“…Another important refuge for benthic invertebrates, especially during early development phases, is the hyporheic zone [113]. This area constitutes a transition between the surface stream and groundwater [114,115]. Hydrologically, the hyporheic zone can also be defined as the interstitial spaces adjacent to the streambank and below the streambed, spaces that are saturated and contain some of the channel water [116].…”

Urbanisation alters the natural hydromorphology of streams, affecting aquatic communities and ecological quality. Increasing efforts have been put into the rehabilitation of urban streams due to their importance for urban sustainability. Despite these efforts, many projects fail to achieve the improvement of aquatic communities. This study aims to provide specific recommendations to enhance the biological rehabilitation of urban streams by reviewing: (i) the impacts of urbanisation and climate change on urban stream hydrology, (ii) the responses of invertebrate assemblages to alterations in the hydrology and morphology of streams, and (iii) the hydromorphological rehabilitation measures applied to streams and their effect on invertebrate communities. This review found that commonly employed measures of habitat heterogeneity enhancement (such as the addition of meanders, boulders, and artificial riffles) are not enough to improve invertebrate communities. On the other hand, the most effective measures are those leading to the re-establishment of natural hydrological patterns and good water quality. Ultimately, an integrated ecohydrological approach that considers the entire watershed and its interactions between ecosystems and anthropological activities is the key to managing and rehabilitating urban streams.

“…Landscapes are not a key feature of the current critical zone models. However, Chamorro, Giardino, Granados‐Aguilar, and Price () and Luo et al. () have recently reviewed the progress, similarities and opportunities for integration of the depth modeling from critical zone science and the spatial considerations of landscape ecology to better inform the sustainable management of multi‐functional landscapes.…”

The need for sustainable intensification of agricultural production has ushered in a growing awareness of soil health and a requirement to identify with some certainty how changes to land management will affect soil. From an agricultural perspective, the active management of soil health needs to balance the production of a healthy and profitable crop with environmental protection and improvement. However, the extreme spatial and temporal heterogeneity of soils, and the complexity of biological, physical and chemical interactions therein, makes predicting management effects on soil health challenging. Although the general principles underlying effects on soil health are well understood, they still need interpretation in a local context and the inclusion of site‐specific details. Approaches from landscape ecology provide a potential framework to integrate consideration of the structural (pools, patterns), dynamic and functional (processes, flows) aspects of the soil system. These approaches allow the crucial transition from a “descriptive and general” understanding toward a “detailed and site‐specific” prediction to be made. Using this conceptual framework, we have taken knowledge of the effects of fixed site factors (soil type and climatic zone), cropping systems and farm management practices on a range of soil physical, chemical and biological parameters for UK lowland agricultural systems, and have developed a predictive framework that shows semi‐quantitatively the effects of typical management choices on soil health and crop yield.

“…In many ways, this data-driven development of landscape indicators led us to neglect the crucial issues related to the indicators' ecological implications (Jackson et al, 2000). What are these indicators meant to indicate, and how the interaction between patterns and ecological processes are always unclear (Chamorro et al, 2015;Wu, 2006). We argue that the premise of indicators application is a clear theory base and ecological implications, which were to make them easier to interpret.…”

Spatiotemporal variation indicators for vegetation landscape stability and processes monitoring of semiarid grassland coal mine areas

Terrestrial ecosystems are always changing due to natural and anthropogenic factors. Many studies have described the changes through landscape indicators, but landscape stability and processes are considered less in existing studies. Therefore, it is essential to establish effective indicators to detect the landscape changes and stability. In this study, three indicators were proposed to characterize the vegetation landscape stability and processes based on the system fluctuation and stability theory, which were applied to a typical semiarid grassland coal mine region. The indicators were calculated based on the normalized difference vegetation index (NDVI) time-series data griding, which characterized the NDVI central tendency, heterogeneity, and relative fluctuation in each grid through spatio-temporal analysis. The study has confirmed that the dynamic process and stability of each landscape type identified through the three indicators were in good agreement with the on-site conditions. Firstly, the natural grassland was in a macro-stable state generally. Secondly, partial regions associated with open-pit mining regions were identified as severe disturbance regions, with grassland entirely replaced by the bare land, while the grasslands surrounding were identified as mild disturbance regions, with the stability decreasing. Finally, the surface subsidence was characterized by ground surface deformation and fracture, which causes mild disturbance to the grassland landscape. However, the surface collapse, characterized by subsidence pits, has always caused grassland instability. Moreover, the reclaimed grassland is prone to deterioration and lack of stability under severe natural conditions such as drought. We suggest this study could be used to identify the stability and dynamic trend of grassland landscape.
