	title = {Voice of a giant: bioacoustic data for Mantidactylus guttulatus (Amphibia: Mantellidae)},
	year = {2004},
	abstract = {<p>The endemic radiation of mantellid frogs from Madagascar (Richards et al., 2000; Vences and Glaw, 2001; Vences et al., 2002) includes a large diversity in terms of morphological and ecological adaptations (Blommers-Schloesser and Blanc, 1991). The smallest species have adult snout-vent lengths of only 11-16 mm, while the two largest species reach more than 100 mm: Mantidactylus guttulatus (up to 120 mm) and M. grandidieri (up to 108 mm). In the large genus Mantidactylus (currently about 75 species in 12 subgenera), M. guttulatus is the type species of the subgenus and genus Mantidactylus (Andreone, in press). These giant Malagasy frogs are widespread in the rainforests of the island and are relative easy to observe. They are quite regularly consumed for food (under the local name of \&quot;radakabe\&quot; or \&quot;radaka\&quot;) and can be seen for sale on markets. However, their ecology is so far largely unknown. They are semiaquatic species living in small to medium-sized brooks and torrents but their reproductive behaviour, eggs, tadpoles and vocalizations remained undescribed except for the observation of large oocytes (4- 5 mm) in dissected gravid females. Glaw and Vences (1994) described distress calls of M. grandidieri and hypothesized that, regarding advertisement calls, M. guttulatus may be a non-calling species. In this paper we describe for the first time the advertisement calls of a representative of the subgenus Mantidactylus.</p>

	abstract = {Madagascar hosts a high diversity of small brown frogs. In this paper, we add another one by describing Gephyromantis (Duboimantis) tohatra sp. nov. The new species is a small brown mantellid frog discovered on a recent expedition to Marojejy National Park in northeastern Madagascar. It is characterised, among other things, by its small size (snout-vent length ~33 mm), an orange to yellowish belly, two dorsolateral ridges, and a distinctive call composed of 7{\textendash}10 pulsed notes. The new species occurs sympatrically with other members of the subgenus Duboimantis at high altitude (~1700 m above sea level), including its sister species G. schilfi from which it radically differs by advertisement call and by a substantial genetic divergence of 4.3\% uncorrected pairwise distance in the mitochondrial 16S rRNA gene. It thus joins the diverse assemblage of Gephyromantis species known from high altitudes on the mountain massifs of northern Madagascar.},

	abstract = {<p>We present molecular evidence for the presence of two species morphologically similar to Spinomantis bertini in Andohahela National Park, south-eastern Madagascar, differing by 5.5\&minus;6.3\% pairwise DNA sequence divergences in the mitochondrial 16S rRNA gene. One of these was observed at higher elevations of ca. 1650 m above sea level, whereas the other was found at lower elevations of ca. 715 m a.s.l., close to the type locality of S. bertini (Isaka-Ivondro), and in one other location (Andreoky, ca. 1050 a.s.l.). We herein assign these low- to mid-elevation specimens to S. bertini based on their occurrence near the type locality and general agreement in colour pattern with the type specimen of Gephyromantis bertini Guib\&eacute;, 1947. The high-elevation form is described as Spinomantis beckei sp. nov. based on its molecular divergence and reciprocal monophyly with respect to S. bertini, lower expression of greenish dorsal colour and less distinct frenal stripe. Based on a comparison of published call descriptions for S. bertini and our recordings of S. beckei, we hypothesize that S. bertini has a lower note repetition rate in advertisement calls. Molecular data suggest that the S. bertini species complex is more diverse than previously recognized, with at least two more candidate species identified: S. sp. Ca7 from Ranomafana National Park, and a newly identified candidate species S. sp. Ca12 from Pic d\&rsquo;Ivohibe Special Reserve.</p>
