WebThe utilitarian redundancy model (URM) enables a simple and objective evaluation of the functionality of knowledge systems based on species known to perform similar functions. It emerges from the redundancy model in ecology that analyzes, from a functional perspective, the use of natural resources by human populations. WebApr 10, 2024 · Much of the data available to ecologists consists of species occurrences, which in turn have sparked the development of statistical models to analyse such data (Bailey et al. 2014).Due to their ability to model species occurrences while accounting for imperfect detection, occupancy models have become widely used in ecology (Bailey et al. …

WebJan 30, 2024 · There is a growing body of evidence that high-diversity systems may have enhanced ecosystem stability and resilience potential. These benefits can arise due to the number and strength of species interactions (McCann et al. 1998) and redundancy in traits and trophic roles (Menge 1983, Peterson et al. 1998, Steneck et al. 2002, Snyder et al. 2008).
