The Illinois chorus frog (Pseudacris illinoensis) is a species of chorus frog that lives in scattered, restricted habitat ecosystems in the states of Arkansas, Illinois, and Missouri. It was published by Smith in 1951. Its life cycle is little known, its isolated populations are increasingly restricted by agricultural drainage, and it is listed as a threatened subspecies. [2] It is often referred to as a subspecies of P. streckeri . Collins [3] recognized it as its own species which was followed by ASW6.0 [4] and Amphibiaweb [5] on the basis of its diagnosability from Pseudacris streckeri and its allopatry. The IUCNredlist 2013.2 has not incorporated this taxonomic split. [6]
The Illinois chorus frog, a wetland amphibian, grows to a maximum length of 1.5 inches (3.8 cm). Its range is restricted to isolated sandy wetlands along the banks of the Mississippi River and a major tributary, the Illinois River. [2]
Its life cycle begins with the mating season beginning in late February and continuing until late April, when the small amphibian signals its aptitude with a version of the distinctive cry that gives its genus its name.[ citation needed ] The breeding call can be heard at a distance of up to 1 mile (1.6 km).[ citation needed ] The pools of spring meltwater, where they live and eat, begin to dry up as early as mid-May, and the frogs disappear into hibernation below the winter frost line.[ citation needed ] With unusually strong forelegs for its size, the Illinois chorus frog is described as the only frog that uses a breast stroke motion to dig its sandy burrows. [2]
The Illinois chorus frogs' preferred habitat in Arkansas includes the patch of sandy wetland soil surrounding Stuttgart, Arkansas where rice is grown. However, the invention of laser land-levelling, and its use by rice paddy operators, has eliminated 61% of the subspecies' range in this southern state. [2]
The Illinois Department of Natural Resources carried out a field study of the Illinois chorus frog's habitat in Mason County, Illinois, in March 2011. The study hoped to develop a methodological protocol to monitor the Illinois chorus frog's threatened population. [7]
The ornate chorus frog is a species of chorus frog endemic to the Southeastern United States. Their distribution ranges from North Carolina, east to the very eastern part of Louisiana, and south to northern parts of Florida.
The spring peeper is a small chorus frog widespread throughout the eastern United States and Canada. They prefer permanent ponds due to their advantage in avoiding predation; however, they are very adaptable with respect to the habitat they can live in. In northern regions, the frog is able to endure below freezing temperatures due to the capacity of their livers to exude and flush the bloodstream with a glucose cryoprotectant which acts both as an anti-freeze in their blood, and allows organs like the heart to enter into a state of protected dormancy. They are so called because of their chirping call that marks the beginning of spring. Crucifer is derived from the Latin root meaning "cross-bearing." This could be a reference to the cross-like pattern on the spring peeper's dorsal side.
The California red-legged frog is a species of frog found in California (USA) and northern Baja California (Mexico). It was formerly considered a subspecies of the northern red-legged frog. The frog is an IUCN near-threatened species as of 2021, has a NatureServe conservation status of Imperiled as of 2015, and is a federally listed threatened species of the United States that is protected by law.
The boreal chorus frog is a species of chorus frog native to Canada from central Quebec to eastern British Columbia and north to the Northwest Territories and the southern portion of the Yukon. It occurs in the USA throughout Montana, northwestern Wisconsin, northeastern Arizona, northern New Mexico, and southwestern Utah.
The spotted chorus frog or Clark's tree frog is a small, nocturnal chorus frog native to the grasslands and prairies of the central United States and Tamaulipas, Mexico.
The western chorus frog, also known as striped chorus frog, or midland chorus frog is a species of frog found in Canada and the United States.
Strecker's chorus frog is a species of nocturnal tree frog native to the south central United States, from southern Kansas, through Oklahoma and east to Arkansas, the northwestern tip of Louisiana and south throughout much of Texas.
The upland chorus frog is a species of chorus frog found in the United States. It was recently separated from the Western chorus frog,, being identified as an individual species rather than a subspecies. They are a rarely seen species, but their calls are frequently heard soon after rains in the spring time.
The little grass frog is a species of chorus frog endemic to the Southeastern United States. It is currently the smallest North American anuran and occurs in a wide variety of ephemeral and semi-permanent wetlands.
The crawfish frog is a medium-sized species of frog native to the prairies and grasslands of the central United States. It gets its name because it inhabits the burrows of crayfish for most of the year. They have defined golden or black circles all over their body.
The Appalachianmountain chorus frog, formerly known as just the mountain chorus frog, is a species of frog in the family Hylidae. The species is endemic to the United States. The natural habitats of P. brachyphona are temperate forests, rivers, intermittent rivers, swamps, freshwater marshes, intermittent freshwater marshes, freshwater springs, ponds, open excavations, and canals and ditches. It is threatened by habitat loss.
Brimley's chorus frog is a species of frog in the family Hylidae. It is endemic to the United States and is named for North Carolina zoologist C.S. Brimley.
The southern chorus frog is a species of frog in the family Hylidae, endemic to the southeastern United States. Its natural habitats are temperate forests, temperate grassland, shrub-dominated wetlands, swamps, freshwater marshes, intermittent freshwater marshes, ponds, open excavations, seasonally flooded agricultural land, and canals and ditches. It is threatened by habitat loss.
Rose's rain frog or Rose's rainfrog is a species of frog in the family Brevicipitidae. It is endemic to the sandveld of south-western coastal South Africa. It is less-frequently known as Rose's short-headed frog, Rose's Blaasop, or the sand rain frog. Some treat Breviceps fasciatus as a synonym of this species, although other authorities have expressed doubt.
Pseudacris fouquettei is a species of chorus frog found in the south-eastern United States. It was recently separated from similar species, Pseudacris feriarum.
Pseudacris kalmi, the New Jersey chorus frog, is a species of frog in the treefrog family Hylidae. It is found in the states near New Jersey in the United States. It was first described as subspecies of Pseudacris triseriata but it is differentiated by range and size. This frog's color ranges from grey to tan or greenish brown with a dark stripe on both sides of the body that extends from the snout, through their eyes, and to the groin. It breeds in early spring from February to April. It broods in shallow bodies of water, especially vernal pools, which dry up later in the season.
Acrisinae is a subfamily of the tree frog family Hylidae. There are only two genera in this subfamily, Acris and Pseudacris. They are native to most of the Nearctic realm, and are found as far north as the Great Slave Lake in Canada, all across the United States, and down Baja California and some parts of northern Mexico. One species, the pacific tree frog, has been introduced to several locations outside its range, and it is possible that other species may have been as well.
