Lidar Remote Sensing Of Forest Canopy Structure: An Assessment Of The Accuracy Of Lidar And Its Relationship To Higher Trophic Levels, Christopher Felix Hansen Jan 2015

Lidar Remote Sensing Of Forest Canopy Structure: An Assessment Of The Accuracy Of Lidar And Its Relationship To Higher Trophic Levels, Christopher Felix Hansen

Graduate College Dissertations and Theses

Light detection and ranging (LiDAR) data can provide detailed information about three-dimensional forest horizontal and vertical structure that is important to forest productivity and wildlife habitat. Indeed, LiDAR data have been shown to provide accurate estimates to forest structural parameters and measures of higher trophic levels (e.g., avian abundance and diversity). However, links between forest structure and tree function have not been evaluated using LiDAR. This study was designed and scaled to assess the relationship of LiDAR to multiple aspects of forest structure and higher trophic levels (arthropod and bird populations), which included the ground-based collection of percent crown and …


Fixed Versus Plastic Partial Migration Of The Aquatic Macroinvertebrate, Mysis Diluviana, In Lake Champlain, Peter Thomas Euclide Jan 2015

Fixed Versus Plastic Partial Migration Of The Aquatic Macroinvertebrate, Mysis Diluviana, In Lake Champlain, Peter Thomas Euclide

Graduate College Dissertations and Theses

Partial migration, whereby populations consist of residents and migrants, is common among migrating organisms. Partial migration of aquatic organisms, however, remains largely under-studied even though many aquatic animals exhibit horizontal and vertical migrations during their lifetime. Macroinvertebrates of the genus Mysis exhibit diel vertical migrations (DVM). Some species have recently been observed to exhibit partial diel migrations where some individuals reside on the bottom throughout the night while others migrate into the water column. To test the hypothesis that individuals are fixed as residents or migrants, we compared demographic information and C and N isotope compositions of M. diluviana caught …


Modifiable Risk Factors For Cardiovascular Disease As Perceived By Women In Kenya, Catherine Wanjiru Lawrence Jan 2015

Modifiable Risk Factors For Cardiovascular Disease As Perceived By Women In Kenya, Catherine Wanjiru Lawrence

Graduate College Dissertations and Theses

Cardiovascular disease (CVD) worldwide has grown exponentially in the last two decades and while sub-Saharan Africa (SSA) has been grappling with the crippling effects of epidemic infectious diseases such as HIV/AIDS and malaria, cardiovascular disease is now emerging as a grievous concern. Research and resources have largely been directed toward understanding and curtailing infectious diseases in the African continent. But as the risk of cardiovascular disease reaching endemic proportions in sub-Saharan Africa becomes more evident, research is critically needed in order to understand how to manage it and more importantly to direct the development and implementations of culturally relevant prevention …
