Diversity waves in collapse-driven population dynamics [PDF]
, 2015 Populations of species in ecosystems are often constrained by availability of resources within their environment. In effect this means that a growth of one population, needs to be balanced by comparable reduction in populations of others.

Competitive Lotka-Volterra Population Dynamics with Jumps [PDF]
, 2011 This paper considers competitive Lotka-Volterra population dynamics with jumps. The contributions of this paper are as follows. (a) We show stochastic differential equation (SDE) with jumps associated with the model has a unique global positive solution;

Predators reduce extinction risk in noisy metapopulations [PDF]
, 2010 Background Spatial structure across fragmented landscapes can enhance regional population persistence by promoting local “rescue effects.” In small, vulnerable populations, where chance or random events between individuals may have disproportionately ...

Population dynamics at high Reynolds number [PDF]
, 2010 We study the statistical properties of population dynamics evolving in a realistic two-dimensional compressible turbulent velocity field. We show that the interplay between turbulent dynamics and population growth and saturation leads to quasi ...

Why Do Herbivorous Mites Suppress Plant Defenses?
Frontiers in Plant Science, 2018 Plants have evolved numerous defensive traits that enable them to resist herbivores. In turn, this resistance has selected for herbivores that can cope with defenses by either avoiding, resisting or suppressing them. Several species of herbivorous mites,

Tetranychus evansi spider mite populations suppress tomato defenses to varying degrees
Ecology and Evolution, 2020 Plant defense suppression is an offensive strategy of herbivores, in which they manipulate plant physiological processes to increase their performance. Paradoxically, defense suppression does not always benefit the defense‐suppressing herbivores, because

Stochastic gain in population dynamics
, 2004 We introduce an extension of the usual replicator dynamics to adaptive learning rates. We show that a population with a dynamic learning rate can gain an increased average payoff in transient phases and can also exploit external noise, leading the system

Myopic Models of Population Dynamics on Infinite Networks [PDF]
, 2013 Reaction-diffusion equations are treated on infinite networks using semigroup methods. To blend high fidelity local analysis with coarse remote modeling, initial data and solutions come from a uniformly closed algebra generated by functions which are ...

Resource Allocation with Population Dynamics
, 2016 Many analyses of resource-allocation problems employ simplistic models of the population. Using the example of a resource-allocation problem of Marecek et al.

Population Dynamics of Rhizobacteria and Its Potency as a Biological Control Agent to Control Fusarium Disease in the Nursery of Agarwood (Aquailaria Malaccensis Lamrk) [PDF]
, 2015 Agarwood is a resin product produced by particular trees and has a certain high comercial value. In Central Bangka Regency, agarwood is the main commodity of forest.
