Goals

Increase our nature and scientific literacy in view of Earth Stewardship. Learn about local biodiversity. Learn about local communities. Pool our knowledge and update this list as a group. ______

This document

I started this document in 2009 for my Forest Ecology class, and hope to update it over the years. This is primarily an annotated list of local biota. I include more detailed information for selected taxon in Table 5. For full information you should consult reference books and scientific papers, some of which I list in the References.

Please give me corrections, additions, suggestions, etc.

A wonderful introduction to the biota of the U.S. Mid-Atlantic Region is Alden, P., B. Cassie, J. D. W. Kahl, E. A. Oches, H. Zirlin, and W. B. Zomlefer. 2007. National Audubon Society. Field Guide to the Mid-Atlantic States. Alfred A. Knopf, New York, NY. 448 pp. ______Background

How do many biologists now classify life from large through small taxonomic groups (= taxa)?

(domain, phylum, class, order, family, , species, subspecies (variety and forma in plants) and categories between the larger categories)

Table 1. Some Large Divisions of Life on Earth.

Taxon English name Approximate Examples number of species

Note: There are likely over 20,000 species in the the Washington, D.C., Area. Due to time and space limitations, I include only some of these fascinating taxa below, emphasizing the Potomac Valley Area. Species counts are from Brown and Brown 1972, 1984, and other sources. ______

Disclaimers, Etc. The list in Table 2 is a conglomeration from bioblitz lists, Michigan banana, poor man’s banana, and West lists from my forest ecology course, and other lists. The list banana, respectively. Why the capitalized names? Some is far from complete. I have not included all known biologists including myself consider the so called common nonscientific names and scientific names of listed names of plants, in truth, to be proper English nonscientific organisms. Further, this list is obviously very incomplete. names (that is, proper nouns). Each of the above English I include full names of some of the taxon authors for fun. I names stands for a total species — the Pawpaw. Why the have not yet had a chance to italicize all genus, species, hyphens? Well, I’m an admitted hyphenist and a commaist and variety names. for enhanced-communcation reasons. Regarding the ______hyphens, I follow the lead of some prominent botanists (e.g., Stanwyn G. Shetler) who evidently think we should Organism Consumption. I am not responsible for anyone use nonscientific names that indicate true botanical who consumes anything on field trips organized by me. of plants ( Shetler and Orli 2001, 2002; Barrows ______2011). Pawpaw is in the Custard-apple Family ______(Annonaceae), not the Rose Family (which includes apple species) or the Banana Family (which includes the Antianthropocentrism and Demystifying Organism Names Bananas, and Birds-of-Paradise, and Traveler’s-palms). — Plants Therefore, we should indicate that Pawpaw is not an apple or a banana through hyphenation or joining words. For People have given organisms many names, both proper example, we could write “Custard-apple” or “Custardapple.” names (nonscientific names) in Chinese, English, French, Further, I use a proper noun such as “Bananas,” as a German, Indian, Japanese, Russian, and so forth as well synonym for the genus Musa which includes all Banana as scientific names. These thousands of names and rules species of the world. If all of these names and rules are of English and binomial nomenclature confuse many of us. driving you bananas and bandanas, you are likely not At Georgetown University, students learn some classical alone! biology in my ecology courses when I present a learning Finally, I respectfully consider the use of proper nouns for module called “Demystifying Organism Names.” Some organism names to be a means of paying homage to students are surprised that there are rules of binomial biodiversity and a conceptual move away from too much nomenclature and the rules differ among taxonomic groups rampant, and even destructive, anthropocentrism that we as well as some other facts about organism names. I’ll say constantly perceive around us. Why should we make the just a little about plant names here. name of just one individual of one of the millions of species on Earth such as Roger Tory Peterson a proper noun, yet For example, a plant that I usually call Pawpaw or Asimina not capitalize the name of entire species? triloba is also called the Common Pawpaw, Custard-apple ______(in Central USA), Hoosier-banana (), Michigan-banana ______(Michigan), Poor Man's-banana (by underpaid professors), and West-Virginia-banana ().

Why are human names attached to this plant’s ______scientific name? Carolus Linnaeus, the father of binomial Domain Archaea, Archaeans (WDCA, possibly 100 spp.) nomenclature, originally named this plant. In 1817, Felix Michel Dunal (French biologist, 1789–1856) published his Clade Euryarhaeota (Greek eurys, broad in reference to work that reclassified Pawpaw into is current genus the broad range of this clade.
