Network properties, species abundance and evolution in a model of evolutionary ecology

Abstract: We study the evolution of the network properties of a populated network embedded in a genotype space characterized by either a low or a high number of potential links, with particular emphasis on the connectivity and clustering. Evolution produces two distinct types of network. When a specific genotype is only able to influence a few other genotypes, the ecosystem consists of separate noninteracting clusters (i.e. isolated compartments) in genotype space. When different types may influence a large number of ot… Show more

“…This version of the Tangled Nature model succeeded its predecessor (Collobiano, Christensen, & Jensen, 2003) (Anderson & Jensen, 2005) by introducing correlations into the inheritance process. Here, we shall present the construct of the model whilst summarising the correlative effects.…”

“…Dependendo da sobreposição adequada entre os alelos de um locus gênico de dois indivíduos, uma interação poderá ocorrer. Ao adicionar mutação e recombinação destes genes, esses modelos podem simular processos de seleção e diversificação in silico, ou seja, dentro de um ambiente virtual de computador (Hraber and Milne 1997, Recknagel 2003, Anderson & Jensen 2005. Outro exemplo é o modelo Tangled Nature (Christensen et al 2002, Hall et al 2002, que utiliza uma abordagem similar ao Webworld, mas ao invés da espécie, é o indivíduo que possui uma série de L atributos, cada um com dois valores possíveis: ±1.…”

“…Much work has been done within ecology to study the dynamics of ecological networks and the way that the structure of those networks and distribution of interaction types can affect the outcome for the whole community (e.g. [20,21,22,23,24,25]). As industrial networks or ecosystems undoubtedly share some of the structural properties of biological ecosystems it seems likely that some of the tools of ecological modelling could be usefully adapted to industrial ecology.…”
