ActKey was developed to enable ready-access to on-line interactive keys, including partly illustrated implementation of the punched card system for flowering plant family identification (by Hansen, B., and K. Rahn. 1969. Determination of angiosperm families by means of a punched-card system. Dansk Botanisk Arkiv 26:1-46 + 172 punched cards) and many other sources. ...

Whose Tadpole is it? Although adult amphibians live generally well hidden and shy, their larvae occur abundantly and are quite easy to catch. However, it user to be very difficult to identify the tadpoles. Berninghausen's -electronic- and waterproof field guide makes it possible even for the inexperienced to dertemine the species on the spot within minutes. ... [Information of the supplier]
This interactive guide is addressed to anyone who is interested in the flora of Estonia. It includes c. 1100 plant species (out of ca 1500 species recorded from Estonia), incl. several introduced woody species which are cultivated in parks and orchards. Some plants which are difficult to separate even for specialists are excluded from this key, e.g. many species of Alchemilla, Craetagus, Hieracium, Rosa, Salix, Taraxacum etc. Several very rare species are excluded as well from the present version. This guide was prepared within the project KeyToNature, in cooperation between the University of Trieste (Italy), the University of Tartu and the Estonian University of Life Sciences (Estonia). Aino Kalda, Thea Kull , Ülle Reier have provided important input. Rein Kalamees, Jaan Liira, Jaanus Paal, Kersti Püssa, Elle Roosaluste, Kai Rünk, Andres Saag and Tiina Talve put at our disposal several pictures. ... [Information of the supplier]

This webpage introduce to the Australian Chilopoda (Centipedes). All subtaxa are presented: Craterostigmorpha (1), Lithobiomorpha (20), Scutigeromorpha (19), Geophilomorpha (43) andScolopendromorpha (45). This online key allows their determination. Furthermore there are short note on biology and distribution. [Editorial staff vifabio]
This site provides a vegetative key to the families of climber species in central Guyana, South America, particularly the Mabura Hill area. Furthermore, a detailed description of all species found in the framework of our research (see below) can be found. In order to use the vegetative key, the first step is to indicate whether a species has simple or compound leaves and whether the leaf arrangement is alternate or opposite. The icons of these leaf characteristics are found on the left side. Clicking on one of the icons will lead to a specific part of the vegetative key, allowing to key out to the family level. Clicking on a family name will result in a list with all climber species in that family. Click left on a family name and a dropdown menu with all the climber species belonging to that particular family will be shown. At the same time, a vegetative key to the species (where available; at this moment only the Menispermaceae) and a species list will appear. By clicking on a species name the corresponding page will be loaded. On that page you will find a vegetative description of the species with drawings and pictures where available. ...

Interaktives Forum zur Erstellung von Bestimmungstabellen für Käfer, das allen Autoren die Möglichkeit gibt, ohne Kosten ihre Erkenntnisse der Allgemeinheit zur Verfügung zu stellen. Gegebenfalls wird auf andere Sites verwiesen, in denen Sachverhalte zur Biologie oder Verbreitung dargestellt sind. Die Familientabellen sind in erster Linie für Anfänger bestimmt und daher nicht streng nach systematischen oder phylogentischen Gesichtspunkten aufgebaut. Der fortgeschrittene Entomologe kann sich aus den alphabetischen oder systematischen Listen gleich die Familie oder Gattung heraussuchen, in der er bestimmen möchte. ...

This side offers an interactive key which is meant to aid the identification of aquatic insects found in North Dakota. It is primarily meant to be used by students, citizen groups, and professionals and be useful to implementing a biomonitoring program. This key is not a traditional dichotomous key. It has been based on 7 years of collections carried out by the North Dakota Department of Health (Bismarck, N.D.) and 5 years of collecting carried out by Dr. Andre DeLorme's macroinvertebrate lab at Valley City State University. A list with short biographies of the participating scientists completes the side. ... [Information of the supplier, modified]
This side offers an interactive key which is meant to aid the identification of the non-insect aquatic macroinvertebrates found in the rivers and streams of North Dakota. It is primarily meant to be used by students, citizen groups, and professionals and be useful to implementing a biomonitoring program. This key is not a traditional dichotomous key. It includes many different groups such as snails, daphnia, crayfish, leeches, and oligochaetes. For some of the groups it goes all the way down to species level. Other groups may only go down to the Order, Family or Phylum level (the sponges and flatworms).The key has been based on 7 years of collections carried out by the North Dakota Department of Health and 5 years of collecting carried out by Dr. Andre DeLorme's macroinvertebrate lab at Valley City State University.
