We introduce in this paper a new interacting particle system intended to model an example of ecological succession involving two species: Pteridium aquilinum L. commonly called bracken and Fagus sylvatica L. or european beech. The species both compete over vacant sites, assimilated to windfall, according to fundamentally different evolutionary strategies. Our main objective is to exhibit phase ...

The mam plant communities of ultramafic (serpentine) outcrops of a Mediterranean area in central Italy are described and their successional pathway discussed. Four vegetation stages are distinguished: a) an endemic garigue stage, with high percentage of exposed rocky soil belonging to Armerio-Alyssetum bertolonii; b) a garigue stage similar to the previous one but with several Mediterranean eve...

Quantifying the drivers underlying the distribution of biodiversity during succession is a critical issue in ecology and conservation, and also can provide insights into the mechanisms of community assembly. Ninety plots were established in the Loess Plateau region of northern Shaanxi in China. The taxonomic and phylogenetic (alpha and beta) diversity were quantified within six succession stage...

ECO-method and its corresponding succession rules allow to recursively define and construct combinatorial objects. We introduce here succession functions which refine succession rules. They permit to construct general efficient algorithms for classes of combinatorial objects and to find some new classes more easily than previous methods. We apply succession function technique for a lot of class...

Dr. B. T. Galloway, Mr. Charles F. Deering and Professor W. D. Crocker were elected to membership. The program of the evening was devoted to the subject of "The Relation of Plant Succession to Forestry and Grazing." Mr. C. G. Bates discussed the natural regeneration of forest stands in the climax formations of the Rocky Mountain region and called attention especially to the temporary control of...

Current theories about vegetation succession and food web assembly are poorly compatible, as food webs are generally viewed to be static, and succession is usually analyzed without the inclusion of higher trophic levels. In this study we present results from a detailed analysis of ecosystem assembly rules over a chronosequence of 100 years of salt marsh succession. First, using 13 yearlong obse...
