File Description

Purpose of the program
Spatial and temporal-explicit simulation of seed dispersal by wind.

Main ecological features simulated
This model simulates the dispersal of individual seeds from trees to a flat surface taking into account plant and meteorological characteristics described in the paper. Default parameter values in this version are those estimated for Aleppo pine (Pinus halepensis Mill.) in the study site on Mt. Carmel, Israel (called NE in the paper). The spatial resolution is 1 m^2 and the temporal resolution - one day or more, depending on the length of the period(s) considered (in which meteorological data are available).

Required hardware
Either a Pentium PC or Unix operating system (providing a proper data file format).

Required software
A C compiler and a C-language random number generator (uniform and normal random number generator).

Installation and operation
Copy windis10.exe to a new directory, and extract the files (double-click on windis10.exe). Add a program with uniform and normal random number generators, under the name rand.c (see header file rand.h). Complile a C project with all C files (windis10.c, getdata.c, parse.c, and your rand.c). When running the program, all input and output files are assumed to be in the same directory.
