Significance Amazonia is not only the world’s most diverse rainforest but also region in tropical America that has contributed to its total biodiversity. We show this by estimating and comparing evolutionary history of a large number animal plant species. find there been extensive interchange lineages among different regions biomes, over course tens millions years. stands out as primary source diversity, which can be mainly explained amount time Amazonian have occupied region. The...
The tropical Andes of South America, the world's richest biodiversity hotspot, are home to many rapid radiations. While geological, climatic, and ecological processes collectively explain such radiations, their relative contributions seldom examined within a single clade. We explore contribution these factors by applying series diversification models that incorporate mountain building, climate change, trait evolution first dated phylogeny Andean bellflowers (Campanulaceae: Lobelioideae). Our...
The increase in species richness from the poles to tropics, referred as latitudinal diversity gradient, is one of most ubiquitous biodiversity patterns natural world. Although understanding how rates speciation and extinction vary with latitude central explaining this pattern, such analyses have been impeded by difficulty estimating diversification associated specific geographic locations. Here, we use a powerful phylogenetic approach nearly complete phylogeny mammals estimate speciation,...
Summary A number of approaches for studying macroevolution using phylogenetic trees have been developed in the last few years. Here, we present RPANDA , an R package that implements model‐free and model‐based comparative methods macroevolutionary analyses. The implemented are recently stemming from graph theory allow summarizing information contained trees, computing distances between clustering them accordingly. They also identifying distinct branching patterns within single trees....
Predicting how biodiversity will be affected and respond to human-induced environmental changes is one of the most critical challenges facing ecologists today. Here, we put current their effects on in a macroevolutionary perspective. We build research palaeontology recent developments phylogenetic approaches ask macroevolution can help us understand have past, they affect future. More more paleontological data are accumulated, argue that much potential these for understanding remains explored.
Ecology Letters (2012) Abstract The latitudinal diversity gradient (LDG) is one of the most striking ecological patterns on our planet. Determining evolutionary causes this pattern remains a challenging task. To address issue, previous LDG studies have usually relied correlations between environmental variables and species richness, only considering processes indirectly. Instead, we use phylogenetically integrated approach to investigate responsible for global observed in swallowtail...
Xenarthra (armadillos, sloths, and anteaters) constitutes one of the four major clades placental mammals. Despite their phylogenetic distinctiveness in mammals, a reference phylogeny is still lacking for 31 described species. Here we used Illumina shotgun sequencing to assemble 33 new complete mitochondrial genomes, establishing as first clade be fully sequenced at species level mitogenomes. The resulting data set allowed reconstruction robust framework timescale that are consistent with...
Bayesian relaxed-clock dating has significantly influenced our understanding of the timeline biotic evolution. This approach requires use priors on branching process, yet little is known about their impact divergence time estimates. We investigated effect using iconic cycads. conducted phylogenetic estimations for 237 cycad species three genes and two calibration strategies incorporating up to six fossil constraints (i) test different process age estimates, (ii) assess which prior better...
Summary The Andean mountains of South America are the most species‐rich biodiversity hotspot worldwide with c . 15% world's plant species, in only 1% land surface. Orchids a key element flora, and one prominent components Neotropical epiphyte diversity, yet very little is known about their origin diversification. We address this knowledge gap by inferring biogeographical history diversification dynamics two largest orchid groups (Cymbidieae Pleurothallidinae), using unparalleled, densely...
Significance Competition for common resources can make some species groups thrive and others decline. Flowering plants rose to dominance between 125 80 Ma, undergoing an explosive radiation that is believed have impacted long-established plant like gymnosperms. Here, we show the decline of conifers strongly directly linked increasing diversity flowering plants. Both fossil record molecular data converge in clarifying effects abiotic or biotic factors on speciation extinction rates conifers....
Butterflies are a diverse and charismatic insect group that thought to have evolved with plants dispersed throughout the world in response key geological events. However, these hypotheses not been extensively tested because comprehensive phylogenetic framework datasets for butterfly larval hosts global distributions lacking. We sequenced 391 genes from nearly 2,300 species, sampled 90 countries 28 specimen collections, reconstruct new phylogenomic tree of butterflies representing 92% all...
