“…At the medium water depth, the community biomass was, on average, the highest compared to that at other water depths, and the insignificant species richness-biomass relationship likely resulted from the competitive exclusion (i.e., two species competing for the same limited resource may not coexist) between dominant and subordinate species (Huston, 1997;Tilman et al, 1997). In deep water, the numbers of species reduced sharply due to a further decrease in the underwater light availability, and only a few low-light tolerant species, i.e., P. maackianus, C. demersum, and V. natans, were able to colonize (Wen et al, 2022). These species can adapt to low-light conditions through different adaptive strategies (e.g., P. maackianus allocates more biomass to stems and forms dense canopies, while V. natans increases both the leaf chlorophyll content and leaf biomass) and occupy different water-column spaces (Chen et al, 2016;He et al, 2019;Wen et al, 2022).…”

In addition, P. maackianus and M. spicatum can provide feedback to improve the environmental conditions, such as water clarity by inhibiting the growth of phytoplankton and periphyton through allelopathy or nutrient competition (Liu et al, 2020) and facilitate the growth of other species that are less tolerant to low-light conditions.…”

The effect of biodiversity on ecosystem productivity has been a controversial issue in ecological research. The species richness–productivity relationship is highly variable in natural ecosystems, with a positive relationship being one of the most commonly observed relationships. Previous regional studies from terrestrial ecosystems have demonstrated that environmental gradients can regulate the species richness–productivity relationship. However, how this relationship varies in freshwater ecosystems across spatial environment gradients remains unclear. In this study, we propose that the species richness–productivity relationship can be modulated by the water depth. Here, we surveyed the submerged macrophyte community structure by establishing 24 transects and 642 quadrats in Erhai Lake, Yunnan Plateau, China. Our findings highlight that the species richness–productivity relationship gradually changed from slightly positive to strongly positive as the environment became more light-limited with the increasing water depth, supporting the stress-gradient hypothesis. The results from this study provide new insights into the biodiversity–ecosystem functioning relationships and in managing lake macrophyte communities and productivity.

“…However, extreme water quantity fluctuations often negatively affect vegetation composition (van Geest, Coops, et al, 2005). The amplitude of water quantity change can influence ecological dynamics such as nutrient availability, plant development, species competition, and species range (Krolov a et al, 2013;van Geest, Wolters, et al, 2005;Wen et al, 2022), highlighting another complex interaction between water quantity fluctuations and biological water quality parameters. As many of the relationships between lacustrine water quantity and biological water quality parameters are ambiguous, satellite remote sensing offers a promising way forward for improving our understanding of these complex and intertwined systems.…”

The quantity and quality of surface water are inherently connected yet are overwhelmingly studied separately in the field of remote sensing. Remotely observable water quantity (e.g., water extent, water elevation, lake/reservoir volume, and river discharge) and water quality (e.g., color, turbidity, total suspended solids, chlorophyll a, colored dissolved organic matter, and temperature) parameters of inland waterbodies interact through a series of hydrological and biogeochemical processes. In this review, we analyzed trends in remote sensing publications to understand the prevalence of studies on the quantity versus quality of open‐surface inland waterbodies (rivers, streams, lakes, and reservoirs) as well as identified opportunities for integrating both water quality and quantity sensing in future work. Our bibliometric analysis found that despite the increasing number of publications using remote sensing for inland waterbodies, few studies to date have used remote sensing tools or approaches to simultaneously study water quantity and quality. Ultimately, by providing insights into potential integration of the water quality and quantity studies, we aim to identify a pathway to advance the understanding of inland water dynamics and freshwater resources through remote sensing.This article is categorized under: Water and Life > Methods Science of Water > Water Quality Water and Life > Nature of Freshwater Ecosystems Science of Water > Methods
