“…In fact, the latitude of study lakes and the monthly mean air temperature were strongly negatively correlated (Pearson's r = -0.97, p < 0.001). A previous study on various European lakes showed that environmental characteristics such as dimension, turbidity, nutrient enrichment, connectivity, and the presence of non-native sh can alter the rate of sh assemblage change over a latitude gradient (Menezes et al 2023). Our ndings demonstrate that the presence of invasive species is a driving force of the variation in community structure along a latitudinal gradient.…”

The biological invasion of aquatic ecosystems has negative effects on competition and predation. These ecological impacts on native communities may also affect two processes that are important in determining community structures, namely, the environmental and spatial processes. Here, we using lake fish community composition estimated through environmental DNA metabarcoding, we examined the effects of invasive species on the community structure determination processes in lakes. The objective was to describe the relationship between fish diversity and invasive species in lakes and to estimate the explanatory power of environmental factors with regard to variation in community composition among lakes using direct gradient analysis, i.e., distance-based redundancy analysis. Further, we employed variation partitioning to examine how the explanatory power of environmental factors and spatial structures for variation in community composition varied with the presence of invasive species. The environmental slope analysis showed that the explanatory power of environmental factors for variation in community composition among lakes was higher in communities without invasive species. A comparison of the relative importance of environmental factors and spatial structure in determining community composition between communities, excluding invasive species, and communities with invasive species showed that the relative importance of environmental factors was higher in communities without invasive species, highlighting the possibility of differences in dispersal abilities between native and invasive species.

Better understanding of the responses of algal biodiversity to multiple pressures, such as climate warming and eutrophication, is a key issue in aquatic ecology. Alpha and beta diversity may have various patterns over temporal scales, especially in the Anthropocene, when external pressures became more multifaceted. However, the limited availability of historical data hampers the exploration of algal biodiversity through time. Recently, sediment DNA has emerged as a potential tool for elucidating temporal patterns in algal communities. Here, we used sediment DNA to reconstruct temporal turnover and diversity of algal communities in four remote lakes in northern China over the past 200 years. Furthermore, to distinguish the contributions of possible influencing environmental factors, we conducted structural equation modelling. Our results revealed that algal communities have experienced rapid shifts since the Anthropocene, characterized by increased alpha diversity and decreased temporal beta diversity. Warmer climate and eutrophication were associated with changes in alpha diversity, while temporal environmental variation was associated with temporal beta diversity. This study revealed opposing patterns in alpha and beta diversity for algal communities, possibly caused by warming, eutrophication and lower temporal environmental variation, respectively. While climatic factors played a major role in remote lakes with a natural environment, lakes that are more human impacted may be more structured by nutrient‐related factors. Under climate warming and intensified human activities, remote lakes may encounter complex pressures in the near future. Our findings offer valuable insights into patterns in aquatic biodiversity and possible factors underlying multiple pressures.
