“…We found zooplankton communities from kettle holes to be mostly influenced by environmental factors (hydroperiod, pH, kettle hole size and surrounding field crops), with smaller but significant seasonal and spatial (pond location) impacts, in line with other studies on aquatic metacommunities (e.g., Gálvez et al, 2020; Ramos et al, 2022; Vanschoenwinkel et al, 2007). Species composition and numbers within a kettle hole hydroperiod type (permanent vs. ephemeral) remained relatively stable in subsequent years, suggesting little between‐year variability in composition.…”

“…While our study indicates some impact of the spatial configuration (on our scale of 14.0 km), this explained less variance than environment, pointing towards environmental filtering as the dominant process, a finding in line with most other zooplankton metacommunity studies (e.g., Gálvez et al, 2020; Ramos et al, 2022; Vanschoenwinkel et al, 2007). In this context, recruitment from the local dormant community (dispersal in time) may be of key importance.…”

“…Under this more recent view, the relative impact of these various processes can be quantified using different statistical frameworks, that is, hierarchical modelling of species communities (HMSC) (Ovaskainen et al, 2017), joint species distribution models (JDSM) (Leibold et al, 2022), and variance partitioning, thus disentangling major drivers from processes of less importance for a given metacommunity system (Cottenie, 2005; Legendre, 2008). While aquatic metacommunity studies have been targeted by a number of ecological studies (Cottenie et al, 2003; Gálvez et al, 2020; Gascón et al, 2016; Hill, Heino et al, 2017; Martin et al, 2021; Ramos et al, 2022; Zhao et al, 2017), the temporal aspect is often not included or only limited to a momentary view. It has been recently emphasized that such metacommunity studies should also consider the temporal component (i.e., a higher temporal sampling resolution both within and between multiple years Chaparro et al, 2018; Cottenie & De Meester, 2005; Da Silva et al, 2021; Gray et al, 2012; Horváth et al, 2016, 2019; Kulkarni et al, 2019; Padial et al, 2014; Smit et al, 2017; Wang et al, 2020).…”

Understanding the environmental impact on the assembly of local communities in relation to their spatial and temporal connectivity is still a challenge in metacommunity ecology. This study aims to unravel underlying metacommunity processes and environmental factors that result in observed zooplankton communities. Unlike most metacommunity studies, we jointly examine active and dormant zooplankton communities using a DNA metabarcoding approach to overcome limitations of morphological species identification. We applied two‐fragment (COI and 18S) metabarcoding to monitor communities of 24 kettle holes over a two‐year period to unravel (i) spatial and temporal connectivity of the communities, (ii) environmental factors influencing local communities, and (iii) dominant underlying metacommunity processes in this system. We found a strong separation of zooplankton communities from kettle holes of different hydroperiods (degree of permanency) throughout the season, while the community composition within single kettle holes did not differ between years. Species richness was primarily dependent on pH and permanency, while species diversity (Shannon Index) was influenced by kettle hole location. Community composition was impacted by kettle hole size and surrounding field crops. Environmental processes dominated temporal and spatial processes. Sediment communities showed a different composition compared to water samples but did not differ between ephemeral and permanent kettle holes. Our results suggest that communities are mainly structured by environmental filtering based on pH, kettle hole size, surrounding field crops, and permanency. Environmental filtering based on specific conditions in individual kettle holes seems to be the dominant process in community assembly in the studied zooplankton metacommunity.

