Inappropriate human activities contribute to the degradation of ecosystems in arid or semi-arid regions. Therefore, emphasizing importance strategies for restoring vegetation these areas cannot be overstated. However, there has been insufficient research on how develop effective restoration at minimal cost. This paper addresses this gap by studying optimizing spatiotemporal distribution through local and boundary controls can reduce level desertification pattern structures, thereby facilitating recovery land vegetation. The results indicate that depends proportion number activity areas, with a trade-off between them. Furthermore, consistent conclusions were obtained circular regions, demonstrating robustness approach shapes. aims offer new insights into prevention catastrophic ecosystem changes from perspective optimal control.

Many systems on our planet are known to shift abruptly and irreversibly from one state another when they forced across a "tipping point," such as mass extinctions in ecological networks, cascading failures infrastructure systems, social convention changes human animal networks. Such regime demonstrates system's resilience that characterizes the ability of system adjust its activity retain basic functionality face internal disturbances or external environmental changes. In past 50 years, attention was almost exclusively given low dimensional calibration their functions indicators early warning signals without considerations for interactions between components. Only recent taking advantages network theory lavish real data sets, scientists have directed interest real-world complex networked multidimensional function indicators. This report is devoted comprehensive review different domains, ecology, biology, infrastructure. We cover related research about empirical observations, experimental studies, mathematical modeling, theoretical analysis. also discuss some ambiguous definitions, robustness, resilience, stability.

Vegetation Turing patterns play a critical role in the ecological functioning of arid and semi-arid ecosystems. However, long-range spatial features these have been neglected compared to short-range like patch shape wavelength. Drawing inspiration from hyperuniform structures material science, we find that vegetation pattern exhibits dispersion similar hyperuniformity. As degree hyperuniformity increases, so does water-use efficiency vegetation. This finding supports previous studies suggest represent spatially optimized self-organization ecosystems for water acquisition. The Turing-type significant slowing down near tipping point, indicating non-negligible transient dynamical behavior. Reduced rainfall not only decreases resilience steady state ecosystem but also slows rate optimization long regimes. We propose indicates after strong, short-term disturbances. Spatially heterogeneous disturbances reduce lead longer recovery times than homogeneous maintain

Large-scale regular vegetation patterns are common in nature, but their causes disputed. Whereas recent theory focuses on scale-dependent feedbacks as a potentially universal mechanism, earlier studies suggest that many spatial result from territorial interference competition between colonies of social-insect ecosystem engineers, leading to hexagonally overdispersed nest sites and associated vegetation. Evidence for this latter mechanism is scattered throughout decades disparate literature lacks unified conceptual framework, fueling skepticism about its generality debates over the origins patterned landscapes. We review these mechanisms debates, finding evidence spotted gapped generated by ants, termites, other subterranean animals globally widespread, locally important functioning, consistent with models intraspecific territoriality. Because regular-pattern formation not mutually exclusive can coexist interact at different scales, prevailing theoretical outlook self-organization ecology must expand incorporate dynamic interplay multiple processes.

Microscopic-scale processes significantly influence benthic marine ecosystems such as coral reefs and kelp forests. Due to the ocean's complex dynamic nature, it is most informative study these in natural environment yet inherently difficult. Here we present a system capable of non-invasively imaging seafloor environments organisms situ at nearly micrometre resolution. We overcome challenges underwater microscopy through use long working distance microscopic objective, an electrically tunable lens focused reflectance illumination. The diver-deployed instrument permits studies both spatial temporal algal colonization overgrowth bleaching corals, well polyp behaviour interspecific competition. By enabling observations previously unattainable scales, this can provide important new insights into micro-scale that shape observed patterns much larger scales.

Short-scale interactions yield large-scale vegetation patterns that, in turn, shape ecosystem function across landscapes. Fairy circles, which are circular patches bare of within otherwise continuous landscapes, characteristic features semiarid grasslands. We report the occurrence submarine fairy circle seascapes seagrass meadows and propose a simple model that reproduces diversity observed these ecosystems as emerging from plant meadow. These include two extreme cases, meadow landscape, along with intermediate states range persistent but isolated or solitons, to multiple banded vegetation, "leopard skin" consisting dotted patches.
