“…In the last decade, various studies carried out on zooplankton of temporary ponds (KING et al, 1996;SERRANO and TOJA, 1998;FAHD et al, 2000;MURA and BRECCIAROLI, 2003) have evidenced that these waterbodies could support an high number of species. However, as reported above, high altitude ponds usually have food chains of low complexity and are thought to support low diversity (HANSSON and TRANVICK, 1996).…”

“…Kellicottia longispina (BRAIONI and GELMINI, 1983) (Table 3). Species richness has been usually related to pond surface areas and volumes (e.g., DODSON, 1992;DODSON et al, 2000;SHURIN et al, 2000;MURA and BRECCIAROLI, 2003). Nonetheless, such a relationship was not observed in the studied pools, probably due to the small size variation among sites and also because an increase in pond surface area does not necessarily correspond to a greater variety of microhabitats.…”

“…Communities of temporary waterbodies have recently been analysed in a number of papers WYNGAARD et al, 1991;CORTI et al, 1997;MURA and BRECCIAROLI, 2003). However, most of these studies have considered temporary habitat located at low altitudes and/or characterised by a mediterranean climate.…”

In 2001 nine temporary pools of the northern Apennines (Italy) were visited on 13 occasions during the ice-free season (May to October). The aims of this research were to define the relationships between hydroperiod and other environmental variables and the zooplankton. In total, 49 zooplankton taxa were identified: 36 rotifers, 5 cladocerans, 6 copepods and 2 anostracans. Our results indicate that hydroperiod is a major determinant affecting zooplankton species richness. The highest number of taxa was found in the pond having the longest duration. Distinctive species assemblages were observed in different habitat types: pools with the shortest hydroperiod were characterised by organisms with brief life cycles (e.g. rotifers) and/or typical of temporary habitat (e.g. anostracans). Of the physical and chemical characteristics, pH and chlorophyll-a appeared to have the largest influence on zooplankton distribution in the studied pools.

“…Zooplankton communities play an important ecological role in shallow temporary lakes because these organisms occupy different niches in aquatic food webs, and they contribute to element recycling and energy transfers (El-Shabrawy et al 2015). Thus, changes in zooplankton community composition can alter characteristics of a lake, such as water transparency, phytoplankton composition, and chlorophyll-a concentration (Jenkins et al 2003; Echaniz, 2010).Several ecological aspects of temporary lakes have been studied in Australia (Williams et al 1998; Bayly, 2001;Roshier et al 2001), North America (Smith et al 2003Wallace et al 2005), and Europe (Mura & Brecciaroli, 2003;Frisch et al 2006).

Central Argentina has numerous saline lakes sustained by groundwater sources and rainfall. These lakes are temporary and experience significant changes in water level and salinity, depending on wet and dry climate cycles. This study aims to investigate the scarcely known dynamics of environmental and zooplankton parameters during the drying phase of one of these lakes. Monthly samples were taken from December 2 012 to July 2 013 in the Ojo de Agua Uriburu lake, previous to its drying. At the beginning of the study, the lake's depth was 0.7 m and its salinity was 16.65 g L −1 , later, in July, its depth decreased to 0.06 m and its salinity increased to 92.9 g L −1 . Zooplankton species richness was low (three crustaceans and three rotifers), with Boeckella poopoensis and Moina eugeniae dominating in the system. Maximum density and biomass were attained by the two dominant species in April (318.5 i nd L −1 and 3 029.1 µg L −1 dry weight; and 242.4 i nd L −1 and 1 530.4 µg L −1 dry weight, for B. poopoensis and M. eugeniae, respectively), and no correlation was found between these parameters and salinity. Maximum average body lengths for both species were observed in the last months of sampling (M. eugeniae: 1 020 ± 84.2 µm and B. poopoensis: 1 348.8 ± 89.0 µm). At this point of the study, neither juvenile nor larval stages were found. The increase in average body size is, arguably, the result of increased salinity in the system through a negative effect on reproduction. Because this lake reached hypersalinity, its ecological dynamics are unique among those of other temporary, saline lakes that dried in central Argentina. Similar studies on other temporary ecosystems are needed to increase the information on these little known ecological aspects.Keywords: temporary lake; saline lake; hydroperiod; zooplankton; Boeckella poopoensis; Moina eugeniae. IntroductionTemporary lakes contain water during periods as short as a few months and up to several years (Schwartz & Jenkins, 2000). These lakes are globally distributed, and their sizes range from a few square meters to hundreds of (Williams, 1987;Schwartz & Jenkins, 2000). Many of these ecosystems are disappearing because of anthropic activity, including their transformation into agricultural fields (Belk, 1998;Williams, 2002;Jenkins et al. 2003; Eitam et al. 2004). The transformation and destruction of these ecosystems leads to species loss, thus significantly affecting local biodiversity (Waterkeyn et al. 2008).Most water bodies in La Pampa province, a central semiarid region of Argentina, are shallow (maximum depth < 3 m), temporary lakes. These lakes occur in arheic basins, where surface runoff flows unpredictably due to lack of drainage patterns (Mann, 2002; World Meteorological Organization, 2012;Meybeck et al. 2013), and they are formed by phreatic input and, to a lesser extent, by rainfall (Dornes et al. 2016).Most of the Pampean temporary lakes are saline; with ions such as Na + and Cl − predominating in their composition (Echaniz, 2010), and concentr...

Quantifying the Hydroregime of a Temporary Pool Habitat: A Modelling Approach for Ephemeral Rock Pools in SE Botswana

et al. 2007

Ecological and evolutionary processes in temporary rock pools operate within constraints imposed by their hydrologic regimes. These shallow pools flood when seasonal rains accumulate on impermeable substrates. Despite the ecological importance of hydrologic conditions for these ecosystems, we typically lack tools and empirical data required to understand the implications of hydrologic variability and climate change for biotic populations and communities in these habitats. In this study, we developed a hydrologic model to simulate rock pool hydrologic regimes based on rainfall, evapotranspiration, and basin geometry. The model was used to investigate long-term patterns of seasonal and interannual variation in hydroregime. In addition, hydrologic conditions associated with potential climate change scenarios were simulated and evaluated with respect to the biological requirements of the anostracan Branchipodopsis wolfi. The model's output for daily inundation matched with field observations with an overall accuracy of 85% and correctly estimated complete hydroperiods with an overall accuracy of 70%. Simulations indicate large variation in individual hydroperiods (76-115%) as well as in the number of hydroperiods per year (19-23%). Furthermore, this study suggests that climate change may significantly alter the rock pool hydroregime. These findings confirm the hydrologic sensitivity of these ephemeral habitats to precipitation patterns, and their potential sensitivity to future climate change. Modelling indicates that the suitability of average inundation conditions for B. wolfi deteriorates significantly under future climate predictions. High levels of spatial and temporal variation in hydrologic conditions are dominant features of these habitats and an essential consideration for understanding population and community-level ecological processes.
