Climate change is having a profound effect on biotic and abiotic drivers of disease spread. However, predicting how individual diseases respond to climate change is challenging to predict and requires new predictive frameworks. For mosquito-borne diseases, where mosquito life-stages occupy different niches, drivers may affect components of the pathosystem in complex and opposing ways. For example, changes in the patterns of seasonal rainfall and temperature, can affect variable life-history traits such as development, survival, fecundity and disease transmission. These traits may combine to give rise to sharp changes of species abundance and transmission dynamics, especially under climate change extremes, which impacts on our ability to predict mosquito population dynamics and the likelihood of disease outbreaks and subsequent impact of mitigation measures.The aim of this project is to investigate the role of climate change in driving seasonal variability in mosquito populations and their diseases. The student will develop and analyse a system of state-dependent delayed differential equations in which environmental drivers affect life-history traits. The model will be analysed by extensive mathematical and numerical simulation techniques using a suitable programming language. The student will extend the mosquito model to include disease transmission to investigate how climate change will shape the likelihood of disease outbreaks in future climates. In addition, the student will validate the models against new and existing trait and spatial-temporal datasets provided by the VectorBite Research Coordination Network.

气候变化对疾病扩散的生物和非生物驱动因素产生了深远的影响。但是，预测单个疾病如何应对气候变化是一项挑战，需要预测并需要新的预测框架。对于蚊子生命阶段占据不同的壁ni的蚊子传播疾病，驾驶员可能会以复杂和相反的方式影响病态系统的组成部分。例如，季节性降雨和温度模式的变化会影响可变的生活历史特征，例如发育，生存，繁殖力和疾病传播。这些特征可能会结合起来，引起物种丰度和传播动态的急剧变化，尤其是在气候变化极端的情况下，这影响了我们预测蚊子人口动态的能力以及疾病爆发的可能性以及缓解措施的后续影响。该项目的目的是调查气候变化在驱动季节性变化中的作用在蚊子群体中的作用及其在蚊子群体中的作用及其疾病及其疾病的作用。该学生将开发和分析一个依赖状态的延迟差分方程的系统，在这种方程式中，环境驱动力会影响生活历史特征。该模型将使用合适的编程语言通过广泛的数学和数值模拟技术进行分析。该学生将扩展蚊子模型，包括疾病传播，以调查气候变化如何影响未来气候中疾病爆发的可能性。此外，学生将验证这些模型，以抵御VectorBite研究协调网络提供的新的和现有的特征和时空数据集。
