Mechanisms leading to bursting oscillations in the system of predator–prey communities coupled by migrations [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика, 2023
The purpose is to study the periodic regimes of the dynamics for two non-identical predator–prey communities coupled by migrations, associated with the partial synchronization of fluctuations in the abundance of communities.

Simple and complex dynamics in the model of evolution of two populations coupled by migration with non-overlapping generations [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика, 2022
Purpose is to study the mechanisms leading to genetic divergence (stable genetic differences between two adjacent populations). We considered the following classical model situation. Populations are panmictic with Mendelian rules of inheritance.

Clustering Synchronization in a Model of the 2D Spatio-Temporal Dynamics of an Age-Structured Population with Long-Range Interactions

open access: yesMathematics, 2023
The inhomogeneous population distribution appears as various population densities or different types of dynamics in distant sites of the extended habitat and may arise due to, for example, the resettlement features, the internal population structure, and

Transition from Bi- to Quadro-Stability in Models of Population Dynamics and Evolution

open access: yesMathematics, 2023
The article is devoted to a review of bistability and quadro-stability phenomena found in a certain class of mathematical models of population numbers and allele frequency dynamics. The purpose is to generalize the results of studying the transition from

On the genetic divergence of two adjacent populations living in a homogeneous habitat [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика, 2021
The purpose is to study the mechanisms leading to the genetic divergence, i.e. stable genetic differences between two adjacent populations coupled by migration of individuals.

Approaches to study of multistability in spatio-temporal dynamics of two-age population [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика, 2020
Purpose of the work is to study spatio-temporal dynamics of limited two-age structured populations that populate a 2D habitat and capable of long-range displacement of individuals. We proposed the model that is the network of nonlocally coupled nonlinear

INFORMATION-ANALYTICAL SYSTEM OF FORECAST VEGETATION FIRES IN NATURAL CONDITIONS

open access: yesInterCarto. InterGIS, 2015
A system for spatial prediction for fire danger as function of weather and pyrological vegetation characteristics was constructed. The method of calculating the time conducted vegetable combustible materials in fire condition of each month of the season ...
