Stream Frogs, Mannophryne Trinitatis (Dendrobatidae): an Example of Anti-Predator Behaviour
HERPETOLOGICAL JOURNAL, Vol. 11, pp. 91-100 (2001) SELECTION OF TAD POLE DEPOSITION SITES BY MALE TRINIDADIAN STREAM FROGS, MANNOPHRYNE TRINITATIS (DENDROBATIDAE): AN EXAMPLE OF ANTI-PREDATOR BEHAVIOUR J. R. DOWNIE, S. R. LIVINGSTONE AND J. R. CORMACK Division of Environmental and Evolutionary Biology, Institute of Biomedical & Life Sciences, University of Glasgow, Scotland, UK Trinidad's only dendrobatid frog, Mannophryne (=Colostethus) trinitatis, lives by the small streams draining the slopes of the Northern Range mountains and at Tamana Hill in the Central Range. Adults are often very abundant, but tadpoles are found patchily in the streams. In the absence of two potential predators - the fish Rivulus hartii and shrimps of the genus Macrobrachium - tadpoles are abundant in pools. Where the predators are present, tadpoles are uncommon or absent. Tadpoles may also be found in small, isolated bodies of water at some distance from streams. Males carrying tadpoles retained them for 3-4 days, in the absence of suitable pools. When presented with a choice of pools, males preferred to deposit their tadpoles in pools lacking predators. There were differences in behaviour between males fromthe northern and southern slopes of the Northern Range. For example, north coast males deposited tadpoles in pools containing other conspecific tadpoles in preference to empty pools, whereas males from southern slopes made the opposite choice. When presented only with pools containing predators (i.e. shrimps or fish), north coast males shed their tadpoles in damp leaf litter rather than in the pools, while males from the southern slopes deposited tadpoles in pools with shrimps - predators uncommon in the southern slopes streams. -

E-mail: [email protected] Abstract We describe a new species of Cornufer, subgenus Batrachylodes, from high-elevation forests of New Britain Island in the Bismarck Archipelago of Eastern Melanesia. The new species, Cornufer exedrus sp. nov., is a biogeographically disjunct member of the Batrachylodes clade, representing the first record of the subgenus from outside of the Solomon Archipel- ago. The new species is a small terrestrial form from dense, closed-canopy forests above 1500 meters elevation in the Na- kanai Mountains of eastern New Britain. It differs from its closest relatives, the other members of the subgenus Batrachylodes, on the basis of its minute body size, degree of digital disc expansion, reduced subdigital tuberculation, color pattern, and other traits related to its small size. -

With more than 250 species, the Mantellidae is the most species-rich family of frogs in Madagascar. These frogs are highly diversified in morphology, ecology and natural history. Based on a molecular phylogeny of 248 mantellids, we here examine the distribution of three characters reflecting the diversity of eye colouration and two characters of head colouration along the mantellid tree, and their correlation with the general ecology and habitat use of these frogs. We use Bayesian stochastic character mapping, character association tests and concentrated changes tests of correlated evolu- tion of these variables. We confirm previously formulated hypotheses of eye colour pattern being significantly correlated with ecology and habits, with three main character associations: many tree frogs of the genus Boophis have a bright col- oured iris, often with annular elements and a blue-coloured iris periphery (sclera); terrestrial leaf-litter dwellers have an iris horizontally divided into an upper light and lower dark part; and diurnal, terrestrial and aposematic Mantella frogs have a uniformly black iris. -

The Mantellidae is a species-rich family of neobatrachian frogs endemic to Madagascar and Mayotte. Although tadpoles have been described from many mantellids, detailed studies of their early embryonic development are rare. We provide a documentation of the developmental stages of Mantidactylus betsileanus, a common mantellid frog of Madagas- car’s eastern rainforests, based on clutches deposited and raised in captivity. Metamorphosis was completed after 89 days on average. External gills were not recognizable in the embryos, similar to three other, previously studied mantellids, which apparently constitutes a difference to the mantellid sister group, the Rhacophoridae. We also provide updated de- scriptions of the species’ larval morphology at stage 25 and stage 36, respectively, from captive bred and wild-caught indi- viduals, and report variations in the keratodont row formula from 0/2, 1/1, 1/3 to 1:1+1/3.
