Corema - Collection and Research Management


Corema is a flexible and fully featured software package for all types of biological collections. The system can be used by institutions, societies and private collections such as natural history museums, herbaria and zoological gardens.


deegree - Free Software for Spatial Data Infrastructures

deegree is a Java Framework offering the main building blocks for Spatial Data Infrastructures. Its entire architecture is developed using standards of the Open Geospatial Consortium (OGC).

DELIA - The DELTA Integrator

DELIA, the DELTA Integrator, extends the utility of DELTA format files by providing functionality that the (separate) CSIRO DELTA System software package can't. It provides a way to manage multiple datasets coded in DELTA and is designed to integrate with and complement the existing DELTA System suite of programs. It is designed for those DELTA users who are interested in managing their data in an integrated environment. We found only a beta version available.


The DELTA System is an integrated set of programs based on the DELTA format. The facilities available include the generation and typesetting of descriptions and conventional keys, conversion of DELTA data for use by classification programs, and the construction of Intkey packages for interactive identification and information retrieval.


DesktopGarp is a software package for biodiversity and ecologic research that allows the user to predict and analyze species distributions. GARP tries, interactively, to find non-random correlations between the presence and absence of the species and the values of the environmental parameters, using several types of rules. Each rule type implements a different method for building species prediction models. GARP as input takes enivonmental data and species occurrence localities. It generates random absence data.



DIVA-GIS is a free and open source geographic information system (GIS) to make maps of species distribution data and analyze these data.

DIVA-GIS Annapurna

Another version of the same DIVA-GIS programme.

Diversity Workbench

The Diversity Workbench is work in progress, aiming at developing a set of information models and application components that collaborate through agreed software interfaces. That is, each component of the Workbench applications uses services from other applications, but at the same time does not need to know about the internal design and implementation of them (encapsulation principle). The goal is increased reuse and collaboration across project and national borders.

DiversityDescriptions (DeltaAccess)

A SQL interface to DELTA, the Description Language for Taxonomy, implemented in Microsoft Access 97, 2000, and 2002 (= XP). DeltaAccess can be used in 3 ways: a) You can use DeltaAccess simply as a module to import DELTA coded text files into a database of your choice and then write an independent application for that database (e. g. a web interface). b) You can keep your data in DELTA coded text files, and use DeltaAccess as a one-way import tool to analyze your data (incl. cross-tabulations, and charts), print form sheets to edit your data off-line, or to generate dynamic html/www output. c) You can use DeltaAccess as the central data repository around which your work is organized.


The Diversity Mobile Wiki is a platform for information networks in the context of DiversityMobile (for mobile devices and smartphones), the Diversity Workbench and the DaltOn framework. Currently it is focused on a DFG-funded project "Setting up an Information Network on Biological Research Data gained in the Field up to the Sustainable Storage in a Primary Data Repository (I-B-F)".


DiversityNavigator is a rich-client application for viewing, editing, and analyzing data. DiversityNavigator is written in java and can access both local and server based databases. It is compatible to a variety of database engines.


Uses a point-to-point similarity metric (Gower metric) to assign a classification value to a potential site based on its proximity in environmental space to the most similar positive occurrence location. Similarity between the site of interest and each of recorded present occurrence location is calculated by summing the standardized distance between the two points for each predictor variable. The standardization is achieved by dividing the distance by the predictor variable range for the presence sites, equalizing the contribution from each predictor variable. The standardized distance is subtracted from 1 to obtain the complementary similarity.

Dryades (Italian branch of the European Project KeyToNature)

Dryades is the Italian branch of the European Project KeyToNature. The website of Dryades gives access to interactive guides for the identification of plants, fungi and animals, to iconographical archives, and to databases on the biodiversity of Italy. A special section is dedicated to products specifically designed for schools. Identification tools are available in 10 languages.

Some of the projects available on the website are public and some are not.


Earth Cape

EcoSim. Null model software for ecologists

EcoSim allows you to test for community patterns with non-experimental data performing Monte Carlo randomizations to create “pseudo-communities”, then statistically compares the patterns in these randomized communities with those in the real data matrix.



EndNote connects to Internet-based libraries of reference data (there are many free-access databases in addition to those that your organization or institution subscribes to) and locate the references for citation. EndNote stores, catalogues and indexes these references in your own custom reference databases, together with images, figures, files and links that you want to include or cite. And EndNote integrates into your word processor to make it easy to insert citations and create bibliographies and figure lists, with every entry automatically and consistently formatted in the style you, or your publishers, prefer.
