Each species was most abundant at a particular time and location; the most common species were the most distinct in this regard.

	abstract = {A new ranid frog is described from the mountains of the southwestern Cape Province, South Africa. It is placed in the Petropedetinae, but cannot be assigned to any existing genus. We erect the genus POYNTONIA to accommodate it and name the new frog Poyntonia paludicola. Poyntonia may be separated from the other genera of petropedetine ranids by the absence of a tympanum, the lack of digital discs, a tarsal tubercle, and lingual papilla, and the presence of webbing and an ossified omosternum. Populations of Poyntonia paludicola are known from five localities, all marshy habitats at high elevations in the southwestern Cape mountains. Adults are of moderate size (SVL 30 mm) and are very warty. The tadpoles are distinguishable from other ranid tadpoles by their small mouth, long tail, and presence of minute sharp tubercles in areas corresponding to positions of adult warts. The diploid chromosome number is 2N = 24. A sonagram of the male advertisement call is presented.},

The new taxon seems most closely allied to Petropedetes Reichenow 1874, from West Africa, and to Arthroleptides Nieden 1910, which is found in Kenya and Tanzania. It resembles these genera in being associated with fast-flowing forest streams and there is circumstantial evidence of a terrestrial life cycle, perhaps similar to that observed in some species of Petropedetes. Morphological features which are considered to justify the recognition of a new genus include the small size and distinctive habitus of the animal, significantly reduced first finger and subarticular tubercles, and a striking ventral colour pattern.</p>

	abstract = {There is an increasing need for protected areas to conserve biodiversity efficiently. The Anura of sub-equatorial Africa have received little attention, but we quantitatively analyse a database containing presence-only data for anurans of sub-equatorial Africa to determine patterns of distribution and species richness, and discuss the roles of present and past environmental conditions in shaping these patterns. We consider the distribution of areas rich in endemic, range-restricted and Red Data Book (RDB) species to identify areas of significance to conservation. The Eastern Highlands of Zimbabwe and adjacent area in Mozambique, southeastern Malawi and the northern coast of KwaZulu/Natal are particularly species rich, whereas the southwestern Cape of South Africa and northwestern Zambia exhibit high degrees of endemism. Four major biogeographical sub-regions are identified, which can be further subdivided into provinces. All statistically significant, current environmental factors together account for 52.6\% of species richness. Annual maximum rainfall, soil type variation, minimum temperature and range of elevation were all positively correlated with species richness. Thus, both habitat influences and history appear to have influenced patterns of anuran richness in the region. Generally, areas of high species richness coincide with those high in range-restricted, endemic and RDB species. In South Africa, the northeastern coast and southwestern Cape are hypothesised to have been both refugia and centres of speciation. Results suggest that the current reserve system in sub-equatorial Africa is inadequate for the conservation of the full complement of anuran species in the region.},

	abstract = {Miniaturization has evolved numerous times and reached impressive extremes in the Anura. I compared the skeletons of miniature frog species to those of closely related larger species to assess patterns of morphological change, sampling 129 species from 12 families. Two types of morphological data were examined: (1) qualitative data on bone presence and absence; and (2) thin-plate spline morphometric descriptions of skull structure and bone shape. Phylogenetic comparative methods were used to address the shared history of species. Miniature anurans were more likely to lose skull bones and phalangeal elements of the limbs. Their skulls also showed consistent differences compared to those of their larger relatives, including relatively larger braincases and sensory capsules, verticalization of lateral elements, rostral displacement of the jaw joint, and reduction of some skull elements. These features are explained by functional constraints and by paedomorphosis. Variation among lineages in the morphological response to miniaturization was also explored. Certain lineages appear to be unusually resistant to the morphological trends that characterize miniature frogs as a whole. This study represents the first large-scale examination of morphology and miniaturization across a major, diverse group of organisms conducted in a phylogenetic framework and with statistical rigor.},
