V.L. Boyarski, G.H. Rodda, J. A. Savidge
2007, Journal of Wildlife Management (71) 1704-1707
We conducted a physical simulation experiment to test the efficacy of harmonic direction finding for remotely detecting locomotor activity in animals. The ability to remotely detect movement helps to avoid disturbing natural movement behavior. Remote detection implies that the observer can sense only a change in signal bearing. In our...
Activity budgets derived from time-depth recorders in a diving mammal
James L. Bodkin, Daniel H. Monson, George G. Esslinger
2007, Journal of Wildlife Management (71) 2034-2044
We describe a method to convert continuously collected time–depth data from archival time–depth recorders (TDRs) into activity budgets for a benthic-foraging marine mammal. We used data from 14 TDRs to estimate activity-specific time budgets in sea otters (Enhydra lutris) residing near Cross Sound, southeast Alaska, USA. From the TDRs we...

J.D. Nichols, J.E. Hines, D.I. MacKenzie, M.E. Seamans, R. J. Gutierrez
2007, Ecology (88) 1395-1400
The distribution of a species over space is of central interest in ecology, but species occurrence does not provide all of the information needed to characterize either the well-being of a population or the suitability of occupied habitat. Recent methodological development has focused on drawing inferences about species occurrence in...
Spatial models of Northern Bobwhite populations for conservation planning
Daniel J. Twedt, R. Randy Wilson, Amy S. Keister
2007, Journal of Wildlife Management (71) 1808-1818
Since 1980, northern bobwhite (Colinus virginianus) range-wide populations declined 3.9% annually. Within the West Gulf Coastal Plain Bird Conservation Region in the south-central United States, populations of this quail species have declined 6.8% annually. These declines sparked calls for land use change and prompted implementation of various conservation...
Population influences on tornado reports in the United States
C.J. Anderson, C. K. Wikle, Q. Zhou, J. Andrew Royle
2007, Weather and Forecasting (22) 571-579
The number of tornadoes reported in the United States is believed to be less than the actual incidence of tornadoes, especially prior to the 1990s, because tornadoes may be undetectable by human witnesses in sparsely populated areas and areas in which obstructions limit the line of sight. A hierarchical...
Climatic variation and the distribution of an amphibian polyploid complex
C.R.V. Otto, J.W. Snodgrass, D.C. Forester, J.C. Mitchell, R.W. Miller
2007, Journal of Animal Ecology (76) 1053-1061
1. The establishment of polyploid populations involves the persistence and growth of the polyploid in the presence of the progenitor species. Although there have been a number of animal polyploid species documented, relatively few inquiries have been made into the large-scale mechanisms of polyploid establishment in animal groups. Herein we...
Analysis of multinomial models with unknown index using data augmentation
J. Andrew Royle, R.M. Dorazio, W.A. Link
2007, Journal of Computational and Graphical Statistics (16) 67-85
Multinomial models with unknown index ('sample size') arise in many practical settings. In practice, Bayesian analysis of such models has proved difficult because the dimension of the parameter space is not fixed, being in some cases a function of the unknown index. We describe a data augmentation approach...
Mapping the information landscape: Discerning peaks and valleys for ecological monitoring
L.J. Moniz, J.D. Nichols, J.M. Nichols
2007, Journal of Biological Physics (33) 171-181
We investigate previously unreported phenomena that have a potentially significant impact on the design of surveillance monitoring programs for ecological systems. Ecological monitoring practitioners have long recognized that different species are differentially informative of a system's dynamics, as codified in the well-known concepts of indicator or keystone species. Using a...
A Bayesian state-space formulation of dynamic occupancy models
J. Andrew Royle, M. Kery
2007, Ecology (88) 1813-1823
Species occurrence and its dynamic components, extinction and colonization probabilities, are focal quantities in biogeography and metapopulation biology, and for species conservation assessments. It has been increasingly appreciated that these parameters must be estimated separately from detection probability to avoid the biases induced by nondetection error. Hence, there is...
