Open Source Visual Basic Ecosystem Sciences Software

EcoGeographica is a system that allows field naturalists and scientists to collate and distribute ecological and environmental data, images and files. See www.ecogeographica.net for more details.

The Life Cycle Assessment Spreadsheet allows you to calculate carbon footprints and other environmental impacts for given product systems. Use requires basic skills in LCA and matrix algebra, but rewards effort with professional analytical tools.

PQ Calculator was developed as an easy-to-use and small application that acts as a gene and genotype frequency calculator according to Hardy Weinberg Law fro Ecology. All you have to do is input all the required variables and press the Calculate button, the software will do the rest.

RealMeteo is a custom automatic browser that display automatically satellite weather pictures and webcams. RealMeteo build a meteo point with a single pc connected to web. Many satellite pictures are available on web, and RealMeteo downloads automatically them at time scheduled, and then displays in a slide show the selected pictures. It is the ideal solution for hotels, business centers, train stations, airports and more. JPG AniGIF PNG support. RealMeteo is freeware for personal and no-profit use. Professional users have to pay fee of 36.60 euros (association membership that is free for no-profit users).

SimAssem is a tool for investigating the performances of species richness estimators across widely ranging assemblages and survey designs. Assemblages are simulated by specifying the: 1) number of species, 2) total abundance of individuals, 3) abundance distribution, 4) spatial configuration, 5) species detection probabilities, 6) survey design, and 7) number of grid cells to survey (out of a square grid comprised of 10,000 cells). SimAssem also processes existing encounter data and formats existing and simulated encounter data for other programs. SimAssem, along with the open source code, will hopefully give researchers and managers a tool for assessing the development of new estimators and evaluating potential decisions in a simulated environment. More information on SimAssem is given in Chapter 2, 'SimAssem: a program for simulating species assemblages and estimating species richness', in the dissertation 'Simulating species assemblages and evaluating species richness estimators'.
