Re-establishment of zooplankton communities in temporary ponds after autumn flooding: Does restoration age matter?

a b s t r a c tIn temporary ponds, reestablishment of zooplankton communities depends on recruitment from the egg bank, the arrival of dispersers from within the region, and on successful establishment of newly arrived species following interaction with local abiotic and biotic factors. When the ponds dry up, zooplankton species may survive as dormant eggs, and since not all eggs hatch in the next season, eggs will accumulate in the sediment over time, representing an archive of the pond's historical biodiversity.To study the effect of "restoration age" (the time since a water body was restored), we studied groups of ponds that were restored in different years (1998, 2003 and 2007). The restoration process involved extensive dredging of sediments which were used to bury the ponds in the 1960s. Our expectation was that the oldest ponds would have the richest zooplankton community, as they have been accumulating biodiversity over a longer time period. We took weekly quantitative samples of zooplankton during four consecutive weeks after flooding to compare taxon richness and zooplankton community composition between ponds of different restoration age during an early stage of zooplankton community re-establishment.Taxon richness was high and similar to regional levels in all the ponds under investigation, suggesting restoration success and unlimited dispersal. Although cumulative richness at the end of the period was not significantly different between ponds, we observed temporal changes within the study period and certain age-related trends in relation to differences in zooplankton composition. These results suggest a difference in the succession of zooplankton communities depending on restoration age (which could be due to historical or local factors) and that this effect becomes evident from the beginning of the pond hydroperiod.

“…Since the 1990s, several restoration projects have been undertaken to restore the coastal dune fields and to create new ponds in the silted old basins (more information can be found in Anto´n-Pardo andArmengol, 2010 andOrtells et al, 2012). However, the studied pond (39x20'24.38''N; 0x18'34.92''W) was not silted in that period and always maintained a water column more than 1 m deep at all times, but presented a high density of emergent vegetation and poor water quality (Soria and Alfonso, 1993). During summer 2003, the pond was restored by digging an adjacent basin, which was connected with the old one, making possible the arrival of zooplankton and fish from the old pond.…”

“…Although the samplings were performed by different people in each period, similar equipment and methods were used throughout the time. In the study conducted prior to the restoration (1987)(1988), a total of eight samples were taken bimonthly (Soria Garcı´a, 1988;Soria and Alfonso, 1993;Alfonso, 1996). In each sampling, conductivity, dissolved oxygen and pH were measured.…”

“…We hypothesise that this process modified several environmental variables in the water body, improving water quality (mainly a decrease in chlorophyll a concentration and an increase in dissolved oxygen), and thus, zooplankton community turned into a more diverse community, with the presence of indicator species of these variations. For this purpose, the current zooplankton community and the environmental features (from Autumn 2006 to Summer 2009) were compared with a set of data obtained from a study performed 15 years before restoration (from February 1987to January 1988Soria Garcı´a, 1988;Soria and Alfonso, 1993;Alfonso, 1996) and with data collected in 2004-2005, just after restoration.…”

-Restoration projects in wetlands are becoming increasingly frequent to recover or to create new aquatic ecosystems, after the significant impact and high degradation they have undergone. In the present study, we focused on the changes in the zooplankton community in a permanent peridunal pond where a restoration was carried out in order to increase its surface as a main objective. For this purpose, the community was compared before and after the restoration (15 years before, the year after and between 3 and 6 years later). Significant changes in environmental variables were observed after pond restoration: chlorophyll a concentration decreased and dissolved oxygen increased. Substantial modifications in the aquatic community were also observed, since species richness and diversity increased after restoration: a large number of new species appeared (84%, mainly cladocerans), from external or internal sources. In addition, zooplankton community structure and composition changed from a low specific richness community copepod-dominated in density (mostly nauplii) before restoration, to another one with higher richness and different composition co-dominated in density by rotifers and nauplii, but with greater abundance of cladoceran species. All this suggests an important change in the ecological functioning of the pond, mainly produced by improvement in habitat heterogeneity and water quality after restoration.
