To better determine the history of modern birds, we performed a genome-scale phylogenetic analysis 48 species representing all orders Neoaves using phylogenomic methods created to handle data. We recovered highly resolved tree that confirms previously controversial sister or close relationships. identified first divergence in Neoaves, two groups named Passerea and Columbea, independent lineages diverse convergently evolved land water bird species. Among Passerea, infer common ancestor core...
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...
Birds are the most species-rich class of tetrapod vertebrates and have wide relevance across many research fields. We explored bird macroevolution using full genomes from 48 avian species representing all major extant clades. The genome is principally characterized by its constrained size, which predominantly arose because lineage-specific erosion repetitive elements, large segmental deletions, gene loss. Avian furthermore show a remarkably high degree evolutionary stasis at levels...
Abstract: The monitoring of trends in the status species or habitats is routine developed countries, where it funded by state large nongovernmental organizations and often involves numbers skilled amateur volunteers. Far less natural resources takes place developing agencies have small budgets, there are fewer professionals amateurs, socioeconomic conditions prevent development a culture volunteerism. resulting lack knowledge about presents serious challenge for detecting, understanding,...
Avian faunas vary greatly among montane areas; those at high latitudes are biologically impoverished, whereas of some low-latitude mountains very complex. Their level species richness is caused by the aggregation many small-ranged species, which has been difficult to explain from purely macroecological models focusing on contemporary ecological processes. Because individual mountain tracts harbor that represent different evolutionary trajectories, it seems plausible relate these assemblages...
Abstract Aim To test whether it is possible to establish a common biogeographical regionalization for plants and vertebrates in sub‐Saharan Africa (the Afrotropical Region), using objective multivariate methods. Location Sub‐Saharan (Afrotropical Region). Methods We used 1° grid cell resolution databases birds, mammals, amphibians snakes (4142 vertebrate species) c . 13% of the (5881 from Region. These were analysed cluster analysis techniques define regions. A β(sim) dissimilarity matrix...
Abstract Despite tremendous efforts in the past decades, relationships among main avian lineages remain heavily debated without a clear resolution. Discrepancies have been attributed to diversity of species sampled, phylogenetic method and choice genomic regions 1–3 . Here we address these issues by analysing genomes 363 bird 4 (218 taxonomic families, 92% total). Using intergenic coalescent methods, present well-supported tree but also marked degree discordance. The confirms that Neoaves...

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...
Large-scale geographical patterns of biotic specialization and the underlying drivers are poorly understood, but it is widely believed that climate plays an important role in determining specialization. As climate-driven range dynamics should diminish local adaptations favor generalization, one hypothesis contemporary determined by degree past climatic instability, primarily Quaternary climate-change velocity. Other prominent hypotheses predict either or species richness affect To gain...
Oscine passerine birds make up almost half of all avian diversity. Relationships within the group, and its classification, have long been controversial. Over last 10 years numerous molecular phylogenies published. We compiled source from 99 published studies to construct an oscine supertree. aimed illustrate weak strong parts phylogeny set targets for future phylogenetic work therefore preferred a heuristic approach where we judged adequacy taxon sampling method each tree instead using...
The rapid global growth of conservation schemes designed to incentivize local communities conserve natural resources has placed new importance on biological monitoring assess whether agreements and targets linked payments are being met. To evaluate competence in resource monitoring, we compared data status trends collected independently by local-community members trained scientists for 63 taxa five types use 34 tropical forest sites across four countries over 2.5 years. We hypothesized that...
Abstract The use of DNA sequence data in systematic studies has brought about a revolution our understanding avian relationships and when combined with digitized distributional data, facilitated new interpretations the origins diverse clades African avifauna including its diversification up through Tertiary until present. Here we review recent special reference to Africa’s forest specifically comment on putative ‘hotspots’ endemism Eastern Arc Mountains Tanzania Cape Region South Africa....
Latitudinal patterns of biodiversity have been studied for centuries, but it is only during the last decades that species interaction networks used to examine proposed latitudinal gradient biotic specialization. These studies given idiosyncratic results, which may either be because genuine biological differences between systems, different concepts and scales quantify specialization or methodological approaches compare were inappropriate. Here we carefully using a global dataset avian...
