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.
For processing and/or simulating species assemblage data.
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'.
BlueM is a software package for river basin management. It allows for the integrated simulation of discharge and pollution loads in rural and urban catchments, including processes in the water body, using physically-based hydrologic approaches.
Caladeros is an easy-to-use program for simulating fisheries behaviour based on FishBanks game (by Dennis Meadows, 1992). It is a role based game on with you can use three different population dynamics models and manage economic parameters in several way
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.
Gene and Genotype frequency Calculator
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.
