Metapopulation dynamics and biological invasions: a spatially explicit model applied to a freshwater snail.
The spatial spread of invading organisms is a major contemporary concern. We focus here on invasions in inherently fragmented habitats, such as freshwater systems, and explore the usefulness of metapopulation models in this context. Maximum-likelihood methods allow the estimation of colonization and extinction rates, as functions of habitat patch sizes and positions, from time series of presenc...
متن کاملA demographic, spatially explicit patch occupancy model of metapopulation dynamics and persistence
Patch occupancy models are extremely important and popular tools for understanding the dynamics, and predicting the persistence, of spatially structured populations. Typically this endeavor is facilitated either by models from classic metapopulation theory focused on spatially explicit, dispersal-driven colonization–extinction dynamics and generally assuming perfect detection, or by more recent...
متن کاملANOSPEX: A Stochastic, Spatially Explicit Model for Studying Anopheles Metapopulation Dynamics
Anopheles mosquitoes transmit malaria, a major public health problem among many African countries. One of the most effective methods to control malaria is by controlling the Anopheles mosquito vectors that transmit the parasites. Mathematical models have both predictive and explorative utility to investigate the pros and cons of different malaria control strategies. We have developed a C++ base...
متن کاملSheep Scab Controls
Ovine psoroptic mange or sheep scab (also known by the descriptive names of belt, shab, tag or rubbers) is said to be one of the earliest known ectoparasitic infections. Sheep scab has been known since ancient times. It was known to Moses and has been documented by Cato, Virgil, Pleno and Columnella and (apparently) is referred to in the Bible (Leveticus XXII, 22). Although the Arabs were aware...
متن کاملA spatially structured metapopulation model with patch dynamics.
Metapopulation models that incorporate both spatial and temporal structure are studied in this paper. The existence and stability of equilibria are provided, and an extinction threshold condition is derived which depends on patch dynamics (patch destruction and creation) and metapopulation dynamics (patch colonization and extinction). These results refine threshold conditions given by previous ...
