Rana capito (LeConte, 1855)
Carolina Gopher Frog
Subgenus: Pantherana
family: Ranidae
genus: Rana
Species Description: LeConte, J. E. (1855). "Descriptive catalogue of the Ranina of the United States." Proceedings of the Academy of Natural Sciences of Philadelphia 7: 423–431.
Taxonomic Notes: This species was placed in the genus Lithobates by Frost et al. (2006). However, Yuan et al. (2016, Systematic Biology, doi: 10.1093/sysbio/syw055) showed that this action created problems of paraphyly in other genera. Yuan et al. (2016) recognized subgenera within Rana for the major traditional species groups, with Lithobates used as the subgenus for the Rana palmipes group. AmphibiaWeb recommends the optional use of these subgenera to refer to these major species groups, with names written as Rana (Aquarana) catesbeiana, for example.

There are two recognized subspecies of Rana capito, the Carolina gopher frog, Rana capito capito and the Florida gopher frog, R. c. aesopus. (Rana sevosa used to be a subspecies of R. capito, R. c. sevosa, but has recently been elevated to species status (Young and Crother, 2001) Rana capito capito ranges in size from 2.5 to 3.5 inches and has a variable color pattern ranging from dark gray to brown spotted with black, reddish brown or dark brown (Conant and Collins, 1991). Warts are always prominent, variable in shape and almost pavement-like and the ventral surface is heavily marked with dark flecks (Conant and Collins, 1991). Rana capito aesopus ranges in size from 2.75 to 3.75 inches and has a color pattern that varies from creamy white to brown through yellowish or purplish (Conant and Collins, 1991). The back may be smooth or slightly warty with black or dark brown irregular markings. The chin and throat is usually spotted but the belly is usually unmarked posteriorly (Conant and Collins, 1991). Males may have yellow on the dorsolateral ridges, on the warts, along upper jaw, and in armpits and groins (Conant and Collins, 1991) and females have longer snout vent lengths than males (Greenberg, 2001). Their voice has been characterized by a deep roaring snore. Large choruses produce an effect like that of pounding surf (Conant and Collins, 1991).

The geographic range of R. capito, prior to the elevation of the subspecies R. sevosa, extended from extreme southeastern Louisiana along the Gulf coast to throughout the upper three-fourths of the Florida peninsula and north along the Atlantic coast to southeastern North Carolina (Young and Crother, 2001). Now it is assumed that the Louisiana, Mississippi and western Alabama populations were all R. sevosa. The Carolina subspecies, R. c. capito, occurs throughout the coastal plain of the Carolinas and is scattered throughout the southeast part of Georgia (Conant and Collins, 1991). The Florida subspecies, R. c. aesopus, occurs along the coastal plains of South Georgia and three-fourths of the Florida peninsula, with isolated populations in west-central Georgia (Conant and Collins 1991).

This species can be found in a wide range of habitats from dry, upland xeric oak scrub, and oak hammocks to pine flat wood forests. Preferred breeding habitats include seasonally flooded, grassy ponds and cypress heads that lack fish populations. In Florida, this species is closely associated with gopher tortoise burrows, particularly in xeric longleaf pin-wiregrass uplands that are within about 1.7km of suitable breeding ponds (Schmalzer et al., 1999).

Life History, Abundance, Activity, and Special Behaviors
Throughout its range, R. capito is a commensal with the gopher tortoise (Gopherus polyphemus), hence the common name gopher frog, and is almost entirely dependent on G. polyphemus for shelter and to some extent food (Franz, 1988). However, it occasionally occupies a variety of other retreats including the burrows of rodents and crayfish, as well as stump holes and other crevices (Conant and Collins, 1991). Rana capito is the most frequently observed tortoise burrow commensal (Kent et al., 1997). It is generally nocturnal and emerges to sit near the mouth of its burrow to feed on invertebrates and anurans, including toads (Godley, 1992). This regular foraging activity creates a distinct resting area, also called a ‘platform’, outside each frog’s burrow where the soil has been cleared of vegetation and smoothed by the frog’s constant use (Stevenson and Dyer, 2002).