Orchids constitute one of the most spectacular radiations flowering plants. However, their origin, spread across globe, and hotspots speciation remain uncertain due to lack an up-to-date phylogeographic analysis. We present a new Orchidaceae phylogeny based on combined high-throughput Sanger sequencing data, covering all five subfamilies, 17/22 tribes, 40/49 subtribes, 285/736 genera, c. 7% (1921) 29 524 accepted species, use it infer geographic range evolution, diversity, patterns by adding...
Interactions with angiosperms have been hypothesised to play a crucial role in driving diversification among insects, particular emphasis on pollinator insects. However, support for coevolutionary insect-plant interactions is weak. Macroevolutionary studies of insect and plant diversities the hypothesis that diversified after peak diversity Early Cretaceous. Here, we used family-level fossil record insects as whole, families particular, estimate rates macroevolutionary history using Bayesian...
Macroevolutionary studies of insects at diverse taxonomic scales often reveal dynamic evolutionary patterns, with multiple inferred diversification rate shifts. Responses to major past environmental changes, such as the Cretaceous Terrestrial Revolution, or development key innovations, wings complete metamorphosis are usually invoked potential triggers. However this view is partially contradicted by on family-level fossil record showing that insect was relatively constant through time. In an...
How seasonal migration originated and impacted diversification in birds remains largely unknown. Although migratory behaviour is likely to affect bird diversification, previous studies have not detected any effect. Here, we infer ancestral the effect of on speciation extinction dynamics using a complete tree life. Our analyses that sedentary ancestral, evolved independently multiple times during evolutionary history birds. Speciation species into two daughter more frequent than species....
The previously recognised closely related species Graphium (Pazala) mandarinus (Oberthür, 1879) and G. (P.) sichuanica (Koiwaya, 1993) are shown to comprise seven as a result of both molecular morphological analysis. Molecular dating analysis is also performed on the group in order investigate divergence time taxa. Two taxa, garhwalica (Katayama, 1988) stat. nov. paphus (de Nicéville, 1886) nov., raised from subspecific specific status; hoeneanus Cotton Hu nom. rev. separated at level; two...
The Graphium (Pazala) mandarinus group was recently defined and the status of taxa as well number species revised. We report here discovery a new from Kon Tum plateau Truong Son (Annamite) Range Central Vietnam, which we describe based on morphological molecular evidence. Molecular phylogeny shows that taxon, G. (P.) wenlingae Hu, Cotton & Monastyrskii sp. nov., is sister to daiyuanae Zhang Cotton, 2018 plus confucius Duan 2018. dating analysis further suggests this diverged its clade in...
Abstract Evolutionary relationships have remained unresolved in many well-studied groups, even though advances next-generation sequencing and analysis, using approaches such as transcriptomics, anchored hybrid enrichment, or ultraconserved elements, brought systematics to the brink of whole genome phylogenomics. Recently, it has become possible sequence entire genomes numerous nonbiological models parallel at reasonable cost, particularly with shotgun sequencing. Here, we identify...
Significance Many lineages increase in diversity through time, and some of them eventually decline get replaced. The causes such remain elusive are especially difficult to understand over a long-time scale global distribution. Relying on unprecedented species-level fossil datasets spanning the last 140 million years, we investigated wax wane mackerel sharks (Lamniformes), including great white shark. We find that both temperature competition with ecologically similar members their sister...
Three Graphium species belonging to two groups of the subgenus Pazala, alebion and tamerlanus groups, were examined in molecular morphological studies, their female genitalia are reported for first time. Their relationship with other within is assessed divergence times estimated. We find that G. (P.) lineage diverge Pazala early Miocene (20 Ma) parus sister diverged from each late (7 Ma). A revision four recognised taxa three presented, historical misidentification these geographic ranges explained.
Global biodiversity currently peaks at the equator and decreases toward poles. Growing fossil evidence suggest this hump-shaped latitudinal diversity gradient (LDG) has not been persistent through time, with similar across latitudes flattening out LDG during past greenhouse periods. However, when how declined high to generate modern remains an open question. Although diversity-loss scenarios have proposed, they remain mostly undemonstrated. We outline "asymmetric of extinction dispersal"...
The question why non-avian dinosaurs went extinct 66 million years ago (Ma) remains unresolved because of the coarseness fossil record. A sudden extinction caused by an asteroid is most accepted hypothesis but it debated whether were in decline or not before impact. We analyse speciation-extinction dynamics for six key dinosaur families, and find a across dinosaurs, where diversification shifted to declining-diversity pattern ~76 Ma. investigate influence ecological physical factors, that...
