“…The structure of the rotifer metacommunity in the ponds seems to be determined by environmental factors acting at the local scale rather than by spatial factors related to regional-scale processes such as dispersal, which is in line with previous studies conducted at comparable spatial scales ( Waterkeyn et al ., 2008 ; Antón-Pardo et al ., 2015 ). The explained variance analysis indicated that niche processes seem to prevail in structuring the rotifer assemblage in spring, with habitat filters selecting different rotifer genera in each pond.…”

Understanding the influence of environmental and spatial factors on the structure of aquatic communities remains a major challenge in community ecology. This study aims to identify main drivers of rotifer abundance and diversity in ponds embedded in an intensive agricultural landscape in Northeast Germany. We studied 42 ponds of glacial origin (kettle holes) covering a wide range of environmental parameters. The predominant factors structuring the rotifer metacommunity shifted from abiotic environmental filtering in spring to unstudied factors in autumn, while spatial factors remained less important. Fertilizer-driven salinization, internal nutrient recycling, primary productivity and sediment phosphorus release were the prevalent biogeochemical processes in the ponds. Both fertilizer-driven salinization and primary productivity negatively affected rotifer alpha diversity, and positively affected beta diversity. This impact was lower in forest ponds than in those surrounded by arable fields or grassland. However, rotifer diversity did not significantly differ among land-use categories. Our results indicate that the long-term impact of intensive agriculture in the region and the associated widespread eutrophication overrides the direct influence of land use on rotifer diversity but point to an indirect effect via fertilizer-driven salinization. Furthermore, this study highlights the role of ponds in enhancing regional biodiversity in agricultural landscapes.

“…In La Pletera salt marshes, there is a short distance between the new lagoons and the existing ones, facilitating the colonization of the new lagoons. Antón-Pardo et al (2016) mention that the short distance among the lagoons and the apparent absence of geographical barriers facilitate the occurrence of zooplankton dispersal vectors (e.g., waterbirds, wind or humans). Other studies performed on permanent and temporary lagoons showed a similar pattern to that found in the La Pletera salt marshes (Cottenie et al, 2003;Audet et al, 2013;Antón-Pardo et al, 2016).…”

“…Zooplankton assemblages respond rapidly to variations in environmental factors such as those caused by hydrological instability in Mediterranean coastal ecosystems (Quintana et al, 1998a(Quintana et al, , 1998bBrucet et al, 2005;Badosa et al, 2006;Olmo et al, 2016). However, other factors or processes such as dispersal ability or priority effects also affect the colonization dynamics and, consequently, the zooplankton composition of restored wetlands (Bilton et al, 2001;Cohen & Shurin, 2003;Ortells et al, 2012;Antón-Pardo et al, 2016). These assemblages are dominated by passive dispersers that are characterized by a high dispersal ability by wind or bird transport (but see Incagnone et al, 2015); thus, they rapidly colonize new water bodies (Louette & De Meester, 2005;Frisch et al, 2006;Olmo et al, 2012;Audet et al, 2013).…”

How do zooplankton respond to coastal wetland restoration? The case of newly created salt marsh lagoons in La Pletera (NE Catalonia)We analysed the changes in the zooplankton composition in several new and old lagoons in La Pletera, a confined Mediterranean coastal salt marsh located in the Baix Ter wetlands (NE Iberian Peninsula) that was subjected to a restoration project (Life Pletera). We sampled the zooplankton from three new lagoons immediately after their creation (1 and 2 months after), and we compared the zooplankton with those of three existing lagoons, two natural lagoons and one lagoon created fourteen years ago in a previous restoration project. The sampling included seven months before the first hydrological connection to the surface waters, when flooding during a sea storm connected the new lagoons with the existing lagoons for the first time, and seven months after. The results showed that the nutrient and organic matter concentrations were lower in the new lagoons than in the old lagoons, suggesting accumulation processes in these ecosystems, which were probably related to the long periods of confinement that typically follow flooding events in this type of lagoons. However, we did not find significant differences in the zooplankton community between the old and new lagoons. The seasonal variation in the zooplankton communities was strongly affected by the seasonal hydrological flooding -confinement pattern, which did not differ between the old and new lagoons. Calanoid copepods, mainly Eurytemora velox, dominated during winter, while the rotifer Brachionus plicatilis dominated in summer, coinciding with the highest degree of confinement. The environmental variables and the hydric connection explained 31 % of the zooplankton variability. The high connectivity of the system once it flooded aided dispersal, the hatching of the egg banks existing in the restored lagoons and the fast response of the zooplankton species to changes in the environmental conditions (although with some degree of delay) might explain the lack of significant differences between the zooplankton composition in the old and new lagoons.

“…Large fractions of unexplained community variation remain, however, suggesting an important role for the elements of chance or randomness (Jeffries 1989). Stochastic processes and priority effects are expected to be strong at the beginning of the hydroperiod due to egg-bank hatching, before abiotic and biotic sorting of species can effectively act as filters in structuring local communities (Antón-Pardo et al 2016;Castillo-Escrivà et al 2017c;Mahaut et al 2018). This results in increased unexplained variation, with model residuals accounting for a higher proportion in the tropical metacommunity, probably related to its higher species richness, but also because of lower limnological heterogeneity (Leibold and Chase 2018), as shown by the homogeneity test of multivariate dispersion.…”

The metacommunity concept provides a theoretical framework that aims at explaining organism distributions by a combination of environmental filtering, dispersal and drift. With the development of statistical tools to quantify and partially isolate the role of each of these processes, empirical metacommunity studies have multiplied worldwide. However, few works attempt a multi-taxon approach and even fewer compare two distant biogeographical regions using the same methodology. Under this framework, we tested the expectation that temperate (Mediterranean) pond metacommunities would be more influenced by environmental and spatial processes than tropical ones, because of stronger environmental gradients and higher isolation of waterbodies.We surveyed 30 tropical and 32 Mediterranean temporary ponds and obtained data on 49 environmental variables (including limnological, hydrogeomorphological, biotic, climatic, and landscape variables). We characterized the biological communities of Bacteria and Archaea (from the water column and the sediment), phytoplankton, zooplankton, benthic invertebrates, amphibians and birds, and estimated the relative role of space and environment on metacommunity organization for each group and region, by means of variation partitioning using Generalized Additive Models (GAMs).The residual (unexplained) variation was larger in tropical pond metacommunities, suggesting a higher role for stochastic processes and/or effects of unmeasured processes such as biotic interactions in the tropics. Environmental filtering was important in both tropical and Mediterranean ponds, but markedly stronger in the latter, probably related to higher environmental heterogeneity. The variability between taxonomic groups in spatial and environmental contributions was very wide, and only some similarities between geographic settings were observed for the environmental effects of passively dispersing organisms, with rotifers and diatoms being among the most and least affected by the abiotic environment, respectively, in both areas. Overall, these results provide support, in a wide variety of aquatic organisms, for the classical view of stronger abiotic niche constraints in temperate areas compared to the tropics.
