Incorporating Telemetry Information Into Capture-Recapture Analyses Improves Precision and Accuracy Ofabundance Estimates Given Spatiotemporally Biasedrecapture Effort

We demonstrate a simple technique to incorporate two additional streams of data on the same population.

Peer-Reviewed Research|

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 maximise encounters, sampling efforts may be largely opportunistic or biased to accessible areas. The resulting sparse and spatially biased data may be difficult to model, standardise 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 synthesised to reveal important ecological processes.
