Journal of the American Mosquito Control Association, 2007 This chapter reviews aspects of population dynamics that may be conceptually important for biological control of mosquitoes. Density dependent population regulation among immature stages has important implications for biological control of mosquito populations, primarily because it can lead to compensatory or overcompensatory mortality due to additions

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 ...

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

Estimating population dynamics without population data [PDF]
Journal of Environmental Economics and Management, 2013 Abstract We develop a biologically correct cost system for production systems facing invasive pests that allows the estimation of population dynamics without a priori knowledge of their true values. We apply that model to a data set for olive producers in Crete and derive from it predictions about the underlying population dynamics.
