Traditionally metacommunity studies have quantified the relative importance of dispersal and environmental processes on observed β-diversity. Separating β-diversity into its replacement and nestedness components and linking such patterns to metacommunity drivers can provide richer insights into biodiversity organization across spatial scales. It is often very difficult to measure actual dispersal rates in the field and to define the boundaries of natural metacommunities. To overcome those limitations, we revisited an experimental metacommunity dataset to test the independent and interacting effects of environmental heterogeneity and dispersal on each component of β-diversity. We show that the balance between the replacement and nestedness components of β-diversity resulting from eutrophication changes completely depending on dispersal rates. Nutrient enrichment negatively affected local zooplankton diversity and generated a pattern of β-diversity derived from nestedness in unconnected, environmentally heterogeneous landscapes. Increasing dispersal erased the pattern of nestedness, whereas the replacement component gained importance. In environmentally homogeneous metacommunities, dispersal limitation created community dissimilarity via species replacement whereas the nestedness component remained low and unchanged across dispersal levels. Our study provides novel insights into how environmental heterogeneity and dispersal interact and shape metacommunity structure.

What can observational data reveal about metacommunity processes?

A key challenge for community ecology is to understand to what extent observational data can be used to infer the underlying community assembly processes. As different processes can lead to similar or even identical patterns, statistical analyses of nonmanipulative observational data never yield undisputable causal inference on the underlying processes. Still, most empirical studies in community ecology are based on observational data, and hence understanding under which circumstances such data can shed light on assembly processes is a central concern for community ecologists. We simulated a spatial agent-based model that generates variation in metacommunity dynamics across multiple axes, including the four classic metacommunity paradigms as special cases. We further simulated a virtual ecologist who analysed snapshot data sampled from the simulations using eighteen output metrics derived from beta-diversity and habitat variation indices, variation partitioning and joint species distribution modelling. Our results indicated two main axes of variation in the output metrics. The first axis of variation described whether the landscape has patchy or continuous variation, and thus was essentially independent of the properties of the species community. The second axis of variation related to the level of predictability of the metacommunity. The most predictable communities were niche-based metacommunities inhabiting static landscapes with marked environmental heterogeneity, such as metacommunities following the species sorting paradigm or the mass effects paradigm. The most unpredictable communities were neutral-based metacommunities inhabiting dynamics landscapes with little spatial heterogeneity, such as metacommunities following the neutral or patch sorting paradigms. The output metrics from joint species distribution modelling yielded generally the highest resolution to disentangle among the simulated scenarios. Yet, the different types of statistical approaches utilized in this study carried complementary information, and thus our results suggest that the most comprehensive evaluation of metacommunity structure can be obtained by combining them.

Indo-West Pacific coral reef fishes form speciose ecological communities. A biogeographically meaningful interpretation of diversity patterns in this region requires accurate inventories of species. Previous studies have suggested that biogeographic scenarios for Indo-West Pacific coral reef fishes are compromised by an unacknowledged yet substantial amount of cryptic diversity. DNA barcoding, the use of a mitochondrial gene as an internal species tag for species identification, has opened new perspectives on global biodiversity. The present study, based on the largest DNA barcode reference library produced to date for Indo-West Pacific coral reef fishes, sheds new light on the extent of cryptic diversity and its evolutionary origin. We analyzed 3174 DNA barcodes for 805 species of coral reef fishes sampled at 3 different locations across the IndoWest Pacific (including 538 new DNA barcodes for 270 species sampled from New Caledonia). Among the 183 species with Indo-West Pacific distribution and multiple specimens analyzed, 78 (42.6%) were represented by 2 or more monophyletic lineages alternatively sorted between the sampling sites in the Indian and Pacific oceans and another 73 (40%) showed evidence of phylogeographic structure. Spatial analyses pointed to a detectable impact of geographic isolation on the emergence of cryptic diversity. The significant correlation of several life history traits to the maximum intraspecific genetic distances suggests that genetic divergence among geographically isolated cryptic lineages accumulated though mutation and genetic drift.
