Detecting and modelling delayed density-dependence in abundance time series of a small mammal (Didelphis aurita)
E. Brigatti, M. V. Vieira, M. Kajin +3
We study the population size time series of a Neotropical small mammal with the intent of detecting and modelling population regulation processes generated by density-dependent fac…
Analysis of a spatial Lotka-Volterra model with a finite range predator-prey interaction
E. Brigatti, M. Núñez-López, M. Oliva
We perform an analysis of a recent spatial version of the classical Lotka-Volterra model, where a finite scale controls individuals' interaction. We study the behavior of the preda…
Pattern formation in a predator-prey system characterized by a spatial scale of interaction
E. Brigatti, M. Oliva, M. Núñez-López +2
We describe pattern formation in ecological systems using a version of the classical Lotka-Volterra model characterized by a spatial scale which controls the predator-prey interact…
Speciational view of macroevolution: are micro and macroevolution decoupled?
V. Schwammle, E. Brigatti
We introduce a simple computational model that, with a microscopic dynamics driven by natural selection and mutation alone, allows the description of true speciation events. A stat…
Evolution of polymorphism and sympatric speciation through competition in a unimodal distribution of resources
E. Brigatti, J. S. Sa' Martins, I. Roditi
A microscopic agent dynamical model for diploid age-structured populations is used to study evolution of polymorphism and sympatric speciation. The underlying ecology is represente…
Sharp gene pool transition in a population affected by phenotype-based selective hunting
E. Brigatti, J. S. Sa' Martins, I. Roditi
We use a microscopic model of population dynamics, a modified version of the well known Penna model, to study some aspects of microevolution. This research is motivated by recent r…
