ABSTRACTA promising strategy for reducing the transmission of dengue and other arboviral human diseases byAedes aegyptimosquito vector populations involves field introductions of the endosymbiotic bacteriaWolbachia.Wolbachiainfections inhibit viral transmission by the mosquito, and can spread between mosquito hosts to reach high frequencies in the vector population.Wolbachiaspreads by maternal transmission, and spread dynamics can be variable and highly dependent on natural mosquito population dynamics, population structure and fitness components.We develop a mathematical model of anAe. aegyptimetapopulation that incorporates empirically validated relationships describing density-dependent mosquito fitness components. We assume that density dependence relationships differ across subpopulations, and construct heterogeneous landscapes for which model-predicted patterns of variation in mosquito abundance and demography approximate those observed in field populations. We then simulateWolbachiarelease strategies similar to that used in field trials.We show that our model can produce rates of spatial spread ofWolbachiasimilar to those observed following field releases.We then investigate how different types of spatio-temporal variation in mosquito habitat, as well as different fitness costs incurred byWolbachiaon the mosquito host, influence predicted spread rates. We find that fitness costs reduce spread rates more strongly when the habitat landscape varies temporally due to stochastic and seasonal processes.Our empirically based modelling approach represents effects of environmental heterogeneity on the spatial spread ofWolbachia.The models can assist in interpreting observed spread patterns following field releases and in designing suitable release strategies for targeting spatially heterogeneous vector populations.

This article explores the spatial dynamics of agrofuels. Building on categories from the field of critical spatial theory, it shows how these categories enable a comprehensive analysis of the spatial dynamics of agrofuels that links the macro-structures of the global political economy to concrete, place-based struggles. Four core socio-spatial dynamics of agrofuel politics are highlighted and applied to empirical findings: territorialization, the financial sector as a new scale of regulation, place-based struggles and transnational spaces of resources and capital flows.
