ct: Camera Trap Data Management and Multi-Method Ecological Analysis

Description

Tools for the complete camera trap data workflow in wildlife monitoring and ecological research. Reads and edits media metadata, filters independent detections, and standardises records for analysis. Measures diel activity and overlap (Ridout and Linkie (2009) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1198/jabes.2009.08038")}), directed short-term association between species with an encounter-response model (Hawkes (1971) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1093/biomet/58.1.83")}), seasonal shifts in activity, spatial coverage of detections, and species diversity. Estimates density or abundance of unmarked populations with several methods, including the random encounter model, camera trap distance sampling, time-to-event, space-to-event, instantaneous sampling, and the random encounter and staying-time model (see Rowcliffe et al. (2008) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1111/j.1365-2664.2008.01473.x")}, Howe et al. (2017) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1111/2041-210X.12790")}, Moeller et al. (2018) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1002/ecs2.2331")}, and Nakashima et al. (2018) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1111/1365-2664.13059")}).
