Concept Reference Code: B91ROB01NAUS
Name Used in Concept Reference: Etheostoma crossopterum
Taxonomic Comments: Subgenus CATONOTUS. The original description of E. CROSSOPTERUM (Braasch and Mayden 1985) was based on collections that included specimens that were reidentified/described by Page et al. (1992) as E. NIGRIPINNE, E. CORONA, E. FORBESI, and E. PSEUDOVULATUM; in addition, two INHS specimens listed as E. CROSSOPTERUM by Braasch and Mayden were reidentifed by Page et al. (1992) as LUXILIS CHRYSOCEPHALUS and NOTROPIS HETEROLEPIS.

NatureServe Global Conservation Status Factors

Range Extent: 20,000-200,000 square km (about 8000-80,000 square miles)
Range Extent Comments: Range includes the middle and lower Cumberland River drainage, Kentucky and Tennessee (mostly below Caney fork but occurs in Obey River system and Barren Fork Collins River); middle Duck River system, including upper Buffalo River, Tennessee; Shoal Creek system (Tennessee River drainage, Tennessee and Alabama); and tributaries to the Mississippi River in western Tennessee (Reelfoot Lake, Bear Creek) and southern Illinois (Cache River (Page and Burr 2011).

Number of Occurrences: 21 - 300
Number of Occurrences Comments: This species is represented by a large number of occurrences (subpopulations).

Population Size Comments: Total adult population size is unknown but apparently quite large (likely greater than 100,000). This darter is common throughout much of its range (Page et al. 1992); locally abundant (Page and Burr 2011).

Overall Threat Impact Comments: No major threats are known.

Short-term Trend: Relatively Stable (<=10% change)
Short-term Trend Comments: Trend over the past 10 years or three generations is uncertain but likely relatively stable.

Reproduction Comments: Age range of breeding females is 1-3 years (Bart and Page 1992).
Habitat Type: Freshwater
Non-Migrant: Y
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 and adjacent riffles of headwaters and creeks (Page and Burr 2011). This darter prefers small quiet streams with large flat rocks or bedrock bottoms; small populations occur in small gravelly streams and in larger streams along quiet margins and beneath undercut banks (Braasch and Mayden 1985). Spawning occurs in cavities under rocks; females attach eggs to undersides of stones (Braasch and Mayden 1985).

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.
