Potential distribution and conservation implications of key marsupials for the Patagonian temperate forest

Abstract

The Monitos del monte (genus Dromiciops) are endemic marsupials displaying a key ecological role inside the Patagonian temperate forest, a region of hotspot for biodiversity. Here, we predicted the potential distribution of D. gliroides and D. bozinovici and evaluated their conservation issues by quantifying the protected surface of both species. We found that Annual precipitation, Precipitation of Warmest Quarter and Precipitation Seasonality, Max Temperature of Warmest Month and Isothermality were the main environmental determinants in the models. Each species showed particular requirements, suggesting an environmental niche partitioning. On the other hand, we found that only 15% of the total potential distribution area for D. bozinovici and 24% for D. gliroides are currently protected. Although both species are threatened by habitat loss and degradation, the current situation for D. bozinovici is more critical. Overall, our study provides useful information for the management of the most critical areas for Dromiciops conservation.
