“…Species in ecosystems rarely live in isolation, but depend on different types of interactions to coexist with other species, such as trophic, competitive, and mutualistic interactions (Godoy, 2019 ). The combined effects of different interactions between species have been shown to play an important role in, but not limited to, maintaining ecosystem stability (Rohr et al., 2014 ; Thébault & Fontaine, 2010 ; Xu et al., 2023 ), species diversity (Losapio et al., 2021 ; Pascual‐García & Bastolla, 2017 ), co‐evolution (Bronstein, 2009 ; Guimaraes et al., 2017 ), and species invasion (Duan et al., 2022 ; Legault et al., 2020 ). The study of the coexistence of specialist and generalist species under different types of interactions can not only help to understand the universal characteristics of species interactions but also significantly improve our understanding of the division of ecological functions among species (Pasquaretta & Jeanson, 2018 ).…”

As an ecological strategy for species coexistence, some species adapt to a wide range of habitats, while others specialize in particular environments. Such ‘generalists’ and ‘specialists’ achieve normal ecological balance through a complex network of interactions between species. However, the role of these interactions in maintaining the coexistence of generalist and specialist species has not been elucidated within a general theoretical framework. Here, we analyze the ecological mechanism for the coexistence of specialist and generalist species in a class of mutualistic and competitive interaction ecosystems based on the network dimension reduction method. We find that ecological specialists and generalists can be identified based on the number of their respective interactions. We also find, using real‐world empirical network simulations, that the removal of ecological generalists can lead to the collapse of local ecosystems, which is rarely observed with the loss of ecological specialists.

“…However, most current works ignore the influence of a space factor. In fact, aviation networks [27], transportation networks [28], wireless sensor networks [29], and swarming networks [30] are all limited by spatial locations. In these networks, each node has a fixed spatial location, and link length is limited.…”

With the rapid development of networks, the traffic in the networks has increased sharply, resulting in frequent congestion, especially in spatial networks, such as the railway network, aviation network, and sensor network, and congestion not only affects the user’s experience but also causes serious economic losses. Therefore, in this paper, we effectively identify the high-load nodes in spatial networks by considering harmony centrality and degree. On this basis, we design the HD routing strategy by avoiding these key nodes, which can enhance the traffic throughput of spatial networks efficiently. The results provide new ideas and directions for the design of routing strategies for spatial networks.
