| Assemblages that are exposed to recurring temporal environmental changes can show changes in their ecological properties. These can be expressed by differences in diversity and assembly rules. Both can be identified using two measures of diversity: functional (FD) and phylogenetic diversity (PD). Frog communities are understudied in this regard, especially during the tadpole life stage. We utilised tadpole assemblages from Madagascan rainforest streams to test predictions of seasonal changes on diversity and assemblage composition and on diversity measures. From the warm-wet to the cool-dry season, species richness (SR) of tadpole assemblages decreased. Also FD and PD decreased, but FD less and PD more than expected by chance. During the dry season,... |

| As a general trend, accounts on regional and local herpetofaunas tend to become more and more colourful and extensive, and the classical borders between fieldguide, distribution atlas and handbook are fading. The book reviewed here is a good example for this trend. Edited by Rémi Duguet und Frédéric Melki for the “Association pour la Connaissance et l’Etude du Monde Animal et Végetal” (ACEMAV), it summarizes the state of knowledge on the amphibians of France, Luxembourg and Belgium. Thereby it bridges a very important gap, because no comprehensive account on this region was so far available – despite its “batrachophilic” character, expressed in the yearly import of over 2970 tons of frog limbs to France, 2100 t to Belgium and 34 t to Luxembourg for... |

| A revision of species included in the subgenus Laurentomantis (genus Mantidactylus) yielded new information about phylogeny, taxonomy, and biogeography of the endemic mantellid frog radiation in Madagascar. Four Laurentomantis species, distinguished by morphology and advertisement calls, are recognized: Mantidactylus (Laurentomantis) horridus (Northern and North- Western biogeographic regions), M. (L.) ventrimaculatus (South- East and East); M. (L.) malagasius (East); and the new species M. (L.) striatus (North-East). M. striatus and M. malagasius are probably sister species based on bioacoustic and morphological affinities. A tibial gland, so far unknown in anurans, is described in M. malagasius and M. horridus. A phylogenetic analysis of 54 mainly... |

| Considered as one of the worldwide hotspots for biodiversity conservation (Myers et al., 2001), Vietnam has been the aim of recent expeditions of several major European research institutes, such as the Muséum national d’Histoire naturelle in Paris (Ohler et al., 2000), the Russian Academy of Sciences in St. Petersburg (e.g., Orlov et al., 2000), or the National Museum Leiden (Anonymous, 2002). The high zoological interest of Vietnam is exemplified by the recent discoveries of several new large mammal species. Although one of these, the bovid Pseudonovibos spiralis, is most probably non-existing but based on fake horns (Feiler et al., 2002; Olson and Hassanin, 2003), the fact that three new ungulate species could be added to Vietnam’s megafauna in less than... |
