英文摘要	The endangered San Joaquin kit fox (SJKF; Vulpes macrotis mutica) is strongly linked ecologically to xeric areas with high abundance of kangaroo rats. Endemic to the San Joaquin Desert of central California, the elusive nature of SJKF, coupled with steady habitat loss and lack of comprehensive surveys, has precluded efforts to quantify the species' population size and distribution, especially in the central and northern parts of its range. Because the Ciervo-Panoche Natural Area contains the largest area of high-quality habitat in this central/northern region, we conducted systematic transect surveys for SJKF scats with professionally trained dog-handler teams throughout the area during 2009-2011. We collected almost 600 scats over 473km of transects, documenting the freshness and location of each scat. Using molecular methods, we identified 93 SJKF individuals (56 males and 37 females) from 332 samples. Half of the individuals carried a mtDNA haplotype with a 16bp deletion that had not been previously detected in other areas surveyed. Four individuals were recaptured in 2010 and five in 2011, including one female that was captured every year. We documented a unique mtDNA haplotype and more individuals across a wider area of the Ciervo-Panoche Natural Area than expected. Population analyses revealed two distinct subpopulations, with low connectivity between foxes in the Panoche Valley that are separated by hills with unsuitable habitat from those on the adjacent valley floor next to a major Interstate highway (I-5). While individuals detected within 6km of each other were closely related, overall relatedness within each subpopulation approached zero. Genetic population models indicated a conservative population estimate of 90 kit foxes in total, with 60-90 individuals in the Panoche Valley and 17-27 individuals in the I-5 area. These results will help to inform management of the SJKF and identify areas that may be important to maintaining connectivity between populations.
