This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fernanda Antunes Carvalho addresses an issue of key importance to the field of systematics, namely how to foster taxonomic work and the dissemination of scientific knowledge about species by taking full advantage of electronic data and bioinformatics tools. The first part focuses on the development of an electronic monograph of the papaya family (Caricaceae) using existing infrastructures of Information Technology (IT) and bioinformatic tools that together set the stage for a new era of systematics. Based on the plastid and nuclear DNA data, the author inferred historical processes in the second part that may have shaped the evolution of the Caricaceae and explain their current geographic distribution. The last part is dedicated to the evolution of chromosome numbers in the Caricaceae and includes counts for species from three genera (Cylicomorpha, Horovitzia, Jarilla) that have never been investigated before.

Download or read book Phylogeny and Biogeography of Neotropical Flowering Plant Tribe Citharexyleae Verbenaceae written by Laura A. Frost and published by . This book was released on 2018 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: The New World tropics, or Neotropics, located within tropical latitudes of North and South America, are one of the most diverse ecoregion in the world. However, this diversity is poorly understood in terms of described biodiversity—species numbers are uncertain and collection records are depauperate for many groups distributed in remote locations or dense forest—and patterns of evolution contributing to high diversity—factors underlying speciation in lineages are not well understood. A molecular phylogenetic and systematic study of the Neotropical flowering plant tribe Citharexyleae in the Verbena family (Verbenaceae), which also originated and diversified primarily in the Neotropics, was undertaken in order to describe diversity and understand patterns of evolution in an understudied Neotropical lineage. Chapter 1 comprises a systematic study of tribe Citharexyleae, which describes relationships between the three genera in the tribe (Baillonia (1 species), Citharexylum (ca. 70 species), and Rehdera (2 species)) as well as relationships within Citharexylum, the largest genus. Baillonia is included in Citharexylum and Rehdera is retained distinct. A subgeneric classification including six subgenera system is proposed for Citharexylum, and morphological characters associated with each major clade described. In Chapter 2, the biogeographical patterns underpinning diversification in Citharexylum are explored. Citharexylum comprises ca. 70 species distributed widely throughout the Neotropics, from northern Mexico to southern Brazil and Argentina. Species occupy multiple biomes including continuously moist broadleaf forest, seasonally dry tropical forest, tropical coniferous forest, high elevation shrublands, and arid shrublands. The contributions of radiation within a biome and adaptation to/colonization of new biomes are compared. Both patterns have played important roles in the diversification of Citharexylum, and major lineages within Citharexylum display different patterns. The Mesoamerican clade exhibits a pattern of radiation within the ancestral biome with more recent, independent colonization events, whereas the South American clade exhibits a pattern of early colonization and radiation within biomes. Though diversification rates are higher in the Mesoamerican clade, both clades have produced similar taxonomic diversity in the same amount of time. Both patterns contribute equally to overall diversity in the genus. Chapter 3 incorporates molecular sequence data generated by the previous chapters with data generated in previous studies other lineages of Verbenaceae and newly generated data to produce an updated phylogeny of the Verbena family. Verbenaceae comprises ca. 770 species in 28 genera. A previous family-wide study sampled 7 chloroplast regions for 121 species. The expanded dataset encompasses twelve chloroplast regions, two nuclear ribosomal spacers, and eight low-copy nuclear loci for 366 species. Two new clades in Verbenaceae are described, including resurrection of the genus Scleröon Benth in Lindl.
Download or read book Phylogeny Biogeography and Systematics of Branchipolynoe Polynoidae Annelida with Descriptions of Four New Species from Costa Rican Methane Seeps written by Johanna Irene Lindgren and published by . This book was released on 2017 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are currently four named species of Branchipolynoe, all found living symbiotically in mytilid mussels in the genus Bathymodiolus, which all occur at hydrothermal vents or methane seeps. Here, phylogenetic analyses using mitochondrial (CO1 and 16S) and nuclear (ITS) genes, as well as morphological analysis were conducted on a collection of Branchipolynoe from Pacific Costa Rican methane seeps. This revealed four new species of Branchipolynoe and these are formally described here. These newly discovered species live in three different species of Bathymodiolus mussels (also new) at depths ranging from 1000 m to 1800 m. Branchipolynoe kajsae sp. nov. and Branchipolynoe halliseyae sp. nov. are found in hosts Bathymodiolus billschneideri, B. earlougheri, and B. nancyschneiderae. Branchipolynoe meridae sp. nov. is found in hosts Bathymodiolus earlougheri and B. billschneideri. Branchipolynoe eliseae sp. nov. is found in hosts Bathymodiolus billschneideri and B. nancyschneiderae. The phylogenetic and biogeographical implications of this high sympatric diversity of Branchipolynoe are discussed.

