Ecological Niche Models

11.06.2024

Introduction Ecological niche modeling (ENM) is a method used to predict the distribution of species based on environmental conditions and species occurrence data. In this code, we will create ecological niche models using R, focusing on two species: Peromyscus maniculatus and Hantavirus. We will use the ellipsenm package to construct our mode...

Eliminating Multicollinearlity

11.06.2024

Introduction Multicollinearity occurs when predictor variables in a regression model are highly correlated, leading to unreliable estimates of regression coefficients and difficulties in determining the individual effect of each predictor. In ecological niche modeling, multicollinearity among environmental variables can distort model predictio...

Spatial Thinning of Species Occurrence Records

11.06.2024

Introduction Spatial thinning is a process used to reduce the spatial autocorrelation of species occurrence data. This is important to avoid overfitting in ecological niche models and to ensure the models are more reliable. This document demonstrates how to thin occurrence records for Peromyscus maniculatus and Hantavirus using R. Load and Ins...
