“…Multiple data sources are usually combined using joint-likelihood methods (but see Pacifici et al, 2017) and often have the advantage of increased population parameter precision (Besbeas et al, 2002;Schaub & Abadi, 2011). Several data type combinations have been used in these joint models, including capture-recapture, count, and fecundity data (integrated models; i.e., Ahrestani, Saracco, Sauer, Pardieck, & Royle, 2017;Schaub & Abadi, 2011;Wilson, Gil-Weir, Clark, Robertson, & Bidwell, 2016), capture-recapture and census/count data (Catchpole, Freeman, Morgan, & Harris, 1998), radiotelemetry and capture-recapture data (Powell, Conroy, Hines, Nichols, & Krementz, 2000), count and detection/non-detection data (Zipkin et al, 2017), and capture-recapture and detection/ non-detection data (Freeman & Besbeas, 2012). In addition, recent advances with Bayesian hierarchical models have illustrated the utility of integrated data models (Schaub & Abadi, 2011;Schaub et al, 2007), and created opportunities for designing future studies incorporating multiple data sources.…”