From a few studies scattered throughout its range, it appears that the timing of breeding and larval development varies from shorter breeding and larval periods farther north to multiple breeding episodes and longer larval periods farther south (Bailey, 1991; Semlitsch et al., 1995; Palis, 1998; Greenberg, 2001). In the Atlantic coastal plains of the Savannah River Site in South Carolina at the very edge of their range, Semlitsch et al. (1995), found that the breeding season in some years lasted only a few days and varied in timing between January and April. Palis (1998), who studied their breeding biology in western Florida, reported an eight-month breeding season (October through May) that encompassed three major breeding events (one each in October, February, and April). Reports of larval developmental periods range from 87-113 days in South Carolina (Semlitsch et al., 1995), 141-155 days in laboratory-reared tadpoles (Volpe, 1958) and 210 days in the Florida panhandle (Palis, 1998). Most studies report May through July as the peak emergence time for metamorphic juveniles. Semlitsch et al. (1995) rarely found metamorphs in pitfall traps and the few metamorphs that were seen were caught in drift fences between 27 May and 12 July. Greenberg (2001) found that, in Marion and Putnam Counties, Florida, most emigration of metamorphic juveniles occurred within a 14-86 day period between May and October. Rainfall did not appear to trigger emigration and had a negligible influence on daily emigration rates.

Greenberg (2001) followed the movement patterns of a population of R. c. aesopus in eight isolated ephemeral ponds in longleaf pine-wiregrass sandhills of the Ocala National Forest, Marion and Putnam Counties, Florida, using intermittent drift fences from February 1994 to January 1998. Four of the ponds were located within fire-suppressed sandhills having high densities of laurel oak, other hardwood species and sand pine and the other four ponds were located within regularly burned, savanna-like longleaf pine-wiregrass sandhills. During Greenberg's study, metamorph capture was significantly higher than adult capture. Greenberg observed more juveniles exiting the ponds than entering the ponds (72.8% as apposed to 27.2%). Recruitment was extremely variable between ponds and between years with no obvious correlation with pond hydroperiod. Adult recruitment into ponds did not correspond with upland habitat type; however, juvenile recruitment was consistently higher for ponds within the savanna-like uplands than for ponds within the fire suppressed hardwood-invaded uplands, although it was not obvious why recruitment at these sites was higher.

Trends and Threats
Florida and Alabama have classified R. capito as threatened. Surveys of herpetofauna throughout its range have listed it as uncommon, rare or endangered for at least two decades. Populations are thought to be declining from wetland habitat loss by drainage, filling, or stocking of fish, and upland habitat loss through development, fragmentation and fire suppression (Bailey, 1991). Fire suppression has been linked to population declines because it reduces habitat quality for G. polyphemus. If fire is suppressed, wiregrass and herbaceous vegetative cover (which is preferred by G. polyphemus) declines from increased shading by invading hardwoods. Fire suppression could also affect habitat quality of breeding ponds. For example, changes in hardwood densities could change water chemistry and pond hydrology by increasing transpiration. Greenberg (2001) found that adult recruitment into ponds did not correspond with upland habitat type (fire suppressed or control burned); however, juvenile recruitment was consistently higher for ponds within the savanna-like uplands than for ponds within the fire suppressed hardwood-invaded uplands. Palis (1998) reported high adult usage and egg mass deposition at a pond within a fire-suppressed, longleaf pine-turkey oak sandhill upland but most adults immigrated into the pond from the direction of an early successional hardwood-invaded sandhill, suggesting heavier use of the more open habitat by adult frogs.

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Disturbance or death from vehicular traffic
Secondary succession
Habitat fragmentation
Predators (natural or introduced)

Rana capito was first described as a distinct species by LeConte (1855) but then placed with the crayfish frog Rana areolata by Cope (1875). Collins (1990) resurrected R. capito for all populations within the historical range and since then, researchers have either recognized one gopher frog with three subspecies, R. c. capito, R. c. aesopus and R. c. sevosa or they have included all of R. capito as subspecies of Rana areolata, R. a. capito. Young and Crother (2001) have elevated the Mississippi gopher frog, R. c. sevosa, to full species status.
