Small-mammal density estimation: A field comparison of grid-based vs. web-based density estimators
Robert R. Parmenter,Terry L. Yates,David E. Anderson,Kenneth P. Burnham,Jonathan L. Dunnum,Alan B. Franklin,Michael T. Friggens,Bruce C. Lubow,Michael W. Miller,Gail S. Olson,Cheryl A. Parmenter,John R. Pollard,Eric A. Rexstad,Tanya M. Shenk,Thomas R. Stanley,Gary C. White +15 more
TL;DR: In this paper, two general classes of density estimation models have been developed: models that use data sets from capture-recapture or removal sampling techniques (often derived from trapping grids) from which separate estimates of population size (N) and effective sampling area (Â) are used to calculate density (D = N/Â), and models applicable to sampling regimes using distance-sampling theory (typically transect lines or trapping webs) to estimate detection functions and densities directly from the distance data.

Modeling of site occupancy dynamics for northern spotted owls, with emphasis on the effects of barred owls
Gail S. Olson,Robert G. Anthony,Eric D. Forsman,Steven H. Ackers,Peter J. Loschl,Janice A. Reid,Katie M. Dugger,Elizabeth M. Glenn,William J. Ripple +8 more
TL;DR: In this article, the authors considered the imperfect and variable detectability of spotted owls and allowed modeling of temporal variation in site occupancy, extinction, and colonization probabilities, and examined the effects of barred owl presence on these parameters.
The effects of habitat, climate, and Barred Owls on long-term demography of Northern Spotted Owls

Bailey,Darren A. Clark,Steven H. Ackers,Lawrence S. Andrews,Benjamin Augustine,Brian L. Biswell,Jennifer A. Blakesley,Peter C. Carlson,Matthew J. Clement,Lowell V. Diller,Elizabeth M. Glenn,Adam W. Green,Scott A. Gremel,Dale R. Herter,J. Mark Higley,Jeremy Hobson,Rob B. Horn,Kathryn P. Huyvaert,Christopher McCafferty,Trent L. McDonald,Kevin McDonnell,Gail S. Olson,Janice A. Reid,Jeremy T. Rockweit,Viviana Ruiz,Jessica Saenz,Stan G. Sovern +37 more
TL;DR: Strong support is found for a negative effect of Barred Owl presence on apparent survival of Spotted Owls in 10 of 11 study areas, but found few strong effects of habitat on survival at the study area scale; however, there was little consistency among areas regarding the relative importance of specific climate covariates.
Modeling demographic performance of northern spotted owls relative to forest habitat in oregon
Gail S. Olson,Elizabeth M. Glenn,Robert G. Anthony,Eric D. Forsman,Janice A. Reid,Peter J. Loschl,William J. Ripple +6 more
TL;DR: In this paper, the authors developed statistical models relating owl survival and productivity to forest cover types within the Roseburg Study Area in the Oregon Coast Range of Oregon, USA, and combined these demographic parameters using a Leslie-type matrix to obtain an estimate of habitat fitness potential for each owl territory (n = 94).

Local weather, regional climate, and annual survival of the northern spotted owl
TL;DR: In this article, the authors used an information-theoretical approach and Cormack-Jolly-Seber models for open populations in program MARK to examine relationships between survival rates of Northern Spotted Owls and a variety of local weather variables and long-term climate variables.
