The influence of linear landscape features on pollinator behaviour
Linear landscape features such as hedgerows are important wildlife habitats but their functional role in improving connectivity in fragmented habitats remains uncertain. This thesis studied the influence of both natural and artificial linear features on pollinator behaviour at medium and landscape …

Spatial and Temporal Activity of Migratory Bats at Landscape Features
Geographical landmarks may be important features for navigation of migrating bats although spatial and temporal activity may depend on species-specific migration strategies. I predicted that latitudinal migrating bats would have higher activity along north-south oriented linear landscape features, …

Soil Stable Carbon Isoptope Analysis of Landscape Features at Aguateca, Guatemala
… Soil profiles were collected from various landscape features around the Classic Maya site of Aguateca: bajos (or wetlands), control locations (areas not conducive to agriculture), defensible locations (areas within or near defensive walls), rehoyadas (natural karst depressions), and upland …

Climate change mitigation and adaptation through suburban sustainable landscape : a case study of the city of Colwood
This case study explores sustainable landscape features and solutions to the impacts of climate change in the City of Colwood, a suburban area on Vancouver Island in Canada. It does so by addressing this research question: What landscape features could be incorporated into a suburban landscape to …

An investigation into the effects of complex topography on particle dry deposition
… following a nuclear accident. The interaction of landscape features, atmospheric flow and particle dry deposition has been investigated with this in mind. Wind tunnel studies have been used with computational fluid dynamics to predict the deposition rate relative to a flat landscape. Good …

Residents' perceptions of agroforestry landscape: implications for agritourism
… perceptions of the visual appeal of agroforestry landscapes for recreational purposes in Missouri, Pennsylvania and Texas. Specific objectives of this study were: (1) to identify the features of agroforestry landscapes that are more visually appealing to visit a farm for recreation; (2) to assess …

The Huacas of Machu Picchu: Inca Stations for The Communion Between Humanity and Nature
… integrated human ritual with the surrounding landscape. I argue that huacas defined the relationship between nature and ritual practice by forcing an esoteric choreography which involved specific postures of the participant in order to visually orient humans to significant natural features of …

Assessing changes in connectivity and abundance through time for fisher in the southern Sierra Nevada
… genetic subdivision within the population, the landscape features shaping gene flow, and the detection of population declines. I detected a 90% decline in effective population size and dated the time of decline to over a thousand years ago. Analyzing historical and contemporary genetic samples, …

Effects of black flies on wild turkey reproductive success
… weather (e.g., precipitation and temperature), landscape composition (e.g., forest cover, streams, edge habitat, roads), and nest-site vegetation structure can influence nest success. Biting insects such as black flies (Diptera: Simuliidae) are a common nuisance often present during the …

Ground-Dwelling Arthropod Community Structure of Saskatchewan's Agroecosystems and Seeded Grasslands
… of agroecosystems in the Canadian prairie landscape. However, the distribution of many groups is often limited to non-crop habitats, such as roadside ditches or distantly spaced grassland refuges. The high prevalence of prairie pothole wetlands in this region may be working to mitigate this …

Landscape heterogeneity at multiple scales: effects on movement patterns and habitat selection of eleodid beetles
… with field experiments to investigate how landscape heterogeneity influences habitat selection in eleodid beetles of the shortgrass prairie of Colorado. I examined correlations in spatio-temporal patterns of habitat occupancy, population density, and community structure in eleodids with …

Multifunctional perennial landscape: small farm design in the Upper Sangamon River Watershed
… Findings will be used to support educational landscape-based design research and to develop decision-support tools for land owners who want to integrate MPCS on marginal farmland. This thesis explores using MPCS in the projective design of marginal areas of an actual 171 acre ranch north of …
