Significance Large floristic datasets that purportedly represent the diversity and composition of Amazon tree flora are being widely used to draw conclusions about patterns evolution plant diversity, but these fundamentally flawed in both their methodology resulting content. We have assembled a comprehensive dataset Amazonian seed species from published sources includes falsifiable data based on voucher specimens identified by taxonomic specialists. This growing list should serve as basis...
The sunflower family, Asteraceae, comprises 10% of all flowering plant species and displays an incredible diversity form. Asteraceae are clearly monophyletic, yet resolving phylogenetic relationships within the family has proven difficult, hindering our ability to understand its origin diversification. Recent molecular clock dating suggested a Cretaceous origin, but lack deep sampling many genes representative taxa from across impeded resolution migration routes diversifications that led...
• Premise of the study: The Compositae (Asteraceae) are a large and diverse family plants, most comprehensive phylogeny to date is meta‐tree based on 10 chloroplast loci that has several major unresolved nodes. We describe development an approach enables rapid sequencing numbers orthologous nuclear facilitate efficient phylogenomic analyses. Methods Results: designed set sequence capture probes target conserved sequences in Compositae. also developed bioinformatic phylogenetic workflow for...
Abstract Discoveries from collections‐based science change the way we perceive ourselves, our environment, and place in universe. The 18 th Century saw beginning of formal classification with Linnaeus proposing a system to classify all life. 19 ushered age exploration as naturalists undertook large‐scale collecting expeditions leading major scientific advances (the founding Physical Geography, Meteorology, Ecology, Biogeography, Evolution) challenging long held beliefs about nature. In 20...
Hybridization is an important part of the evolutionary history flowering plants. If hybridization has occurred among species a taxon under cladistic analysis results are varied but always present additional difficulties. in incongruent intersecting data that obscure underlying hierarchy. Guidelines and methods examined for their usefulness identifying possible hybrids study. Seven genera analyzed cladistically resulting cladograms hybrids. These hypotheses then compared to other data, such...
Abstract Systematic biology is a discipline rooted in collections. These collections play important roles research and conservation are integral to our efforts educate society about biodiversity conservation. Collections provide an invaluable record of the distribution organisms throughout world through recent geological time, they only direct documentation biological, physical, cultural diversity planet: past, present, future. Recent developments bioinformatics cyberinfrastructure...
Systematic data in the form of collections are useful biodiversity studies many ways, most importantly because they serve as only direct evidence species distributions. However, collecting bias has been demonstrated for areas world and led some to propose methods that circumvent need data. New model combination with abiotic predict potential total distribution examined using 25,111 records representing 5,123 plants animals from Guyana; use reduced number 320 species. These modeled...
Abstract Aim To estimate the rate of adaptive radiation endemic Hawaiian Bidens and to compare their diversification rates with those other plants in Hawaii elsewhere rapid radiation. Location Hawaii. Methods Fifty‐nine samples representing all 19 species, six subspecies, two hybrids an additional Central American African species had DNA extracted, amplified by polymerase chain reaction sequenced for four chloroplast nuclear loci, resulting a total approximately 5400 base pairs per...
The Nomenclature Section held just before the 18th International Botanical Congress in Melbourne, Australia July 2011 saw sweeping changes to way scientists name new plants, algae, and fungi. begin on cover: title was broadened make explicit that Code applies not only but also algae will now be of fungi, plants. For first time history allow for electronic publication names taxa. In an effort more accurate efficient, requirement a Latin validating diagnosis or description changed either...
Abstract Comprising more than 25 000 species, the Sunflower Family (Compositae or Asteraceae) is largest family of flowering plants. Many its lineages have experienced recent and rapid radiations, has a deep widespread history large‐scale gene duplications polyploidy. most important evolutionary questions about family's diversity remain unanswered due to poor resolution lack support for major nodes phylogeny. Our group employed phylogenomics approach using Hyb‐Seq that includes sequencing...
Summary The global flora is thought to contain a large proportion of herbs, and understanding the general spatiotemporal processes that shaped distribution these communities one most difficult issues in biogeography. We explored patterns world‐wide biogeography species‐rich herbaceous group, paper daisy tribe Gnaphalieae (Asteraceae), based on hitherto largest taxon sampling, total 835 terminal accessions representing 80% genera, encompassing geographic range tribe, with nuclear internal...
