The wood frog (Lithobates sylvaticus or Rana sylvatica[2]) has a broad distribution over North America, extending from the boreal forest of the north to the southern Appalachians, with several notable disjunct populations including lowland eastern North Carolina. The lifespan of a wood frog can be up to 10 years. The name ‘frog’ is often used to distinguish the smooth-skinned, leaping anurans from the squat, warty, hopping ones, which are called toads. Common Name: Wood Frog, robber’s mask frog – Named for its habitat. [19][20] During the first stage, the larvae are adapted for rapid development, and their growth depends on the temperature of the water and has a higher mortality rate. Rate! v + 732 pp. Thus, conservation of this species requires a landscape (multiple habitats at appropriate spatial scales) perspective. Characteristics and Adaptedness of Feeding Behaviors of North American Anurans, Paper presented at June 1973 meetings of the Animal Behavior Society, Amherst, MA, CS1 maint: multiple names: authors list (, 10.2305/IUCN.UK.2015-4.RLTS.T58728A78907321.en, "Spatiotemporal diversification of the true frogs (genus, 10.1890/0012-9658(1997)078[2279:EEOFWC]2.0.CO;2, "Survival mechanisms of vertebrate ectotherms at subfreezing temperatures: applications in cryomedicine", "Low temperature molecular adaptation of the skeletal muscle sarco(endo)plasmic reticulum Ca, 10.1670/0022-1511(2006)40[442:CPFASW]2.0.CO;2, 10.1670/0022-1511(2003)037[0390:thuawd]2.0.co;2, Animal Diversity Web – University of Michigan Museum of Zoology, Photographs, video and audio recording of breeding Wood Frogs, https://en.wikipedia.org/w/index.php?title=Wood_frog&oldid=1002782727, Creative Commons Attribution-ShareAlike License, Geographic range of the wood frog in North America (in blue), This page was last edited on 26 January 2021, at 01:09.

Wood Frogs may also have pronounced dark bars on the rear legs, a small amount of black mottling on the sides and a light-coloured stripe down the back. Glycogen is the form in which glucose is stored in the liver. [14][15], Frogs can survive many freeze/thaw events during winter if no more than about 65% of the total body water freezes. No. Acris crepitans, Northern cricket frog and subspecies (Pictures needed). Answered What is the scientific name of the Siberian wood frog? The wood frog has garnered attention by biologists over the last century because of its freeze tolerance, relatively great degree of terrestrialism (for a ranid), interesting habitat associations (peat bogs, vernal pools, uplands), and relatively long-range movements. [1], The wood frog has a complex lifecycle that depends on multiple habitats, damp lowlands, and adjacent woodlands. The mechanism that allows for this phenomenon has been subject to scientific inquiry in the field of cryobiology for over a century. Wood Frog:(Lithobates sylvaticus or Rana sylvatica) uses disruptive coloration including black eye markings similar to voids between leaves, bands of the dorsal skin (dorsolateral dermal plica) similar to a leaf midrib as well as stains, spots & leg stripes similar to fallen leaf features. These standardized codes are used to abbreviate the scientific name of each animal. Some may remain in moist areas to overwinter. Large and athletic, … Wood frogs are forest-dwelling organisms that breed primarily in ephemeral, freshwater wetlands: woodland vernal pools. A taxonomic and geographical reference. Acris gryllus, Southern cricket frog and subspecies. It is brown, rusty red, gray, or tan, and it has bumpy skin. It is a small animal, approximately 1.4 to 3.25 inches long. It has a yellow to greenish white belly and a light stripe on its upper lip. The level of glucose released by this process is about 4500 mg/100ml of blood. Wood frogs breed very early in the spring after they thaw out (a process not yet well understood), the males announcing the process with a call that has been characterized as a duck-like quacking sound. The common name of the Wood Frog is pretty obvious, it's a frog that is found mainly in wooded areas. The scientific name of a wood frog is Lithobates sylvaticus and it is from the family Ranidae, the family of true frogs. Wood frog, (Rana sylvatica), terrestrial frog (family Ranidae) of forests and woodlands. The discovery that wood frogs freeze in the winter is attributed to William Schmid, a physiologist at the University of Minnesota. Anaxyrus americanus, American toad and subspecies. [20][21] The second stage of development features rapid development and growth, and depends on environmental factors including food availability, temperature, and population density. The background color varies from grey brown to dark brown or reddish brown. Ice formation lowers the water content in this intracellular region. The average body length is about 40-60 mm. The first evasive leap is fast and long. The feeding pattern of the wood frog, basically similar to that of other ranids, is triggered by prey movement and consists of a bodily lunge that terminates with the mouth opening and an extension of the tongue onto the prey. The scientific name derives as follows: Lithobates (from Greek) - meaning a stone (Litho) that walks or haunts (bates), sylvaticus(from Latin) - pertaining to woods or forests. His subsequent studies on the subject led to a seminal article in the journal Science entitled “Survival of Frogs in Low Temperatures.”