North American Atlantic Coast Leopard Frog Habitats Are Weedy and Wet

Summary: North American Atlantic coast leopard frog habitats are weedy and wet meadows and marshes within the I-95 corridor from Connecticut through North Carolina.

North American Atlantic coast leopard frog habitats are freshwater, open-canopied, shallow, slow-flowing, weedy and wet meadows and marshes with cattails, maples and reeds within the I-95 corridor from Connecticut through North Carolina.

Atlantic coast leopard frogs bear their common name for biogeographies based in Atlantic coastlines, leopard-like spots on their backs and legs; and Ranidae true-frogs family membership. The common name Kauffeld’s frog and the scientific name Rana kauffeldi (from Latin rāna, “frog” and kauffeldi) commemorate Carl Frederick Kauffeld (April 11, 1911-July 10, 1974). Kauffeld predictions about a pink-bodied, third species in 1936-1937 and dissertation research at Rutgers University in New Jersey in 2008-2014 by Jeremy Feinberg determine scientific designations.

The ranid (from Latin rāna, [“frog”] and Greek ειδής [-“like”] via Latin –idæ) expects wetland complexes of early successional cattails, reeds, shrubs; flooded meadows; and open-canopied marshes.

The Anura (from Greek ἀν-, “not” and οὐρά, “tail” via ανοὐρά) amphibian order member favors March through August, sometimes October and sometimes November as breeding-season months.

Temperatures from 50 to 64.4 degrees Fahrenheit (10 to 18 degrees Celsius galvanize adult females annually gestating 3,000 to 6,000 flat, white, 0.067-inch (1.7-millimeter) diameter eggs. Ephemeral pools, flooded meadows, freshwater wetlands, open-canopied marshes, riverside floodplains, slow-flowing streams and tide-influenced backwaters in fragmented coastal lowlands and uplands then house the egg-hatched tadpoles. Gill-breathing, herbivorous (from Latin herba [“grass”] and vorō [“I devour”] tadpoles inhabit boggy wetlands inimical to northern and southern leopard frog tadpoles 2 to 3 years.

Air, land and water pollution and temperatures outside 59 and 80 degrees Fahrenheit (16 and 27 degrees Celsius) jeopardize North American Atlantic coast leopard frog habitats.

Six- to 9-year life expectancies keep North American Atlantic coastal leopard frogs as fish-like tadpoles until the latter know 2.56- to 3.27-inch (65- to 83-millimeter) lengths.

Dr. Kauffeld looked to Connecticut, New Jersey and New York, northern and southern leopard frogs’ respective coastal limits, as likely lodging an overlapping, pink-bellied, third species. The male manages axillary amplexus (armpit embrace) by maintaining forelimbs behind his mate's front legs while mounted on her back to fertilize dark, sticky eggs externally. Tadpoles need algae, organic debris, plant tissue and suspended matter even though beetles, caterpillars, crickets, flies, mosquitoes, moths, pillbugs, sowbugs, spiders, stinkbugs and worms nourish adults.

North American carpenter frog habitats offer season's coldest temperatures, north to southward, from minus 10 to 10 degrees Fahrenheit (minus 23.33 to minus 12.22 degrees Celsius).

Artificial and natural ditches, lakes, marshes, ponds, sloughs and swamps with bay laurel-dominant, cypress-dominated emergent, floating, submerged, waterside grassy, herbaceous, weedy, woody plants promote green treefrogs.

Calls, genetics and both respectively queue into 484.6-mile- (780-kilometer-) long distribution ranges Delaware, Maryland, North Carolina, Pennsylvania and Virginia; Connecticut; and New Jersey and New York. Adults reveal heads of greater length than width, two circlar tympanic-membraned eardrums 65-plus percent larger than protuberant ee diameters and dorsolateral folds from eyes to hindlimbs. They seem morphologically similar to overlapping northern and southern leopard frog bodies even though their low-pitched, single-pulsed chuck sounds dissimilar to northerners' slow snores and southerners' swift stutters.

North American Atlantic coast leopard frog habitats tender short forelimbs with unwebbed fingers, long rearlimbs with webbed toes, paired vocal sacs behind eardrums, cream-colored abdomens and brown-spotted blue-gray-green-mint bodies.

New Jersey Chorus Frogs: Banded, Clicking, Pale-Lipped, Striped Bodies

Summary: New Jersey chorus frogs abide in hardwood, mixed hardwood-pine forests in eastern North America, from New York through the tri-state Delmarva Peninsula.

