“…BPP molecular species delimitation approaches have been developed and widely used in mammals [24, 25], amphibians [26, 27], and reptiles [28, 29]. It should be noted that the biological species concept associated with BPP may not be true in practice [30], and that simulations showed that BPP is robust in the case of incomplete lineage sorting but sensitive to hybridization.…”

Background Niviventer is a genus of white-bellied rats that are among the most common rodents in the Indo-Sundaic region. The taxonomy of the genus has undergone extensive revisions and remains controversial. The current phylogeny is unresolved and was developed primarily on the basis of mitochondrial genes. Identification is extremely difficult, and a large number of GenBank sequences seem to be problematic. We extensively sampled specimens of Niviventer in China and neighboring northern Vietnam, including topotypes of the most reported species (n = 6), subspecies (n = 8), and synonyms (n = 4). We estimated phylogenetic relationships on the basis of one mitochondrial and three nuclear genes, using concatenation and coalescent-based approaches. We also employed molecular species delimitation approaches to test the existence of cryptic and putative new species.ResultsOur phylogeny was finely resolved, especially for the N. confucianus-like species. Our data provided the first support for N. brahma and N. eha as sister species, an assignment that is congruent with their morphological similarities. Species delimitation analyses provided new insight into species diversity and systematics. Three geographic populations of N. confucianus and one of N. fulvescens were supported as genetically distinct in our species delimitation analyses, while three recognized species (N. coninga, N. huang, and N. lotipes) were not strongly supported as distinct.ConclusionsOur results suggested that several genetically distinct species may be contained within the species currently known as N. confucianus and N. fulvescens. In addition, the results of Bayesian Phylogenetics and Phylogeography (BPP) for N. coninga, N. huang, and N. lotipes indicated that either inter-specific gene flow had occurred or imperfect taxonomy was present. Morphological examinations and morphometric analyses are warranted to examine the molecular results.Electronic supplementary materialThe online version of this article (doi:10.1186/s12862-016-0832-8) contains supplementary material, which is available to authorized users.

“…Some caution is warranted for using specimens of P. kuhli from the pet trade to infer ecologically-relevant metrics of glide performance. A recent study has found that these specimens are genetically and morphologically distinct from their con-specifics in the wild, which exhibit less exaggerated cutaneous flaps and webbing (Brown et al 2012b). …”

“…All Draco glide, with flight an integral aspect of their ecology.The family Gekkonidae contains the second largest diversity of gliding lizards, with representatives from Ptychozoon, Hemidactylus (formerly Cosymbotus), and Luperosaurus, all of which are found primarily in Southeast Asia(Brown et al 2012a, Brown et al 2012b, Heinicke et al 2012. The seven species of Ptychozoon are the most specialized gliding…”

How animals glide: from trajectory to morphology

et al. 2015

Animals that glide produce aerodynamic forces that enable transit through the air in both arboreal and aquatic environments. The relative ease of gliding compared with flapping flight has led to a large diversity of taxa that have evolved some degree of flight capability. Glide paths are curved, reflecting the changing forces on the animal as it progresses through its aerial trajectory. These changing forces can be under control of the glider, which uses specific aspects of anatomy to modulate lift, drag, and rotational moments on the body. However, gliders share no single anatomical or behavioral feature, and some species are unspecialized for gliding, producing aerodynamic forces using posture and orientation alone. Animals use gliding in a broad range of ecological roles, suggesting that multiple performance metrics are relevant for consideration, but we are only beginning to understand how gliders produce and control their flight from takeoff to landing. In this review, we focus on the physical aspects of how glide trajectories are produced, and additionally discuss the range of morphologies and postures that are used to control aerial movements across the broad diversity of animal gliders.

“…More recent approaches have embraced the need for consideration of not only diagnostic morphological characters, but inferences of evolutionary history as well (Marshall et al 2006a;Leach e & Mulcahy 2007). In fact, the inclusion of genetic data to delimit boundaries between evolutionary lineages has become paramount in biodiversity studies aimed at accurate estimations of species diversity (Wiens & Penkrot 2002;Knowles & Carstens 2007;Rissler & Apodaca 2007;Welton et al 2010a,b;Barrett & Freudenstein 2011;Setiadi et al 2011;Brown et al 2012).…”

Multilocus phylogeny and Bayesian estimates of species boundaries reveal hidden evolutionary relationships and cryptic diversity in Southeast Asian monitor lizards

et al. 2013

Recent conceptual, technological and methodological advances in phylogenetics have enabled increasingly robust statistical species delimitation in studies of biodiversity. As the variety of evidence purporting species diversity has increased, so too have the kinds of tools and inferential power of methods for delimiting species. Here, we showcase an organismal system for a data-rich, comparative molecular approach to evaluating strategies of species delimitation among monitor lizards of the genus Varanus. The water monitors (Varanus salvator Complex), a widespread group distributed throughout Southeast Asia and southern India, have been the subject of numerous taxonomic treatments, which have drawn recent attention due to the possibility of undocumented species diversity. To date, studies of this group have relied on purportedly diagnostic morphological characters, with no attention given to the genetic underpinnings of species diversity. Using a 5-gene data set, we estimated phylogeny and used multilocus genetic networks, analysis of population structure and a Bayesian coalescent approach to infer species boundaries. Our results contradict previous systematic hypotheses, reveal surprising relationships between island and mainland lineages and uncover novel, cryptic evolutionary lineages (i.e. new putative species). Our study contributes to a growing body of literature suggesting that, used in concert with other sources of data (e.g. morphology, ecology, biogeography), multilocus genetic data can be highly informative to systematists and biodiversity specialists when attempting to estimate species diversity and identify conservation priorities. We recommend holding in abeyance taxonomic decisions until multiple, converging lines of evidence are available to best inform taxonomists, evolutionary biologists and conservationists.
