For no good reason, here's a set of trivia questions about biological taxonomy and nomenclature. Excuse the possible zoological bias - I am a zoologist, after all. How many can you answer? They start off easy, but (hopefully) they get trickier.
1. Current rank-based taxonomy is based on seven primary ranks. Which two were not used by Linnaeus?
2. What are the five codes of biological nomenclature currently in action?
3. Name one group of organisms not governed by any of these five codes.
4. What is the earliest publication using binomial nomenclature to be currently recognised by the ICZN?
5. When and what was the earliest formal zoological nomenclatural code proposed? What was the earliest botanical code?
6. What do the letters 'VP' and 'AL' mean as part of a bacterial name?
7. Kathablepharis and Katablepharis are different spellings for the name of the same organism. Each is the one spelling that must be used, while the other spelling is invalid. Explain.
8. The name Oedicnemidae was published by Gray in 1840. The name Burhinidae was published by Mathews in 1912. Both refer to the same family, for which the valid name is Burhinidae. Why?
9. If two or more taxa have the same name, and fall under the scope of the same code, then their names are homonyms, and only one can be valid. Pupa affinis Rossmaessler 1839, Pupa affinis Aradas & Maggione 1843 and Pupa affinis (Adams 1855) are all names for animals, but they are not considered homonyms. How is this possible?
