	abstract = {We compared chromosome morphologies for 11 species of Malagasy poison frogs, genus Mantella, and three outgroup taxa (genus Mantidactylus) using conventional and fluorescence staining techniques. All species studied had a karyotype of 2n=26, with five larger and eight smaller chromosome pairs. The 11th pair was acrocentic in Mantella nigricans represents the first such observation in the genus. The nucleolus organizer region (NOR) was located at secondary constrictions on chromosome pair 2 in all Mantella studied and in Mantidactylus grandisonae (while located on other chromosomes in all other species of Mantidactylus studied so far). Heterochromatin distribution was highly variable among Mantella species; C-bands positively staining with DAPI and CMA3 were observed. The possible structure of these bands, seemingly containing both A+T rich and C+G rich heterochromatin, is discussed. Phylogenetic reconstruction using chromosomal characters provided very little information. Evolution of the characters studied is probably either too fast (heterochromatin arrangement) or too slow (NOR location) to match the main cladogenetic events among Mantella species groups.},

	abstract = {In the face of accelerating declines in amphibian populations, it is crucial to be able to effectively identify conservation priorities, both in terms of species and localities. Rapid assessment of amphibian community structure is therefore essential. Visual encounter Survey (VES) and standardized Visual transect sampling (SVTS) are becoming increasingly important in the measurement and monitoring of tropical anuran communities. In the present paper we compare the performance of SVTS along seven tropical forest transects where frog communities are currently being monitored: Lalut Birai (Borneo, Indonesia), Kakamega Forest National Reserve (Kenya, Africa), Tai National Park (Ivory Coast, Africa; two transects) and Ambolokopatrika-Betaolana Rainforest (Madagascar, three transects). We compared species lists generated from the transects with those from the entire study areas. Species richness was estimated using different incidence- and abundance-based richness estimators: ACE, ICE, Chao1, Chao2, Firsa-order jackknife, Michaelis Menton Estimators (MMMeans and MMRuns). Only, a few transect characteristics had a significant effect on species richness estimate accuracy. Species saturation was significantly enhanced by the number of transect walks (n(counts)). The relative standard deviation of the First-order jackknife estimator significantly decreased with an increasing daily species richness and a combined effect of daily species richness and the overall abundance of frogs. Comparison of transect: and forest: species lists show that terrestrial species are best represented by VES/SVTS. We recommend that a transect census Should be performed on at least 20 independent walks. Different species richness estimators should be applied simultaneously since their behavior/effectiveness under a wide array of transect parameters is still unknown.},
