“…These authors showed that spatial factors explained most part of the community structure of some taxa in ponds (e.g. anurans, submerged macrophytes and zooplankton; Declerck et al 2011;De Bie et al 2012;Trindade et al 2018;Bertuzzi et al 2019;Knauth et al 2019). However, the relative importance of spatial and environmental factors may vary according to the focal organism (Soininen 2014;Heino et al 2015), and insects can be a remarkable exception to this expected pattern.…”

“…In intermittent ponds, it is implied that dispersal-related processes dominate in the early wet phase, and environmental ones, in the mid-and late-wet phases. As our design matched the last phase (Bertuzzi et al 2019;Knauth et al 2019), we covered the phase that was most likely structured by environmental (species sorting) processes.…”

“…Insect collection was carried out in the early spring of 2015 (from September to October; austral season), during the wet phase of the ponds (Bertuzzi et al 2019;Knauth et al 2019). This is also the season that is known to match the peak in the abundance and richness of many aquatic invertebrate taxa in the region (Lima et al 2013).…”

Metacommunity organisation in temporary ponds is assembled by spatiotemporally varying processes that are also contingent on the species' dispersal ability and scale of observation. Aquatic insects are useful models to study the relative contribution of environmental and spatial factors to community assembly in view of the differing dispersal ability existing in the species from this group. We assessed the metacommunity organisation of aquatic insects and subsets of strong-and weak-flying insects in relation to environmental (habitat structure; water chemistry; climate) and spatial factors in temporary ponds ranging along a latitudinal gradient in southern Brazil. Local and climate environmental factors (water chemistry and temperature) along with fine-scale spatial factors were the main drivers of the total insect community, although their relative importance shifted between subsets of weak-and strong-flying insects. The composition of strong-flying insects was structured by climate and fine-scale spatial factors, while weak-flying insects, by local (water chemistry) and spatially structured climate. This suggests that strong-flying insects showed stronger signatures of mass effects at finer scales, while weak-flying insects were more strongly affected by species sorting coupled to local environmental factors and regional climate. In summary, our results indicate that the relative importance of assembly processes for metacommunity organisation of aquatic insects in temporary ponds is contingent on dispersal ability.

“…Spider collection occurred in the austral spring of 2015 (from September to November). This period of the year corresponds to the mid‐to‐late wet phase of the wetlands in the study area, which eventually dry up between late spring and summer (Bertuzzi et al ., 2019; Knauth et al ., ). This season matches the peak in richness and abundance of many adult spider species in southern Brazil (Baldissera et al ., ; Podgaiski et al ., ), including temporary flooded habitats (Rodrigues et al ., , ).…”

1. The composition of local assemblages is assembled by an interplay of species sorting, mass effects and dispersal limitation processes. The contributions of assembly processes to metacommunity structure can change with ecosystem type and specificities of the study area. Spider composition is influenced by environmental features such as habitat structure and climate, and also by spatial distances between patches. However, little is known about the roles of assembly processes in spider metacommunity structure in wetlands.2. The beta diversity patterns of spider assemblages were assessed in 24 temporary wetlands distributed along a latitudinal gradient in southern Brazil. The study also assessed the individual correspondence of beta diversity (and its turnover and richness components) with dissimilarities in habitat structure and climate, as well as with geographic distances, using Mantel and partial Mantel correlation tests and multivariate correlograms.3. Turnover was the most important component of spider beta diversity. Mantel tests detected significant correlations of spider beta diversity with habitat structure. Partial Mantel tests detected significant relationships only between spider beta diversity (and the richness component) and geographic distances. Additionally, spider composition was more similar than chance on smaller scales. 4. These results evidenced a complex interplay of assembly processes explaining spider metacommunity structure in temporary wetlands. Although species-sorting processes associated with habitat structure were important in structuring local spider composition, mass effects and dispersal limitation across climatic zones played an important role on a broader scale.
