Herbicide resistance prediction: a mechanistic model vs a random forest model
Julius-Kühn-Archiv, 2022 Herbicide Resistance is a major issue in weed control. Prediction tools can help to detect herbicide resistance development in early stages and enable farmers to take countermeasures. These tools can be simulation models combining population dynamics and

SPATIAL POPULATION DYNAMICS [PDF]
Papers in Regional Science, 1976 This paper examines the relationships between natural increase (births minus deaths) and net migration (in-migrants minus out-migrants) in regional populations and identifies and clarifies some of the fundamental population dynamics involved. First the authors consider several well-defined regularities of fertility mortality and migration schedules ...

Extinction in population dynamics [PDF]
Physical Review E, 2004 We study a generic reaction-diffusion model for single-species population dynamics that includes reproduction, death, and competition. The population is assumed to be confined in a refuge beyond which conditions are so harsh that they lead to certain extinction.
