| intraspecific variation in the skin-associated microbiome of a terrestrial salamander. | resident microbial communities living on amphibian skin can have significant effects on host health, yet the basic ecology of the host-microbiome relationship of many amphibian taxa is poorly understood. we characterized intraspecific variation in the skin microbiome of the salamander ensatina eschscholtzii xanthoptica, a subspecies composed of four genetically distinct populations distributed throughout the san francisco bay area and the sierra nevada mountains in california, usa. we found that ... | 2017 | 28466089 |
| pronounced phylogeographic structure on a small spatial scale: geomorphological evolution and lineage history in the salamander ring species ensatina eschscholtzii in central coastal california. | the salamander ensatina eschscholtzii is a classic example of a ring species, and has an intricate biogeographic history. within a part of the ring distribution, earlier work using allozymes disclosed high levels of genetic structure in central coastal california, where the subspecies oregonensis, xanthoptica, and eschscholtzii meet. we used mitochondrial cytochrome b sequences to further examine patterns of divergence in this area, including data from 155 localities (309 individuals). our focus ... | 2009 | 19026754 |
