Distribution

Hypogean populations have been found in five large base level caves and six resurgenses in Perry County, Missouri, USA (37o35’N, 90o05’W). These are in two separate karst basins: Mystery-Rimstone Karst (MRK in the Table) to the east of the surface river called Cinque Hommes Creak, and Central Perryville Karst (CPK in the Table) to the west of the river. The extensive Mystery Cave may contain up to 2000 individuals (Burr, Adams, Krejca, Paul and Warren 2001). Troglomorphic individuals have also been collected in epigean waters of eight rivers in the region, presumably after leaving the caves via the resurgences. In the Table below the two letter abbreviations are to assist in interpretation of the Tables and Figures in Day et al. (2014).

Elliott (2007) says of the Perryville karst "Some of the densest known karst development in the USA occurs in Perry County, in limestones of middle Ordovician age or older. About 700 cave entrances are recorded in the large sinkhole plain, with many large river caves, such as Crevice Cave, the longest in Missouri at 45 km. Large stream caves are especially developed in the Cinque Hommes Creek area. The uplands are covered with up to 10 m of loess derived from the Mississippi River flood plain (Vandike, 1985), and there is heavy row crop agriculture. Biologically similar to the Jefferson-Ste. Genevieve Karst, the Perryville Karst has its own endemics and lacks trechine beetles. Endemic species include Sphalloplana evaginata, Perryville cave planarian, Kenkia lewisi, Lewis’ cave planarian, and Cottus [specus] ... Grotto sculpin (Burr et al., 2001), now on Missouri’s Species of Concern List. Mystery Cave ranks as third in cave biodiversity in Missouri. With 18 troglobites, this karst has high area endemism."

Habitat

Grotto Sculpin live in running water in base level streams. They are found in pools and riffles and over a variety of substrates (Burr, Adams, Krejca, Paul and Warren 2001).

Systematics

Rewrite all of this

There are remarkable differences between Grotto Sculpin and surface C. carolinea. They show apparent cave modifications including: reduced pigment, reduced eye size, reduced number of pelvic fin rays, a gap between the dorsal fins, a modified cephalic lateral line system and a longer caudal peduncle. Burr, Warren and Paul (1992), Paul, Burr and Warren (1993) and Burr, Adams, Krejca, Paul and Warren (2001) analysed 10 meristic and 28 morphometric variables in epigean and hypogean specimens. A Principal Component Analysis showed there to be a total separation of the epi- and hypogean populations in eye length vs. standard length, pelvic fin ray number and details of the cephalic lateral line system. It seems possible that this is an example of a troglophile/troglobite transition.

Biological Notes

Through the work of Brooks Burr and his students at Southern Illinois University, beginning in the early 1990s, continued by Ginny Adams and her students at the University of Central Arkansas, and more recently by John Schiebe and his students at Southeast Missouri State University, a considerable amount is known about numerous aspects of the biology of this species. The following is a selection of publications which will provide a well-rounded introduction to what is known.

Peck and Lewis (1977) A comprehensive account of the invertebrates which inhabit the caves containing Cottus specus.

Vandike (1985) Descibes the hydrogeology of the Perriville karst area.

Walsh (1988), Walsh (1989), Walsh (1995) These three sources describe in detail two of the main caves in which Cottus specus is found: Mystery cave and Rimstone River Cave.

Gardner (1986) Describes the invertebrates found in Missouri caves and springs, therefore of direct ecological relevance.

Burr, Warren and Paul (1992), Paul, Burr and Warren (1993), Krejca, Burr, Warren and Paul (1994), Krejca, Burr, Paul and Warren (1994). These four publications were all short abstracts for various conferences and I have not been able to obtain any of them to see what they said.

Paul (1994) A thesis describing aspects of cave adaptation.

Krejca (1994) With Walsh (above) the most important source for the caves in which this species is found.

Burr, Adams, Krejca, Paul and Warren (2001) The first comprehesive account of the biology of Grotto Sculpin which was still, at that time, considered as a member of the species Cottus corolinae. This paper and Adams (2005) are the most significant accounts of the overall biology, though some later publications get into more detail about particular parts of the biology.

Brison (2001) A thesis studying experimental analysis of metabolic adaptation in response to photoperiod and food availability.

Adams (2005) This Ph.D. thesis is equally as important for detail as the Burr et al. (2001) paper and should be consulted by anyone with an interest in this species.

Kinziger, Goodman and Studebaker (2007) Shows that there is a great deal of genetic structure within Cottus carolinae, laying the groundwork for the creation of a new species in 2013.

Elliott (2007) A major review of caves, karst, conservation and biogeography in Missouri.

Gerken and Adams (2008) A short paper on habitat use.

Day, Starkey, Adams, Brummett and Keeney (2014) A detailed study of the population genetics and relationships of the various groups of Cottus specus in the karst areas.

Day, Starkey and Gerken (2014) Showed that parasitism by Acanthocephala is worse in hypogean populations than in epigean populations in Missouri. Perhaps because of increased cannibalism in the caves.

Day, Gerken and Adams (2014) Population ecology and seasonal demography

Fernholz and Phelps (2016) A study to determine if PIT tags are suitable for use as individual markers in Cottus specus.

Fernholz (2017) A thesis in two chapters. Chapter 1 is effectively the same as Fernholz and Phelps (2016). Chapter 2 is on habitat selectivity and availability and appears not to have been published otherwise.
