Current Proceedings in The Taxonomicon

  • Taxon (Nomenclature) page:
    • SN2000 author citation. A uniform author citation based on a combination of several International Codes of Nomenclature, which may include non- or less conventional attributes.

  • Taxon (Taxonomy) page:
    • Concise hierarchy shows only the principal ranks (kingdom, phylum, class, order, family) of the hierarchy (e.g. Genus Homo).
      The Tree View of the Taxon (Relationships), Topic, and Advanced Search Results pages is based on this hierarchy.
    • PhyloCode clade names are represented by single generic clade names that may have multiple phylogenetic definitions (e.g. Aves).
  • Taxon (Properties) page:
    • Basic information displays a short summary on geological/geographical distribution, habitat, and/or conservation status (e.g. Species Homo sapiens). Details may be found on the Taxon (Properties) or Taxon (Relationships) pages, but usually for species only.
  • Taxon (Relationships) page:
    • View List/Tree displays either a collapsible list of all related taxa/entities (e.g. North Sea), or a collapsible tree of related taxa (primarily species) using the concise hierarchy (e.g. North Sea).
  • Topic page:
    • Categories are collapsible (e.g. nocturnal).

  • Quick Search (Taxon by Authorship):
  • Taxon (Hierarchy - Links) subject header:
  • Taxon (Nomenclature - Links) navigation list:
    • The navigation list reflects the Taxon Hierarchy regarding Source, Root, Invalid names, and Alternative positions. When the Root is not set explicitly, the list only shows the immediate parent, the siblings and the children of the current entity. The list is always ordered by name, regardless of rank, position, or status.
  • Taxon (Hierarchy) page:
    • View Original/Conventional. The original view (default) tries to represent a classification as close to its source as possible by using the actual notations (including errors) of scientific names, authorship, and common names. Systema Naturae 2000 displays scientific names in their long form (interpolated names), and may use a quite unconventional way of author citation by combining multiple international codes of nomenclature to reflect the most of the nomenclatural history. Synonyms refer to entries within the source. The conventional view tries to represent the classification as close to the requirements of the international codes of nomenclature as possible. The conventional scientific names and author citations are the ones being used for searching and displaying the results. Synonyms refer to entries within Systema Naturae 2000.
    • View Classification/Cladification. View Classification shows the entire classification including all entities available. View Cladification shows only a subset of the classification by removing redundant (monotypic) taxa. Non-monophyletic taxa are displayed in red to indicate that these taxa do not belong in a cladification, e.g. Empire Prokaryota. Furthermore no ranks are shown in the tree, but clade types are, e.g. Supergroup Opisthokonta.
    • Order by Position/Name shows the position and shows the names in numerical (systematic) order (by default) or hides the position and shows the names in alphabetical order. For biological taxa the numerical order attempts to reflect the phylogenetic relationships among taxa, and may indicate whether a taxon belongs to a stem group or a crown group.
    • Set/Reset Root sets the root of the tree (as used by the Taxon Hierarchy page and the navigation lists on the other taxon pages) to the current entity (e.g. Class Aves down to Corvus corax), or resets the root to the ultimate root of the selected source (e.g. Natura for Systema Naturae 2000).
    • Set Bookmark bookmarks an entity to go to or to compare with.
    • Go to Bookmark
    • Pin/Unpin Bookmark shows/hides the relationship between the current entity and the bookmarked entity (e.g. Show the relationship between a human and an East African lungfish)
  • New Taxon (Taxonomy) page (e.g. Genus Homo):
    • Show Current/Alternative positions within Systema Naturae 2000
    • Show Original/Subsequent positions
    • Show Original/Subsequent entries
    • Show Historical positions within Original classifications
    • Show Number of Subtaxa (used to be on the Nomenclature page)
    • Show Clade Definitions (e.g. Amorphea, Passer domesticus)
  • Taxon (Bibliography) page:
  • Reference page:
  • Person Index/Details page:
    • Show standard form for authors, e.g. L. for Linnaeus
    • Show acronym for organizations, e.g. ICZN for International Commission on Zoological Nomenclature
    • Show relationships, e.g. between W.J. Hooker and J.D. Hooker

  • Quick Search (* = previously implicit wildcards are replaced by optional explicit ones ('*', '?') to allow for searching on exact words and phrases):
    • Search Entity by Scientific Name* replaces Taxon by Scientific Name (all groups) to include objects and phenomena (e.g. Ara, Pseudo*)
    • Search Entity by Epithet* replaces Taxon by Epithet to include objects (e.g. ruber*, everest)
    • Search Entity by Identifier (e.g. UMa, Cu, DNA, H2O, 79)
    • Search Entity by Common Name* replaces Taxon by Common Name (English) and Taxon by Common Name (Dutch) to include common names for taxa, objects and phenomena in any language (e.g. ?ats, [ck]at, boar, wine grape)
    • Search Taxon by Scientific Name (genus group)* (e.g. Sus)
    • Search Taxon by Scientific Name (species group)* returns all species-group taxa within the given genus (e.g. Homo)
    • Search Taxon by Scientific Name (below species group)* returns all infrasubspecific taxa within the given genus c.q. species (e.g. Tulipa, Brassica oleracea)
    • Search Object by Number used for astronomical objects (e.g. 1)
    • Search Phenomenon by Name replaces Disease to include other phenomena (e.g. influenza, earthquakes, eruptions)
      diseases and related health problems are now treated as phenomena instead of property items
    • Search Homonym* (e.g. Ara)
    • Search Organization by Name (e.g. ICZN, International)
    • Search Reference by Year (e.g. 1758)
    • Search Reference by Title replaces Article by Title to include journals, books, chapters, websites, etc. (e.g. systema naturae, classification)
  • Advanced Search/Topic Index:
    • Search taxon by Geographic region is deprecated
      geopolitical regions are now treated as objects instead of topics
  • Entity (i.e. Taxon, Object, and Phenomenon) Pages:

07 Apr 2012

  • Taxon Hierarchy:
    • Browse Tree replaces Browse Classification and Browse Cladification

21 Mar 2011

  • Valid links (The Taxonomicon):
  • Valid links (Systema Naturae 2000: original website):
  • Conversion of The Taxonomicon Editor application from Visual Basic 6.0 and Access 2003 database to .NET 2.0 (C#) and SQL Server 2008 R2 database. The new application is much more sophisticated, allowing me to be more accurate especially regarding taxon properties and taxon relationships.
  • Many new kinds of properties and relationships have been created that will become available in future updates.
  • Quick Search:
    • Search Object (e.g. planets, surface features, ecoregions, populated places, specimens, events)
  • Advanced Search/Topic Index:
    • Search taxon by Global 200 ecoregion (deprecated): Ecoregions are now treated as objects instead of properties
    • Search taxon by Alkaloid (removed): Specific alkaloids are now treated as taxa instead of properties
    • Search taxon by Toxin (removed): Specific toxins (e.g. botulin) are now treated as taxa instead of properties
    • Search taxon by Functional class: Toxin is now regarded as a functional class of a chemical substance along with many other classes
