Welcome to Bio*Pedia!
Bio*Pedia is a repository of descriptions of organisms and a partner of the Encyclopedia of Life (EOL). Descriptions added to Bio*Pedia will be harvested at regular intervals, and will appear on EOL species pages.1
Want to contribute a text description for an EOL species page now? Here are a few easy steps to get started:
- Please register with Bio*Pedia or login if you are already registered (Bio*Pedia has a separate registration system from EOL).
- If you are not registered yet, please fill in all fields in the registration
form. You will receive an e-mail with a registration confirmation link shortly. After you click this link, you can begin contributing to Bio*Pedia and EOL.
- Type the scientific name of the species that you wish to add a description to (without author and year) into the search box, select and jump to the species name, and click on the "Add description" link in the upper left corner of the page. Type your description into the lower (yellow) box, choose the appropriate license, click "Save description", and your description will immediately appear in Bio*Pedia, which means that it is on the way to EOL!1
1Please note that your description will not appear immediately on EOL Species Pages. If submitted descriptions are deemed inappropriate or inaccurate, they may not be included in EOL.
Description of Parabasalids:
Circumscription: Mostly flagellated protozoa, mostly commensals in insects or parasites. Some (hypermastigids) may have very large numbers of flagella and are usually symbionts in the intestines of wood-eating insects, others (trichomonads) may have an undulating membrane. An axostyle may be visible. A few species are free living. Ultrastructural identity: No mitochondria. All cells (excepting aflagellated taxa) with at least one cluster of four basal bodies, which are the source of microtubular roots. Dictyosomes are well developed, often numerous, and may be associated with a nonmicrotubular rootlet, the parabasal fibre. Cell surface naked, no extrusomes. Mitosis with intact nuclear envelope and with spindle microtubules lying external to the nucleus. Synapomorphy: Flagellated protists with a parabasal apparatus of dictyosomes anchored to a striated root.
