“…The SMARC captive riffle beetle environment consists of a series of opaque plastic containers customized with PVC fittings to provide fresh flowing, non-recirculated Edwards (Balcones Fault Zone) Aquifer well water between 21-23 °C and filled with a layer of conditioned leaves, rocks, and wood as biofilm food sources (Huston & Gibson, 2015). Leaves, rocks, and wood are collected from the riparian area directly above or near H. comalensis habitat.…”

“…Despite the higher bacterial diversity of the captive beetle microbiomes, their microbiomes are more similar to each other in composition compared to the wild beetle microbiomes based on the nMDS (Figure 3). The wild beetle microbiomes individually had lower diversity, but differed more from one another according to the distance between groups in the nMDS, which could be due to increased physical distances between beetles and variation in the environment (Huston & Gibson, 2015, Ajani et al, 2018, Haworth et al, 2019. One study found that the gut of captive rhinoceroses has a higher bacterial diversity attributed to contact with humans and interaction with man-made environments (McKenzie et al, 2017).…”

The gut microbiome is affected by host intrinsic factors, diet, environment, and strongly linked to host's health. Although fluctuations of microbiome composition are normal, some are due to changes in host environmental conditions. When species are moved into captive environments for conservation, education, or rehabilitation, these new conditions can influence a change in gut microbiome composition. Here, we compared the microbiomes of wild and captive Comal Springs riffle beetles (Heterelmis comalensis) by using amplicon sequencing of the 16S rRNA gene. We found that the microbiome of captive beetles was more diverse than wild beetle microbiomes. We identified 24 Amplicon Sequence Variants (ASVs) with relative abundances significantly different between the wild and captive beetles. Many of the ASVs overrepresented in captive beetle microbiomes belong to taxa linked to nitrogen-rich environments. This is one of the first studies comparing the effects of captivity on the microbiome of an endangered insect species. Our findings provide valuable information for future applications in the management of captive populations of H. comalensis.
