Evolution and the Regulation of Environmental Variables

by Hywel Williams, Jason Noble , 2005
"... Abstract. The idea that the biota can regulate the abiotic components of their environment to levels suitable for life has attracted criticism from neo-Darwinian theorists but is still a viable hypothesis. Here we present a model, similar to Daisyworld [1] but more general, which allows for a more e ..."

Abstract. The idea that the biota can regulate the abiotic components of their environment to levels suitable for life has attracted criticism from neo-Darwinian theorists but is still a viable hypothesis. Here we present a model, similar to Daisyworld [1] but more general, which allows for a more extensive study of the compatibility of biotic regulation with evolutionary theory. Results obtained highlight the importance of constraints on the evolutionary process for the emergence of regulation, and set the scene for more comprehensive future study. 1

The Evolution of Learning Under Environmental Variability

by Kai Olav Ellefsen
"... An important unanswered question within the evolution of intelligence is how evolved learning efforts relate to environ-mental characteristics. Through simulated evolution of sim-ple learning agents, we study two different models of the relationship between environmental variability and evolved lear ..."

Environmental variability promotes plant invasion

by Madalin Parepa, Markus Fischer, Oliver Bossdorf
"... Global environmental change not only entails changes in mean environmental conditions but also in their variability. Changes in climate variability are often associated with altered disturbance regimes and temporal patterns of resource availability. Here we show that increased variability of soil nu ..."

Environmental variability and the persistence of parasitoid–host metapopulation models

by Andrew D. Taylor - Theor. Popul. Biol , 1998
"... Parasitoidhost metapopulation models (after Reeve) were simulated with varying amounts of spatio-temporal or spatial environmental variability, as well as varying dispersal rates and instability of within-population dynamics. Persistence with environmental variability occurred over broad ranges of l ..."
