Key SearchWelcome to the Lucidcentral Key Search

There are two ways you can search for a key in the Lucid key database. First, you can type in a word or words in the “Search” box to the right of the screen and press Go. This search will display all those keys that have the word(s) you entered in the title of the key. The alternative way is to use one or a number of the search categories below, using the drop down menus. So, for instance, you could search for an internet key (under Media/Deployment), of Higher plants (Taxonomic scope), terrestrial (Habitat) and Australia (Geo Scope).

We recommend that you check whether you have the latest (free) version of Java Runtime Environment and if necessary upgrade to the latest version when running keys based on the Lucid Player applet.

This key was created using Phoenix v1, which works as a dichotomous key. The key is designed only for use in New Zealand. This is the first graphic key to Tachinidae genera in New Zealand, so any feedback would be appreciated. Images were taken by F-R Schnitzler at Landcare Research with NIS Elements, Helicon Focus and Combine ZP.

Larval Fish and Egg Key (Freshwater)  --  VISIT
 Views: 152

Updated: Mon 04/18/2016 @ 09:43

This project was initiated to develop a web-based taxonomic key for the Great Lakes Basin to identify larval fish and eggs in order to assist the power industry to comply with new 316(b) regulatory requirements for the characterization and quantification of entrained fish species. The web-based key is structured around existing print keys developed by Nancy Auer (Michigan Tech), with updates from Howard Kowalyk (SENES) review support from Paul Patrick (SENES) and others.

This Electric Power Research Institute funded project is initially developed as an updated regional resource to support compliance efforts, however it is openly accessible to anyone who interested in larval and egg species identification. Identification of freshwater fish based on characteristics of egg, yolk sac larvae, and/or larvae. References used to build this key include: 1) "Identification of Larval Fishes of the Great Lakes with Emphasis on the Lake Michigan Drainage," N. Auer editor, with forward prepared by Carlos Fetterolf, Jr., Executive Secretary, Great Lakes Fishery Commission, 1982; and 2) "Fish Life Histories", H. Kowalyk, with emphasis on egg stage.

We are grateful to many friends and colleagues working at the WA Herbarium for supplying diverse data, images, maps, ideas, and taxonomic and computing expertise that have made the development of this data set possible. In particular we wish to thank Rob Davis for photos and taxonomic help, Mike Hislop, Steve Dillon, and Margaret Langley for their help with taxonomic queries. We note that the photographic species images available here come from the WA Herbarium’s online plant information system, FloraBase, and represent the work of a team of dedicated volunteers. The maps, also part of FloraBase, represent specimens held at the WA Herbarium.
