The Physiography of Canada
<p>The physiographic features of Canada have a complex history which involve a Precambrian peneplain, followed by a long period of sedimentation interrupted in places by diastrophic events, and finally extensive glaciation. Since the turn of the nineteenth century several men have proposed …

The Role of Physiography in the Relationships Between Land Cover and Stream Fish Assemblages
… accounts for the causal relationship between physiography and land cover. Therefore, I recommend the use of LDPRs as a tool for stratifying watersheds based on physiography in future investigations so that the processes by which human land use results in stream degradation can be understood.

Stratigraphic evolution of Las Vegas Bay, Lake Mead, Nevada: 1935--2002
… sediment supply, fluvial discharge and basin physiography have had on stratigraphy of the basin. Mapping, seismic, sidescan sonar and bathymetry surveys, in conjunction with sediment cores, LPSA and 137Cs analyses were integrated to develop a temporal basin filling model for Las Vegas Bay. The …

Small mammal and herpetofauna communities and habitat associations in foothills of the Chihuahuan Desert
… and adjacent uplands under 3 conditions of physiography: upper, middle, and lower. Sampling was conducted during late spring and early fall, 1993-94. Eighteen species of heteromyid and murid rodents were captured. Abundance decreased 34% over the term of this study and 14 of 42 temporal …

A Vegetative Analysis of Hercules Glades Wilderness
… Land Types established primarily on the basis of physiography and arboreal vegetation. Though the "cedar glades" did generally group together in the ordination models, no sub-set reflecting Ecological Land Types was apparent for arboreal or understory species. However, within the limits of this …

Heterogeneous Strain Distribution & the Effects of High Frequency Climate Change on the Evolution of Early-Stage Rift Systems: Case Studies from Lakes Tanganyika and Malawi (Nyasa), East Africa
… and rapid climate change on rift kinematics and physiography at scales <100 km, with few studies assessing the rift-regional (>100’s km) scale. In addition, there is limited information on how these processes influence rift physiography along strike and how these control the location and geometry …

Morphometric and genetic variation among populations of the southern short-tailed shrew, Blarina carolinensis, located along the Coastal Plain of Virginia
… carolinensis populations results from the unique physiography of Chesapeake Bay, namely peninsular water barriers, and that the intervening distribution of its congener, B. brevicuada, should promote morphometric and population differentiation due to isolation. Whether populations of B. …

Geomorphic and thermochronologic signatures of active tectonics in the central Nepalese Himalaya
… are characterized by a sharp transition in physiography that does not correlate with previously mapped faults. Rates of rock uplift, erosion, and exhumation for rocks surrounding this physiographic transition are investigated using digital topographic data, ⁴⁰Ar/³⁹Ar thermochronology, …

The influence of ridge geometry at the ultraslow-spreading Southwest Indian Ridge (9⁰-25⁰E) : basalt composition sensitivity to variations in source and process
… supersegments, this sharp contrast in geometry, physiography, and chemistry reflects "source" versus "process" dominated generation of basalt. Robust along-axis correlation of ridge characteristics (i.e. morphology, upwelling rate, lithospheric thickness), basalt chemistry, and crustal thickness …

Maritime resource exploitation in southwest Australia prior to 1901
… species in the region was determined by the physiography and climate. This relationship has always been imperfect, if not chaotic because of the unpredictability of the resources through long and short term cyclic phenomena. Control of access was the key to furthering economic and social …

Nesting Chronology of South Dakota Ducks
… with wetland habitat, temperature, and physiography were examined by multiple regression to see if these factors influenced nest initiation dates, Results of the analyses were inconclusive. There is probably not enough variation in most of these aspects across South Dakota to allow …
