Monitoring for conservation

McDonald-Madden (2010; TREE): Is monitoring worthwhile? The benefits of the information gained from monitoring do not always outweigh the costs of acquiring it. For example, if one’s management strategy is not dependent upon the state of the system, one does not need to monitor. Or if one is unsure about the cause of decline, it may make more sense to spend resources researching that rather … Continue reading Monitoring for conservation

Stability in large webs

Allesina & Tang (2012 Nature): An extension of analytic, Wigner semicircle theorem-like, stability criteria to predator-prey, competition and mutualism cases. Finds predator-prey interactions permit stability in networks as large and complex as real ones. Hierarchy is: competition-mutualism mixture, random, predator-prey. Finds that stability is less likely when both predator-prey networks and mutualistic networks are given more realistic structure (i.e. niche-model structure and nestedness respectively).
