Glossary for Etheostoma histrio
- aquatic habitat
- A habitat that is in or on water.
- An area of water bordered by land on three sides.
- The physical confine of a river, slough or ocean strait consisting of a bed and banks.
- The general region of indefinite width that extends from the sea inland to the first major change in terrain features.
- conservation status
- A plane angle unit which is equal to 1/360 of a full rotation or 1.7453310^[-2] rad.
- This taxon is still in existence, as opposed to extinct.
- extinction status
- Indicates whether a taxon is extant (living today) or extinct.
- fresh water
- freshwater habitat
- A habitat that is in or on a body of water containing low concentrations of dissolved salts and other total dissolved solids (<0.5 grams dissolved salts per litre).
- Gravel is an environmental material which is composed of pieces of rock that are at least two millimeters (2mm) in its largest dimension and no more than 75 millimeters.
- ground water
- A category or description of the habitat in which the Event occurred.
- Large river biome
- The geographic latitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are north of the Equator, negative values are south of it. Legal values lie between -90 and 90, inclusive.
- least concern
- A taxon is Least Concern when it has been evaluated against the criteria and does not qualify for Critically Endangered, Endangered, Vulnerable or Near Threatened. Widespread and abundant taxa are included in this category.
- The geographic longitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are east of the Greenwich Meridian, negative values are west of it. Legal values lie between -180 and 180, inclusive.

- population trend
- An artificial body of water, often contained by a dam, constructed for the purpose of water storage.
- A shallow stretch of a river or stream, where the current is above the average stream velocity and where the water forms small rippled waves as a result. It often consists of a rocky bed of gravels or other small stones.
- Natural freshwater surface streams of considerable volume and a permanent or seasonal flow, moving in a definite channel toward a sea, lake, or another river; any large streams, or ones larger than brooks or creeks, such as the trunk stream and larger branches of a drainage system.
- A naturally occurring granular material composed of finely divided rock and mineral particles.
- Sediment is an environmental substance comprised of any particulate matter that can be transported by fluid flow and which eventually is deposited as a layer of solid particles on the bedor bottom of a body of water or other liquid.
- Any material within 2 m from the Earth's surface that is in contact with the atmosphere, with the exclusion of living organisms, areas with continuous ice not covered by other material, and water bodies deeper than 2 m.
- Linear body of water flowing on the Earth's surface.
- stream bank
- The sloping margin of a stream, serving to confine it to its natural channel.
- A stream or river which flows into another river (a parent river) or body of water but which may not flow directly into the sea.
- type specimen repository
- The institution that holds a type specimen for a given species. The recommended best practice is to use the identifier in a collections registry such as the Biodiversity Collections Index (http://www.biodiversitycollectionsindex.org/).
- undersea feature
- water body
- A flowing body of water.
- The separation between neighbouring drainage basins (catchments). In hilly country, the divide lies along topographical peaks and ridges, but in flat country or on a high plateau (especially where the ground is marshy) the divide may be invisible - just a more or less notional line on the ground on either side of which falling raindrops will start a journey to different rivers, and even to different sides of a country or continent.
- An area that is inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions.
- Land having a cover of trees, shrubs, or both.
