MEAN-DD.ZIP

Description

MEAN-DD.ZIP is a compressed zip file containing 43 files comprising a software system for pc computers that simulates animal dispersal and calculates mean dispersal distances. The main program is MEAN-DD.EXE which when run will simulate a population of animals dispersing outward from a release point. The menu allows running another program MDD-STEP.EXE which can generate animal paths and segment them into different sized steps to determine how the predicted mean dispersal distance from equations is affected. Both compiled programs can display the text and figures of the paper in Ecology (MEAN-DD.TXT). The figures are contained in 33 files ending in .A12, .B12, and .C12. Each figure requires 3 such files with a parent name, for example, MDDFIG1 for Fig. 1. Other files of figures are MDDFIG2.*, MDDFIGB2.*, MDDFIG3.*, MDDFIG4.*, MDDFIG5.*, MDDFIGB5.*, MDDFIG6.*, MDDFIG7.*, MDDFIG8.*, and MDDFIG9.*. MEAN-DD.PIC and M-PATH.PIC are image files for the titles on the opening screen of each compiled program. MEAN-DD.A12, MEAN-DD.B12, MEAN-DD.C12 and MEAN-DD.P12 comprise the opening and ending screen image of a sunset over lake Fryken in middle Sweden. READVAL.#@! is a file generated by the compiled programs that keeps track of the last place read in the paper.
