“…Approximately half of the interdisciplinary studies included temporal dynamics ( n = 6), and these studies focused on perennial streams (Da Silva, Lansac‐Tôha, Lansac‐Tôha, Sales, & de Sousa Rocha, 2021; Lansac‐Tôha et al, 2019; Tonkin et al, 2018), river floodplains (Padial et al, 2014), intermittent ponds (Galvez et al, 2020), and intermittent streams (Datry et al, 2016). Even within the narrow set of interdisciplinary studies, a variety of analytical methods was used, including variation partitioning (Da Silva et al, 2021; Galvez et al, 2020; Padial et al, 2014), elements of metacommunity structure (Tonkin et al, 2018), and beta diversity components (Lansac‐Tôha et al, 2019). Logue et al (2011) previously reviewed empirical approaches to metacommunities and focused on variation partitioning and elements of metacommunity structure.…”

Metacommunity ecology represents a framework for identifying linkages between environmental heterogeneity, spatial processes, and local communities of organisms. Despite advancements in metacommunity theory, there remains a need to understand temporal dynamics of multi‐taxa metacommunities in variable ecosystems such as intermittent streams. We present a review of literature, three recent conceptual models, and a case study regarding metacommunity temporal dynamics in intermittent streams. The literature review revealed that the cumulative number of studies addressing temporal dynamics in aquatic metacommunities steadily increased between 2012 and 2020. Intermittent streams were the fourth‐most commonly studied ecosystem and interdisciplinary studies involving multiple taxa were the third‐most common taxonomic focus. The most common analytical method was variation partitioning, and analysis of beta diversity components surpassed both distance decay and elements of metacommunity structure as the second‐most used method from 2018 to 2020. Three recent conceptual models describing metacommunity dynamics in intermittent streams predict: (a) higher local species richness (i.e., alpha diversity) during rewetting and wet hydrologic phases, (b) stronger effects of dispersal over environmental sorting during the rewetting and wet phases, and (c) emergence of primarily nested structures during the wet hydrologic phase. When tested in a case study focused on microbes, aquatic invertebrates, and fishes, each of these predictions were partially, but not completely supported. Our results reveal expanding interest in temporal aspects of aquatic metacommunity structure and highlight how research in intermittent streams is poised to simultaneously advance basic metacommunity ecology and applied conservation biology through continued refinement of new and existing conceptual syntheses.

“…Several studies have shown that environmental changes (nutrient enrichment) have a marked impact on the growth, community composition, density, and diversity of zooplankton in aquatic ecosystems [19][20][21]. Recently, researchers have shown an increased interest in variation in community composition among sites (beta diversity), which is also considered a very practical tool for exploring the effects of environmental factors on zooplankton communities [22,23]. Data from several studies suggest that the construction of dams or flooding of river-floodplain systems may induce environmental changes, which in turn could alter zooplankton community structures and decrease zooplankton beta diversity [24,25].…”

Beta diversity represents the spatial or temporal variation of species diversity among sampling sites and may be composed of two elements: turnover (Brepl, replacement of species assemblages) and nestedness (Brich, loss or gain of species assemblages). Knowledge of the mechanisms driving beta diversity contributes to an understanding of the variation in aquatic ecosystem community structures. We sampled zooplankton assemblages at 24 sites in 11 rivers in Shanghai City and conducted a nutrient addition experiment to elucidate the effects of various environmental variables on the community structure and beta diversity patterns of the zooplankton. The zooplankton assemblages in the rivers differed significantly at ammonia nitrogen (NH3-N) concentrations below (Group I) and above (Group II) 1.03 mg·L−1. The nutrient addition experiment further demonstrated that the composition of the zooplankton assemblages changed markedly along an ammonia concentration gradient (0.2 to 5.0 mg N·L−1). The total beta diversity of Group I was considerably higher than that of Group II, indicating that high nutrient (ammonia) pollution led to biotic homogeneity. Overall, turnover was the key factor determining the total beta diversity of the two groups, suggesting the key importance of replacement of zooplankton assemblages. Furthermore, we found a correlation between environmental factors (mainly nitrogen content) and the beta diversity of zooplankton, and beta diversity (Brepl and Btotal) decreased with increasing trophic state. These findings provide further insight into the changing characteristics of the beta diversity patterns of zooplankton in river networks and may help to guide managers dealing with conservation strategies for aquatic biodiversity preservation in urban river ecosystems.

“…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).…”

DNA metabarcoding reveals impact of local recruitment, dispersal, and hydroperiod on assembly of a zooplankton metacommunity

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.
