A small number of treefrog species (Litoria) from Melanesia are unusual amongst Anura in having distinctive fleshy rostral spikes. Here, we first present an extended description for Litoria pronimia Menzies, a that is widespread along the southern edge Central Cordillera New Guinea, and which males have long erectile spike. Second, describe pinocchio sp. nov. new, morphologically similar, yet geographically disjunct Foja Mountains northern Papua Province, Indonesia. The new differs aspects...
We describe a new species of large green treefrog from southern Papua Province, Indonesia. Litoria lubisi sp. nov. is placed in the L. infrafrenata Group based on its size, colouration and configuration hand webbing, but differs other members this group aspects body size proportions, extent male advertisement call. occurs close proximity to two Group, emphasising an until-recently overlooked pattern that multiple large, arboreal have overlapping distributions across much lowlands New Guinea.
W hile engaged in the examination of some vase pictures which have been stated to represent certain parts shores Bay Pozzuoli as it existed Roman times, I was struck by two drawings Oyster culture grounds, or ostrearia, seem me be considerable interest, not only affording us direct information concerning method oyster employed Romans neighbourhood Baiæ, but also because they show clearly that same one still survives and is carried on, common with so many other customs locality, exactly...
THE fired rocks and hills of volcanic origin stand in so striking a contrast to those aqueous origin, that they have exercised very powerful influence on the thoughts man all ages. Frequently associated with such formations are phenomena which we accustomed refer as volcanic—“burning mountains,” boiling springs, gaseous exhalations, terrifying noises—all shrouded mystery demands explanation. Even locality fires been extinguished or long remained quiescent, peculiar configuration ground often...
Abstract Identifying hotspots of biological diversity is a key step in conservation prioritisation. Melanesia—centred on the vast island New Guinea—is increasingly recognised for its exceptionally species-rich and endemic biota. Here we show that Melanesia has world’s most diverse insular amphibian fauna, with over 7% global frog species less than 0.7% land area, 97% endemic. We further estimate nearly 200 additional candidate have been discovered but remain unnamed, pointing to total fauna...
Cytological aspects of hemiclonal (meroclonal) inheritance in diploid and triploid males the hybridogenetic frog Rana esculenta (Rana ridibunda × lessonae) have been studied by DNA flow cytometry. The fact that R. genome contains 16% more than lessonae provides ability to discern cells containing genomes any species from water-frog complex under study. Data are presented showing elimination occurs certain populations. In males, cytogenetic mechanism is simpler diploids: after a (always...
of the African Lakes Company, informed Dr. A. Gfinther that he lied observed Medusm in large numbers one bays Lake Tanganyika.~ They were about ~ an inch diameter, and their rounded top was so clear as to give tile idea they merely circular bodies not shape ordinary Medusa ; more opaque ovaries gave this appearance."At same time Mr. Moir kindly undertook obtain specimens properly prepared with osmic acid; and, thanks assistance J. Swaun, these arrived good condition at end last year.This...
We describe two new species of asterophryine microhylid frogs from the Gulf Province lowlands south-central Papua New Guinea. Cophixalus flavopunctatus sp. nov. is a small member genus (SUL 13.5–15.5 mm) that most commonly encountered on stream banks. It can be distinguished all congeners by its size and presence yellow tubercles dorsum. Calling activity appears to peak in early morning evening when males produce train melodious peeping notes within litter forest floor. Oreophryne purari...
‘Soleo eniin et in aliena castra transire, non tamquam transfuga, sed explorator.’ Seneca, Epistul. Mor. I., Ep. II. Some years ago it occurred to the author that certain submerged ruins Bay of Naples were sufficiently well preserved repay investigation with a view supplementing history post-Roman land-movements, as recorded upon columns Macellum Puteoli, commonly known “Temple Serapis.”
Higher-level systematics in amphibians is relatively stable. However, recent phylogenetic studies of African torrent-frogs have uncovered high divergence these phenotypically and ecologically similar frogs, particular between West versus Central (Petropedetes) East (Arthroleptides Ericabatrachus) lineages. Because the considerable molecular divergence, external morphology single torrent-frog species a new genus was erected (Odontobatrachus). In this study we aim to clarify systematic...
Cytological evidence for two germ cell lineages, each with the DNA-content of one parental species only, was obtained certain males hybridogenic water frog Rana esculenta (R. ridibunda x R. lessonae) by means DNA flow cytometry. The approach based on 16 +/- 2% difference in genomes species. Two types cells were observed six out 39 studied from populations where such did exist. term 'hybrid amphispermy' is proposed phenomenon. Occurrence suggests that direction elimination (i.e., which genome...
Abstract A complete catalogue is provided of the type specimens geckos in herpetological collection Zoological Museum, Museum Natural History, Berlin as December, 1989. Besides a few cases which status types questionable, contains 282 93 taxa. 63 these taxa are presently regarded valid at specific or subspecific level.
The mosaic was fixed in a small niche wall of the buildings Imperial Villa on Posilipo, near Naples. One part site, now submerged beneath sea consequence post-Roman land movement, has already been described, but later surveys very extensive antiquities and ruins hill above still await publication. Among other discoveries, we have able to find evidence that this fine property, stated left by Vedius Pollio Augustus, imperial possession as late reign Hadrian, considerable alterations were made...
