“…Similar productivity‐enhancing interactions also have frequently been observed at terrestrial‐aquatic interfaces (McClain et al 2003, Ballinger and Lake 2006, Capon et al 2013, Garner et al 2015). All these types of interactions can affect functions, such as the productivity of particular land units, both positively (von Hardenberg et al 2001, Bultman et al 2014, Gounand et al 2017) and negatively (Hanski 2015, Chang et al 2021, Kabano et al 2022). In plant communities, net positive interactions have been shown to outweigh the much less frequent negative ones (Wang et al 2019, van der Plas 2019, Turner et al 2020), but corresponding evidence for land‐unit interactions is anecdotal so far (Oehri et al 2020) and awaits systematic investigation.…”

Numerous biodiversity–ecosystem functioning (BEF) experiments have shown that plant community productivity typically increases with species diversity. In these studies, diversity is generally quantified using metrics of taxonomic, phylogenetic, or functional differences among community members. Research has also shown that the relationships between species diversity and functioning depends on the spatial scale considered, primarily because larger areas may contain different ecosystem types and span gradients in environmental conditions, which result in a turnover of the species set present locally. A fact that has received little attention, however, is that ecological systems are hierarchically structured, from genes to individuals to communities to entire landscapes, and that additional biological variation occurs at levels of organization above and below those typically considered in BEF research. Here, we present cases of diversity effects at different hierarchical levels of organization and compare these to the species‐diversity effects traditionally studied. We argue that when this evidence is combined across levels, a general framework emerges that allows the transfer of insights and concepts between traditionally disparate disciplines. Such a framework presents an important step towards a better understanding of the functional importance of diversity in complex, real‐world systems.

“…Almost 60% of the global ecosystem is deteriorating at an unprecedented rate, caused by the surpassing of demand compared to supply and their spatial mismatches (MEA, 2005;Bagstad et al, 2013). Therefore, how to effectively manage ecosystems to minimize the supply-demand mismatches of ESs is critical for improving human well-being and sustainable development (Furst et al, 2013;Chang et al, 2021).…”

“…Fu et al (2017) provided management suggestions for different subregions by analyzing the impacts of land use change and climate change on ESs, such as planting grasslands with high coverage in the oasis zone and establishing protected areas in the mountain and desert zones. However, most existing studies have focused on the supply side but neglected the demand side, which has a closer connection to human society (Meng et al, 2020;Chang et al, 2021).…”

“…Thus, zoning management would be an effective method to improve human well-being while maintaining ecosystem function and resilience, especially for regions with high spatial heterogeneity (Xu L.-X. et al, 2019;Zeng et al, 2020;Chang et al, 2021). Most existing studies tended to classify zones through either environmental characteristics or ecological function and ESs.…”

The imbalance between the supply and demand of ecosystem services (ESs) is one of the main reasons for ecological degradation, which significantly impacts human well-being and ecological safety. Spatial heterogeneity of ES supply–demand, ES tradeoffs, and the socioecological environment calls for zoning management, while few studies have combined the above three aspects in dividing management zones and proposed strategies. Using the City Belt along the Yellow River in Ningxia in northwestern China as a case study, this study quantified the supply and demand for five key ESs (crop production, carbon sequestration, nutrient retention, sand fixation, and recreational opportunity), analyzed ES tradeoffs/synergies and bundles through correlation analysis and the self-organizing map (SOM) method, and investigated their socioecological driving mechanisms through a random forest model and the SOM method. Management zones were proposed and differentiated suggestions were provided through overlaying ES bundles and driver clusters. The results suggested that crop production, carbon sequestration, and nutrient retention mostly correlated to the same intrinsic ecological process, resulting in consistent synergies among these three ESs at both supply and demand sides. On the contrary, the variance in interactions between the two ESs of sand fixation and recreational opportunity and the other three ESs is due to the low similarity of their intrinsic ecological processes and external driving mechanisms. Fourteen socioecological factors could effectively explain the spatial heterogeneity of ES supply, demand, and match degree. Fourteen management zones with similar ecological problems and socioecological environments were delineated, and differentiated suggestions were provided for each zone. Adopting both ES characteristics and the socioecological environment into zoning management could effectively detect ecological problems and help to promote management suggestions in different socioecological contexts. This framework could offer new insights for integrating ESs into actual decision-making and ecosystem management.

“…information is used for many different applications. These include biodiversity assessments , land-use planning to reduce water pollution (Chang et al, 2021), predicting future urbanisation impacts and management (Croft-White et al, 2017), riparian zone protection (Dala-Corte et al, 2016), assessing effects of water quality (Dudley et al, 2020) and hydrological changes (Gergel et al, 2002), and methods to maximise ecosystem service values (Hoque et al, 2020). Social and economic conditions, political policies, and climate-induced factors influence LULC (Goble and van der Elst, 2013;Adams et al, 2020) and are collectively influenced and compounded by growing populations (Biggs and Scholes, 2002).…”

Decadal changes in land-use, water quality and fish assemblages in a KwaZulu-Natal urban and non-urban estuary.

Globally, estuaries are recognised as highly dynamic environments which support diverse and productive flora and fauna, and provide numerous goods and services for human wellbeing.These systems are under threat from growing coastal populations that demand the transformation of natural land to accommodate urbanisation, agriculture, harbour, and infrastructure developments. Direct and indirect land-use/land-cover (LULC) changes adversely affect estuarine water quality, directly impacting estuarine biota such as fishes.While the short links between these components are known, few studies have attempted to integrate these links, particularly within the South African context. Therefore, this study aimed to integrate different levels of assessment (LULC and estuarine water quality) to describe changes in estuarine fish ecology over space and time. The study compared two permanently open estuaries in KwaZulu-Natal with distinct land-cover types, namely the uMgeni and uMlalazi estuaries. The uMgeni Estuary is surrounded by urban features and is situated in a highly developed catchment, whereas the uMlalazi is near-natural, with some surrounding agricultural areas.Historical land-cover imagery from the estuary to the 20 m topographical contour (inclusive of the Estuary Functional Zone), the estuary catchment land-cover, water quality and ichthyofauna data were collected. Land-cover types were grouped into eight categories and 42 feature classes based on modifications to the South African National Land Cover system, the United States Geological Survey and the Coastal Change Analysis Program. Multivariate statistical analysis identified two distinct groupings of land-cover types, Period 1 (before 1989) and Period 2 (during and after 1989). This period factor was then further used throughout the study to determine associated (temporal) responses in water quality and fish assemblages. Strong negative correlations were observed between dissolved oxygen and artificial land-cover types in the uMgeni Estuary. The results suggested that the uMgeni Estuary receives nutrient inputs from various urban activities, which reduce oxygen levels within the water column. Alterations to the hierarchical ichthyofauna structure in the uMgeni occurred on a year to year basis, relative to these anthropogenic impacts. In contrast, good water quality likely associated with fewer developments within the Estuarine Functional Zone has allowed the hierarchical fish structure in the uMlalazi Estuary to remain the same over time, although minor species level differences have occurred.