New Jersey chorus frogs abide in hardwood, mixed hardwood-pine forests in eastern North America, in the northeastern and southeastern two-thirds of New Jersey and tri-state Delmarva Peninsula in Delaware, Maryland and Virginia.

Extreme southeast Pennsylvania along the northeastern New Jersey border bears New Jersey chorus frog-friendly hardwood and mixed forests with area shallow-water breeding sites and shrub understories. The allied member of the Hylidae (from Greek ύλη, “forest” via Latin Hylas and -ειδής, “-like” via Latin -idae) tree-frog family carries the name Pseudacris kalmi. Francis Harper (Nov. 17, 1886-Nov. 17, 1972) taxonomically dedicated Pseudacris kalmi (from Greek ψευδής, “false” and ἀκρίς “locust”) to Pehr Kalm (March 6, 1716-Nov. 16, 1779).

The Anura (from Greek ἀν-, “not” and οὐρά, “tail” via ανοὐρά) amphibian order member previously entertained subspecies status to upper-coastal plain- and piedmont-existing upland chorus frogs.

New Jersey chorus frog life cycles favor breeding-friendly, fishless, semi-permanent and temporary bogs, ditches, ephemeral and vernal pools, ponds and streams where grassy, sedgy clumps flourish.

January or February through March or April annually guard physically and sexually mature females and males in respective 3- to 4-night and 2- to 3-week groups. Forty-five-millimeter (1.77-inch) diameter masses hold 0.6- to 0.8-millimeter (0.024- to 0.032-inch) diameter ōva (from Latin ōvum, “egg”) cells and 1.2- to 2.0-millimeter (0.057- to 0.079-inch) eggs. One- and 1-plus-year-old, physically and sexually mature females install their 30 to 100 eggs in 8- to 143-egg intervals on the shallow-water stems of aquatic plants.

Batrachochytrium dendrobatidis fungus, fertilizer runoff, globally warmed climate change, nonnative species, toxic pesticides, trematode-induced deformities and ultraviolet radiation jeopardize North American New Jersey chorus frog habitats.

New Jersey chorus frogs know perhaps 2- to 5-year life cycles that knit together 1- to 2-day-long egg and 21- to 28- or 75-day-long tadpole stages.

Gill-breathing, herbivorous (from Latin herba, “grass” and vorō, “I devour”) tadpoles no longer look fish-like when 12- to 14-millimeter (0.47- to 0.55-inch) lengths launch froglet metamorphoses. Predatory aquatic and woodland insects, crayfish, foxes, herons, mink, raccoons, shrews, shrikes, skunks, snakes, spiders and turtles menace New Jersey chorus frogs’ egg, tadpole, frog moments. Ants, beetles, caddisflies, craneflies, crickets, flies, grasshoppers, mites, mosquitoes, moths, pillbugs, sowbugs, spiders, springtails, stinkbugs, termites, wasps and worms nourish adults, not algae-, debris-, diatom-nurtured tadpoles.

North American New Jersey chorus frog habitats offer north-south season-coldest temperatures, Staten Island, New York, through Delmarva, at minus 10 degrees Fahrenheit (minus 23.3 degrees Celsius).

Boggy, bushy, grassy, herbaceous, marshy, shrubby, swampy, weedy, woody wetlands, flooded pastures, grassy floodplains and seasonal ditches, ponds, pools and streams promote New Jersey chorus frogs.

Lang Elliott, Carl Gerhardt and Carlos Davidson quantify 0.75- to 1.25-inch (1.91- to 3.18-centimeter) snout-vent (excrementary opening) lengths in The Frogs and Toads of North America. Adults reveal light-lined upper lips, one dark band through each side's snout, gold-rimmed dark eye and hind-limb and three back-centered dull, irregular or thick, well-defined stripes. Advertisement calls sound like high-inflected, rising-pitched crrreeeeek clicks with pulse trill rates swifter than non-overlapping, similar, slower boreal, cajun, midland, southern and upland chorus frog advertisements.

Cream-bellied brown-gray-green bodies with banded sides, lined lips and striped backs trill throughout Delmarva's and New Jersey's grass-teeming, pine-thronged North American New Jersey chorus frog habitats.

