For years, the comprehension of the tumor growth process has been intriguing scientists.
New research has been constantly required to better understand the complexity of this …

For this research, the properties of the logistic growth model for independent and coexisting
species were used to set definitions for the possible regulation of one or two growth …

We propose some models of single species with Allee effect based on physical principles. A
method is used to obtain the expression for the per capita growth rate (a macroscopic …

Many physical, biological, and social systems exhibit emergent properties arising from their
components' interactions (cells). In this study, we systematically treat every-pair interactions …

In this work, some phenomenological growth models based only on the population
information (macroscopic level) are deduced in an intuitive way. These models, for instance …

This paper is an extension of a previous work which proposes a non-phenomenological
model of population growth that is based on the interactions among the individuals of a …

The extension of Boltzmann-Gibbs thermostatistics, proposed by Tsallis, introduces an
additional parameter q to the inverse temperature β. Here, we show that a previously …

In this work, a one dimensional population growth model is proposed. The model, based on
the cooperative and competitive individual–individual distance-dependent interaction …

The two-species population dynamics model is the simplest paradigm of inter-and intra-
species interaction. Here, we present a generalized Lotka–Volterra model with intraspecific …

Discarded plastic is subjected to weather effects from different ecosystems and becomes
microplastic particles. Due to their small size, they have spread across the planet. Their …
