(2004) examine the question from an evolutionary biology perspective; Demetrius and Manke (2005) present methods which can be applied to ecological networks (e.g., food webs); Juh´asz-Nagy (1976, 1984, 1993); Juh´ asz-Nagy and Podani (1983) was the first to develop a coherent information-theoretical framework for summarizing various aspects of spatial complexity in plant communities as a function of scale.
