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.

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, genus, species, subspecies (variety and forma in plants) and categories between the larger categories) Table 1. Some Large Divisions of Life on Earth.
Flatworms, Roundworms, Arthropods, Echinoderms, Urochordates, Hemichordates, Cephalochordates, Chordates Clubmosses, Ferns, Gymnosperms, Angiosperms 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. _________________________________ The list in Table 2 is a conglomeration from bioblitz lists, Michigan banana, poor man’s banana, and West Virginia 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 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. taxonomy 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). 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 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 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 (Ohio), Michigan-banana __________________________________________ (Michigan), Poor Man's-banana (by underpaid professors), and West-Virginia-banana (West Virginia).

It partially or almost totally defoliates Platanus occidentalis , rendering trees unsightly Specific ecological roles. Leaves are food of many insect with spring leaf loss. Platanus occidentalis trees usually species including Cloudywing Butterflies and Porthetria refoliate in July in the WDCA. Because of this disease, dispar (Gypsy Moth).

People have introduced PL in Europe and GU President Leo O’Donovan planted the Millenium Oak (Q. alba ) in Healy Quadrangle in 2000. In 2004, 17-year Cicadas killed many small limbs of this tree when they laid Specific ecological roles. Procyon lotor consumes bird eggs in the limbs. The tree recovered well from this eggs, birds (infrequently) insects, fish, fruit (including trimming. GU spared a huge Q. alba when it erected Henle acorns and walnuts) , worms, and mammals (infrequently). I sometimes see Procyon lotor foraging for garbage in GU dumpsters. _________________________________ ☐ Sciurus carolinensis Gmelin, 1788; Eastern Gray Squirrel ☐ Quercus alba L., 1753, White Oak n.
