Abstract:
|
Classical capture-recapture (CR) models are widely used to estimate the apparent survival of species in ecology. However, classical CR models are unable to accommodate spatially explicit processes and thus do not account for the spatial distribution of individuals. The development of spatial capture-recapture (SCR) models incorporate an explicit model for the spatial distribution allowing the ecologists to test hypotheses, including spatial information that is inherent in ecological studies. Recent developments include integrating SCR and other ecological survey data into a unified modeling framework to obtain useful inferences on demographic parameters with reduced uncertainty and enhanced statistical power. In our approach, we introduce a unified modeling framework integrating SCR and distance sampling by incorporating the spatial distribution. We evaluate the performance of the proposed approach using both simulated data and real data on grasshopper sparrows in Konza Prairie Biological Station, Kansas.
