Life History and Case Building Behaviors of Phylloicus ornatus (Banks) (Trichoptera: Calamoceratidae) In Two Spring Fed Tributaries in the Central Edwards Plateau Bioregion of Texas
… first order streams in the Edwards Plateau Bioregion of Texas were studied from January 1998 to November 1999. Field larval, pupal and adult samples and laboratory rearings indicated a multivoltine cycle. First instars differ from late instars in number of labral setae and in having a unique …

Biogeography and potential factors regulating shallow subtidal reef communities in the western Indian Ocean
… area corresponding in location to the Delagoa Bioregion, one of three bioregions also revealed by post-hoc analyses. Significant differences in total average biomass and trophic structure were evident among bioregions, with a number of inter-bioregional trends in trophic groups being apparent. …

Land use change and bordering in the Greater Mapungubwe transfrontier conservation area
This study uses bioregionalism and bordering as a lens for understanding the construction of Mapungubwe as a transfrontier conservation area and the effects of that process on biodiversity, the local economy and local communities. The main assumption underlying the study is that transfrontier …

Sediment Management for Aquatic Life Protection Under the Clean Water Act
… the 5 combined ecoregions, 65% for the Mountain bioregion (comprised of Central Appalachian, Ridge and Valley, and Blue Ridge ecoregions), and 88% for the Piedmont bioregion (comprised of Northern Piedmont and Piedmont ecoregions). Thresholds for conductivity are 366 µS/cm for combined …

Oneota Cultural Interaction in the Prairie Peninsula: A Study of Ceramic Vessels and Faunal Exploitation in Northern Illinois
… Native societies of the Prairie Peninsula bioregion and its environs are shown to share power constrained by tradition and obtained through visions. Dreams provide inspiration to create imagery in artwork and ritual that reflects their cosmology and ideology. Native cosmology in the Prairie …

Bioregional planning in southeastern Tanzania : the Selous-Niassa corridor as a prism for transfrontier conservation areas
… a lens through which the process of constructing bioregions can be understood and the effects of that process on society properly evaluated. It specifically investigates the corridor as a cog in the creation of a bioregion in southeastern Tanzania, namely, the Selous-Niassa transfrontier …

Stream invertebrates and water temperature : evaluating thermal tolerances in the Cape floristic region (South Africa) - implications of climate change
… insect nymph species from the southwest fynbos bioregion and the south coast fynbos bioregion. The results from the experiments provided information on the relative thermal sensitivities of the species. Overall Aphanicerca capensis (form C and undescribed form), Notonemouridae ranked as the most …

Bioregions and future state visioning: a visually integrative approach to the presentation of information for environmental policy and management.
… explores the comparatively new philosophy of bioregionalism to see what it might have to offer the environmental management process. The foundations of bioregional philosophy stretch back into the early part of last century with roots in the thinking of the early 'anarchist geographers' such …

Ecological and physiological responses of hard corals to variations in seawater carbonate chemistry
… habitats. The thesis demonstrates that across bioregion sites non-reef habitats exist that have highly variable carbonate chemistry but still house corals. These non-reef habitats have very different carbonate chemistry, influencing both their own susceptibility to future OA and their potential …

Patterns of plant species richness and diversity across two habitat types in the Upper Karoo, South Africa
… shale gas exploration area in the Upper Karoo bioregion. Data were collected on species richness, relative cover, and growth form diversity of the observed vegetation. Soil samples were collected from each Whittaker plot, and climate data were obtained by point sampling from raster layers using …

Digital change detection and separation of anthropogenic and natural impacts on ecohydrological conditions in the Pilbara region, WA
… inflow dependent ecosystems maps for the Pilbara bioregion. The change detection method was also effective in detecting various spatial and temporal scales of changes and separating anthropogenic and natural impacts. It was further discovered that climate has had significant impacts on the assets …

Archipelago: a Literary Ecology of Heligoland and the Frisian Coast
… Heligoland and the surrounding coastal area as a bioregion, an area with a fluid, ambivalent identity, crossing national borders and looking outwards to the marine environment; an identity shaped by the slow changes of geology and the movement of the North Sea. Drawing on psychogeography, memoir …

Enclosed Edens, Contested Waters & Failed Utopias: An Ecocritical Reading of Epistemic Land Claims in Okanagan Literature
… primarily deploys an ecocritical and bioregional approach to literary analysis. This work also employs autotheory, a mode that seeks to lay bare some of the “entanglement of research and creation” and “reveals the tenuousness of maintaining illusory separations between art and life, …

Plant community restoration on mima mounds at Turnbull National Wildlife Refuge, WA
… Eastern Washington's Channeled Scablands bioregion has highly fragmented remnant patches of grassland underlain by glacial alluvium and basalt bedrock that are dotted with Mima mounds (naturally occurring aggregations of fine particle soil). The mounds provide valuable habitat for native …
