Explore computational methods for simulating and analyzing ecological systems in this lecture from the Serrapilheira/ICTP-SAIFR Training Program in Quantitative Ecology. Delve into topics such as population density, numerical errors, and numerical solutions as presented by Renato Coutinho from UFABC. Learn about population dynamics, time-dependent processes, aging effects, and diffusion models in ecological contexts. Gain insights into how computational approaches can be applied to address general questions in ecology and enhance understanding of complex ecological phenomena.
