R code

The database contains variable information for Indian alien flora. The R scripts written to analyze the data and to plot the results have been placed in this repository: 

• To compute descriptive statistics

• Imputation of missing data

• Logistic regression

• Path analysis

• Plotting data availability

• Plotting growth forms for invasion categories

• Plotting introduction pathways

• Plotting number of landscape classes for invasion categories

• Plotting market dynamics

The codes for analyzing the molecular biology data and plotting the results have been placed in this repository. The repository now contains the following: 

• Bayesian Phylogeographic and Ecological Clustering

• Discriminant Analysis of Principal Components

• Nonlinear relationship between genetic differentiation and geographic distances [isolation by distance, environment, and resistance]

• The standardized measure of genetic differentiation

• Analysis of genetic structure using Geneland

• Phylogenetic tree and analysis of phylogenetic signals for plant traits

• Plotting genetic structure

The codes for modeling species distribution have been placed in this repository. The repository now contains the following:

• Downloading bioclimatic variables, processing occurrence, and climate data, selection of variables

• Niche characterization

• Testing of model transferability

• Modeling distribution of an invasive species

• Modeling distribution of a true mangrove species

• Downloading occurrence data for a large number of species from GBIF
