阿马戈萨田鼠是一种高度濒危的啮齿动物，是加利福尼亚州伊尼奥县阿马戈萨河流域一小段地区的特有种。它专注于自然界中单一的、营养不足的食物来源。作为保护该物种的努力的一部分，建立了圈养繁殖种群，作为保险群体，并在恢复栖息地可用时将其释放到野外。该群体已成功地以商业饮食维持了多代，但人们担心群体动物可能会失去消化野生饮食所需的肠道微生物。我们分析了群体饲养的和最近捕获的各种饮食的野生田鼠的粪便，以及群体和野生田鼠的前肠内容物。出乎意料的是，尽管饮食截然不同，但粪便微生物组成并没有太大差异，并且观察到的差异主要是低丰度微生物。相比之下，群体田鼠前肠微生物组以 Allobaculum sp. 为主。而野生前肠以乳杆菌为主。如果这些细菌群落差异导致消化方面有益的功能差异，那么圈养饲养的阿马戈萨田鼠应在释放到野外之前进行准备，以尽量减少或消除这些差异，从而最大限度地提高其成功机会。
The Amargosa vole is a highly endangered rodent endemic to a small stretch of the Amargosa River basin in Inyo County, California. It specializes on a single, nutritionally marginal food source in nature. As part of a conservation effort to preserve the species, a captive breeding population was established to serve as an insurance colony and a source of individuals to release into the wild as restored habitat becomes available. The colony has successfully been maintained on commercial diets for multiple generations, but there are concerns that colony animals could lose gut microbes necessary to digest a wild diet. We analyzed feces from colony-reared and recently captured wild-born voles on various diets, and foregut contents from colony and wild voles. Unexpectedly, fecal microbial composition did not greatly differ despite drastically different diets and differences observed were mostly in low-abundance microbes. In contrast, colony vole foregut microbiomes were dominated by Allobaculum sp. while wild foreguts were dominated by Lactobacillus sp. If these bacterial community differences result in beneficial functional differences in digestion, then captive-reared Amargosa voles should be prepared prior to release into the wild to minimize or eliminate those differences to maximize their chance of success.
