Raorchestes griet
Template:Short description Template:Use dmy dates Template:Use Indian English Template:Speciesbox
Raorchestes griet is a species of frog in the family Rhacophoridae. It is endemic to the Western Ghats south of the Palghat Gap in Kerala and Tamil Nadu states, India. The specific name griet honours Griet Decock, spouse of Template:Interlanguage link multi, the scientist who described the species.[1][2] The common name Griet bush frog has been coined for it.[3][2]
Description
Adult males measure Script error: No such module "convert".[1][4] and adult females, based on a single specimen, Script error: No such module "convert". in snout–vent length.[4] The snout is rounded. The tympanum is indistinct, but the supratympanic fold is prominent. The fingers have well-developed discs and dermal fringes but no webbing. The toes have discs and rudimentary webbing. Skin of snout bears small horny spines, and there are horny ridges between eyes, arranged in triangle. Dorsal skin is covered with small horny spines.[1] The dorsum is light greyish brown, light brownish grey, or light-reddish brown. Dark or light red markings may be present.[4]
Habitat and conservation
Raorchestes griet has been observed in roadside vegetation near isolated forest patches or in plantations near forests at about Script error: No such module "convert". above sea level.[5][4] It is nocturnal[4] and arboreal, which leaves it endangered by logging. Males call from ground level up to two metres above the ground.[4] It has been observed on eucalyptus trees, but scientists do not think the frogs can live on commercial eucalyptus plantings as other frogs can.[6]
This species can be locally abundant, but it is threatened by habitat fragmentation associated with deforestation. Visitors may also disturb this frog during annual pilgrimages to the Western Ghats. Scientists have observed that the fungus Batrachochytrium dendrobatidis can infect other frogs in Raorchestes, so they infer the fungal disease chytridiomycosis may also infect R. griet. Scientists also name climate change as a threat to this frog.[5]
The frog's range includes several protected parks.Meghamalai Wildlife Sanctuary, Eravikulam National Park, Kodaikanal Wildlife Sanctuary, Anamalai Tiger Reserve and Periyar Tiger Reserve.[5]