Download or read book Phylogeny Biogeography and Systematics of Menodora oleaceae and the Chloroplast Genome of Pelargonium Hortorum written by Timothy Wayne Chumley and published by . This book was released on 2007 with total page 840 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents the result of two separate research programs. The first elucidates the phylogeny, biogeography and systematics of the genus Menodora in the olive family. A phylogeny based on the internal transcribed spacer (ITS) of nuclear ribosomal DNA and the chloroplast rps16 and trnL introns and trnL-F intergenic spacer demonstrates that the genus is monophyletic. Within the genus, M. robusta of Patagonia is the first taxon to branch, followed by a monophyletic African clade and M. spinescens of California, though the placement of the latter does not have strong support. Most North American species are nested within the derived South Americans. A South American origin is hypothesized, with two independent dispersals to North America, and a single dispersal to Africa. The phylogeny provided new insights for the systematic treatment, where 24 species, one subspecies and six varieties are recognized, with major realignments of the intregrifolia and scabra species complexes, and a single new species described. In the second area of research, the chloroplast genome of Pelargonium × hortorum has been completely sequenced. At 217,942 base pairs (bp), it is both the largest and most rearranged land plant chloroplast genome yet sequenced. It features two copies of a greatly expanded inverted repeat (IR) of 75,741 bp each, and diminished single copy regions of 59,710 bp and 6,750 bp. Gene content is similar to other angiosperms, with the exceptions of a large number of pseudogenes, two open reading frames (ORF56 and ORF42), and the losses of accD, trnT-ggu, and possibly rpoA. The latter may be represented, however, by highly divergent set of rpoA-like ORFs. The IR expansion accounts for most of the size increase of the genome, but an additional 10% is related to the large number of repeats found. Most of these occur near rearrangement hotspots, and two different repeat associations (characterized by full or partial duplications of several genes) are localized in these regions. We propose simple models that account for the major rearrangements with a minimum of eight IR boundary changes and 12 inversions in addition to several sequence duplications.
Download or read book Multi pronged Approach to Eastern North American Biogeography written by Ashley Brigham Morris and published by . This book was released on 2006 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Eastern North America is both geologically and ecologically complex, and this complexity has led to an equally complicated biogeographic history, particularly in recent geologic times, that remains unresolved. The two primary issues of debate have been 1) the location of full glacial refugia for temperate plant species, and 2) the timing of the origin of the disjunct temperate floral element of the mountains of eastern Mexico. This research addressed these two issues using three exemplar genera that share the Mexican disjunction: Illicium, Fagus, and Liquidambar. A molecular phylogeny of Illicium using ITS and plastid sequence data found support for monophyletic New World and Old World clades. The relationship between the two New World ligulate species, I. floridanum and I. mexicanum, was well-supported, and divergence time estimates based on fossil calibration date this split to be approximately one to three million years old, which is consistent with the arrival of other temperate woody genera in Mexico based on fossil pollen records. Phylogeographic data for Fagus and Liquidambar based on plastid sequences show little or no variation between Mexican individuals and those from U.S. populations. The greatest divergence within each species occurs within the U.S., and the geographic distribution of haplotype variation suggests multiple refugial locations for each: Lower Mississippi River Valley/Interior Highlands and Eastern Gulf Coast/Southern Appalachians for Fagus; Interior Highlands/Cumberland Plateau/Southern Appalachians and peninsular Florida for Liquidambar. Divergence time estimates for Liquidambar based on previously published fossil calibrations suggest that the phylogeographic breaks recovered here may pre-date the last glaciation. Finally, bioclimatic modeling may not be a feasible tool for predicting present and future haplotype distribution in species where sharp phylogeographic breaks are absent.

Download or read book The Flowering Plants Handbook written by James W. Byng and published by Plant Gateway Ltd.. This book was released on 2014-10-16 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: This plant book aims to help identify flowering plants to genus and family level anywhere in the world. In 2014 there were very few available works which were both comprehensive and up-to-date for all the flowering plants families and genera of the world. The Flowering Plants Handbook is an easy to use identification guide to the worlds flowering plants designed for both specialists and non-specialists and from beginner to expert. The book contains descriptions of all currently recognised flowering plant families, morphological notes for 6656 genera (all current genera for 398/413 families) and over 3000 images and illustrations. Flowering plants can be identified using the book to family and much of the world's generic diversity in four 'easy' steps. Some plants will be identified correctly quickly, whilst others may require some retracing of steps and take a little more time. The advantage of this book is that it helps the user learn about the classification system and plant diversity during the identification process. This work was compiled and developed using the living, library and herbarium collections at the University of Aberdeen, Royal Botanic Gardens, Edinburgh and Royal Botanic Gardens, Kew.
