Jacqueline et al., You might check out DIVA-GIS (http://www.diva-gis.org/). It's designed for biodiversity/ecology applications. I don't know that it supports the specific excercise you describe below, but you and the other ecologgers mind find it useful, particularly in the teaching environment. And it's FREE! Good luck, Phil Morefield

To: [email protected] Date: Thursday, February 5, 2009, 7:56 AM Dear Ecologger I'm looking for a free and easy to use software to use in my ecology course. For one lab exercice, my students have to fill in cohort tables (survivorship, mortality, fecundity etc.) to draw different survivorship curves. To make this exercice more interesting and applied, I'd like to find a program that would allow the students to enter this data and get a graph back, that shows them the popultation increas/decrease over the next 100-200 years. With this program they could play with the data and see what implications different management decisions (ie protecting early life stage vs. late life stages) would have for this population. Does anyone know of such a free/shareware? I appreciate your help.
