Movements And Conservation Of The Migratory White-Eared Kob (Kobus Kob Leucotis) In South Sudan, Malik D. Marjan Nov 2014

Movements And Conservation Of The Migratory White-Eared Kob (Kobus Kob Leucotis) In South Sudan, Malik D. Marjan

Doctoral Dissertations

The annual movements of white-eared kob (Kobus kob leucotis), tiang (Damaliscus korrigum tiang), in eastern South Sudan was investigated to provided appropriate information for developing effective conservation actions for the migratory kob. Although kob is the focus of the study tiang has been included as the two migrations are ecologically linked and overlap at least in the wet season. During the 20 years of the civil war which ravaged South Sudan, the kob and tiang populations were thought to be severely hunted for food by both the combatants and local people to the extent that their …


Integrated Modeling Of Land Use And Climate Change Impacts On Multiscale Ecosystems Of Central African Watersheds, Simon Nampindo Nov 2014

Integrated Modeling Of Land Use And Climate Change Impacts On Multiscale Ecosystems Of Central African Watersheds, Simon Nampindo

Doctoral Dissertations

Assessment and management of ecosystem services demands diverse knowledge of the system components. Land use change occurring mainly through deforestation, expansion of agriculture and unregulated extraction of natural resources are the greatest challenges of the Congo basin and yet is central to supporting over 100 million people. This study undertook to implement an integrated modeling of multiscale ecosystems of central African watersheds and model the impact of anthropogenic factors on elephant population in Greater Virunga landscape. The study was conducted at varied scales, regional, landscape, and community. Regional study included watershed analysis and hydrological assessment using remotely sensed data implemented …


Adaptive Radiation Along A Benthic/Pelagic Ecological Axis In North America’S Most Diverse, Endemic Clade Of Freshwater Fishes, Phillip Ray Hollingsworth Jr. May 2014

Adaptive Radiation Along A Benthic/Pelagic Ecological Axis In North America’S Most Diverse, Endemic Clade Of Freshwater Fishes, Phillip Ray Hollingsworth Jr.

Doctoral Dissertations

Eastern North America is unparalleled throughout the temperate world in terms of freshwater fish biodiversity. A monophyletic group of approximately 250 cyprinid fishes, known as the open posterior myodome (OPM) clade, dominates the fish species richness in the freshwater ecosystems of this region. In this dissertation, I explore the influence of eco-evolutionary divergence along a benthic/pelagic habitat axis on the generation of this hyper-diverse group of fishes. My three chapters work synergistically to address the question: Did a historical shift from benthic to pelagic habitats by OPM cyprinids represent the invasion of an open adaptive zone and result in the …
