The Influence Of Northern Hemisphere Teleconnections On The Geography Of Pacific Tropical Cyclone Genesis, Nicholas Ray Adkins Jan 2018

The Influence Of Northern Hemisphere Teleconnections On The Geography Of Pacific Tropical Cyclone Genesis, Nicholas Ray Adkins

Theses, Dissertations and Capstones

The research in this thesis used statistical and spatial analysis methods to test the influence of six Northern Hemisphere teleconnection patterns on the latitude and longitude components of tropical cyclogenesis occurring in the eastern and western North Pacific Ocean basins for the period 1979-2016. The Pacific-North American (PNA), West Pacific (WP), El Niño Southern Oscillation (ENSO), Pacific Decadal Oscillation (PDO), Madden-Julian Oscillation (MJO), and Quasi-Biennial Oscillation (QBO) teleconnection patterns were examined independently and in combination for association with variations in cyclogenesis geography. Four of the six teleconnection patterns were found to exert an influence on cyclogenesis latitude and/or longitude in …


Spatial Modelling And Wildlife Health Surveillance: A Case Study Of White Nose Syndrome In Ontario, Lauren Yee Jan 2018

Spatial Modelling And Wildlife Health Surveillance: A Case Study Of White Nose Syndrome In Ontario, Lauren Yee

Theses and Dissertations (Comprehensive)

Wildlife data is often limited by survey effort, small sample sizes, and spatial biases associated with collection and missing data. These factors can create unique challenges from a surveillance perspective when trying to extract spatial patterns of habitat suitability and disease distributions for conservation and management purposes. This thesis examined data quality from a wildlife health database in the context of spatial analysis of wildlife disease. Spatial analysis of the data to predict habitat suitability of bats and white nose syndrome afflicted bats was examined by using the MaxEnt modelling method. Methods to reduce spatial bias were examined and specific …
