This research aims to develop new models for capture-recapture studies that incorporate spatial information to improve density estimates of animal populations.
Developed likelihood-based capture-recapture models using spatial data from animal captures.
Estimated density as an explicit parameter, allowing straightforward evaluation of covariates.
Tested the method through simulations and applied it to estimate the density of Red-eyed Vireos.
Point estimators were found to be unbiased, and standard error estimators were almost unbiased.
Density estimates for Red-eyed Vireos were consistent with those obtained from existing spatial methods.
Additional spatially explicit models fitting successfully included temporal stratification and heterogeneous home ranges.
