Workshop organiser: Joanne Potts, The Analytical Edge, TAS.
This workshop is aimed at people collecting and analysing capture-recapture data to estimate density of a target population, where a portion of the population can be uniquely identified. This includes proximity traps (e.g., camera traps), multi-catch traps (e.g., mist nets) or single-catch traps. No background knowledge in capture-recapture analyses is required, since the workshop will cover introductory concepts. The workshop will be conducted in R, and although code will be provided with complete worked examples, familiarity with R will help participants gain more from the workshop.
This workshop will cover the following:
– motivation for using spatial capture-recapture
– theoretical understanding of how the spatial capture-recapture likelihood works (in pictures!)
– a practical in class during which participants collect spatial capture-recapture data
– learn how to store, format and import spatial capture-recapture data
– analyse data collected during the morning session, including using ‘masks’ to define habitat from non-habitat, exploring the form of the capture function, the use of covariates, and model selection
