Concept Reference Code: A07LEM01NAUS
Name Used in Concept Reference: Pseudacris feriarum
Taxonomic Comments: A molecular phylogeny of Pseudacris based on mtDNA data (Moriarty and Cannatella 2004) revealed four strongly supported clades within Pseudacris: (1) A West Coast Clade containing regilla and cadaverina, (2) a Fat Frog Clade including ornata, streckeri, and illinoensis, (3) a Crucifer Clade consisting of crucifer and ocularis, and (4) a Trilling Frog Clade containing all other Pseudacris. Within the Trilling Frog Clade, brimleyi and brachyphona form the sister group to the Nigrita Clade: nigrita, feriarum, triseriata, kalmi, clarkii, and maculata. The Nigrita Clade shows geographic division into three clades: (1) populations of maculata and triseriata west of the Mississippi River and Canadian populations, (2) southeastern United States populations of feriarum and nigrita, and (3) northeastern United States populations of feriarum, kalmi, and triseriata. Moriarty and Cannatella (2004) found that subspecific epithets for crucifer (crucifer and bartramiana) and nigrita (nigrita and verrucosa) are uninformative, and they therefore discouraged recognition of these subspecies. They concluded that further study is needed to determine if illinoensis warrants status as a distinct species. Molecular data were consistent with retention of regilla, cadaverina, ocularis, and crucifer in the genus Pseudacris.
Using mtDNA samples from a large number of localities throughout North America, Lemmon et al. (2007) elucidated the phylogenetic relationships and established the geographic ranges of the trilling chorus frogs (Pseudacris). They redefined the ranges of several taxa, including P. maculata, P. triseriata, and P. feriarum; found strong evidence for recognizing P. kalmi as a distinct species; and discovered a previously undetected species in the south-central United States (now known as P. fouquettei; Lemmon et al. 2008). Based on mtDNA data, Pseudacris maculata and P. clarkii did not emerge as distinct, monophyletic lineages but, given the degree of morphological and behavioral divergence between the taxa, Lemmon et al. (2007) chose to recognize them as separate species, until further data suggest otherwise.

Ecology & Life History
Locally Migrant: N
Long Distance Migrant: N
Lacustrine Habitat(s): Shallow water
Palustrine Habitat(s): HERBACEOUS WETLAND, Riparian, TEMPORARY POOL
Special Habitat Factors: Benthic, Burrowing in or using soil, Fallen log/debris
Habitat Comments: Habitat includes open and wooded areas such as meadows, moist forests, bottomland swamps, and the vicinity of ponds, bogs, and marshes; this is mainly an upland frog in the north, but it also inhabits lowlands in the south (Conant and Collins 1991). Breeding sites include shallow ponds, flooded woodlands and pastures, and rainwater pools in ditches, fields, and open woods; eggs adhere to sticks and grass (Mount 1975, Redmond and Scott 1996).

Group Name: Hylid Frogs (Treefrogs)
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 larvae or eggs) in or near appropriate habitat where the species is presumed to be established and breeding.
Separation Barriers: Busy major highway such that frogs rarely if ever cross successfully; intensive urban development dominated by buildings and pavement and lacking suitable vegetated frog refuges.
Separation Distance for Unsuitable Habitat: 1 km
Separation Distance for Suitable Habitat: 5 km
Separation Justification: Available information is limited but indicates that hylids generally exhibit limited movements on a short-term basis. In New Jersey, Freda and Morin (1984) and Freda and Gonzalez (1986) demonstrated that individual Hyla andersonii often travel distances of 100 m from breeding ponds during the nonbreeding season. In montane Colorado, Spencer (1964) found that Pseudacris triseriata range into wet meadows usually within about 700 m of their breeding sites and sometimes cross a few hundred meters of upland habitat. Kay (1989) determined that most Pseudacris cadaverina individuals range over small segments of streamcourse; 83 percent of movements were less than 25 m in a 1-year study. In Michigan, nonbreeding home range diameters of Pseudacris crucifer, established around forest debris and vegetation, ranged from 1.2 to 5.5 m (Delzell 1958).
Based on this information it appears that 1 km is an appropriate separation distance for unsuitable habitat. Despite limited data suggesting restricted movements, dispersal data are scant, and these frogs are clearly physically capable of long moves. It seems unlikely that occupied locations separated by a gap of less than several kilometers of suitable habitat would represent independent occurrences over the long term.
Inferred Minimum Extent of Habitat Use (when actual extent is unknown): .5 km
Inferred Minimum Extent Justification: Inferred extent distance pertains to distance from breeding sites.
