Simulating SEMs for piecewiseSEM: part 1 the basics

Structural Equation Models are being used more and more frequently by ecologists due to the appeal of linking variables together in complex web of interactions. There are currently two main libraries in R to fit such models: lavaan and piecewiseSEM. The aim of this post is not to discuss the advantages and drawbacks of these … Continue reading Simulating SEMs for piecewiseSEM: part 1 the basics

Spatial Dynamic in a Host-Parasitoid system

In this post I will explore the spatial dynamic that arise from a simple deterministic host-parasitoid model with migration in a homogeneous environment. If the previous sentence did not drive you away, congrats (!) you are most certainly in a terminal state towards biological nerditude. The idea of this post emerged while reading Chp. 6 … Continue reading Spatial Dynamic in a Host-Parasitoid system