Mountain Chorus Frogs: Dark-Masked Eyes and Brown-Gray-Olive Bodies

Summary: Mountain chorus frogs are in forested, hilly, shallow-watered habitats in the Appalachian-wooded foothills and mountains of 10 southeastern states.

mountain chorus frog (Pseudacris brachyphona): Brad Michael "Bones" Glorioso/USGS National Wetlands Research Center, Public Domain, via USGS Amphibian Research and Monitoring Initiative (ARMI)

Mountain chorus frogs are in forested, hilly, shallow-watered habitats in the Appalachian-wooded southeastern Unitedstatesian foothills and mountains in Alabama, Georgia, Kentucky, Maryland, Mississippi, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia and West Virginia.

Mountain chorus frogs bear their common name for braving and breeding in high, hilly habitats that bring in plains- and piedmont-loving, somewhat overlapping upland chorus frogs. The scientific, species name Pseudacris brachyphona (from Greek ψευδής [“false”], ἀκρίς [“locust”], βραχύς [“brief”] and φωνή [“sound”]) confirms Hylidae tree-frog family and Anura amphibian order memberships. Edward Drinker Cope (July 28, 1840-April 12, 1897) in 1889 described the hylid (from Greek ύλη, “forest” via Latin Hylas and -ειδής, “-like” via Latin -idae).

The anuran (from Greek ἀν-, “not” and οὐρά, “tail” via ανοὐρά) expects forested hills with shallow temporary-flooded fields, roadside ditches and small ponds, pools or streams.

February through April function as breeding season months in mountain chorus frog life cycles that fit with other early spring-breeding hylids such as similar-looking spring peepers.

Mountain chorus frogs go around on long legs with round, small toe tips and small, sticky toe pads more like leaping wood frogs than walking treefrogs. They head for even higher altitudes above sea level than upland chorus frogs, whose overlapping distribution ranges have rare habitat niches in Appalachian foothills and mountains. The male advertisement call is almost identical to the coastal plain, lower altitude-inhabiting, non-overlapping Brimley's chorus frog's and squirrel treefrog's respective rrrack-rrrack-rrrack-rrrack-rrrack and rrraak trilled voices.

Batrachochytrium dendrobatidis fungal disease; fertilizer runoff; global-warmed, ultraviolet-radiated climate change; nonnative species; toxic pesticides; and trematode fluke-induced deformities jeopardize mountain chorus frogs in North American habitats.

Mountain chorus frogs know the nocturnal lifestyles of more secretive, warier upland chorus frogs even as they sometime keep daylight hours along hoppable, moist woodland trails.

One-, one-plus-year old physically and sexually mature female mountain chorus frogs leave 400 eggs in 10- to 50-egg groups on shallow-water, stream-edge ditch, pond, pool vegetation. Gill-breathing, herbivorous (from Latin herba, “grass” and vorō, “I devour”), little fish-like, swimming mountain chorus tadpoles moved out of their eggs four to five days later. Tadpoles need algae, organic debris, plant tissue and suspended matter even as beetles, caterpillars, crickets, flies, mosquitoes, moths, pillbugs, sowbugs, spiders, stinkbugs and worms nourish adults.

North American mountain chorus frog habitats offer season-coldest temperatures, northward to southward, from minus 15 to 15 degrees Fahrenheit (minus 26 to minus 9.4 degrees Celsius).

Mountain chorus tadpoles present average, mature 30-millimeter (1.2-inch) body lengths before they pass into immature phases as mountain chorus froglets with average 8-millimeter (0.3-inch) body lengths.

Lang Elliott, Carl Gerhardt and Carlos Davidson quantify 1- to 1.5-inch (2.54- to 3.81-centimeter) snout-vent (excrementary opening) lengths in The Frogs and Toads of North America. Adult mountain chorus frogs reveal brown, gray-brown-olive bodies with dark-masked, gold-rimmed eyes; white-banded, white-lined upper lips; spring peeper-like backs; yellow leg undersides; and small toe pads. Two advertisement calls per second with upslurred endings sound like harsh, raspy rrrack-rrrack-rrrack-rrrack-rrrack trills similarizing non-overlapping Brimley's chorus frog rrrack-rrrrack-rrrack-rrrack-rrrack and overlapping squirrel treefrog rrraak-rrraak-rrraak-rrraak-rrraak trills.

North American habitats tender Appalachian-thronging, brown-gray-olive-bodied, trill-slurring, white upper-lipped mountain chorus frogs with dark-masked eyes; plain, spring peeper-like broken-striped or marked backs; and yellow under-sided legs.

