A General Discrete Time Model of Population Dynamics in the Presence of an Infection [PDF]
Discrete Dynamics in Nature and Society, 2009 We present a set of difference equations which generalizes that proposed in the work of G. Izzo and A. Vecchio (2007) and represents the discrete counterpart of a larger class of continuous model concerning the dynamics of an infection in an organism or ...

A general modeling framework for describing spatially structured population dynamics [PDF]
Ecology and Evolution, 2018 Variation in movement across time and space fundamentally shapes the abundance and distribution of populations. Although a variety of approaches model structured population dynamics, they are limited to specific types of spatially structured populations ...

Positive global solutions for a general model of size-dependent population dynamics [PDF]
Abstract and Applied Analysis, 2000 We study size-structured population models of general type which have the growth rate depending on the size and time. The local existence and uniqueness of the solution have been shown by Kato and Torikata (1997).

Exercise-Induced Blood Pressure Dynamics: Insights from the General Population and the Athletic Cohort [PDF]
Journal of Cardiovascular Development and Disease, 2023 Blood pressure (BP) dynamics during graded exercise testing provide important insights into cardiovascular health, particularly in athletes. These measurements, taken during intense physical exertion, complement and often enhance our understanding beyond

A General Model of Population Dynamics Accounting for Multiple Kinds of Interaction [PDF]
Complexity, 2020 Population dynamics has been modelled using differential equations almost since Malthus times, more than two centuries ago. Basic ingredients of population dynamics models are typically a growth rate, a saturation term in the form of Verhulst’s logistic ...

Local existence for a general model of size-dependent population dynamics
Abstract and Applied Analysis, 1997 We shall investigate a size structured population dynamics with aging and birth functions having general forms. The growth rate we deal with depends not only on the size but also on time.

Dynamics of General Class of Difference Equations and Population Model with Two Age Classes [PDF]
Mathematics, 2020 In this paper, we study the qualitative behavior of solutions for a general class of difference equations. The criteria of local and global stability, boundedness and periodicity character (with period 2 k ) of the solution are established ...

Journal of Integrative Agriculture, 2013 A 2-yr field study was conducted to assess the effects of transgenic japonica rice (KMD1 and KMD2) with a synthetic cry1Ab gene from Bacillus thuingiensis Berliner on population dynamics and seasonal average densities of five thrips species including ...

Scientific Reports, 2017 Interspecific mating interactions, or reproductive interference, can affect population dynamics, species distribution and abundance. Previous population dynamics models have assumed that the impact of frequency-dependent reproductive interference depends
