Key colonist pools and habitat filters mediate the composition of fiddler crab–associated bacterial communities

Abstract: The diversity and composition of local communities depends strongly on the pool of species that have been able to colonize that community from elsewhere. Typically this is thought to depend on a larger regional species pool that is subject to local environmental constraints that act as "filters." Often, however, colonists arrive from multiple sources that differ in habitat conditions and have therefore already experienced distinct "prefiltering." Consequently, it is the interaction of species from these distin… Show more

“…A white biofilm exists on the carapace surface of wild X. testudinatus (as we observed in Figure 1E), which may be a layer of the bacterial mat (Wang et al, 2014). Indeed, a previous study showed that the microbial community on the carapace of fiddler crabs (Uca panacea) was closely related to the community in the surrounding sediments (Cuellar-Gempeler and Leibold, 2019). Furthermore, the microbial epibiotic communities' significance on the carapaces of deep-sea galatheid squat lobsters (Munidopsis alvisca) was interpreted as a mutualistic host-microbe relationship for sulfide detoxification (Leinberger et al, 2022).…”

“…This analysis was carried out after removing lichenized OTUs and we also performed this test on all fungal orders comprising more than 1% of all sequences. All chemical parameters (pH, N, TPC) were included in the model without interaction components (Cuellar‐Gempeler & Leibold, ). The effect of predictor variables was quantified using likelihood‐ratio tests (ANOVA, pit trap resampling, 999 bootstraps) and Bonferroni correction.…”

“…The environment can act as a source for holobiont microbiota that in turn are shaped by strong selective forces driven by the host biology and behaviours. For example, fiddler crabs carapace and gut 66 are colonized by different pools of microbial colonists that are taken up from the environment, but the burrowing and filter feeding behaviors of the crabs finely select such colonists from the sediment after strongly reconditioning its geochemical properties 67 .…”
