2005, Book chapter, Wildlife diseases: Landscape epidemiology, spatial distribution and utilization of remote sensing technology
Few diseases are reported in salamanders. Two notable exceptions are infections by Ranavirus and Ichthyophonus. Except for mortality events associated with ranaviruses in tiger salamanders (Ambystoma tigrinum) and spotted salamanders (A. maculatum), dieoffs of salamanders are rarely detected or reported. Diseases presented in this chapter are those encountered in free-living...
Factors affecting plant diversity during postfire recovery and succession of mediterranean-climate shrublands in California, USA
Jon E. Keeley, C. J. Fotheringham, Melanie Baer-Keeley
2005, Diversity and Distributions (11) 535-537
Plant community diversity, measured as species richness, is typically highest in the early post-fire years in California shrublands. However, this generalization is overly simplistic and the present study demonstrates that diversity is determined by a complex of temporal and spatial effects. Ninety sites distributed across southern California were studied for...

Nearshore wave-induced cyclical flexing of sea cliffs
P.N. Adams, C. D. Storlazzi, R. Scott Anderson
2005, Journal of Geophysical Research F: Earth Surface (110)
[1] Evolution of a tectonically active coast is driven by geomorphically destructive energy supplied by ocean waves. Wave energy is episodic and concentrated; sea cliffs are battered by the geomorphic wrecking ball every 4-25 s. We measure the response of sea cliffs to wave assault by sensing the ground motion...

Some geometric constraints on ring-width trend
Richard L. Phipps
2005, Tree-Ring Research (61) 73-76
Simulations of tree rings from trees of undisturbed forest sites are used to describe natural, long-term width trends. Ring-width trends of canopy-sized white oak are simulated from regressions of BAI(ring area) data of real trees. Examples are given of a tree from a typical re-growth forest in Illinois and of a...
Osmium isotope stratigraphy of a marine ferromanganese crust
V. Klemm, S. Levasseur, M. Frank, J.R. Hein, A. N. Halliday
2005, Earth and Planetary Science Letters (238) 42-48
Ferromanganese crusts provide records of long term change in ocean circulation and continental weathering. However, calibrating their age prior to 10 Ma has been entirely based on empirical growth rate models using Co concentrations, which have inherently large uncertainties and fail to detect hiatuses and erosional events. We present a...
Drainage networks after wildfire
D.A. Kinner, J. A. Moody
2005, International Journal of Sediment Research (20) 194-201
Predicting runoff and erosion from watersheds burned by wildfires requires an understanding of the three-dimensional structure of both hillslope and channel drainage networks. We investigate the small-and large-scale structures of drainage networks using field studies and computer analysis of 30-m digital elevation model. Topologic variables were derived from a composite...

Stephen J. Dinsmore, Fritz L. Knopf
2005, Canadian Field-Naturalist (119) 532-536
We studied chick survival of the Mountain Plover (Charadrius montanus) in Montana and found that chicks tended by females had higher survival rates than chicks tended by males, and that chick survival generally increased during the nesting season. Differences in chick survival were most pronounced early in the nesting season,...
Statistical analysis of water-quality data containing multiple detection limits: S-language software for regression on order statistics
L. Lee, D. Helsel
2005, Computers & Geosciences (31) 1241-1248
Trace contaminants in water, including metals and organics, often are measured at sufficiently low concentrations to be reported only as values below the instrument detection limit. Interpretation of these "less thans" is complicated when multiple detection limits occur. Statistical methods for multiply censored, or multiple-detection limit, datasets have been developed...

Hydrologic changes in urban streams and their ecological significance
C.P. Konrad, D. B. Booth
2005, American Fisheries Society Symposium (2005) 157-177
Urban development modifies the production and delivery of runoff to streams and the resulting rate, volume, and timing of streamflow. Given that streamflow demonstrably influences the structure and composition of lotic communities, we have identified four hydrologic changes resulting from urban development that are potentially significant to stream ecosystems: increased...
