Predicting seasonal dynamics of UK mosquito vectors across urban and rural gradients
Understanding how urban and rural gradients alter mosquito temporal abundance in a way that is likely to cause outbreaks of mosquito-borne disease (e.g. West Nile virus) is central to predicting the impact and management of diseases. Environmental drivers (such as rainfall, temperature, evaporation, competition and predation) that vary along urban to rural gradients, affect development, fecundity, survival and therefore abundance of mosquitoes. Spatial variability in environmental drivers also affects abundance and phenology of wildlife and human hosts upon which the mosquitoes feed. Whilst spatial and land use gradients have direct effects on pathogen transmission rates, perhaps the most subtle and profound impacts are on vector species phenology and interactions with susceptible hosts. The temporal pattern of female-blood feeding mosquito abundance in relation to the availability of susceptible hosts is a key determinant of whether a mosquito-borne disease can establish and persist in wildlife, humans and domestic animals. The aim of this project is to investigate the role of urban and rural gradients in driving seasonal and spatial variability in mosquito populations and overlap with hosts. The student will develop and analyse a system of state-dependent delayed differential equations in which environmental drivers affect life-history parameters and development lags focusing on UK mosquito species such as Culex pipiens and Culiseta annulata, which are potential vectors of disease. The model will be analysed by extensive mathematical and numerical simulation techniques using a suitable programming language on high performance computing clusters. In addition, the student will validate the models against new and existing temporal datasets using a broad range of statistical techniques. Finally, the student will derive and analyse a mosquito community model to investigate how host availability shapes the likelihood of disease across urban and rural gradients controlling for competition between mosquito species, predation and abiotic drivers. Overall, the research will demonstrate the value of predictive models that help to understand the dynamics of mosquitoes and mosquito-borne diseases. Further reading: Townroe S, Callaghan A.

Mathematical modelling of mosquito population dynamics. DDE model simulation using solver algorithms on a high performance computer cluster. Using statistical modelling to fit mathematical models to data.
The student will develop novel mathematical models for predicting mosquito abundance. Unlike most mechanistic models, the student will validate their models against large ecological datasets.
The project will develop ecological theory for the population dynamics of mosquito populations, in particular understand how environmental gradients shape patterns of abundance.
Management of mosquito populations is difficult to deliver, this is in part due to not fully understanding the drivers of dynamics and patterns of abundance. This project aims to reduce this uncertainty and therefore aid control strategies.
Correlative approaches are mainly used to investigate seasonal patterns of temperate mosquito abundance, thus limiting their use to the training dataset. As such, correlative approaches fail to understand the underlying mechanisms. The project will set new standards by delivering novel mechanistic models, underpinned by data, which are inherently more useful for scenario testing.
This project marries together mathematical and statistical modelling, big data, epidemiology and mosquito biology.
