These sperm features are also important in phylogenetic inferences. It appears that the axoneme-undulating membrane-axial rod represents a plesiomorphic character. This pattern has been simplified to a single axoneme as a secondary reversal for external fertilization in many anurans or has developed as a double axoneme as in Chiromantis xerampelina. Sperm head and acrosome length are predictive in distinguishing between terrestrial and aquatic anuran fertilizers. Sperm motility is species specific among representatives of seven of the nine South African families and motile sperm which exhibit forward progression are the rule for aquatic fertilizing anurans. In contrast, the sperm of terrestrial fertilizing anurans are immotile in a wide range of physiological/culture media with osmotic concentrations varying from 10 to 300 mOsm/kg. The term ect-terrasperm is suggested as a new terminology for amphibians which exhibit the terrestrial mode of fertilization.}, url = {://PREV199698744907}, author = {Van Der Horst, Gerhard and Wilson, Brian and Channing, Alan} } @article {204, title = {Genetic variation between two subspecies of reedfrogs in the genus Hyperolius (Anura: Hyperoliidae)}, journal = {Madoqua}, volume = {19}, number = {1}, year = {1995}, month = {1995}, pages = {33-36}, abstract = {Two subspecies of reedfrogs Hyperolius marmoratus broadleyi (eastern Zimbabwe) and Hyperolius marmoratus verrucosus (Tsitsikama area - Knysna) were analyzed for variation in nuclear ribosomal DNA by mapping restriction endonuclease sites.

The taxonomy of the Hyperolius viridiflavus complex, a group of African frogs, has been problematic. Mitochondrial DNA sequence data were used to reconstruct the phylogenetic history of these frogs. The phylogeny showed that subspecies were grouped into clades, within which certain taxa were not supported by fixed characters. We used the phylogenetic species concept to identify the smallest monophyletic clades supported by at least one fixed character, and suggest taxonomic revisions based on our results. We identify ten species within the H. viridiflavus complex.

Methods We compiled distributional maps of all species, summarized historical changes in vegetation and climate in Africa since the late Cretaceous, and used these in combination to identify historical factors that may have contributed to speciation in these frogs. A phylogeny for Hyperolius was derived from mtDNA sequence data and interpreted in terms of climatic and vegetation changes in Africa. Main conclusions Lowland rainforest is proposed to have been the ancestral habitat of Hyperolius. The expansion of savannah and reduction of lowland rainforest were identified as important factors in the differentiation of the more basal species.

In lateral view, the tips arc noticeably flattened.}, url = {://PREV200700148839}, author = {Msuya, Charles A. and Howell, Kim M. and Channing, Alan} } @article {120, title = {The mud dwelling tadpole of the Long-toed Tree Frog, Leptopelis xenodactylus (Arthroleptidae)}, journal = {Herpetological Review}, volume = {39}, number = {3}, year = {2008}, month = {Sep 2008}, pages = {288-290}, url = {://PREV200800639291}, author = {Channing, Alan} } @article {375, title = {A new species of Arthroleptella Hewitt, 1926 (Anura: Pyxicephalidae) from the Klein Swartberg Mountain, Caledon, South Africa}, journal = {African Journal of Herpetology}, volume = {57}, number = {1}, year = {2008}, month = {Jun 2008}, pages = {1-12}, abstract = {A new species of moss frog (genus Arthroleptella) is described from the Klein Swartberg Mountain near Caledon in the Western Cape Province, South Africa to which it is confined.
