Metamagnusia and Pseudocallulops, two new genera of microhylid frogs from New Guinea (Amphibia, Anura, Microhylidae)
Based on morphological, anatomical, ecological, ethological, and molecular traits, two new genera of microhylid frogs from mainland New Guinea are described. Metamagnusia gen. n. includes two
Genome elimination in diploid and triploid Rana esculenta males: cytological evidence from DNA flow cytometry.
Data are presented showing that elimination of the R. ridibunda genome occurs in hybridogenetic males from certain populations, and the process of elimination can be visualized in triploid males by using DNA flow cytometry to identify cells in the special phase of the spermatogonial cell cycle that is termed the E phase.
Morphological and Bioacoustic Characteristics of Frogs of the Genus Platymantis (Amphibia, Ranidae) in Irian Jaya, with Descriptions of Two New Species
It is supposed that P. punctata is the most primitive of the Platymantis species from New Guinea and adjacent islands and species pairs with derived characters are P. batantae and P. bimaculata.
Two germ cell lineages with genomes of different species in one and the same animal.
Cytological evidence for two germ cell lineages, each with the DNA-content of one of the parental species only, was obtained for certain males of the hybridogenic water frog Rana esculenta by means of DNA flow cytometry, and the term 'hybrid amphispermy' is proposed for the phenomenon.
An Annotated Type Catalogue of the Hemisotid, Microhylid, Myobatrachid, Pelobatid and Pipid Frogs in the Zoological Museum, Berlin
The collection is particularly rich in types of Asian microhylids and contains a total of 120 type specimens representing 53 taxa in the five anuran families under consideration, Thirty-one of these taxa are currently regarded as valid at the specific level.
Derived reproductive modes in New Guinean anuran amphibians and description of a new species with paternal care in the genus Callulops (Microhylidae)
The diversity, distribution, ecology and reproductive biology of the New Guinean anuran amphibians are still poorly known, but recent fieldwork in the western part of New Guinea has documented many new species and revealed derived reproductive modes in some taxa.