North American Eastern Cricket Frog Habitats Are Grassy, Open, Shallow

Summary: North American eastern cricket frog habitats are grassy, open, shallow waters from South Dakota south through Mexico and east to New York through Florida.

North American eastern cricket frog habitats are grassy, open, shallow waters from South Dakota southward through Texas and into Mexico and eastward from Atlantic coastal New York through Florida and everywhere between.

North American eastern cricket frogs bear their common name as the eastern-borne, first-named, nominate subspecies Acris crepitans crepitans to the northern cricket frog species Acris crepitans. First-named subspecies and the second-named, Acris crepitans paludicola (from Greek ἀκρίς, [locust] and Latin crepitāns [“rattling”], palūs [“swamp”] and -cola [“inhabitant”]), communicate compactness, sounds and whereabouts. Taxonomic designations of the northern species and its eastern subspecies derive from the scientific descriptions of Spencer Fullerton Baird (Feb. 3, 1823-Aug. 19, 1887) in 1854.

William Leslie Burger (1925-1988), Hobart Muir Smith (Sep. 26, 1912-March 4, 2013) and Philip Wayne Smith (Dec. 2, 1921-Oct. 11, 1986) in 1949 examined paludicola subspecies.

Eastern cricket frogs favor South Dakota, Nebraska, Colorado, Oklahoma, New Mexico, Texas and northeasternmost Mexico eastward even as coastal subspecies favor northeasternmost Texas and southwesternmost Louisiana.

Four-month to 5-year life cycles guard as breeding-season months April through August in grass-edged ditches, marshes and ponds in one northeasternmost Mexican province and 31 states. The Hylidae (from Greek ύλη, “forest” via Latin Hylas and -ειδής, “-like” via Latin -idae) tree-frog family member, without any toe pads, hones 30-foot (9.14-meter) jumps. One- to one-plus-year-old physically and sexually mature females install their 400-egg clutches singly or in 2- to 7-egg intervals on shallow-water floors or shallow-water plant stems.

Batrachochytrium dendrobatidis fungus, fertilizer runoff, globally warmed climate change, nonnative species, toxic pesticides, trematode fluke-induced deformities and ultraviolet radiation jeopardize North American eastern cricket frog habitats.

The Anura (from Greek ἀν-, “not” and οὐρά, “tail” via ανοὐρά) short-bodied, tail-less amphibian order member knows 3- to 4-day hatching times for their spring-summer egg-laying.

North American eastern cricket frogs live as black tail-tipped, fish-like, gill-breathing, herbivorous (from Latin herba, “grass” and vorō, “I devour”) tadpoles for 5 to 7 weeks. They manifest maximum 0.6-inch- (14-millimeter-) long bodies when they metamorphose from swimming tadpoles to leaping, lung-breathing carnivores (from Latin carō, “flesh, meat” and vorō, “I devour”). Tadpoles need algae, organic debris, plant tissue and suspended matter even as such 0.5- to 1.5-inch- (13- to 38-millimeter-) long aquatic insects as mosquitoes nourish adults.

North American eastern cricket frog habitats offer season's coldest temperatures, north to southward, from minus 45 to 40 degrees Fahrenheit (minus 42.8 to 4.4 degrees Celsius).

Black basses (Micropterus spp), bullfrogs (Lithobates/Rana catesbeianus), grackles (Cassidix mexicanus), kestrels (Falco sparverius), garter (Thamnophis sirtalis) and water (Nerodia paucimaculata, Nerodia sipedon) snakes predatorize cricket frogs.

Lang Elliott, Carl Gerhardt and Carlos Davidson quantify 0.625- to 1.625-inch (1.5875- to 4.1275-centimeter) snout-vent (excrementary opening) lengths in The Frogs and Toads of North America. Brown-, gray-, green-, wart-bodied adults reveal one dark triangle between dark eyes; green-, orange-, red-, yellow-striped backs; narrow-, upper-banded thighs with lengthwise-, ragged-, striped rear edges. Advertisement calls sound like striking two small stones into serial gik-gik-gik-gik clicks that speed up and slow down, unlike the steady giik of southern cricket frogs.

North American eastern cricket frog habitats team cricket-like leaps and stone-striking-like clicks with triangle-marked faces; brown-gray-green, warty bodies; large-spotted sides; striped backs and banded, striped thighs.
