It argues that much of the resilience literature covers existing ground in that existing engineering systems stability ideas are being reinvented. The review follows modern control systems theory as the …

WebOct 12, 2024 · Three matrices were developed (ranked by island size, isolation, and habitat type, respectively) and evaluated for both nestedness and modularity. Island size produced the greatest degree of nestedness, even when accounting for variation in species richness across islands. None of the island characteristics exhibited patterns of modularity.

WebWe propose that the relationship between nestedness and habitat structure is an outcome of individual variation in the vertical space and food resource use by G. agilis in sites with thick and spaced trees. Moreover, individual specialization in resource‐rich and population‐dense periods possibly increased the network modularity of G. agilis.

These differences in community and network structures of epiphytes and endophytes may be caused by spatial niche partitioning, indicating their underlying ecological and …
