Binomial NomenclatureEvery organism that is classified

has a scientific name.This name has two partsThe first name is the name of the

genus and is capitalized.The second name is the name of

the species and is written in lower case.

Acinonyx Jubatus Aconitum columbianumArtiodactyla suidae

Taxonomic KeysA taxonomic key is paired

statements that give characteristics of an organism.

You choose which statement applies to the organism you are trying to classify.

You continue through the key by stating the characteristics.

Once you have completed the steps, you arrive at the scientific name of the organism.

Taxonomic Key Example A taxonomic key is a tools used to identify and classify organisms. Most keys consist of a set of paired statements describing a certain trait. By choosing from a series of these paired traits,

a biologist can place an unknown organism in smaller and smaller groups until the organism is either identified or proved to be something new. Use the following key to identify the leaves on the next page. Write the steps used and the scientific and common name of each tree in the spaces provided. (use the leaf terms at the bottom of the leaf page to help) 1a. Leaves needlelike: Go to 2 1b. Leaves broad with flattened surface or blade: Go to 6 2a. Needles up to 2.5 cm long: yew, Taxus canadenis 2b. Needles 5.0 cm or longer: Go to 3 3a. Needles 5.0 to 12.5 cm long: Go to 4 3b. Needles more than 12.5 cm long: Go to 5 4a. Needles in cluster of two: Scotch pine, Pinus sylvestris 4b. Needles in clusters of four or five: white pine, Pinus strobus 5a. Needles in clusters of two: black pine, Pinus nigra 5b. Needles in clusters of three: ponderosa pine, Pinus ponderosa 6a. Leaves divided into separate leaflets or little leaves: Go to 7 6b. Leaves all in one piece; no leaflets: Go to 8 7a. Leaves with five to seven leaflets, bottom pair smallest: shagbark hickory, Carya ovata 7b. Leaves with thirteen to forty one leaflets: tree of heaven, Ailantbus altissima 8a. Leaf edge smooth, no saw-teeth: flowering dogwood, Cornus florida 8b. Leaves saw-toothed or lobed: Go to 9 9a. Leaves saw-toothed, veins like barbs on a feather: beech, Fagus grandifolia

Taxonomic Key PracticeLook at the salamander pictures

on your table.Study the dichotomous key to

find the name of your salamanderHave everyone on your table find

the name of a different salamander

Include a description and a name of your salamander.
