Description ( Anglèis )

fornì da AmphibiaWeb articles
First finger hardly extends beyond second; tibiotarsal articulation reaches anterior border of eye or a point between it and the tip of snout. Color: Grayish dorsum, with dark spots, sometimes with reddish and orange suffusion, a light narrow middorsal line is often present. Ventrum white. During the breeding season, the male gular region is black. Tadpole: Medium sized tadpole, Khan (1991a, 1996a) finds no apparent morphological difference from that of Limnonectes limnocharis.For references in the text, see here

Distribution and Habitat ( Anglèis )

fornì da AmphibiaWeb articles
Limnonectes syhadrensis occurs sympatrically in most of its range in Pakistan with Limnonectes limnocharis, which becomes rarer in the lower Indus Valley. L. syhadrensis is widely distributed throughout southern India.

Life History, Abundance, Activity, and Special Behaviors ( Anglèis )

fornì da AmphibiaWeb articles
Limnonectes syhadrensis abounds in paddy fields, marginal vegetation of ponds, puddles and streams in plains. It become rarer in northern hilly tracts along sub-Himalayan ranges. Its call is typical, like the clatter of a typewriter, a loud "Trr, trr, trr, trr, trr", repeated several times. The calling males sit quite apart from each other, away from the water, in the roots of marginal vegetation. Calling is triggered by the first monsoon downpour when water temperature reaches 20o C. Egg diameter ranges from 0.8 to 1.2 mm. Eggs are laid in small batches, embeded in gelatinous material, each enclosed in double jelly capsule. Eggs soon separate and adhere to the grass blades (Khan 1996a).

Zakerana syhadrensis ( Anglèis )

fornì da wikipedia EN

Minervarya syhadrensis, commonly known as long-legged cricket frog, Syhadra frog, Bombay wart frog, and many others, is a species of frog in the family Dicroglossidae found in India, Bangladesh, and Nepal at low to moderate elevations.[2] It is the type species of genus Minervarya.[2] In view of its wide distribution and stable population trend, IUCN assessors listed it as Least Concern in 2009 and 2016.[1]

Description

The long-legged cricket frog is a small-sized frog. Females reach a snout–vent length (SVL) of 20.7–22.8 mm. Males are smaller with a SVL of 17.5–19.1 mm.[3]

Distribution and habitat

Long-legged cricket frogs are widely distributed over much of central northern India and western Peninsular India, Bangladesh, southern Nepal, from lower Punjab to Sindh in Pakistan, and found at elevations below 2,000 metres (6,600 ft).[1] In Nepal's Shivapuri Nagarjun National Park, 13 specimen were observed in the summer of 2009 within a distance of 50 metres (160 ft) from water bodies.[4]

Behaviour and ecology

During the breeding season, males emit advertisement calls, using a single subgular external vocal sac. They start calling after one or two heavy pre-monsoon or monsoon rains in April to June, and continue up to the end of the rainy season in September to October. They call mainly during the night beginning after dusk and continue until the early morning of the following day, preferably sitting in temporary shallow water pools under partly submerged grass or paddy. They call in chorus but maintain a distance of 0.5 to 1 m to each other. Their calls are antiphonal between the two nearest calling males and consist of a series of pulse groups varying per call between 7 and 28.[3]
