Scaling-up of CO2 fluxes to assess carbon sequestration in rangelands of Central Asia
Bruce K. Wylie, Tagir G. Gilmanov, Douglas A. Johnson, Nicanor Z. Saliendra, Larry L. Tieszen, Ruth Anne F. Doyle, Emilio Laca
2006, Conference Paper, Rangelands of central Asia: Proceedings of the conference on transformations, issues, and future challenges. RMRS-P-39
Flux towers provide temporal quantification of local carbon dynamics at specific sites. The number and distribution of flux towers, however, are generally inadequate to quantify carbon fluxes across a landscape or ecoregion. Thus, scaling up of flux tower measurements through use of algorithms developed from remote sensing and GIS data...
A review of methods to estimate cause-specific mortality in presence of competing risks
Dennis M. Heisey, Brent R. Patterson
2006, Journal of Wildlife Management (70) 1544-1555
Estimating cause-specific mortality is often of central importance for understanding the dynamics of wildlife populations. Despite such importance, methodology for estimating and analyzing cause-specific mortality has received little attention in wildlife ecology during the past 20 years. The issue of analyzing cause-specific, mutually exclusive events in time is not unique...
