O. Box 1024, Atherton, Queensland 4883, Australia Accepted on September 22, 2011. Published online at www.vertebrate-zoology.de on December 13, 2011. > Abstract Five new species of microhylid frogs in the genera Albericus, Cophixalus and Oreophryne are described from high altitudes in the Kaijende Highlands of Enga Province, central Papua New Guinea. A population of short-legged, terrestrial Albericus discovered in grasslands on the Kaijende Highlands seems to be very close to the recently described A. alpestris. Because the systematic status of our new frogs is not yet clear, they are referred to as Albericus cf. alpestris in our paper. Information about the advertisement call of this population, its colour in life, and its habitat is presented for the fi rst time and enables possible inferences about Albericus alpestris sensu stricto. > Kurzfassung Auf der Basis von Aufsammlungen im August/September 2005 werden fünf neue microhylide Froscharten der Gattungen Albericus, Cophixalus und Oreophryne aus der alpinen Zone der Kaijende Highlands, Enga Province, zentrales Papua Neu- guinea, beschrieben. Im gleichen Gebiet wurde eine Population kurzbeiniger und terrestrisch lebender Frösche der Gattung Albericus entdeckt, die der kürzlich nur anhand von wenigen Museumsexemplaren beschriebenen Art Albericus alpestris stark ähneln. Informationen zum Paarungsruf, zur Lebendfärbung und zum Habitat dieser Frösche werden erstmalig gege- ben. Da ihre endgültige systematische Stellung noch zu klären ist, werden sie hier als Albericus cf. alpestris bezeichnet. > Key words Amphibia, Anura, Microhylidae, Albericus, Cophixalus, Oreophryne, new species, Papua New Guinea.

  • Polyploidy and Sex Chromosome Evolution in Amphibians

    Polyploidy and Sex Chromosome Evolution in Amphibians

    Chapter 18 Polyploidization and Sex Chromosome Evolution in Amphibians Ben J. Evans, R. Alexander Pyron and John J. Wiens Abstract Genome duplication, including polyploid speciation and spontaneous polyploidy in diploid species, occurs more frequently in amphibians than mammals. One possible explanation is that some amphibians, unlike almost all mammals, have young sex chromosomes that carry a similar suite of genes (apart from the genetic trigger for sex determination). These species potentially can experience genome duplication without disrupting dosage stoichiometry between interacting proteins encoded by genes on the sex chromosomes and autosomalPROOF chromosomes. To explore this possibility, we performed a permutation aimed at testing whether amphibian species that experienced polyploid speciation or spontaneous polyploidy have younger sex chromosomes than other amphibians. While the most conservative permutation was not significant, the frog genera Xenopus and Leiopelma provide anecdotal support for a negative correlation between the age of sex chromosomes and a species’ propensity to undergo genome duplication. This study also points to more frequent turnover of sex chromosomes than previously proposed, and suggests a lack of statistical support for male versus female heterogamy in the most recent common ancestors of frogs, salamanders, and amphibians in general. Future advances in genomics undoubtedly will further illuminate the relationship between amphibian sex chromosome degeneration and genome duplication. B. J.

Bantimurung Bulusaraung National Park (BabulNP) was gazetted in 2004 to protect the region’s biodiversity and karst ecosystem. However, the park’s herpetofauna is almost unknown. This project consists of three programs: herpetofauna survey in BabulNP, herpetofauna conservation education to local schools, and herpetofauna training for locals and was conducted from July to September 2007. Based on the survey conducted in six sites in the park, we recorded 12 amphibian and 25 reptile species. Five of those species (Bufo celebensis, Rana celebensis, Rhacophorus monticola, Sphenomorphus tropidonotus, and Calamaria muelleri) are endemic to Sulawesi. Two species of the genus Oreophryne are still unidentified. We visited six schools around the park for our herpetofauna conservation education program. The Herpetofauna Observation Training was held over four days with 17 participants from BabulNP staff, local NGOs, school teachers, and Hasanuddin University students. i Conservation of Herpetofauna in Bantimurung Bulusaraung National Park, South Sulawesi, Indonesia Acknowledgements This project would not have been possible without the contribution of many persons.

We characterize a diverse clade of frogs (Kaloula, Microhylidae) in the Philippine island archipelago as an example of an adaptive radiation into three primary habitat specialists or ecotypes. We use a novel phylogenetic estimate for this clade to evaluate the tempo of lineage accumulation and morphological diversification. Because species-level phylogenetic estimates for Philippine Kaloula are lacking, we employ dense population sampling to determine the appropriate evolutionary lineages for diversification analyses. We explicitly take phylogenetic uncertainty into account when calculating diversification and disparification statistics and fitting models of diversification.

Several species are known for their unique paternal care behaviour, which includes guarding of clutches in some and additional froglet transport in other species. We sampled 48 out of 215 New Guinean microhylid species and all but two (Mantophryne and Pherohapsis) of 18 New Guinean genera and analysed a concatenated data set of partial sequences of the mito- chondrial genes 12S and 16S, which comprises 1220 aligned nucleotide positions, in order to infer the phylogenetic relationships within this diverse group of frogs. The trees do provide resolution at shallow, but not at deep branches. Monophyly is rejected for the genera Callulops, Liophryne, Austrochaperina, Copiula, and Cophixalus as currently recognized.

ZooKeys 48: 39–59. doi: 10.3897/zookeys.48.446. Abstract A new genus of diminutive (10.1–11.3 mm) microhylid frogs is described from New Guinea that is unique in its combination of having only seven presacral vertebrae, a reduced phalangeal formula that leaves the fi rst fi ngers and fi rst toes as vestigial nubs, and reduction of the prepollex and prehallux to single elements. Relationships to other genera are unknown, but overall similarity suggests some relationship to Cophixalus, although that genus also diff ers in some muscle characters and likely remains paraphyletic. Th e new genus contains two species, which are among the smallest known frogs in the world. Th eir mini- aturization may be related to their inhabiting leaf litter, exploitation of which may select for small size. Th e new genus is currently known only from one mountaintop in the southeasternmost portion of New Guinea and another on a nearby island.

Pantaron Range in Bukidnon to determine the species richness, conservation status and microhabitat preferences. Field sampling was performed using a combination of belt transect, opportunistic and capture-mark release sampling techniques. Field investigations were done in the agro-ecosystem and montane forest with the elevation ranging from 1,100-1,550 masl. The study documented 18 anuran species belonging to seven families and 15 genera, and approximately 61 % (11 species) are Philippine endemics. Moreover, four (4) noteworthy Mindanao island endemic namely; Ansonia muelleri, Leptobrachium lumadorum, Megophrys stejnegeri, and Pulchrana grandocula. As to the conservation status, Limnonectes magnus was categorized as vulnerable. Majority of the anu-rans were observed near bodies of water such as ponds and streams while other species were collected in the ground microhabitat especially in the leaf litters and fallen and decaying logs. The result of the survey showed high species richness of anurans in Mt. Pantaron Range and more species are likely to be documented if the place is totally explored. Keywords: Mindanao Island, Pantaron Range, Amphibians, Endemism INTRODUCTION Anurans are biological indicator and more sensitive to the environment than other wildlife (Hopkins, 2007).
