The Importance of Habitat Shape and Landscape Context to Northern Bobwhite Populations (2008)
Jason D. Riddle, Christopher E. Moorman, Kenneth H. Pollock
Northern bobwhite (Colinus virginianus) populations have declined nationally for at least the past 4 decades. Field borders have been promoted as an important component of conservation plans to...
A Comparison of Methods for Estimating Northern Bobwhite Covey Detection Probabilities (2008)
Jason D. Riddle, Christopher E. Moorman, Kenneth H. Pollock
We compared the time-of-detection and logistic regression methods of estimating probability of detection for northern bobwhite (Colinus virginianus) coveys. Both methods are unusual in that they...
Krishna Pacifici, Theodore R. Simons, Kenneth H. Pollock
We used a bird-song simulation system to experimentally assess the effects of habitat, vegetation structure, and background noise on detection probability in aural avian point counts. We simulated...

A Field Evaluation of Distance Measurement Error in Auditory Avian Point Count Surveys (2007)
MATHEW W. ALLDREDGE, THEODORE R. SIMONS, KENNETH H. POLLOCK
Detection distance is an important and common auxiliary variable measured during avian point count surveys. Distance data are used to determine the area sampled and to model the detection process...
Estimation of Detection Probability in Manatee Aerial Surveys at a Winter Aggregation Site (2007)
HOLLY H. EDWARDS, KENNETH H. POLLOCK, BRUCE B. ACKERMAN, JAMES A. POWELL
Estimating components of detection probability is crucial to improving the design of aerial surveys for wildlife populations, and this is especially true for species of marine mammals that are...
EXPERIMENTAL ANALYSIS OF THE AUDITORY DETECTION PROCESS ON AVIAN POINT COUNTS (2007)

Comparing Population Size Estimators for Plethodontid Salamanders (2004)
Larissa L. Bailey, Theodore R. Simons, Kenneth H. Pollock
Despite concern over amphibian declines, few studies estimate absolute abundances because of logistic and economic constraints and previously poor estimator performance. Two estimation approaches...
LARISSA L. BAILEY, THEODORE R. SIMONS, KENNETH H. POLLOCK
Recent concern over global amphibian population declines has highlighted a need for more extensive, rigorous monitoring programs. Two sources of variation, spatial variation and variation in...
LARISSA L. BAILEY, THEODORE R. SIMONS, KENNETH H. POLLOCK
Recent worldwide amphibian declines have highlighted a need for long-term, large-scale monitoring programs. Scientific or management objectives, appropriate spatial sampling, and detectability all...

Since its founding, NASA has been dedicated to the advancement of aeronautics and space science. The NASA Scientific and Technical Information (STI) Program Office plays a key part in helping NASA...
Higher temporal variability of forest breeding bird communities in fragmented landscapes
Boulinier, Thierry, Nichols, James D., Hines, James E., Sauer, John R., Flather, Curtis H., Pollock, Kenneth H.
Understanding the relationship between animal community dynamics and landscape structure has become a priority for biodiversity conservation. In particular, predicting the effects of habitat...

Many authors have shown that a combined analysis of data from two or more types of recapture survey brings advantages, such as the ability to provide more information about parameters of interest....
The use of auxiliary variables in capture-recapture modelling: an overview
I review the use of auxiliary variables in capture-recapture models for estimation of demographic parameters (e.g. capture probability, population size, survival probability, and recruitment,...
