Abstract

Conservation breeding programmes include translocations of animals across breeding facilities, both in and ex situ, and to/from their natural habitat. Newly reintroduced Vancouver Island marmots (VIMs) originating from the captive breeding programme are known to experience high winter mortality once reintroduced. Whilst high winter mortality rates amongst reintroduced VIM populations remain a concern of unknown causes, this health issue could potentially be linked to changes in gut microbiota prior to hibernation. Furthermore, captivity is known to impact the gut microbiota of mammals that could be crucial for hibernation. In this study, we explored the diversity of bacterial communities in the gut of captive marmots during the entire active season, both kept in captivity at in situ and ex situ facilities, as well as free-ranging marmots during the summer period. Gut microbial diversity was higher in marmots held in ex situ facilities, outside of their habitat range, compared to captive marmots held within their habitat range, and in the wild, and differences in composition were also observed. In the entire active season, animals kept in the ex situ facility had increased abundance in taxa known to be mucin degraders, sulphate producers and possible cross-feeders, whilst an increase in fibre degraders of in situ and free-ranging marmots is potentially linked to diet variation between facilities. These results confirm the interest to transfer animals held at zoos to an in situ facility before relocation and expand our understanding of microbiota variation according to hibernation cycles in the context of conservation biology.

圈养条件对濒危冬眠动物的肠道微生物群很重要。
保护性繁殖计划包括动物在繁殖设施内和繁殖设施外的迁移,以及从自然栖息地到繁殖设施的迁移。新引进的温哥华岛旱獭(VIMs)来自人工繁殖计划,据了解,一旦重新引进,其冬季死亡率很高。虽然重新引入的温哥华岛旱獭冬季死亡率高的原因不明,但这一健康问题可能与冬眠前肠道微生物群的变化有关。此外,众所周知,人工饲养会影响哺乳动物的肠道微生物群,而肠道微生物群可能对冬眠至关重要。在这项研究中,我们探讨了圈养旱獭肠道细菌群落在整个活动季节的多样性,包括在原地和异地设施中圈养的旱獭,以及在夏季自由放养的旱獭。与栖息地范围内的圈养旱獭和野外的圈养旱獭相比,在栖息地范围外的非原地设施中饲养的旱獭肠道微生物多样性更高,而且还观察到微生物组成的差异。在整个活动季节,异地设施饲养的旱獭体内已知的粘蛋白降解类、硫酸盐生产类和可能的交叉摄食类的数量增加,而原地和野外饲养的旱獭体内纤维降解类的数量增加可能与不同设施之间的饮食差异有关。这些结果证实了将动物园饲养的动物转移到原地设施之前的重要性,并扩大了我们对保护生物学背景下冬眠周期微生物群变化的了解。

期刊介绍: Conservation Physiology is an online only, fully open access journal published on behalf of the Society for Experimental Biology. Biodiversity across the globe faces a growing number of threats associated with human activities. Conservation Physiology will publish research on all taxa (microbes, plants and animals) focused on understanding and predicting how organisms, populations, ecosystems and natural resources respond to environmental change and stressors. Physiology is considered in the broadest possible terms to include functional and mechanistic responses at all scales. We also welcome research towards developing and refining strategies to rebuild populations, restore ecosystems, inform conservation policy, and manage living resources. We define conservation physiology broadly and encourage potential authors to contact the editorial team if they have any questions regarding the remit of the journal.
