Incorporating Telemetry Information Into Capture-Recapture Analyses Improves Precision and Accuracy of Abundance Estimates Given Spatiotemporally Biased Recapture Effort
September 18, 2024
We demonstrate a simple technique to incorporate two additional streams of data on the same population.
Natural populations that are rare, cryptic or inaccessible provide a monumental challenge to monitoring, as adequate data are extremely difficult to collect. Surveys often encompass only a small portion of a population's range due to difficult terrain or inclement weather, especially for populations with extensive ranges. Thus, to maximize encounters, sampling efforts may be largely opportunistic or biased to accessible areas. The resulting sparse and spatially biased data may be difficult to model, standardize across years and incorporate into an assessment or management framework. However, in many monitoring programs, there are usually multiple threads of data that, though each may have its own limitations, can be synthesized to reveal important ecological processes.
