Distribution and Habitat

Ambohitantely, An’Ala, Andasibe, Anjanaharibe, Ankeniheny, Besariaka near Moramanga, Fierenana, Mandraka, Manombo, Ranomafana, Sainte Luce, Vevembe, Vohiparara. Occurs from 800-1,200m asl (IUCN 2008). Often in relatively large and rather exposed swamps at the forest edge, but also in small puddles in forest. Often in shallow flooded waters with dense fern vegetation.

Life History, Abundance, Activity, and Special Behaviors

provided by AmphibiaWeb articles
Habits: Calling males were heard during day and night in swamps and shallow pools, sitting in low vegetation (20-50 cm high) above the water, often underneath leaves. Males sometimes form enormous explosive choruses after heavy rains. Mating behaviour was seen at Andasibe and is similar to B. wittei. When the leaf is narrow, the male's hands attach to the underside of the leaf. This position can be mistaken with head clasping.Call: A call consists of 2-3 unharmonious, intense chirping notes. We never heard long note series as in B. wittei. Frequency is between 4 and 7 kHz. Eggs and tadpoles: Egg masses at Andasibe were attached ca. 0.7 m above water surface on leaves. Tadpoles complete their development in the swamps. Tadpoles from Andasibe assigned to this species measure 7-10 mm total length in stage 25, 24-28 mm in stages 39-41. Tooth formula is 1/5+5//3, sometimes 1/4+4//3. Young measure 8-10 mm body length (Blommers-Schlösser 1979).

Blommersia blommersae

provided by wikipedia EN

Blommersia blommersae is a species of frog in the family Mantellidae. It is endemic to east-central Madagascar.[1][3][4][5] Both the generic and specific names honour Rose Marie Antoinette Blommers-Schlösser, a Dutch herpetologist and entomologist[6] who collected the type series.[2] Common name Moramanga Madagascar frog has been proposed for it.[1][3][6]

Description

Blommersia blommersae is a small frog that can grow to 22 mm (0.9 in) in snout–vent length. The overall appearance is slender.[2] The fingers have no webbing whereas the toes are webbed. The colouration is variable:[5] the dorsum is gray or light brown with darker, irregular spots, forming an inter-ocular bar and a V-shaped pattern on the scapular region. The canthal and tympanic regions are brown. The upper lip is white. The lower surfaces are irregularly speckled with dark, especially on the throat and chest.[2]

The male advertisement call is a series of 2–3 chirps lasting about 70–150 ms.[7]

Tadpoles in Gosner stage 25 measure 7–10 mm (0.3–0.4 in) and in stages 39–41 24–28 mm (0.9–1.1 in) in total length.[5]

Habitat and conservation

Blommersia blommersae occurs in swamps in or near forest at elevations of 800–1,780 m (2,620–5,840 ft) above sea level. It can occur in degraded habitats when swamps are present, but not in agricultural areas. Males often call from low vegetation. Breeding takes place in swamps; the eggs are laid on leaves above water. It is a locally very abundant species. It is suffering from the loss of forest habitats. It is known from one reserve near the Andasibe-Mantadia National Park and from the Ranomafana National Park.[1]
