“…The phylum-level bacterial diversity and abundance associated with T. metcalfi was consistent with other freshwater snails including viviparids, Pomacea canaliculata , and Potamopyrgus antipodarum (Li et al, 2019; Bankers et al, 2020; North and Minton, 2021). The core microbiome of T. metcalfi was consistent with a benthic organism living in a desert freshwater environment.…”

The Chihuahuan Desert swamps are a hotspot for imperiled organisms including freshwater springsnails and bacteria. Many of these taxa are endemic to the desert and to the individual waterbodies where they occur. Efforts to conserve diversity in these threatened areas must account for the life history of the organisms, but also interactions between organisms including microbes. We documented the microbial assemblage associated with Tryonia metcalfi, a critically imperiled freshwater snail endemic to a ciénega system in western Texas. We identified 14 bacterial families in our snail samples and determined a core assemblage of 19 bacterial taxa (4 of which represented novel lineages) that are likely dependent on the snail. Future conservation efforts involving T. metcalfi and its environment should therefore consider the microbial diversity associated with both the snail and the ciénegas.

“…Second, when considering free-ranging European mink in their natural habitat, they could be more likely to select specific gut bacterial taxa because of their shared coevolutionary history with the environmental microbes in western France (Bankers et al, 2021). On the other hand, the invasive American mink may lack host-microbes coevolutionary history with native bacteria and would thus be less likely to retain newly acquired microbes when becoming feral.…”

One of the threats that the critically endangered European mink (Mustela lutreola) faces throughout its relict range, including the occidental population, is the impact of the American mink (Mustela vison) invasion in its natural habitat. We aimed to explore the differences in microbiota and genetic diversity between European and American mink to test phylosymbiosis theory. We investigated the gut microbiota composition of European and American mink in a controlled environment (captive breeding compounds and fur farms respectively) to account for the impact of the environment on gut bacterial composition. We compared them to the gut microbiota of both mink species in the natural environment across multiple habitats. Our exploratory results showed differences between free-ranging and captive individuals, with more extreme changes in American mink 2 compared to European mink. However, feral American mink from a long-established population exhibited gut bacterial composition closer to the free-ranging native species compared to more recently established feral populations. This result could be explained by dietary shifts in the area sampled based on prey availability through different landscape, but also to a lesser extent due to greater genetic differentiation. This exploratory work contributes to the scarce literature currently available on the dynamics between gut microbiota and mammal invasion.

“…The New Zealand mud snail Potamopyrgus antipodarum is an unusual organism from Aotearoa in that it has been a successful intruder in foreign ecosystems and is now considered an invasive pest in Europe. In their invasive range, these snails form novel microbial relationships, with a core microbiome comprising some 30 microbial taxa (Bankers et al 2021). The singular core taxon found in New Zealand resident snails (Arenimonas) is retained by the invasive snails (Bankers et al 2021).…”

The singular core taxon found in New Zealand resident snails (Arenimonas) is retained by the invasive snails (Bankers et al 2021).

“…Significant differences in bacterial community composition occur between sexually and asexually reproducing snails, the former of which hosts Rickettsiales bacteria, and the latter Rhodobacter. This paper did discuss the need for additional work, due to some uncertainty around phylogeography, but it is interesting to consider that invasive lines of snails in Europe and North America reproduce asexually, and have distinct differences in microbiomes (Takacs-Vesbach et al 2016;Bankers et al 2021).…”

Microbiome research is revealing the profound effects that microbial inhabitants can have on their animal hosts. Recent and rapid advances in sequencing technologies have allowed biologists to characterise the microbial constituents of a variety of host organisms, giving greater insights into these intimate relationships than ever before. For many animal species, microbiomes serve as an interface between host and environment, with associated microorganisms playing functional roles in nutrition, immunity, reproduction, and even behaviour. In this Review, we offer a brief overview of microbiome research methodology before summarising previous and ongoing research into the microbiomes of native New Zealand animals. Our unique endemic fauna, evolved during tens of millions of years of geographic isolation, offers exciting opportunities for microbiome research across a range of diverse taxa and we highlight key findings of relevant studies. Moreover, while recognising the crucial role that 16S rRNA gene sequencing plays in microbiome research, we conclude the Review with a look beyond 16S and consider what other technologies can bring to this field. We encourage further investigation into the functional roles of microbial species across a broader range of host-animal taxa across New Zealand, both in wild and captive states.

Invasive freshwater snails form novel microbial relationships

Abstract: All organisms are home to numerous microbes. The relationship between hosts and their microbial communities (microbiota) can play a role in key host functions (Archie & Theis, 2011; Brucker
