Next-Generation Biogeography In 1876, Alfred Russel Wallace mapped the zoogeographical regions of world, based on distributions and taxonomic relationships broadly defined mammalian families. Wallace's classification became a cornerstone modern biogeography reference for wide variety biological disciplines, including global biodiversity conservation sciences. Holt et al. (p. 74 , published online 20 December) present next-generation map wallacean zoogeographic regions, incorporating...
Development of phylogenetic methods that do not rely on fossils for the study evolutionary processes through time have revolutionized field biology and resulted in an unprecedented expansion our knowledge about tree life. These helped to shed light macroevolution many taxonomic groups such as placentals (Mammalia). However, despite increase studies addressing diversification patterns organisms, no synthesis has addressed case most diversified mammalian clade: Rodentia. Here we present a...
A central paradigm in island biogeography has been the unidirectional “downstream” colonization of islands from continents (source to sink) based on idea that less-diverse communities are easier invade than biologically more-diverse continental communities. Recently, several cases “upstream” (from continents) have documented, challenging traditional view. However, all these involved individual species colonized mainland regions. Here, using molecular phylogenetic data, divergence time...
Adaptive radiation is the rapid diversification of a single lineage into many species that inhabit variety environments or use resources and differ in traits required to exploit these. Why some lineages undergo adaptive not well-understood, but filling unoccupied ecological space appears be common feature. We construct complete, dated, species-level phylogeny endemic Vangidae Madagascar. This passerine bird represents classic, poorly known, avian radiation. Our results reveal an initial...
With almost 2,600 species, Rodentia is the most diverse order of mammals. Here, we provide an overview changes in our understanding systematics living rodents, including species recognition and delimitation, phylogenetics, classification, with emphasis on last three decades. Roughly, this corresponds to DNA sequencing era rodent systematics, but field undergoing a transition into genomic era. At least 248 were newly described period 2000–2017, novelties such as first member Diatomyidae murid...
The Capromyidae (hutias) are endemic rodents of the Caribbean and represent a model dispersal for non-flying mammals in Greater Antilles. This family has experienced severe extinctions during Holocene its phylogenetic affinities with respect to other caviomorph relatives still debated as morphological molecular data disagree. We used target enrichment next-generation sequencing mitochondrial nuclear genes infer relationships hutias, estimate their divergence ages, understand mode found that...
Recent fossil discoveries have demonstrated that Africa and Asia were epicentres for the origin and/or early diversification of major living primate lineages, including both anthropoids (monkeys, apes humans) crown strepsirhine primates (lemurs, lorises galagos). Competing hypotheses favouring either an African or Asian rank among most hotly contested issues in paleoprimatology. The Afrocentric model anthropoid origins rests heavily on >45 Myr old Algeripithecus minutus from Algeria,...
Abstract Anomaluromorpha is a particularly puzzling suborder of Rodentia. Endemic to Africa, this clade includes the extant genera Idiurus , Anomalurus Zenkerella and Pedetes . These rodents present an hystricomorphous condition skull, characterized by large infraorbital foramen, which evolved independently within mouse‐related over span approximately 57 million years. They exhibit high disparity in craniomandibular dental morphology that has kept their phylogenetic affinities disputed for...

We investigated the relationships 14 Echimyidae (spiny rats), one Myocastoridae (nutrias) and Capromyidae (hutias) genera based on three newly sequenced nuclear genes ( APOB GHR RBP3 ) five previously published markers (the RAG1 vWF mitochondrial cytochrome b 12S rRNA 16S rRNA). recovered...
Crows and ravens (Passeriformes: Corvus) are large-brained birds with enhanced cognitive abilities relative to other birds. They among the few non-hominid organisms on Earth be considered intelligent well-known examples exist of several crow species having evolved innovative strategies even use tools in their search for food. The 40 Corvus have also been successful dispersers distributed most continents remote archipelagos.
The Indo-Pacific region has arguably been the most important area for formulation of theories about biogeography and speciation, but modern studies tempo, mode magnitude diversification across this are scarce. We study biogeographic history characterize levels in wide-ranging passerine bird Erythropitta erythrogaster using molecular, phylogeographic population genetics methods, as well morphometric plumage analyses. Our results suggest that E. colonized during Pleistocene an eastward...
Abstract Aim To determine the historical dynamics of colonization and whether relative timing predicts diversification rate in species‐rich, murine rodent communities Indo‐Australia. Location Indo‐Australian Archipelago including Sunda shelf continental Asia, Sahul Australia, Philippines Wallacea Indonesia. Taxon Order Rodentia, Family Muridae. Methods We used a fossil‐calibrated molecular phylogeny Bayesian biogeographical modelling to infer frequency temporal sequence transitions among...
Murines are well known for their generalist diet, but several of them display specializations towards a carnivorous diet such as the amphibious Indo-Pacific water-rats. Despite fact that carnivory evolved repeatedly in this group, few studies have investigated associated changes jaw muscle anatomy and biomechanics. Here, we describe muscles cranial water-rat, Hydromys chrysogaster. The architecture musculature six specimens captured both on Obi Papua were studied described using dissections....
Olfaction and thermoregulation are key functions for mammals. The former is critical to feeding, mating, predator avoidance behaviors, while the latter essential homeothermy. Aquatic amphibious mammals face olfactory thermoregulatory challenges not generally encountered by terrestrial species. In mammals, nasal cavity houses a bony system supporting soft tissues sensory organs implicated in either or functions. It hypothesized that cope with aquatic environments, have expanded their capacity...
Linking genes to phenotypes has been a major question in evolutionary biology for the last decades. In genomic era, few studies attempted link olfactory-related different anatomical proxies. However, they found very inconsistent results. This study is first investigate potential relation between olfactory turbinals and receptor (OR) genes. We demonstrated that despite use of similar methodology acquisition data, OR do not correlate with relative absolute surface area turbinals. These results...
The origins and evolution of the outstanding Neotropical biodiversity are a matter intense debate. A comprehensive understanding is hindered by lack deep-time comparative data across wide phylogenetic ecological contexts. Here, we quantify prevailing diversification trajectories drivers in sample 150 phylogenies (12,512 species) seed plants tetrapods, assess their variation regions taxa. Analyses indicate that diversity has mostly expanded through time (70% clades), while scenarios saturated...
This paper focuses on veto supertree methods; i.e., methods that aim at producing a conservative synthesis of the relationships agreed upon by all source trees. We propose desirable properties should satisfy in this framework, namely non-contradiction property (PC) and induction (PI). The former requires does not contain contradict one or combination topologies, whereas latter topological information contained is present tree collectively induced several provide simple examples to illustrate...
