Patterns of diversification in species-rich clades provide insight into the processes that generate biological diversity. We tested different models lineage and phenotypic an exceptional continental radiation, ovenbird family Furnariidae, using most complete species-level phylogenetic hypothesis produced to date for a major avian clade (97% 293 species). found Furnariidae exhibit nearly constant rates accumulation but show evidence constrained morphological evolution. This pattern sustained...
Avian diversification has been influenced by global climate change, plate tectonic movements, and mass extinction events. However, the impact of these factors on hyperdiverse perching birds (passerines) is unclear because family level relationships are unresolved timing splitting events among lineages uncertain. We analyzed DNA data from 4,060 nuclear loci 137 passerine families using concatenation coalescent approaches to infer a comprehensive phylogenetic hypothesis that clarifies all...
The Black Rat (Rattus rattus) spread out of Asia to become one the world's worst agricultural and urban pests, a reservoir or vector numerous zoonotic diseases, including devastating plague. Despite global scale inestimable cost their impacts on both human livelihoods natural ecosystems, little is known genetic diversity Rats, timing directions historical dispersals, risks associated with contemporary movements. We surveyed mitochondrial DNA Rats collected across range as first step towards...
Diversity does not drive speciation The role of the environment in origin new species has long been debated. Harvey et al. examined evolutionary history and diversity suboscine birds tropics (see Perspective by Morlon). Contrary to expectations that have higher rates speciation, authors observed more constant occur harsh environments relative tropics. Thus, for this group birds, diversification temperate Arctic regions followed movement retention results their local levels diversity. Science...

It has long been appreciated that analyses of genomic data (e.g., whole genome sequencing or sequence capture) have the potential to reveal tree life, but it remains challenging move from a clear understanding evolutionary history, in part due computational challenges phylogenetic estimation using genome-scale data. Supertree methods solve challenge because they facilitate divide-and-conquer approach for large-scale phylogeny inference by integrating smaller subtrees computationally...

Summary Austral migrants are species that breed in temperate areas of South America and migrate north, towards or into Amazonia, for the southern winter. Migrations among these most extensive Southern Hemisphere migrations, austral system represents a third major migration system, sense term has been applied to Northern temperate-tropical migration. The geography greatly influences system. Lack east-west geographical barriers shape continent promote pattern partially overlapping breeding...
Relationships within the rhinocryptid genus Pteroptochos (huet-huets and turca) were investigated using complete sequences of mitochondrial genes COII ND3. Phylogenetic analysis multiple individuals per taxon revealed that P. castaneus, tarnii, megapodius constitute separate lineages, with castaneus tarnii as sister taxa, to these. Bootstrap support for these results was strong (79-100%). Sequence divergence between species high, ranging from 6.1% 7.6% megapodius. High genetic is consistent...
The infraorder Furnariides is a diverse group of suboscine passerine birds comprising substantial component the Neotropical avifauna. included species encompass broad array morphologies and behaviours, making them appealing for evolutionary studies, but size (ca. 600 species) has limited well-sampled higher-level phylogenetic studies. Using DNA sequence data from nuclear RAG-1 RAG-2 exons, we undertook analysis sampling 124 (more than 88%) genera. Basal relationships among family-level taxa...

The Australian Brush-tailed Phascogale (Phascogale tapoatafa sensu lato) has a broad but highly fragmented distribution around the periphery of continent and all populations are under significant ongoing threat to survival. A new appraisal morphological molecular diversity within group reveals that population in 'Top End' Northern Territory is specifically distinct from others, including those Kimberley region Western Australia west on Cape York Queensland east. name P. pirata Thomas, 1904...

Historical ecology is becoming an important focus in conservation biology and offers a promising tool to help guide ecosystem management. Here, we integrate data from multiple disciplines illuminate the past, present, future of biodiversity on California's Channel Islands, archipelago that has undergone wide range land-use ecological changes. Our analysis spans approximately 20,000 years, before human occupation through Native American hunter–gatherers, commercial ranchers fishers, US...

Because a broad spectrum of resource use allows species to persist in wide range habitat types, and thus permits them occupy large geographical areas, because broadly distributed have access more diverse bases, the breadth hypothesis posits that diversity resources used by organisms should be positively related with extent their geographic ranges. We investigated isotopic niche width small radiation South American birds genus Cinclodes. analysed feathers 12 Cinclodes test version examine...
