Diversity Description

Simple data entry and analysis for ecology Diversity is a new tool for entering and inspecting ecological data, and for measuring the diversity of ecological communities. Spreadsheets have long been the standard tool for ecological data entry, but spreadsheets are cumbersome for working with these data. Diversity makes it quick to enter your data and to see the composition of your samples. With Diversity all the standard measures of diversity, including both sample-based and individual-based rarefaction, are made blazingly fast. Here are some key features of "Diversity": · Easy to use - Use spreadsheets for number crunching, not for data entry and viewing! Watch Diversity in action. · Fast data entry - Data entry in Diversity is quick. Type a few characters for the species name, and enter the abundance. No scrolling back and forth through a spreadsheet and no more entering zeroes for species that don't occur. Easier data entry means fewer errors. · Easy sample viewing - Easily see the composition of any sample. Sort the samples by species name or abundance. Quickly step through any or all of your samples. · Import your existing data - Diversity can import from standard CSV (comma-delimited) files. Import one collection or an entire set of collections in one step. Even import a simple list of abundances for quick analysis. Watch how easy it is to import your data. · Export your data for other programs - Diversity works well with all of your data analysis software. Export your data in standard CSV formats that can be readily by other statistical packages, including R. Watch how easy it is to export your data. · Common diversity metrics - Diversity instantly calculates common metrics of richness and evenness, including Shannon's H, Pielou's J, Simpson's D, and Peters' Ess. Diversity also computes diversity extrapolations, including the Chao-1 and Chao-2 estimators. · Individual-based and sample-based rarefaction - Use rarefaction to estimate the diversity in your samples and all of your data at smaller samples. Diversity uses a fast analytical technique for calculating both individual-based and sample-based rarefaction. Diversity generates customizable publication-ready rarefaction plots. You can also export the rarefaction results to make more complex figures in most graphics programs. Limitations: · 30 days trial period.
