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]
You can use the general search at the top of every page to find a particular fish by its scientific, common or family name or use the fish finders on the Find a fish page to locate your species of interest. [Information of the supplier, modified]
The release of Australian Tropical Rainforest Plants Edition 6 (RFK6) represents another significant milestone in the development of this information system for identifying and learning about plants in Australian tropical rainforests. Each edition of the system since 1971 has made significant advances in the coverage of plant groups, the numbers of species included, the effectiveness of the identification system, and in the utilisation of current technology. The aim of this new edition is to make identifications possible and easier, and make taxonomic information accessible to the wider scientific community and the population as a whole. Australian Tropical Rainforest Plants Edition 6 includes 2553 species in 175 families, and has attempted to include all flowering plant species present in rainforest of northern Australia in the following life forms: trees, shrubs, vines, forbs, grasses and sedges, epiphytes, palms and pandans. Some species are not yet included, primarily due to lack of specimens for coding features. Several new features have been added in response to user feedback and to facilitate the identification of the additional life forms. ... [Information of the supplier]
Bamboos are economically important plants with innumerable uses and many environmental benefits. Improving the availability of information on bamboos is an important step towards the development of sustainable utilization and conservation for this valuable renewable resource, not only in its natural habitats, but also wherever it is cultivated throughout the world. This site was launched in August 2006, primarily as a means to bring together the growing variety of dispersed online tools and information relating to bamboo identification and naming. It also provided an opportunity to disseminate personal publications produced over a 25 year career as a bamboo specialist, working in Asia and in western botanical gardens. Most of these are accessible here as PDF documents or online links. This anniversary also coincides with the publication of the English-language Flora of China bamboo account, a project in which approximately one third of the world’s bamboos are described, arranged more natural system of genera backed up by results of research into their molecular phylogeny. The emphasis of this site is on woody bamboos of Asian origin, especially those from temperate areas, and their cultivation in Europe & the USA. The initial intention was to write a book, but a website seemed a much more flexible, useful and powerful alternative, which could adapt and develop, and link directly to other developing online information. ...

This website provides an introduction to the identification of tree species in Germany, with a database of plant traits and numerous photographs, covering more than 500 indigenous and exotic trees. As a special help for beginners, an illustrated list of the most common trees and shrubs of Germany is available. [Editorial staff vifabio]
This key was designed to be easy-to-use and accessible to a diverse audience. As such, I have focused on describing gross morphology and external features as much as possible. Biologists searching for more detailed information on internal anatomy should consult the references listed at the bottom of each species description page. In some cases it is necessary to observe internal anatomy to make an identification. Following proper narcotisation and preservation some organisms will need to be dissected. For solitary and social tunicates, begin by cutting from the oral siphon towards the base until the tunicate opens like a book. Cut through the tunic, the body wall, and the pharynx, but carefully avoid the digestive and reproductive tracts. Remove the pharynx from the tunic (i.e., sever the pharynx from the digestive tract). Zooids and internal anatomy of colonial species can be observed by dislodging zooids from the tunic, either by prodding the colony surface or by cutting the colony parallel to the long axis of the zooids. ...

This preliminary key for the identification of sedges, rushes and other simlar plants (Cyperaceae, Juncaceae, Juncaginaceae, Scheuchzeriaceae) deals with species that occur in Switzerland. It is based on numerous published identification keys and treatments of the respective plant groups, supplemented with observartions by the author. ... [Editorial staff vifabio]
