Low shifts in salinity determined assembly processes and network stability of microeukaryotic plankton communities in a subtropical urban reservoir

Microbiome, Journal Year: 2021, Volume and Issue: 9(1)

Published: June 3, 2021

Abstract Background Freshwater salinization may result in significant changes of microbial community composition and diversity, with implications for ecosystem processes function. Earlier research has revealed the importance large shifts salinity on physiology ecology, whereas studies effects smaller or narrower microeukaryotic inland waters are scarce. Our aim was to unveil assembly mechanisms stability plankton networks at low salinity. Results Here, we analyzed a high-resolution time series data from an urban reservoir subtropical China over 13 consecutive months following one periodic change ranging 0 6.1‰. We found that (1) increase altered led decrease (2) influenced primarily by regulating deterministic-stochastic balance, deterministic becoming more important increased salinity, (3) core subnetwork robustness higher low-salinity levels, while satellite subnetworks had greater medium-/high-salinity levels. results suggest influence rather than successional time, is driving force shaping dynamics. Conclusions findings demonstrate salinities, even small increases sufficient exert selective pressure reduce diversity alter mechanism network stability. provide new insights into ecology impacts microbiotas architecture.

Future phytoplankton diversity in a changing climate

Nature Communications, Journal Year: 2021, Volume and Issue: 12(1)

Published: Sept. 10, 2021

The future response of marine ecosystem diversity to continued anthropogenic forcing is poorly constrained. Phytoplankton are a diverse set organisms that form the base ecosystem. Currently, ocean biogeochemistry and models used for climate change projections typically include only 2-3 phytoplankton types are, therefore, too simple adequately assess potential changes in plankton community structure. Here, we analyse complex model with 35 evaluate composition, turnover size structure over 21st century. We find rate becomes faster during this century, is, increasingly unstable change. Combined alterations diversity, our results imply loss ecological resilience likely knock-on effects on productivity functioning environment.

Advancing our understanding of ecological stability

Abstract The concept of ecological stability occupies a prominent place in both fundamental and applied research. We review decades work on the topic examine how our understanding has progressed. show that remained fragmented is limited largely to simple or simplified systems. There been profusion metrics proposed quantify stability, which only handful are used commonly. Furthermore, studies typically one two at time response single perturbation, with some main environmental pressures today being least studied. argue we need build existing consensus strong theoretical foundation better understand its multidimensionality interdependencies between metrics, levels organisation types perturbations. Only by doing so can make progress quantification theory practice, eventually more comprehensive ecosystems will respond ongoing change.

Biodiversity promotes ecosystem functioning despite environmental change

Ecology Letters, Journal Year: 2021, Volume and Issue: 25(2), P. 555 - 569

Abstract Three decades of research have demonstrated that biodiversity can promote the functioning ecosystems. Yet, it is unclear whether positive effects on ecosystem will persist under various types global environmental change drivers. We conducted a meta‐analysis 46 factorial experiments manipulating both species richness and environment to test how drivers (i.e. warming, drought, nutrient addition or CO 2 enrichment) modulated effect multiple functions across three taxonomic groups (microbes, phytoplankton plants). found increased in ambient manipulated environments, but often not same degree. In particular, were larger stressful environments induced by drivers, indicating high‐diversity communities more resistant change. Using subset studies, we also mainly driven interspecific complementarity these over time environments. Our findings support conservation as key strategy for sustainable management face

Unifying the concepts of stability and resilience in ecology

Journal of Ecology, Journal Year: 2021, Volume and Issue: 109(9), P. 3114 - 3132

Abstract Characterizing how ecosystems are responding to rapid environmental change has become a major focus of ecological research. The empirical study stability, which aims quantify these ecosystem responses, is therefore more relevant than ever. Based on historical review and bibliometric mapping the field we show that two main schools relating stability—one focusing systems close their equilibrium other non‐equilibrium behaviour—have developed in parallel leading divergence both concepts definitions. We synthesize expand previous frameworks capitalize latest developments build towards an integrated framework by elaborating overarching concept stability its properties. Finally, broad applicability our work demonstrated cases. Synthesis .

Meta‐analysis shows both congruence and complementarity of DNA and eDNA metabarcoding to traditional methods for biological community assessment

Molecular Ecology, Journal Year: 2022, Volume and Issue: 31(6), P. 1820 - 1835

Abstract DNA metabarcoding is increasingly used for the assessment of aquatic communities, and numerous studies have investigated consistency this technique with traditional morpho‐taxonomic approaches. These individual to assess diversity community structure organisms both in marine freshwater systems globally over last decade. However, a systematic analysis comparability effectiveness DNA‐based across all these has hitherto been lacking. Here, we performed first meta‐analysis available comparing methods measure biological key groups, including plankton, microphytobentos, macroinvertebrates, fish. Across 215 data sets, found that provides richness estimates are consistent those obtained using methods, at local regional scale. also generates species inventories highly congruent Contrastingly, microphytobenthos macroinvertebrates by showed pronounced differences missing some taxa but same time detecting otherwise overseen diversity. The method generally sufficiently advanced study composition fish communities replace more invasive methods. For smaller organisms, like plankton microphytobenthos, may continue give complementary rather than identical compared Systematic comparable collection will increase understanding different aspects complementarity, adequate interpretation results.

High microbial diversity stabilizes the responses of soil organic carbon decomposition to warming in the subsoil on the Tibetan Plateau

Abstract Soil microbes are directly involved in soil organic carbon (SOC) decomposition, yet the importance of microbial biodiversity regulating temperature sensitivity SOC decomposition remains elusive, particularly alpine regions where climate change is predicted to strongly affect dynamics and ecosystem stability. Here we collected topsoil subsoil samples along an elevational gradient on southeastern Tibetan Plateau explore ( Q 10 ) relation changes communities. Specifically, tested whether would be more sensitive warming when diversity low. The estimated value ranged from 1.28 1.68, 1.80 2.10 subsoil, respectively. highest was observed at lowest altitude forests topsoil, meadow subsoil. Variations were closely related properties. In ratio gram‐positive gram‐negative bacteria (G+:G−) predominant factor associated with altitudinal variations . showed resilience (both whole community major groups) fungi higher. Our results partly support positive biodiversity‐ecosystem stability hypothesis. Structural equation modeling further indicates that composition, which affected by pH. Collectively our provide compelling evidence plays important role stabilizing montane ecosystems. Conservation belowground therefore great maintaining processes under high‐elevation Plateau.
