“…However, microbiotas are strikingly diverse across animal groups in terms of the number of symbiont species (Engel and Moran, 2013;Colston and Jackson, 2016). For instance, vertebrates typically harbor more symbionts than invertebrates, presumably due to underlying differences in their morphology, physiology, and immunity (McFall-Ngai, 2007;Engel and Moran, 2013;Colston and Jackson, 2016;Woodhams et al, 2020). Conversely, animals feeding on complex diets typically harbor more symbionts than those feeding on simple diets, presumably because they have an increased diet-related uptake of environmental microbes or need to maintain a higher symbiont diversity to ensure the digestion of their diet (Ley et al, 2008a;Engel and Moran, 2013;Reese and Dunn, 2018).…”

Symbioses between animals and microbes are ubiquitous, and often have drastic fitness effects on both parties. A rapidly growing body of research now shows that many of these effects are driven by social interactions among the symbionts. For instance, microbes frequently cooperate by producing shareable "public goods" that can mediate both virulence and host-beneficial functions. Conversely, hosts often exert control over symbionts by targeting their social interactions. Despite this pivotal role, we have only started to uncover the full diversity of microbial interactions, and many of the factors that shape variation in their effects on host function and evolution across different symbioses remain elusive. Here, we (i) review the known diversity of microbial interactions across different symbioses, and (ii) argue that variation in their nature and impact is often determined by differences in symbiont diversity. In particular, we first give a primer on the social lives of microbes, and then discuss how intraspecific and interspecific interactions among microbial symbionts affect -and are affected by -their host. Subsequently, we move to the evolution of symbiosis, and discuss the role of microbial interactions in symbioses that feature only few versus many different symbiont species. We show that symbiont-rich symbioses are shaped by strong interspecific competition, which selects against many host-beneficial forms of microbial cooperation, and thereby limits the scope for the evolution of strong host-symbiont dependencies. Conversely, symbioses involving only few symbiont species are often characterized by forms of microbial cooperation that mediate host-beneficial services, a situation that increases the scope for the evolution of host-symbiont dependencies. Overall, we infer that the explicit consideration of social dynamics within symbiont communities of varying complexity is crucial to advance our understanding of how microbes shape animal function and evolution.

“…Gammaproteobacteria is a highly diverse clade common in the marine environment and many marine hosts [40,51], so in this case the processes driving a co-phylogenetic pattern with Cerithideopsis are unclear. In general, it is surprising that significant co-phylogenetic divergence between geminate hosts and their microbiomes was only evident in shell-surface biofilms of Cerithideopsis , as these communities are expected to be more influenced by the external environment than the biology of host [16,52].…”

The rise of the Isthmus of Panama ~3.5 mya separated populations of many marine organisms, which then diverged into new geminate sister species currently living in the Eastern Pacific Ocean and Caribbean Sea. However, we know very little about how such evolutionary divergences of host species have shaped their microbiomes. Here, we compared the microbiomes of whole-body and shell-surface samples of geminate species of marine gastropods in the genera Cerithium and Cerithideopsis to those of congeneric outgroups. Our results show that the effects of the Isthmus on microbiome composition varied among host genera and between sample types within the same hosts. In the whole-body samples, microbiome compositions of geminate species pairs in the focal genera tended to be similar, likely due to host filtering, although the strength of this relationship varied among the two groups and across similarity metrics. Shell-surface communities showed contrasting patterns, with co-divergence between the host taxa and a small number of microbial clades evident in Cerithideopsis, but not Cerithium. These results suggest that (i) the rise of the Isthmus of Panama affected microbiomes of geminate hosts in a complex and clade-specific manner and (ii) host-associated microbial taxa respond differently to vicariance events than the hosts themselves.

“…We sampled both the gill tissues and shell-surface biofilms of M. californianus to compare latitudinal diversity patterns between micro-environments with different levels of exposure to ambient conditions, as the compositions of internal (gut) and external (skin, leaf, etc.) microbial communities have been shown to respond differently to host-derived and environmental factors (Woodhams et al, 2020). We hypothesized that the gill and shell-surface microbiomes of this host, as well as individual microbial clades, would show a decrease in both alpha and gamma diversities with increasing latitude, as has been seen in animals and free-living microbes (e.g.…”

Aim The latitudinal diversity gradient (LDG) is one of the most pervasive large‐scale trends in biodiversity. However, whether microbial taxa also conform to this pattern remains poorly known. This study uses the gill and shell‐surface microbiomes of the marine bivalve Mytilus californianus to test whether the diversity of host‐associated microbial communities declines with increasing latitude, as predicted by the LDG. Location Northeastern Pacific coast, ranging from Sitka, AK to La Jolla, CA, USA (spanning 24.12 degrees of latitude). Taxon Bacteria and Archaea associated with M. californianus gills and shell‐surfaces. Methods We amplified and sequenced the 16S rRNA gene from M. californianus gill and shell‐surface samples. We used linear and quadratic regressions, accounting for spatial autocorrelation when needed, of average alpha and gamma diversities of the whole microbiome, as well as individual microbial clades, to determine whether these taxa conformed to the traditional LDG. We also used permutational multivariate analysis of variance to determine the level of compositional differentiation among sampling sites. Results Gill and shell‐surface microbiota show differing latitudinal diversity patterns, with both micro‐environments exhibiting high levels of compositional differentiation along latitude. Individual microbial clades within each micro‐environment also show different latitudinal trends, most likely due to differing ecologies and life histories. Main conclusions Mytilus californianus‐associated microbial taxa show a flat, hump‐shaped or contrarian LDG, suggesting that a steep decline in diversity with increasing latitude may not be a universal pattern across different domains of life.

Abstract: Following publication of the original paper [1], it was reported that an error in the processing of Fig. 8 occurred. In the online HTML version of the article, Fig. 8 was presented as a duplication of Fig. 7. The original article [1] has been corrected.