. This mass will generally be deposited in the deepest part of the pond. Glucose is the primary energy source for the cells that make up body tissue and the major nutrient for brain cells. Similar to other northern frogs that enter dormancy close to the surface in soil and/or leaf litter, wood frogs can tolerate the freezing of their blood and other tissues. By contrast, humans are diagnosed with diabetes when the level reaches about 300 mg/100ml. The tree frog has two scientific names: Lithobates sylvaticus and Rana sylvatica. Its most recognizable feature is the black mask on its face that is often called a "robber's mask." Wood frogs inhabit a wide variety of habitats including tundra, thickets, wet meadows, bogs, coniferous and deciduous forests. It's a small animal that is around 1.4 to 3.25 inches in length. Identification: A medium-size, rich brown to fawn colored frog with a dark black mask around the eye. [11] A more extensive amount of tongue surface is applied in the feeding strikes of these other frog species, with the result that usually the prey is engulfed by the fleshy tongue and considerable tongue surface contacts the surrounding substrate. Its population density through large areas reaches several hundred or thousands individuals per hectare. Another conservation concern is that wood frogs are primarily dependent on smaller, "geographically isolated" wetlands for breeding. [17][19][22] The success of the larvae and tadpoles is important in populations of wood frogs because they affect the gene flow and genetic variation of the following generations. Scientific name: Pseudacris nigrita. Common Name: Wood Frog, robber’s mask frog – Named for its habitat. At this point in the feeding strike, the wood frog differs markedly from more aquatic Lithobates species, such as the green frog, leopard frog, and bullfrog. Wood frogs are wonders of natural science. Join now. Their main distinguishing feature is a black band that extends from the front of the mouth to the base of the front leg. There is a dark line in front of each eye and a dark spot on the back. [4][5] Adult wood frogs are usually brown, tan, or rust-colored, and usually have a dark eye mask. The Wood Frog. : Thompson, Kootenay, Cariboo, Skeena, Omineca, Peace, Okanagan. It is the most abundant frog species in Alaska. Having found a frozen wood frog, he surmised that it was not because it erred in not having dug deep enough to escape the cold (a practice of many other amphibians), but was rather intentional, as he proved on reviving it. The majority of offspring are philopatric, returning to their natal pool to breed. [5][17] Females deposit eggs attached to submerged substrate, typically vegetation or downed branches. The contiguous wood frog range is from northern Georgia and northeastern Canada in the east to Alaska and southern British Columbia in the west. Breeding occurs from February till late March in forested pools. Therefore, the cells don’t freeze, but the surrounding areas do. [19] Most frogs breed only once in their lives, although some will breed two or three times, generally with differences according to age. A small brown frog with a dark eye mask in the woods is likely to be a wood frog. It is also found in the Medicine Bow National Forest. Close observation will often glimpse a second short dive under the leaf litter, making the frog seem to disappear. They are shy and nocturnal, so they’re difficult to find, but their unusual chirping call is recognizable at night in their favorite habitats. Scientific Names of Plants, A-B . Scientific name: Lithobates sphenocephalus (or Rana sphenocephala) These are some of the most abundant frogs in Florida and are usually found in and around shallow bodies of water. [19], Although the wood frog is not endangered or threatened, in many parts of its range urbanization is fragmenting populations. It is this characteristic feature that is responsible for the sobriquet “robber’s mask” frog. The first two come from figures out of Greek mythology. Appearance. [20], Following metamorphosis, a small percentage (less than 20%) of juveniles will disperse, permanently leaving the vicinity of their natal pools. They breed in wetlands, lakes, and stream backwaters, and overwinter under fallen leaves on the forest floor. This would result in severe dehydration were it not for the glucose, which restores the osmotic balance and acts like a form of antifreeze. The wood frog is around 3 inches in length. When the epinephrine in the bloodstream circulates to the liver, it triggers the conversion of glycogen to glucose (to provide more energy in the “fight or flight” glandular response). Lithobates sylvaticus, Wood Frog [English] Author(s)/Editor(s): ... Article/Chapter Title: Scientific and Standard English Names of Amphibians and Reptiles of North America North of Mexico, with Comments Regarding Confidence in Our Understanding, Eighth Ed. They can be found under logs and rocks far from water, or in ponds. In the feeding strike, the tongue is swung forward as though on a hinge, so some portion of the normally dorsal and posterior tongue surface makes contact with the prey. Potpourri: Wood frogs range from Georgia to northern Canada and Alaska. They are true frogs and have a classic frog shape, and are marked with dark ‘leopard spots’ and a pair of light colored ridges down their backs. It has well-defined dorssolateral folds.
