“…Genetic divergence between these two taxa indicates that gene flow last occurred in the late Miocene. Genetic and morphological data indicate that a number of other montane components of the North Papuan Ranges fauna are also most closely related to (and sometimes also nested within) lineages in the Central Cordillera (Flannery 1993; Richards et al. 2009; Meredith et al.…”

Oliver, P.M., Richards, S.J. & Sistrom, M. (2012). Phylogeny and systematics of Melanesia's most diverse gecko lineage (Cyrtodactylus, Gekkonidae, Squamata). -Zoologica Scripta, 41, 437-454. The systematics and biogeographical history of the diverse fauna of New Guinea and surrounding islands (Melanesia) remain poorly known. We present a phylogeny for 16 of the 21 recognised Melanesian bent-toed geckos in the genus Cyrtodactylus based on mitochondrial sequence data. These analyses reveal two divergent lineages of Cyrtodactylus within Melanesia. One includes a single recognised species with clear affinities to sampled taxa from Asia. The other comprises a relatively diverse radiation (likely 30+ species), not closely related to sampled extralimital taxa and centred on the Melanesian region (including Australia). Many taxa within this second lineage are endemic to islands surrounding New Guinea, and dispersal and speciation on peripheral islands appears to have played an important role in the accumulation of species diversity within this clade. In contrast, little diversity is centred upon montane areas, although we do identify at least one lineage closely associated with hill and lower montane forest that probably dates to at least the late Miocene. Our phylogenetic analyses also reveal numerous divergent lineages that require taxonomic attention, including at least two widespread taxa that are likely to be composite, additional specimens of Cyrtodactylus capreoloides (until recently known only from the holotype) and several divergent and completely novel lineages, two of which we introduce herein: Cyrtodactylus arcanus sp. n. and Cyrtodactylus medioclivus sp. n.

“…The Pelodryadinae hylid lineage is the second largest radiation of the five frog families represented in Australia. It currently is comprised of two genera and 86 described species in Australia (although some still recognize only a single genus Litoria pending future taxonomic revision; Frost, 2014) and 176 species in the Australo-Papuan region, but there are certainly many more undescribed species, particularly in Papua (Kraus & Allison, 2004;Richards & Oliver, 2006;Oliver et al, 2008;Richards et al, 2009). Australian hylids occupy an extensive array of ecotypes ranging from species that are primarily fossorial, to those that are highly aquatic, and also species that occupy a wide range of terrestrial microhabitats including rocky areas, grasslands, rainforest canopy and wet sclerophyll forest litter (Cogger, 2014).…”

Animals from different clades but subject to similar environments often evolve similar body shapes and physiological adaptations due to convergent evolution, but this has been rarely tested at the transcontinental level and across entire classes of animal. Australia's biome diversity, isolation and aridification history provide excellent opportunities for comparative analyses on broad-scale macroevolutionary patterns. We collected morphological and environmental data on eighty-four (98%) Australian hylid frog species and categorized them into ecotypes. Using a phylogenetic framework, we tested the hypothesis that frogs from the same ecotype display similar body shape patterns: (i) across all the Australian hylids, and (ii) through comparison with a similar previous study on 127 (97%) Australian myobatrachid species. Body size and shape variation did not follow a strong phylogenetic pattern and was not tightly correlated with environment, but there was a stronger association between morphotype and ecotype. Both arboreal and aquatic frogs had long limbs, whereas limbs of fossorial species were shorter. Other terrestrial species were convergent on the more typical frog body shape. We quantified the strength of morphological convergence at two levels: (i) between fossorial myobatrachid and hylid frogs, and (ii) in each ecomorph within the hylids. We found strong convergence within ecotypes, especially in fossorial species. Ecotypes were also reflected in physiological adaptations: both arboreal and cocooned fossorial frogs tend to have higher rates of evaporative water loss. Our results illustrate how adaptation to different ecological niches plays a crucial role in morphological evolution, boosting phenotypic diversity within a clade. Despite phylogenetic conservatism, morphological adaptation to repeatedly emerging new environments can erase the signature of ancestral morphotypes, resulting in phenotypic diversification and convergence both within and between diverse clades.

“…The high Central Cordillera is the dominant mountain complex in New Guinea, however the lower and smaller upland regions of the North Papuan Mountains also have an endemic biota that remains poorly understood (Helgen 2007; Richards et al 2009; Kraus and Myers 2012). The North Papuan Mountains are derived from the (ongoing) accretion of formerly isolated island arcs onto the northern edge of New Guinea (Polhemus 2007).…”

The diverse biota of New Guinea includes many nominally widespread species that actually comprise multiple deeply divergent lineages with more localised histories of evolution. Here we investigate the systematics of the very large geckos of the Cyrtodactylus novaeguineae complex using molecular and morphological data. These data reveal two widespread and divergent lineages that can be distinguished from each other, and from type material of Cyrtodactylus novaeguineae, by aspects of size, build, coloration and male scalation. On the basis of these differences we describe two new species. Both have wide distributions that overlap extensively in the foothill forests of the North Papuan Mountains, however one is seemingly restricted to hill and lower montane forests on the ranges themselves, while the other is more widespread throughout the surrounding lowlands. The taxon endemic to the North Papuan Mountains is related to an apparently lowland form currently known only from Waigeo and Batanta Island far to the west – hinting at a history on island arcs that accreted to form the North Papuan Mountains.