“…Our RDA showed that there was considerable difference in zooplankton composition among water bodies during the high waters of 2021, but this season showed abnormal levels that seem to have contributed to this differentiation, while the higher levels during rising waters increased the similarity in environmental parameters and zooplankton composition [36]. The environmental conditions affected the taxa differently [51]. The rotifer Keratella cf.…”

The Western Amazon is a highly biodiverse area. Zooplankton diversity studies in the region have been primarily conducted in Peru and Colombia, with limited research in the Ecuadorian Amazon. To address this gap, our research aimed to enhance taxonomic knowledge and understand zooplankton diversity patterns in the Napo and Pastaza lower basins at different spatial and temporal scales. Two sampling expeditions were conducted in the high waters of 2021 and rising waters of 2022. Dry conditions in 2021 led to lower-than-expected water levels. The study identified 107 zooplankton species, revealing variations in richness and composition between years, lakes, and depth strata. Grande Lake, deeper and wider than Delfincocha, exhibited significant turnover variations across strata in both seasons. Despite a relative longitudinal homogenization between channels and floodplains during high waters, beta diversity across vertical and temporal gradients highlighted complex dynamic zooplankton communities in both lakes. In addition, we include the first records of 44 taxa for the Ecuadorian Amazon and 36 for Ecuador. These findings emphasize the need for targeted research and conservation efforts in the face of escalating environmental threats to the Western Amazon.

“…This theory aims to identify the processes governing metacommunity dynamics, i.e., dispersal limitation, environmental filtering/niche selection, species interaction and stochasticity/ecological drift (Leibold & Chase, 2018; Thompson et al, 2020; Vellend, 2010), to derive predictions on communities under anthropogenic/environmental change (e.g., climate change, pollution, habitat fragmentation; Chase et al, 2020). While the metacommunity theory has been applied to various freshwater systems (e.g., river systems; Ramos et al, 2022; Zhao et al, 2017, pond systems; Gálvez et al, 2020; Cottenie et al, 2003; Kiemel et al, 2022, rock pools; Vanschoenwinkel et al, 2010) and geographical areas (e.g., Gálvez et al, 2020; Cottenie et al, 2003; Kulkarni et al, 2019), temporary ponds in Israel have not yet been analyzed in the context of the metacommunity framework. Understanding the underlying processes could be of great importance in establishing future management strategies, as pond habitats of Israel may shrink due to changes in land use, urbanization, and climate change (Levin et al, 2009).…”

Temporary ponds represent ecologically important habitats that support high species diversity and provide essential ecosystem services, particularly in certain countries surrounding the Mediterranean Sea, where natural lakes are scarce. Israel is located along the southeastern Mediterranean coast and features Mediterranean and arid climatic zones that vary in a variety of meteorological parameters. Temporary ponds are prevalent throughout Israel, including the Mediterranean coast, Mediterranean mountain (i.e., Galilee region), and arid climatic zones. These temporal ponds harbor diverse invertebrate communities that exhibit significant spatial and temporal variations. Among these communities, Monogonont rotifers are notably one of the most diverse and abundant groups. Despite their significant role in aquatic food webs, rotifers are often overlooked in environmental studies, likely due to their small size and difficulties associated with their taxonomy. Resilient resting eggs produced by Monogonont rotifers during periods of unsuitable environmental conditions serve as significant source of propagules that drive the recolonization of temporary ponds upon rehydration, thereby influencing the dynamics of the pond community and metacommunity organization. Here, we examined the diversity of Monogonont rotifers by rehydrating sediment from 30 temporary ponds across Israel. Our analysis identified 39 species, with 25 (64%) of them being reported for the first time in Israel. We found the highest diversity of Monogonont rotifers in the Mediterranean coast region, which is characterized by low altitude, long hydroperiod, and relatively low mean summer daily maximum temperature, while the lowest diversity was found in the Arid region which is characterized by high altitude, short hydroperiod, and high mean summer daily maximum temperature. Our findings suggest that altitude, hydroperiod and mean summer daily maximum temperature are important parameters associated with the observed biodiversity patterns. Our metacommunity analysis further revealed a small contribution of geographic distance (2%) and environmental factors (1%) in shaping rotifer metacommunities. We also found a significant positive correlation among community composition, environmental distance (i.e., Gower’s distance) and geographic distance, possibly due to a linearity in the sampling set-up. Overall, our study highlights the importance of temporary ponds as significant habitats for diverse rotifer communities and emphasizes the need to further study “micro” invertebrate diversity in these unique ecosystems.
