Abstract/Summary

We describe biotic and abiotic factors that interact with field work to contribute to gradients in human-mediated herpetofaunal pathogen transmission (i.e., translocation) risk between sites. Using biotic and abiotic criteria, we identify site conditions that correspond to high risk for pathogen import [to a site] or high risk for pathogen export [from a site] for implementation of enhanced between-site biosecurity procedures to forestall human-mediated pathogen transmission. Our field-site criteria are based on seven contexts of the pathogen (occurrence, habitat), host(s) (occurrence, habitat, species richness), and geography (distance/topography, geopolitical land use) (Table 1). We do not provide an explicit decision tree because site contexts can be complex, and single contexts may be weighted heavily in some biosecurity decisions, warranting case-by-case decisions. A more conceptual decision tree (Fig. 1) about pathogen export or import can be more flexibly applied as site context vary. Our aim is to provide a rapid process to develop a qualitative narrative to support decisions for between-site herpetological disease biosecurity.
