Effects of Plant Density and Diversity on the Population Dynamics of a Specialist Herbivore, the Striped Cucumber Beetle, Acalymma Vittata (Fab)
TL;DR: To determine the effects of plant density and diversity on the population dynamics of a specialist herbivore, the striped cucumber beetle, cucumbers, and its insect predators were planted in monocultures and in polycultures with corn and broccoli.

The Evolutionary Potential of Lacandon Maya Sustained-Yield Tropical Forest Agriculture
James D. Nations,Ronald Nigh +1 more
TL;DR: In this article, the authors describe the Lacandon systems of agricultural production, wildlife management, and forest maintenance, and explore the potential these strategies hold for investigation of ancient Maya food production systems and the development of modern resource utilization schemes in the humid tropics.
Journal ArticleDOI
The population dynamics of competition between parasites.
TL;DR: It is suggested that two general levels of interaction are discernible: these correspond to the two levels of competition recognized by workers studying free-living animals and plants: 'exploitation' and 'interference' competition.

Fluctuations in density of an outbreak species drive diversity cascades in food webs
Eldon S. Eveleigh,Kevin S. McCann,Peter C. McCarthy,Steven J. Pollock,Christopher J. Lucarotti,Christopher J. Lucarotti,Benoit Morin,George A. McDougall,D.B. Strongman,John T. Huber,James Umbanhowar,Lucas Del Bianco Faria +11 more
TL;DR: It is shown that a complex web of interactions between insect herbivores and their natural enemies displays significant architectural flexibility over a large fluctuation in the natural abundance of the major herbivore, the spruce budworm, and it is found that this food-web flexibility tends to be greater in heterogeneous than in homogeneous forest plots.

A stochastic SIRS epidemic model with nonlinear incidence rate
Yongli Cai,Yun Kang,Weiming Wang +2 more
TL;DR: Investigation of the global dynamics of a general SIRS epidemic model with a ratio-dependent incidence rate and its corresponding stochastic differential equation version finds that random fluctuations introduced in the model can suppress disease outbreak, which can provide some useful control strategies to regulate disease dynamics.
