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. Contents Taxonomy in the Electronic Age Correct Names for Some of the Closest Relatives of Carica Papaya A Dated Phylogeny of the Papaya Family Chromosome Counts for the Caricaceae Reveal Target Groups Researchers and students in the field of plant taxonomy as well as biogeographers The Author Dr. Fernanda Antunes Carvalho completed her Ph.D. in Botany at the Ludwig-Maximilians-Universität München, Germany.

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 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.

Available in PDF, EPUB and Kindle. Book excerpt: This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.
