“…In other words, the creation of a more heterogeneous and connected landscape may have affected the interaction network of pre‐existing lagoons. This is consistent with previous studies linking more interconnected networks to higher environmental heterogeneity (Moreira et al 2015) and improved biodiversity in wetland complexes or pond networks after the creation of new water bodies (Petranka et al 2007; Sebastián‐González & Green 2014; Minot et al 2021). It also aligns with metacommunity studies showing that landscape connectivity can play a major role in shaping local communities by modifying dispersal dynamics (Thompson et al 2017; Chase et al 2020).…”

Ecological recovery following restoration is typically evaluated using metrics based on species diversity and composition. However, increasing evidence suggests the success of long‐term ecological recovery increases when more complex attributes such as biotic interaction networks are targeted. In created lagoons, the influence of nearby habitats can generate early similarities in the community structure, but communities often diverge from surrounding water bodies at later successional stages. These changes have been attributed to the effect of biotic interactions, but few studies have tested this assumption. Here, we analyze the zooplankton community recovery after the creation of new lagoons in a Mediterranean coastal wetland using beta diversity approaches and mixed graphical models to infer interaction networks from abundance data. Increasing differences in the community structure between new and old lagoons were detected the second year after their creation. The overall interaction network was more complex in new than in old lagoons. Interestingly, the network structure in old lagoons increased its complexity during the third and fourth years after restoration. The creation of new lagoons with overall milder environmental conditions contributed to a greater differentiation of the zooplankton community structure between new and old lagoons. Moreover, our results suggest that the creation of a heterogeneous and more connected landscape can increase the interaction network in newly created and pre‐existing habitats, even if environmental conditions remain unchanged. We show how the inclusion of interaction networks for the monitoring of ecosystem recovery reflects unique facets of community complexity, otherwise overlooked when targeting diversity metrics alone.

“…This difference in results may be due to the fact that the populations of I. elegans can reach very high densities at some sites, which increases the observed intra-population variation and limits genetic drifts. For instance, in a survey of 20 ponds in Normandy, the larval density of I. elegans, was about 6 times higher than that of A. imperator [100]. The small populations of A. imperator may, therefore, be more prone to genetic differentiation in case of reduced gene flows [7].…”

Anthropogenic activities cause loss and fragmentation of natural habitats and have strong effects on population maintenance by increasing their isolation. Pond ecosystems are scattered waterbodies that can interact as a network connected by dispersal events of freshwater organisms. Identifying local genetic differentiations and understanding how gene flow occurs across these networks is essential to prevent risks associated with environmental perturbations. This study aimed to investigate genetic diversity and structure of Anax imperator Leach, 1815 populations at both regional and European scales using seven microsatellites markers. Seven populations of A. imperator were sampled in northwestern France and four populations were sampled in Italy (Sicily), Czech Republic, Switzerland and United Kingdom (U.K.). French populations presented a low genetic differentiation indicating a high gene flow and confirming dispersal events of this species between ponds at regional scale. No pattern of isolation by distance was found at the European scale. The populations presented a low genetic differentiation and no pattern of isolation by distance, suggesting historical or current movements of individuals. Only the U.K. population presented a significant genetic differentiation from other European populations, suggesting that the English Channel might act as a barrier to gene flow for A. imperator. However, Bayesian analysis showed that some dispersal events could occur between the U.K. and France (Normandy), probably facilitated by prevailing winds.

“…In recent years, the potential for individual manmade ponds in urban environments to act as habitat to a variety of taxa has been proven (Le Viol et al 2012 ; Hassall 2014 ; Meland et al 2020 ; Perron and Pick 2020a ). Additionally, there is some evidence that stormwater ponds have the potential to facilitate connectivity among areas with disrupted ecosystems such as agricultural fields, highways, and cities (Minot et al 2021 ; Clevenot et al 2022 ; Šigutová et al 2022 ; Birch et al 2023 ; Liao et al 2022 ). Connectivity matters for various aquatic taxa within cities, such as diving beetles (Liao et al 2022 ), and invertebrates (Hyseni et al 2021 ).…”

“…Connectivity matters for various aquatic taxa within cities, such as diving beetles (Liao et al 2022 ), and invertebrates (Hyseni et al 2021 ). However, it is still not clear how connectivity of urban stormwater ponds is influencing adult odonates, a key group for aquatic ecosystem health that are active dispersers (but see Minot et al 2021 for the influence of pond connectivity on odonate nymphs). To address this gap, we tested how connectivity of the landscape surrounding urban ponds influences adult Odonata abundance, diversity, and species composition.…”

Context The successful dispersal of an animal depends, partly, on landscape connectivity. Urbanization poses risks to dispersal activities by increasing hostile land cover types. Objectives We investigated how connectivity of urban ponds impacted Odonata communities (dragonflies and damselflies), an order of semi-aquatic insects that actively disperse. Methods We sampled 41 constructed stormwater ponds and 8 natural ponds in a metropolitan area. The effect of connectivity and the quantity of available adjacent habitats was tested at different scales for dragonflies (900 m) and damselflies (300 m), determined by a literature analysis, to account for differences in suborder dispersal capabilities. Results Lower levels of connectivity and fewer nearest neighbours negatively impacted abundance, species richness, and composition of dragonflies (p values < 0.01, R2 = 0.18–0.70). Adult dragonfly abundance had a stronger positive relationship with connectivity than species richness. In particular, the abundance of adult dragonfly Leucorrhinia frigida, found almost exclusively at natural ponds, had a positive relationship with connectivity. Connectivity and the number of nearest neighbours had no significant impact on damselflies apart from a slight negative relationship between connectivity and species richness (p value = 0.02, R2 = 0.11). Natural ponds had significantly higher levels of connectivity when compared to stormwater ponds. Conclusions Our results suggest that dragonflies are positively affected by increased connectivity in an urban landscape, with no benefit of connectivity to damselflies at the scale measured. We recommend intentional planning of urban stormwater pond networks, where individual ponds can act as stepping stones, incorporated with strategic inclusion of beneficial land cover types.
