Visualizing basic biodiversity pattern across spatial scales

BiodiViz -- Visualizing biodiversity patterns across spatial scales

Authors

Katharina Gerstner, Petr Keil

Description

This is an interactive tool that aims to visualize multiple biodiversity patterns at multiple spatial scales. The tool (1) simulates locations of individuals of different species in a location (plot, area); the key parameters of the simulation are total number of individuals, total number of species, eveness of the abundances and aggregation of species.
(2) plots biodiversity patterns such as species-abundance distributions (SAD), species accummulation curves (SAC), species-area relationships (SAR) and alike for a selected grid cell and for the entire region.

The package that is used to simulate the community is Felix May's mobsim. We use Thomas model to simulate point pattern distributions of individual species.

The interactive interface relies on package manipulate.
