EstimateS

EstimateS is a free software application for Windows and Macintosh operating systems that computes a variety of biodiversity statistics, estimators, and indices based on biotic sampling data. Some features require species relative abundance data, others only species presence/absence data. A  comprehensive User's Guide is available online at this site.

Major Features of EstimateS 9

Nonparametric rarefaction and extrapolation of species accumulation curves

• Computes expected species accumulation curves for rarefied reference samples (both sample-based rarefaction curves and individual-based rarefaction curves, in the terminology of Gotelli & Colwell 2001, 2011), with 95% unconditional confidence intervals, using the analytical formulas of Colwell et al. (2004) and Colwell et al. (2012). 
• Computes expected species accumulation curves for augmented reference samples (both sample-based extrapolation curves and individual-based extrapolation curves), with 95% unconditional confidence intervals, using the analytical formulas of Colwell et al. (2012). 

Species richness estimators and diversity indices

• Computes non-parametric, asymptotic species richness estimators for abundance-based data (Chao 1 and ACE) and for incidence-based data (Chao2, ICE, first and second order Jackknives, and Bootstrap).
• For Chao1 and Chao 2, computes log-linear confidence intervals.
• Computes Shannon (both H and e^H) and inverse Simpson (Hill numbers 1 and 2), and Fisher's alpha diversity indices.
• All estimators and indices are computed for rarefied samples or individuals to reduce the bias of comparisons.

Shared species estimation and biotic similarity indices, with estimators

• Computes Chao's estimator of total shared species (including observed and unseen shared species) for sample pairs.
• Computes classic Sørensen and Jaccard similarity indices for sample pairs based on incidence (presence-absence) or abundance data sets
• Computes Chao's abundance-based Sørensen and Jaccard similarity indices, with statisically rigorous estimators and their standard errors, for sample pairs based on abundance or on replicated incidence (presence-absence) data sets.
• Computes Morisita-Horn and Bray-Curtis (= "Sørensen quantitative") similarity indices for sample pairs based on abundance data sets.

Importing data and exporting results

• For input, accepts tab-delimited, plain text files (produced by programs such as Excel, using "Save As Tab-delimited Text"), in either of two matrix formats (species-by-sample or , sample-by-species) or either of two "triplet" formats ([species index, sample index, value]; or [sample index, species index, value]).
• For input, accepts pre-formatted sample-by-species matrices exported by Biota: The Biodiversity Database Manager.
• Exports all results as tab-delimited text files, easily opened in Excel, statistical, or graphing applications.
• As an option, records and exports results from n individual randomizations to a text file, allowing computation of precision, accuracy, and other analyses (Walther and Moore 2005), using Excel or other applications.

SPADE

The Program SPADE (Species Prediction And Diversity Estimation), written in C language, estimates various biodiversity indices based on different types of sample data from one or multiple communities. It is a free software, and this user guide attempts to explain how to use this program in an easily accessible way using numerical examples and explanations. The program is divided into seven parts: 

Part I: Species (estimating species richness for one community based on the observed species frequencies or presence/absence data) 

Part II: Shared Species (estimating the number of shared species for two communities based on frequency data or multiple incidence data) 

Part III: Prediction (predicting the number of new species that would be discovered in a second survey, based on frequency data from an initial survey) 

Part IV: Diversity Index (estimating various diversity indices including species richness, Fisher’s alpha index, Shannon’s entropy and Simpson’s index as well as their effective numbers of species based on sample abundance or frequency data) 

Part V: Two-Community Similarity Index (estimating various similarity indices for two assemblages based on abundance data or multiple incidence data. The incidence-based indices include the classic Jaccard, Sørensen and Lennon et al. (2001) indices; the abundance-based indices include the Bray-Curtis, Morisita-Horn and two newly developed abundance-based Jaccard and Sørensen indices)

Part VI: Multiple-Community Diversity Measure (estimating a class of generalized Morisita similarity/dissimilarity indices for more than two communities) 

Part VII: Genetics (applying Part VI to estimate allele similarity and differentiation for multiple-subpopulation genetic data)

PAST

PAST is a practical tool designed to help you analyze scientific data by calculating statistical indicators and drawing plots. The program comes with a large variety of analysis techniques that can be applied with just a few clicks.

When running experiments or gathering demographic data, scientists often need to run in-depth analysis by calculating trends, correlating data or interpolate the samples in order to present the conclusions of their studies during conferences or seminars.

You can use this program to manipulate data and apply various analysis methods. In order to enter the data you can simply open an Excel worksheet, text file or a raw data file. You also have the option to paste the values from another application.

Before processing the values you can insert rows, specify a name for each column and remove details that are not relevant for your study. Additionally, you can specify a counter and transpose the entire range.

The program allows you to transform the data by subtracting the mean value or converting the values to 10-base logarithms. Advanced options such as Box-Cox transformations enable you to normalize the data distribution.

In order to visualize the results of a certain experiment, the user has the possibility to generate a histogram or percentile plot. You can adjust the interval values, character orientation and overall size before exporting or printing the output.

The statistics section includes univariate and multivariate analysis methods such as variance analysis, intraclass correlation or canonical correspondence. Moreover, the app is able to use linear or polynomial models and analyze the data diversity or geometric correlation.

Although the basic statistical indicators such as mean, median or deviation are available, the program requires experience with data analysis in order to interpret the results of each analysis.

If you need to analyze statistical data, PAST is a powerful program that includes a large variety of tools. In order to understand the available methods you should download the manual available on the developer’s website.
