Natural Dispersal

AbstractThe island fox (Urocyon littoralis) is one of few reportedly endemic terrestrial mammals on California's Channel Islands. Questions remain about how and when foxes first colonized the islands, with researchers speculating on a natural, human-assisted, or combined dispersal during the late Pleistocene and/or Holocene. A natural dispersal of foxes to the northern Channel Islands has been supported by reports of a few fox bones from late Pleistocene paleontological localities. Direct AMS 14C dating of these “fossil” fox bones produced dates ranging from ∼ 6400 to 200 cal yr BP, however, postdating human colonization of the islands by several millennia. Although one of these specimens is the earliest securely dated fox from the islands, these new data support the hypothesis that Native Americans introduced foxes to all the Channel Islands in the early to middle Holocene. However, a natural dispersal for the original island colonization cannot be ruled out until further paleontological, archaeological, and genetic studies (especially aDNA [ancient DNA]) are conducted.

San Clemente Island

Island foxes ( Urocyon littoralis (Baird, 1858)) have experienced severe reductions in populations on 4 out of 6 California Channel Islands. Although numbers of foxes on San Clemente Island (SCLI; Urocyon littoralis clementae Merriam, 1903) have remained relatively stable, data on reproductive success in urban and rural areas are necessary to better understand population dynamics of foxes and manage the population if it sustains declines. Determining locations and characteristics of den sites will also assist in minimizing possible impacts of humans on foxes. We found that 10 female foxes produced at least 19 kits during 2008. Female foxes that spent a greater proportion of time within an urban area had greater probability of reproducing compared with foxes that infrequently utilized urban areas. However, these “urban” foxes often selected den sites nearer to roads, which may expose them to increased mortalities. We located 23 den sites on a mean of 17°–18° slopes with 40% having westerly facing aspects. We recommend avoiding human disturbance to these areas from February through June, which may minimize potential impacts on foxes. Our study should provide insight into managing island foxes, especially in respect to urban areas on other Channel Islands.

Abstract Background With developing understanding that host-associated microbiota play significant roles in individual health and fitness, taking an interdisciplinary approach combining microbiome research with conservation science is increasingly favored. Here we establish the scat microbiome of the imperiled Channel Island fox (Urocyon littoralis) and look at the effects of geography and captivity on the variation in bacterial communities. Results Using high throughput 16S rRNA gene amplicon sequencing, we discovered distinct bacterial communities in each island fox subspecies. Weight, timing of the sample collection, and sex contributed to the geographic patterns. We uncovered significant taxonomic differences and an overall decrease in bacterial diversity in captive versus wild foxes. Conclusions Understanding the drivers of microbial variation in this system provides a valuable lens through which to evaluate the health and conservation of these genetically depauperate foxes. The island-specific bacterial community baselines established in this study can make monitoring island fox health easier and understanding the implications of inter-island translocation clearer. The decrease in bacterial diversity within captive foxes could lead to losses in the functional services normally provided by commensal microbes and suggests that zoos and captive breeding programs would benefit from maintaining microbial diversity.
