Competing associations in six-species predator-prey models
We study a set of six-species ecological models where each species has two predators and two prey. On a square lattice the time evolution is governed by iterated invasions between the neighboring predator-prey pairs chosen at random and by a site exchange with a probability Xs between the neutral pairs. These models involve the possibility of spontaneous formation of different defensive allianc...
متن کاملSelf-organizing patterns maintained by competing associations in a six-species predator-prey model.
Formation and competition of associations are studied in a six-species ecological model where each species has two predators and two prey. Each site of a square lattice is occupied by an individual belonging to one of the six species. The evolution of the spatial distribution of species is governed by iterated invasions between the neighboring predator-prey pairs with species specific rates and...
متن کاملCoexistence in competing species models, I: the Neuhauser-Pacala model
This is a concise version of the lecture note for the first part of the learning session “Competing species models” held on 3rd August 2017 at the National University of Singapore1. This part is centered around the Neuhauser-Pacala model [3] in terms of methods of “Bernoulli subsystems” in [1, 4]. The second part of the session is led by Matthias Hammer and discusses related models of interacti...
متن کاملStochastic models for competing species with a shared pathogen.
The presence of a pathogen among multiple competing species has important ecological implications. For example, a pathogen may change the competitive outcome, resulting in replacement of a native species by a non-native species. Alternately, if a pathogen becomes established, there may be a drastic reduction in species numbers. Stochastic variability in the birth, death and pathogen transmissio...
متن کاملWhich Models Are Appropriate for Six Subtropical Forests: Species-Area and Species-Abundance Models
The species-area relationship is one of the most important topic in the study of species diversity, conservation biology and landscape ecology. The species-area relationship curves describe the increase of species number with increasing area, and have been modeled by various equations. In this paper, we used detailed data from six 1-ha subtropical forest communities to fit three species-area re...
