“…Our results show an unexpectedly high neutral-based structuring during the seasons corresponding to infilling and maximum flooding, that eventually decreases during the dry season (the desiccation phase), in relation to the relative importance of environmental filtering for all groups (except Mollusca). The observation of relatively high neutral structure at the onset of the hydroperiod was previously observed by Castillo-Escrivà et al (2017c) in ostracods from temporary lakes, suggesting an initial hatching bloom of opportunistic species from the egg bank (Olmo et al, 2012) provoking more random associations that would later become structured by species filtering, i.e., niche-related processes. As previous studies suggest, seasonal floods produce spatial deconstruction, increasing connectivity and dispersal of many organisms, so as dilution effects and environmental homogenization (Thomaz et al, 2007;Rojo et al, 2016).…”

“…Mass and priority effects at small scales (Heino et al, 2015;Castillo-Escrivà et al, 2017b) and dispersal limitation at large (Soininen et al, 2011;Heino et al, 2015) or even small spatial scales (Castillo-Escrivà et al, 2017a) seem also to be important processes affecting pond metacommunity structure. Temporary ponds, as intermittent ecosystems, strongly depend on seasonal dynamics related to their hydroperiod, egg-bank hatching and colonization processes (Williams, 2005;Chase, 2007;Castillo-Escrivà et al, 2017c). Desiccation is a major evolutionary pressure in temporary water bodies, where habitat availability changes cyclically, sometimes unpredictably, and organisms are adapted to this desiccation by means of different life-cycle strategies: while some organisms resist drought in the sediment (resting eggs, anhydrobiosis, seeds, etc.…”

“…highlighted the influence of spatial scale on the inference of these processes when analyzing communities sampled once (e.g., Condit et al, 2002;Heino et al, 2017;Viana and Chase, 2019), or comparing the spatial effects between several temporal points of the same metacommunity (e.g., Langenheder et al, 2012;Fernandes et al, 2014;Castillo-Escrivà et al, 2017). Other studies have focused on the effects of temporal scales on temporal turnover, but at one spatial point (e.g., Korhonen et al, 2010;Tomašových and Kidwell, 2010).…”

“…Neither could we assess the role of environmental heterogeneity, because of the lack of objective measurement. We can only suggest that the single reported absence of a spatial structure in an ostracod metacommunity, determined in 10 lakes over a steep environmental gradient (Castillo-Escrivà et al, 2017b), might be the consequence of a very high environmental heterogeneity.…”
