Spatial differences become similar through time after wildfire disturbance: alpha and beta-diversity responses of Mediterranean temporary ponds faunal communities

Cunillera-Montcusí et al. (in press) Inland Waters.

We combined a network analysis approach with a mesocosms experiment to disentangle how large-scale and small-scale regional factors influence dispersal dynamics in a pond macroinvertebrate metacommunity. We set up several mesocosms around two source ponds with divergent locations within the network centrality–isolation gradient, at different distances and in different directions. The large scale, being central or isolated, determined abundance and richness across the hydroperiod, with greater values in central locations. However, this general pattern can be modulated by smaller regional factors and by intrinsic taxa dispersal ability.
