Concept Reference Code: A15NEA01NAUS
Name Used in Concept Reference: Etheostoma virgatum
Taxonomic Comments: Based on morphological comparison and phylogenetic analyses, Near and Thomas (2015) recognized E. nebra (formerly included in E. virgatum) as a distinct species. Etheostoma basilare and E. derivativum formerly were included in this species (Page et al. 2003).

Ecology & Life History

Basic Description: A small fish (darter).
Reproduction Comments: Males guards eggs.
Habitat Type: Freshwater
Non-Migrant: N
Locally Migrant: N
Long Distance Migrant: N
Riverine Habitat(s): CREEK, MEDIUM RIVER, Moderate gradient, Pool, Riffle
Special Habitat Factors: Benthic
Habitat Comments: Habitat includes rocky pools of headwaters, creeks, and small to medium rivers (Page and Burr 2011); small bedrock creeks (under flat rocks), gravel bottom pools and gentle riffles of larger streams; in larger streams, these darters are often associated with emergent vegetation or occur under tree roots or undercut banks; also in slower riffles and gravel pools with no cover. Eggs are laid on the underside of large stones (Page 1983).
Adult Food Habits: Invertivore
Immature Food Habits: Invertivore
Length: 7 centimeters

Population/Occurrence Delineation

Group Name: Darters

Use Class: Not applicable
Minimum Criteria for an Occurrence: Occurrences are based on evidence of historical presence, or current and likely recurring presence, at a given location. Such evidence minimally includes collection or reliable observation and documentation of one or more individuals (including eggs and larvae) in appropriate habitat.
Separation Barriers: Dam lacking a suitable fishway; high waterfall; upland habitat.
Separation Distance for Unsuitable Habitat: 10 km
Separation Distance for Suitable Habitat: 10 km
Separation Justification: Data on dispersal and other movements generally are not available. Though larvae of some species may drift with the current, Turner (2001) found no significant relationship between a larval transport index and gene flow among several different darter species.

Separation distances are arbitrary but reflect the likely low probability that two occupied locations separated by less than several kilometers of aquatic habitat would represent truly independent populations.

Because of the difficulty in defining suitable versus unsuitable habitat, especially with respect to dispersal, and to simplify the delineation of occurrences, a single separation distance is used regardless of habitat quality.

Occupied locations that are separated by a gap of 10 km or more of any aquatic habitat that is not known to be occupied generally represent different occurrences. However, it is important to evaluate seasonal changes in habitat to ensure that an occupied habitat occurrence for a particular population does not artificially separate spawning areas and nonspawning areas as different occurrences simply because there have been no collections/observations in an intervening area that may exceed the separation distance.
