Adaptive dynamics is a widely used framework for modeling long-term evolution of continuous phenotypes. It is based on invasion fitness functions, which determine selection gradients and the canonical...
Stable trimorphic coexistence in a lattice model of spatial competition with two site types
Stable trimorphic coexistence；lattice model
2011/1/5
I examine the effect of exogenous spatial heterogeneity on the coexistence of competing species using a simple model of non-hierarchical competition for site occupancy on a lattice. The sites on the l...
The struggle for space: Viral extinction through competition for cells
Viral extinction competition
2011/1/5
The design of protocols to suppress the propagation of viral infections is an enduring enterprise, especially hindered by limited knowledge of the mechanisms through which extinction of infection prop...
Competition, coexistence, and critical behaviour in a lattice tumor-growth model
Competition coexistence critical behaviour lattice tumor-growth model
2010/11/15
In the present paper we study a lattice tumor-growth model. Monte Carlo simulations for $d=$1, 2, and 3 show that when nutrients are easily available, normal and tumor cells coexist. However, when the...
Interference Competition between Rails and Crakes (Rallidae) during Foraging in the Post-Breeding Season
Rallidae Water Rail Rallus aquaticus Crake Porzana interaction aggressive behavior
2010/3/26
In an old riverbed of the Tigris River near the city of Diyarbakir (SE Turkey), observations of foraging Rallidae were made in October 2004. Reciprocal reactions (aggression, mutual foraging) were not...
