Abstract:
Understanding changes over time in the distribution of interacting native and invasive species that may be symptomatic of competitive exclusion is critical to identify the need for and effectiveness of management interventions. Occupancy models greatly increase the robustness of inference that can be made from presence/absence data when species are imperfectly detected, and recent novel developments allow for the quantification of the strength of interaction between pairs of species. We used a two-species multi-season occupancy model to quantify the impact of the invasive American mink on the native European mink in Spain through the analysis of their co-occurrence pattern over twelve years (2000 - 2011) in the entire Spanish range of European mink distribution, where both species were detected by live trapping but American mink were culled. We detected a negative temporal trend in the rate of occupancy of European mink and a simultaneous positive trend in the occupancy of American mink. The species co-occurred less often than expected and the native mink was more likely to become extinct from sites occupied by the invasive species. Removal of American mink resulted in a high probability of local extinction where it co-occurred with the endemic mink, but the overall increase in the probability of occupancy over the last decade indicates that the ongoing management is failing to halt its spread. More intensive culling effort where both species co-exist as well as in adjacent areas where the invasive American mink is found at high densities is required in order to stop thedecline of European mink.

Comment:
Data were gathered from live-trapping surveys conducted between 2000 and 2011 in Northern Spain as part of European mink conservation plan and American mink control plan implemented by technicians of regional governments coordinated by the Spanish Ministry of Agriculture, Food and Environment.
Data are detection histories used in a two-species multi-season occupancy analysis: the trapping events have been grouped into annual primary sampling occasions (each year from 2000 to 2011) that included two secondary periods (January - March and September - December). The sites surveyed were cells of 10x10km.
