Work on the DELTA Euphorbiaceae key started in 2002 as a one-year undergraduate project. The generic descriptions in Genera Euphorbiacearum, comprising Centroplacaceae, Euphorbiaceae senu stricto, Pandaceae, Phyllanthaceae, Picrodendraceae, and Putranjivaceae, were digitised and further standardised. Aimeé Galster also illustrated each character state where possible. Over the following years the key was tested and continually improved in the Malpighiales Section of the Kew Herbarium during routine naming sessions. The size and diversity of Euphorbiaceae sensu lato, and the wealth of data contained in this key is such that it is far from perfect, but testing by more specialists will hopefully further improve the accuracy of the database behind the key. The Kew Malpighiales Team welcomes any comments and corrections from users, and will regularly integrate them in updates. ... [Information of the supplier]
Interactive Tree Of Life is an online tool for the display and manipulation of phylogenetic trees. It provides most of the features available in other tree viewers, and offers a novel circular tree layout, which makes it easy to visualize mid-sized trees (up to several thousand leaves). Trees can be exported to several graphical formats, both bitmap and vector based. There are several pre-computed trees available for display, including the main Tree Of Life, described in Ciccarelli, et al., 2006. In addition to the precomputed trees, you can upload and display your own trees and data, using the 'Data upload' page or through your personal user account. Use the tabs on the top of the page to navigate or click the trees below to proceed to the interactive pages. Extensive help pages, which provide detailed explanation of iTOL's interface and functions, are available. ... [Information of the supplier]
JSim is a Java-based simulation system for building quantitative numeric models and analyzing them with respect to experimental reference data. JSim's primary focus is in physiology and biomedicine, however its computational engine is quite general and applicable to a wide range of scientific domains. JSim models may intermix ODEs, PDEs, implicit equations, integrals, summations, discrete events and procedural code as appropriate. JSim's model compiler can automatically insert conversion factors for compatible physical units as well as detect and reject unit unbalanced equations. JSim also imports the SBML and CellML model archival formats. JSim downloads are available as precompiled binaries (Linux, MacIntosh, Windows) or source code. JSim can also run as an applet within your web browser. JSim is provided free for non-commercial use as a public service by the National Simulation Resource at the University of Washington. ...

The JUICE program is a widely used non-commercial software package for editing and analyses of phytosociological data. It is continually developed since 1998 at the Masaryk University in Brno, Czech Republic. Program functions are fully described in English manual. It makes use of the previously-developed TURBOVEG software for entering and storing such data and it offers a quite powerful tool for vegetation data analysis. Various options include classification using COCKTAIL, divisive and aglomerative classification methods, calculation of interspecific associations, fidelity measures, average Ellenberg indicator values, preparation of synoptic tables, automatic sorting of relevé tables, and export of table data into other applications (text editors, table processors or mapping packages). JUICE is optimised for use in association with TURBOVEG which is the most widespread database program for storing phytosociological data in Europe. However, three other import formats are available for other users. ... [Information of the supplier]
LisBeth is a standalone computer program that implements the three-item analysis (3ia) for cladistic research in phylogenetics and biogeography. The development of the 3ia approach begun with the works of Gary Nelson, Norman Platnick, Pauline Ladiges (Nelson and Ladiges 1991; Nelson and Platnick 1991; Nelson and Ladiges 1992; Nelson and Ladiges 1996). Recent advances of the method are due to the research by David M. Williams and Malte C. Ebach among others. LisBeth is the only package of computer programs specially designed for three-item analysis (3ia), i.e. phylogenetics and cladistic biogeography. LisBeth graphic user interface (GUI), allows representing hypotheses of homology among taxa or areas directly as rooted trees or as hierarchies, i.e. as nested Venn diagrams. The GUI is used to enter, edit and visualize the hypotheses of homology and the results of their combination using 3ia. It allows a complete description of each character (each tree) and each state (each component of the tree). It may be used for systematics, and it is being adapted for cladistic biogeography. ...

Use this site to download software based on the maximum-entropy approach for species habitat modeling. This software takes as input a set of layers or environmental variables (such as elevation, precipitation, etc.), as well as a set of georeferenced occurrence locations, and produces a model of the range of the given species. ...

MOLMOL is a molecular graphics program for displaying, analyzing, and manipulating the three-dimensional structure of biological macromolecules, with special emphasis on the study of protein or DNA structures determined by NMR. The program runs on UNIX and Windows NT/95/98/2000 and is freely available. [Information of the supplier]
mx (preferred reference all lowercase) is a Ruby-based platform that consists of a Ruby on Rails (RoR) application and various supporting gems/libraries. Initially conceived and developed as a collaborative web-based content management system for biosystematists mx now has a wide range of functionality much of which can broadly categorized under the umbrella of biodiversity informatics. ...

PHYLIP is a free package of programs for inferring phylogenies. It is distributed as source code, documentation files, and a number of different types of executables. These Web pages contain information on PHYLIP and ways to transfer the executables, source code and documentation to your computer. [Information of the supplier, modified]
PlutoF provides cloud database and computing services for the taxonomical, ecological, phylogenetical, etc. research. The purpose of the platform is to provide synergy through common modules for the classifications, taxon names, analytical tools, etc. It allows to address integrated questions in ecology and coevolution of taxa. Different types of the species occurrences, viz. preserved specimens, DNA sequences, human observations, references can be stored in PlutoF as well. PlutoF has no restrictions on taxon and geographic coverage and therefore can be used for the databasing interacting taxa. It includes also collection management module. ...
