The role of behavioral dynamics in determining the patch distributions of interacting species
Original language description
The effect of the behavioral dynamics of movement on the population dynamics of interacting species in multipatch systems is studied. The behavioral dynamics of habitat choice used in a range of previous models are reviewed. There is very limited empirical evidence for distinguishing between these different models, but they differ in important ways, and many lack properties that would guarantee stability of an ideal free distribution in a single-species system. The importance of finding out more about movement dynamics in multispecies systems is shown by an analysis of the effect of movement rules on the dynamics of a particular two-species?two-patch model of competition, where the population dynamical equilibrium in the absence of movement is often not a behavioral equilibrium in the presence of adaptive movement. The population dynamics of this system are explored for several different movement rules and different parameter values, producing a variety of outcomes.

Dynamika prostorového rozložení interagujících populací
Czech description
Článek analyzuje modely dvou kompetujících si populací v heterogenním prostředí skládajícím se ze dvou potravních nik. Analýza ukazuje, že pokud se organismy chovají adaptivně, tj. zdržují se v nice ve které se maximalizuje jejich fitness, pak taková adaptivní strategie může destabilizovat jejich populační dynamiku a vést k vyhynutí jedné z populací.
