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]

Description

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]

Threats

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]

Conservation

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]

<span class="mw-page-title-main">Spring peeper</span> Species of amphibian

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.

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.
