Comparing the bacterial communities of wild and captive golden mantella frogs: Implications for amphibian conservation.

ABSTRACT: Bacterial communities are frequently found in symbiotic associations with most animal species. The characteristically moist amphibian skin provides a good environment for the growth of some species of bacteria; among these a few can act as a first line defense mechanism against infections. Amphibians in the wild have relatively high exposure to bacteria through environmental transmission and through interactions with different conspecifics, whilst in captivity animals interact with fewer individuals, as well as experiencing a less complex environment through which to obtain their bacterial community. Here we compared the skin microbiota of captive and wild Mantella aurantiaca to investigate whether the captive environment was affecting individuals' skin associated bacteria. This could have survivorship implications if captive animals had a different skin microbial community in comparison to wild counterparts and they were to be used in a reintroduction program. The microbial community were characterized through 16S rRNA amplicon sequencing methodology. Analyses showed that captive individuals had significantly lower diversity of bacterial species and lower relative abundant microbiota when compared to wild populations; this could result in captive frogs released back to the wild probably has greater susceptibility to infections due to inadequate skin microbiota.

Project description:Understanding the mechanisms of how urbanization influences the evolution of native species is vital for urban wildlife ecology and conservation in the Anthropocene. With thousands of years of agriculture-dominated historical urbanization followed by 40 years of intensive and rapid urbanization, Shanghai provides an ideal environment to study how the two-stage urbanization process influences the evolution of indigenous wildlife, especially of anuran species. Therefore, in this study, we used mitochondrial Cyt-b gene, microsatellite (SSR), and single nucleotide polymorphism (SNP) data to evaluate the demographic history and genetic structure of the eastern golden frog (Pelophylax plancyi), by sampling 407 individuals from 15 local populations across Shanghai, China. All local populations experienced bottlenecks during historical urbanization, while the local populations in urban areas maintained comparable contemporary effective population sizes (N e) and genetic diversity with suburban and rural populations. Nevertheless, the rapid modern urbanization has already imposed significant negative effects to the integrity of populations. The 15 local populations were differentiated into eight genetic clusters, showing a spatial distribution pattern consistent with the current urbanization gradient and island-mainland geography. Although moderate gene flow still occurred from the rural peripheral cluster to urban and suburban clusters, population fragmentation was more serious in the urban and suburban populations, where higher urbanization levels within 2-km radius areas showed significant negative relationships to the N e and genetic diversity of local populations. Therefore, to protect urban wildlife with limited dispersal ability, improving conditions in fragmented habitat remnants might be most essential for local populations living in more urbanized areas. Meanwhile, we highlight the need to preserve large unfragmented rural habitats and to construct corridor networks to connect discrete urban habitat remnants for the long-term wildlife conservation in intensively urbanizing environments.
