Anne
Abstract:: Humans are increasing the scale and frequency of many natural disturbances, as well as adding novel disturbances to ecosystems. This thesis uses the arthropod community as a metric to examine the multi-trophic responses to disturbances in California grasslands. Chapter 2 explores how the long-term exclusion of native vertebrate herbivores has...
Resource Type:: Masters Thesis

Creator:: Moore, Sean M.
Abstract:: Like other species interactions in ecological systems, host-pathogen interactions are influenced by environmental factors, landscape characteristics and the broader community context. My thesis explores the potential influences of food-web interactions (Chapter 2), climate change (Chapter 3), landscape structure and host movement patterns (Chapter 4), and the combined influences of local...

Creator:: Benfield, Cara D.
Abstract:: Successful conservation management requires an understanding of how species respond to intervention. Native and exotic species may respond differently to management interventions due to differences arising directly from their native or exotic origin (i.e., provenance) or from differences in life-history or phylogenetic lineage that are associated with provenance. Thus, selection...

Creator:: Schumann, Canan B.
Abstract:: Maintenance of optimal nutrient supplies is fundamental to the functioning of vertebrate, invertebrate, bacterial and plant physiology. Organisms on this planet compete with each other primarily to fulfill nutritional needs in order to maximize their health, wellbeing, and reproductive success. Here we examine nutrient concentrations in several different grass species...

Creator:: Adams, Vincent T.
Abstract:: Barley yellow dwarf virus (BYDV) is a globally distributed pathogen of grasses that is transmitted by aphids. Little research has been done examining the response of aphids to different host grasses in naturally mixed communities. We measured the short-term fecundity of the aphid Rhopalosiphum padi, a widely distributed vector of...
