“…Some evidence that resting eggs survive desiccation comes from sampling naturally dried sediments, which possess resting eggs that hatch when rehydrated (Battauz, de Paggi, & Paggi, ; Crispim & Watanabe, ; Stenert et al, ; Walsh, May, & Wallace, ). Other proof comes from wet sediments, which are dried before starting hatching experiments (Chittapun, Pholpunthin, & Segers, ; Ning & Nielsen, ; Van Damme & Dumont, ).…”

Many zooplankton organisms produce resting eggs before harsh environmental conditions. After aquatic systems are recovered, animals hatch from resting eggs and help re-establish active communities. However, although the ability of resting eggs to survive desiccation is largely known, it is unclear to what extent the duration of desiccation affects the viability and hatching patterns of resting eggs. In this study, we assessed the viability of resting egg banks in naturally wet and dry sediments through ex-situ hatching experiments. In addition, we simulated dry out episodes of different durations (2 and 8 months) in wet sediments originating from temporary systems. We observed hatchlings of rotifers, cladocerans, copepods, ostracods, and anostracans in wet and dry sediments. Drying the sediments for different durations did not change the species richness and composition of hatchlings, possibly because temporary systems select for species and genotypes that are more prone to producing resting eggs, which survive desiccation. However, some species were stimulated to hatch after desiccation, suggesting that desiccation might help break the dormancy of resting eggs from temporary systems. Desiccation intervals up to 8 months likely do not affect the viability of resting eggs from temporary systems. Since many lakes are about to experience unpredictable droughts owing to human activities and ongoing global changes, the ability of resting eggs to tolerate desiccation will play a key role in zooplankton community recovery.

Droughts are commonly observed in arid and semi-arid regions and in areas with strong seasonality in precipitation. Overall, shallow lakes and ponds and small aquatic systems, such as rock pools, are more prone to drought episodes. Moreover, the damming and regulation of rivers, water diverted from rivers and lakes, and ongoing changes in precipitation and temperature patterns may also reduce water availability, SUPPORTING INFORMATION Additional supporting information may be found online in the Supporting Information section at the end of the article.

“…It was possible to see that there was a difference in species permanence in the hydroperiod, since B. iheringi was predominant at the beginning and only afterward E. pampa predominated. Many authors describe the importance of this variation in the permanence of the species for equilibrium in the reestablishment of communities of intermittent environments (BRENDONCK, 1996;WANG et al, 2012;PINCEEL et al, 2017;STENERT et al, 2017). This variation can be affected by competition for food or space for reproduction.…”

“…This may suggest that hydration time is more important than temperature for B. iheringi hatching, because hatching occurred in all the hydroperiods of the year, regardless of the duration of the water (short or long period), or the temperature that was recorded. The duration of the water was also an important factor in the reestablishment of other crustaceans, such as Cladocera (FLORENCIO et al, 2015;STENERT et al, 2017) and Copepoda (FLORENCIO et al, 2015) For E. pampa, the response was the reverse as that recorded for the first species, as it seems that the temperature is as important as the duration of the water since hatching only occurred in the long winter hydroperiod. The temperature increase caused hatching on the fourth day of the hydroperiod for this species, indicating the importance of this factor for hatching of E. pampa.…”

“…Precipitation is reduced in other seasons, but occasionally occurs, and water remains for a few days. The difference in the duration of hydroperiods may affect the frequency and intensity of species hatching throughout the year, since hatching stimuli may also vary (STENERT et al, 2017). The long photoperiod stimuli and high temperatures that occur in the warmer months are related to the volume of precipitation, which can result in long periods without water in the summer months (ALVARES et al, 2014).…”

“…Variables related to seasonal patterns in temperature were chosen because of their general association with the spatial distribution of zooplankton species (Viana et al, 2016). In addition, annual and seasonal regimes of precipitation and temperature are of high importance to the hydrology of seasonal ponds, with important effects on the composition of resting stages in seasonal ponds (Stenert et al, 2017). We used the standardized values of each variable in our procedures.…”

Most zooplankton species inhabiting seasonal ponds produce dormant stages to overcome the dry seasons. Zooplankton specimens emerging from the sediment contribute to the ecological dynamics of these ecosystems, because they constitute important energy sources for higher trophic levels in aquatic food webs. In contrast to snapshot studies of the active communities, studying the ecological correlates of the distribution of the egg bank can help identify the potential drivers of zooplankton composition. We tested the association of local (habitat structure and water chemistry), climatic and spatial predictors with the alpha and beta diversity of zooplankton hatchling communities in subtropical seasonal ponds. Incubation experiments were conducted with sediment samples from 11 ponds distributed along an approximately 500‐km latitudinal gradient in southern Brazil. We assessed the patterns for the total community, Cladocera only and Rotifera only. The alpha diversity of the total community and Cladocera were primarily related to substrate heterogeneity. Annual rainfall and substrate heterogeneity jointly influenced the beta diversity of the total community. Annual rainfall solely influenced the beta diversity of Cladocera, while substrate heterogeneity influenced the overall beta diversity of Rotifera. Overall, the distinct relationships of the total hatchling community and Cladocera and Rotifera with the explanatory datasets suggest differing sensitivities of the zooplankton groups to impacts in habitat structure and climatic conditions in subtropical seasonal ponds.
