Natural perchlorate (ClO4−) is of increasing interest due to its wide-spread occurrence on Earth and Mars, yet little information exists on the relative abundance of ClO4− compared to other major anions, its stability, or long-term variations in production that may impact the observed distributions. Our objectives were to evaluate the...
Camera traps and mark-resight models: The value of ancillary data for evaluating assumptions
Arielle W. Parsons, Theodore R. Simons, Kenneth H. Pollock, Michael K. Stoskopf, Jessica J. Stocking, Allan F. O’Connell
2015, Journal of Wildlife Management (79) 1163-1172
Unbiased estimators of abundance and density are fundamental to the study of animal ecology and critical for making sound management decisions. Capture–recapture models are generally considered the most robust approach for estimating these parameters but rely on a number of assumptions that are often violated but rarely validated. Mark-resight models,...
An evaluation of a bed instability index as an indicator of habitat quality in mountain streams of the northwestern United States
Paul C. Kusnierz, Christopher Holbrook, David L. Feldman
2015, Environmental Monitoring and Assessment
Managers of aquatic resources benefit from indices of habitat quality that are reproducible and easy to measure, demonstrate a link between habitat quality and biota health, and differ between human-impacted (i.e., managed) and reference (i.e., nonimpacted or minimally impacted) conditions. The instability index (ISI) is an easily measured index that...
