1	Easily Overlooked: Modelling coastal dune habitat occupancy of threatened and endangered beach mice (Peromyscus polionotus spp.) using high-resolution aerial imagery and elevation models of the Northern Gulf of Mexico Burger, Wesley 07 August 2020 (has links) The Gulf of Mexico dune system is a broad and dynamic environment that varies greatly in geomorphology and vegetative composition across the Gulf coastline. Beach mice (Peromyscus polionotus spp.) are an endangered species that rely on coastal habitat structure. I hypothesized that beach mouse occupancy would be dependent upon coastal dune land cover and landform features. I identified coastal landforms using high-resolution elevation data and landform models in GRASS GIS and identified coastal dune vegetation classes using high-resolution aerial imagery and object oriented vegetation classification. These features were used to create a dynamic occupancy model to determine occupancy patterns in three subspecies of beach mice over multiple years of sampling. Beach mice demonstrated no distinct pattern in habitat occupancy over the study period. However, dynamic occupancy models demonstrated that habitat occupancy varied between individual sites, indicating that habitat selection may be population specific.

2	Using Digital Mapping Techniques to Rapidly Document Vulnerable Historical Landscapes in Coastal Louisiana: Holt Cemetery Case Study Moore, Alahna 18 May 2018 (has links) This thesis outlines a technique for rapid documentation of historic sites in volatile cultural landscapes. Using Holt Cemetery as an exemplary case study, a workflow was developed incorporating RTK terrain survey, UAS aerial imagery, photogrammetry, GIS, and smartphone data collection in order to create a multifaceted database of the material and spatial conditions, as well as the patterns of use, that exist at the cemetery. The purpose of this research is to create a framework for improving the speed of data creation and increasing the accessibility of information regarding threatened cultural resources. It is intended that these processes can be scaled and adapted for use at any site, and that the products generated can be utilized by researchers, resource management professionals, and preservationists. In utilizing expedited methods, this thesis specifically advocates for documentation of sites that exist in coastal environments and are facing imminent destruction due to environmental degradation. archaeology cemetery survey climate change coastal studies spatial database digital history documentation, GIS Holt Cemetery landscape studies Louisiana material culture New Orleans photogrammetry remote sensing spatial studies UAS survey American Material Culture Archaeological Anthropology Cultural History Digital Humanities Environmental Studies Genealogy Geographic Information Sciences Museum Studies Remote Sensing Spatial Science Urban Studies and Planning
