“…This approach calculates the distance of each group (here, pool identity) from the group centroid (all pools on one plateau), where higher dispersion represents higher heterogeneity. The significance of the observed values was tested using permutational ANOVA (at p = 0.05), and distances were visualized as principal coordinate analysis plots (Diniz et al 2021).…”

Determining drivers of community assembly is central to ecology, and patchily distributed temporary habitats offer an ideal system to study the roles of ecological and evolutionary processes in structuring communities over different spatial scales. We studied functionally diverse arthropod communities in 32 freshwater rock pools on 3 plateaus in the Western Ghats biodiversity hotspot, sampling them throughout their hydroperiod (2–7 months). Using the Hierarchical Modeling of Species Communities approach, we assessed (a) the influence of local (water chemistry, habitat complexity at the pool level) and regional (seasonality in temperature and precipitation at the plateau level) scale abiotic covariates in shaping species' occurrence, (b) the influence of species traits (dispersal/reproductive mode, body size, feeding guild) and phylogenetic relationships on species response to abiotic covariates, and (c) the strength of biotic filtering in the communities. Environmental filtering was the dominant driver of community structure, where the pool‐level covariates (mainly hydroperiod and water chemistry), explained greater variation (56.3%) in species occurrences rather than plateau‐level covariates, that is, climatic seasonality (33.7%). Spatial factors explained only 11% of the variation in species occurrences. The selected traits explained 22% variation in species' responses, with body size responding to the abiotic covariates at both spatial scales. Closely related taxa exhibited shared responses to the abiotic covariates. Only a few residual associations were observed, all among passive dispersers, indicating a low contribution of biotic filtering to community structure. Our results highlight the importance of habitat‐level factors and the key role of evolutionary processes in shaping diversity in this vulnerable landscape characterized by its seasonality.

“…By quantifying the influence of environmental filtering and evolutionary history in reef fish abundances we also demonstrated that local adaptation of the herbivore-invertivore complex to local primary productivity played an important role in the composition of these tropical reef fish assemblages. Functional traits and phylogeny are known to influence the way species respond to the environment (Hughes et al 2005, Emerson and Gillespie 2008, Ovaskainen and Abrego 2020, Diniz et al 2021) and how regional communities are assembled. Theory also predicts that in isolated sites nonnested taxonomic patterns predominate due to dissimilar species composition (Budd and Pandolfi 2010, Bender et al 2017, Maxwell et al 2022, possibly induced by endemism and reduced gene flow among populations.…”

“…Species are, therefore, assembled in communities according to evolutionary and ecological processes embedded in a spatio‐temporal context (Emerson and Gillespie 2008, Mouquet et al 2012). It is thus plausible to assume that species response to the environment, frequently called environmental filtering, has a joint structure that combines functional traits and phylogeny (Hughes et al 2005, Emerson and Gillespie 2008, Ovaskainen and Abrego 2020, Diniz et al 2021). As in other natural communities, evolutionary history and functional traits also drive reef fish community assembly (Bender et al 2013, Floeter et al 2017).…”

Complex phylogenetic origin and geographic isolation drive reef fishes response to environmental variability in oceanic islands of the southwestern Atlantic

Abiotic and biotic factors are known drivers that modulate community assembly from a regional species pool. Recent evidence has highlighted the intrinsic role of phylogenetic history on communities' response to the environment. Understanding its exact role poses a challenge because community assembly is embedded in a spatio‐temporal context where dispersal capabilities and biotic interactions may also determine species niches, especially in isolated oceanic islands. We unravelled how reef fish abundances from four oceanic islands in the southwestern Atlantic responded to environmental variability through seven years considering their phylogenetic history, functional traits and species co‐occurrence patterns. Species response to environmental variation was assessed through a multivariate hierarchical generalized linear mixed model that allows the inclusion of spatio‐temporal random effects, fitted with Bayesian inference. We found a strong phylogenetic signal (0.98) and a relatively low variance in abundance explained by functional traits, from around 30% in spring to 33% in summer, based on a posterior probability > 0.9. The most important environmental factor was surface chlorophyll‐a concentration, a proxy for primary productivity, explaining up to 23% of abundance variance. The global spatial and temporal effects on abundance were also low, with a maximum of 18% for sampling sites in spring. Our study offers a synthesis of the influence of complex phylogenetic history and geographical isolation on reef fish species niches in isolated oceanic islands, gaining new insights into how assembly processes have shaped these isolated communities.
