Effects of rainfall on Culex mosquito population dynamics [PDF]

Journal of Theoretical Biology, 2017
The dynamics of a mosquito population depends heavily on climatic variables such as temperature and precipitation. Since climate change models predict that global warming will impact on the frequency and intensity of rainfall, it is important to understand how these variables affect the mosquito populations. We present a model of the dynamics of a {\it

Extreme rainfall reduces one-twelfth of China’s rice yield over the last two decades

Nature Food, 2023
Extreme climate events constitute a major risk to global food production. Among these, extreme rainfall is often dismissed from historical analyses and future projections, the impacts and mechanisms of which remain poorly understood.
