Risk assessments are needed to understand the implications of reported concentrations; a fundamental part of the...
Identifying major sedimentary basins beneath the West Antarctic ice sheet from aeromagnetic data analysis
Robin E. Bell, M. Studinger, G.D. Karner, Carol A. Finn, D. D. Blankenship
Dieter Karl Futterer, Detlef Damaske, Georg Kleinschmidt, Hubert Miller, Franz Tessensohn, editor(s)
2005, Book chapter, Antarctica: Contributions to global earth sciences
In the Ross Sea, large sedimentary basins reflect primarily the major extensional event associated with the Late Cretaceous breakup of Gondwana. Within the Interior Ross Embayment, no similar large basins have been identified to date. We have used aerogravity and Werner deconvolution methods applied to aeromagnetic data to map depth...
A retrospective perspective: evaluating population changes by repeating historic bird surveys
Lawrence D. Igl, Douglas H. Johnson
2005, General Technical Report GTR-PSW-191
Acquiring an accurate picture of the changes in bird populations often involves a tradeoff between the time and effort required to complete the surveys and the number of years spent surveying the bird populations. An alternative approach to long-term monitoring efforts is to collect current data and contrast those with...
Population genetic analysis of Mountain Plover using mitochondrial DNA sequence data
S.J. Oyler-McCance, J. St. John, F.L. Knopf, T.W. Quinn
2005, The Condor (107) 353-362
Mountain Plover (Charadrius montanus) distribution and abundance have been reduced drastically in the past 30 years and the conversion of shortgrass prairie to agriculture has caused breeding populations to become geographically isolated. This, coupled with the fact that Mountain Plovers are thought to show fidelity to breeding grounds, leads to...

Phillip J. van Mantgem, Nathan L. Stephenson
2005, Journal of Ecology (93) 737-747
1 We assess the use of simple, size-based matrix population models for projecting population trends for six coniferous tree species in the Sierra Nevada, California. We used demographic data from 16 673 trees in 15 permanent plots to create 17 separate time-invariant, density-independent population...

S. M. Louda, T. A. Rand, A. E. Arnett, A. S. McClay, A. K. McEachern
2005, Ecological Applications (15) 234-249
Controversy exists over estimation of ecological risk in biological control. At present, the risk to the rare, federally listed Pitcher's thistle (Cirsium pitcheri) in North America from Rhinocyllus conicus, a biological control weevil now feeding on many native thistles, is unknown. We hypothesized that quantification of host specificity and potential...
Forest turnover rates follow global and regional patterns of productivity
Nathan L. Stephenson, Phillip J. van Mantgem
2005, Ecology Letters (8) 524-531
Using a global database, we found that forest turnover rates (the average of tree mortality and recruitment rates) parallel broad-scale patterns of net primary productivity. First, forest turnover was higher in tropical than in temperate forests. Second, as recently demonstrated by others, Amazonian forest turnover was higher on fertile than...

Erik A. Beever, David A. Pyke, Jeanne C. Chambers, Fred Landau, S.D. Smith
2005, Western North American Naturalist (65) 382-402
Disturbance in riparian areas of semiarid ecosystems involves complex interactions of pulsed hydrologic flows, herbivory, fire, climatic effects, and anthropogenic influences. We resampled riparian vegetation within ten 10-m × 100-m plots that were initially sampled in 1992 in 4 watersheds of the Snake Range, east central Nevada. Our finding of...
