A persistence and extinction theory is developed through analytical studies of deterministic
population models. Under hypotheses that require demographic parameters to fluctuate …

A mathematical model of the life-cycle of Echinococcus granulosus in dogs and sheep in
New Zealand is constructed and used to discuss previously published experimental and …

The productivity of marine nematodes was studied from laboratory experiments investigating
the relationship between minimum generation time and temperature, the daily birth rate as …

Some of the results in the literature on simple one-dimensional, density-dependent, discrete
and continuous models—with and without harvesting—are reviewed. Both deterministic and …

In population models the basic unit is the individual. Therefore it is the task of the model
builder to translate his/her knowledge about mechanisms on the individual level into models …

In the use of age structured population models for agricultural applications such as the
modeling of crop-pest interactions it is often essential that the model take into account the …

This chapter is intended as an introduction to the biological questions, mathematical
analyses, and biological conclusions of stochastic models for multispecies assemblages …

Not very long ago, two rash authors wrote that “although age-structure effects frequently
influence the quantitative aspects of population dynamics, they are rather seldom …

A survey is presented of stochastic and deterministic developments in the study of the effects
of nearest-neighbour 'migration'between spatially separated 'colonies'. Such processes are …

Mathematical models are developed in order to analyze whether or not social factors, such
as, for example, the “social fence”(JB Hestbeck, 1982, Oikos 39, 157–163) will stabilize …
