A novel landscape ecology approach for determining microhabitat correlations and faunal patchiness in extreme environments:pilot study for the Southern East Pacific Rise at 17-18° S

Creator:: Wargo Rub, Michelle
Abstract:: Since their discovery in 1977, hydrothermal vent communities have offered scientists a unique glimpse into a world that is supported primarily by chemically derived energy rather than direct energy from the sun. Furthermore, studies of hydrothermal vent ecosystems have introduced scientists to amazing animals that have successfully adapted to living...

Meadow classification in the Willamette National Forest and conifer encroachment patterns in the Chucksney-Grasshopper meadow complex, Western Cascade Range, Oregon

Creator:: Dailey, Michele Meadows
Abstract:: This study delineates and characterizes the distribution of montane meadows in the Willamette National Forest, identifies encroachment patterns in relation to topographic features and proximity to trees in the Chucksney-Grasshopper meadow complex, and examines tree species and age distributions in relation to distance from forest edges or isolated tree clusters...

A geospatial data catalog and metadata management tools for the U.S. Environmental Protection Agency’s Western Ecology Division

Creator:: Bradford, David L.
Abstract:: The EPA’s Western Ecology Division (WED) had been accumulating geographic information system (GIS) data files for up to 20 years. There was no index or catalog for these files; locating data became more difficult over time. More that 4 Tb of data existed on numerous disk volumes in hundreds of...

Development of benthic habitat maps and GIS (Geographic Information System) modelling to support coastal zone management in Phu Quoc, Vietnam

Creator:: Nguyen, Vinh X.
Abstract:: Situated off the west coast of Vietnam in the Gulf of Thailand, Phu Quoc archipelago and its waters are well-known for their rich natural resources, especially the bounty of fishery resources. Under increasing pressure from the growing population, fishing, and tourism development, there is a strong need to formulate an...

Mapping vegetation using landsat TM and ETM+ in Eritrea

Creator:: Iyob, Biniam
Abstract:: The objective of this study was to examine vegetation and vegetation change in Eritrea over a period from the mid 1980s to 2002 using satellite remote sensing, and relate observed changes to the recent history of drought and war in the region. Specific objectives were (1) to examine vegetation change...

Development of predictive mapping techniques for soil survey and salinity mapping

Creator:: Elnaggar, Abdelhamid A.
Abstract:: Conventional soil maps represent a valuable source of information about soil characteristics, however they are subjective, very expensive, and time-consuming to prepare. Also, they do not include explicit information about the conceptual mental model used in developing them nor information about their accuracy, in addition to the error associated with...

Mapping vegetation density and water inundation in a recovering wetland : the Mesopotamian Marshlands

Creator:: Bosley, Jon Michael
Abstract:: Once considered the largest wetland in Central Asia, the Mesopotamian Marshlands of Southeastern Iraq have nearly disappeared. Various hydrological projects by the Iraqi government and dam construction in the region have nearly destroyed these once rich freshwater wetlands by over 90%. With the launching of Operation Iraqi Freedom recent attempts...

If you build it, will they come? Evolution towards the application of multi-dimensional GIS to fisheries-oceanography

Creator:: Vance, Tiffany C.
Abstract:: The development of new technologies in science is a balance between existence and use. There are three versions of this duality – something is built and users come, something is built and users don’t come, and, finally, potential users show up but the ballpark has not yet been built. In...

Regional-level coastal management in Mexico : A proposal for Quintana Roo

Creator:: Valdes, Carlos
Abstract:: The overall objective of this study is to propose a framework or model for comprehensive management model of coastal development in Quintana Roo (Quintana Roo's Coastal Management Program-QRCMP), using a regional approach.

Spatial interpolation in other dimensions

Creator:: Martin, Peter
Abstract:: The purpose of this work is to broaden the theoretical foundations of interpolation of spatial data, by showing how ideas and methods from information theory and signal processing are applicable to the the work of geographers. Attention is drawn to the distinction between what we study and how we represent...
