“…It has been postulated that drought acts as a strong selective pressure filtering species out and resulting in more similar, niche-assembled communities (Chase, 2007). However, we found short hydroperiod ponds less similar in species composition, as observed in another study of urban ponds drained of water during winter (Pinel-Alloul and Mimouni, 2013;Mimouni et al, 2015). One possible explanation may rely in the environmentally different short-hydroperiod ponds, where its shortlived inhabitants are more selected on the basis of conditions in the water column rather than on drought itself.…”

“…Several case studies, conducted in different cities and with different taxonomic groups, report a relationship between pond surface area and freshwater biodiversity (see details in Appendix S1). The relationship tends to be positive for microcrustaceans (Cladocera; Pinel-Alloul and Mimouni 2013, Mimouni et al 2015, macroinvertebrates (Hill et al 2015), specifically aquatic insects (Blicharska et al 2016), dragonflies (Jeanmougin et al 2014), amphibians (Parris 2006), and insectivorous bats (Straka et al 2016).…”

Review: Toward management of urban ponds for freshwater biodiversity

Many cities around the world are expanding and this trend in urbanization is expected to sharply increase over coming decades. At the same time, the integration of green and blue spaces is widely promoted in urban development, potentially offering numerous benefits for biodiversity. This is particularly relevant for urban waterbodies, a type of ecosystem present in most cities. However, site managers often lack the knowledge base to promote biodiversity in these waterbodies, which are generally created to provide other ecosystem services. To address this, our review presents guidelines for promoting biodiversity in urban ponds. We found a total of 516 publications indexed in ISI Web of Sciences related to this topic, of which 279 were retained for the purposes of our review. The biodiversity of urban ponds, measured by species richness, appears to be generally lower than in rural ponds; however, urban ponds often support threatened species. Furthermore, if well managed, urban ponds have the potential to support a much greater biodiversity than they currently do. Indeed, this review shows that a range of urban factors can impair or promote pond biodiversity, including many that can easily be controlled by site managers. Local factors include design (surface area, pond depth, banks and margins, shade, shoreline irregularity), water quality (conductivity, nutrients, heavy metals), and hydroperiod and biotic characteristics (stands of vegetation, fish, invasive species). Important regional factors include several indicators of urbanization (roads, buildings, density of population, impervious surfaces, car traffic), and the presence of other wetlands or green spaces in the surrounding landscape. We considered each of these factors and their potential impact on freshwater biodiversity. Taking into account the management measures listed in the publications reviewed, we have proposed a framework for the management of urban ponds, with guidelines to promote biodiversity and other ecosystem services, and to avoid ecosystem disservices or the creation of ecological traps. At the city scale, the biodiversity of a pondscape benefits from a high diversity of pond types, differing in their environmental characteristics and management.

“…Invertebrate and plankton communities have often been used to explore the multiple interlinked factors that drive diversity across different spatial scales, including connectivity, disturbance (droughts), and dispersal (Pedruski & Arnott, 2011;Vanschoenwinkel et al, 2011;Lopes et al, 2014); nutrient enrichment and predation (Beisner & Peres-Neto, 2009;Pinel-Alloul & Mimouni, 2013); and, more generally, stochastic versus deterministic assembly processes (Freestone & Inouye, 2015). Lakes and wetlands have been the classical settings for studies of invertebrate community structure (Brooks & Dodson, 1965;Wellborn et al, 1996).…”

Relationships between hydroperiod length, and seasonal and spatial patterns of beta-diversity of the microcrustacean assemblages in Mediterranean ponds

Temporary ponds are unpredictable habitats that exhibit inundation periods of variable duration (hydroperiods). We hypothesised that changes in microcrustacean assemblages, namely among ponds (spatial variation) and within ponds at a monthly scale (intra-annual variation), would differ according to hydroperiod length. We found that the microcrustacean assemblages of the study ponds demonstrated distinctive individual patterns that were dependent on monthly variation. During pond filling, species turnover was particularly high in short-hydroperiod ponds, probably due to the fast hatching of the initial pool of species, which seemed to determine subsequent species succession. Some of the long-hydroperiod ponds were able to hold water during the summer, which meant that they could harbour adult microcrustaceans in the early autumn, in contrast to the recently filled ponds; species turnover could thus increase at the onset of the inundation cycle. In the summer, species turnover decreased (while the contribution of nestedness to b-diversity increased) because only a few tolerant species were able to withstand the poor water quality found in drying ponds. We suggest that preserving the broader hydroperiod gradient, by protecting ponds with different environmental conditions within each hydroperiod category, would safeguard the ecological dynamics of the microcrustacean assemblages found in temporary ponds.
