| | Title | Development of methods for estimating patch occupancy and patch-dynamic |
| | parameters from detection-nondetection survey data |
| | Project Description | This project involves research on field and statistical methods for estimating parameters relevant |
| | to animal patch occupancy using data on detection-nondetection of particular species from |
| | replicated (in time or space) surveys. In this project we will develop methods to estimate patch |
| | occupancy probabilities from presence/absence data collected during repeated visits to |
| | patches/areas. We will conduct simulations evaluating general models under several different |
| | sampling scenarios. An extension of these methods involves development of models that |
| | incorporate multiple species simultaneously for the purpose of addressing hypotheses about |
| | species co-occurrence. These models will permit the incorporation of habitat covariates into the |
| | models so that habitat can be factored out in a manner permitting inference about the species |
| | interactions. |
