Generating random landscapes

A little bit of information on generating random landscapes with specified spatial autocorrelation

Plant photos from Henry Horn

Some images of forests and other plant communities taken by Henry Horn and slide-scanned by me for some talks I was giving. Check 'em out.

Measles and other disease data

Time-series and auxiliary data on measles and chickenpox in England and Wales, New York, Copenhagen, Baltimore ... What you see is what you get.

Input files for spatial moment equations in xtc

These are input files that define various types of spatial, stochastic single-species plant competition equations (analogous to logistic growth). They work with the program xtc, which numerically integrates one-dimensional partial- and integro-differential equations, and which you can get (free) from Bard Ermentrout (it runs on various Unix/X11 platforms). (See my various manuscripts on the subject for more info about the models themselves.)
