Download or read book A Field Guide to Tropical Plant Families written by Roland Keller and published by Springer Nature. This book was released on 2023-03-12 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an identification system permitting recognition of plant families in all seasons by means of morphological and macroanatomical features which are easily observable, such as bark, exudates, stems and leaves characters. Studies of forest vegetation may differ in their underlying objectives, but they all require taxonomic knowledge. The process of taxonomy begins with an inventory of the flora, which has been based to a large extent on reproduction-related organs, such as flowers and fruits. But, those are often difficult to observe and may not exist in the field at a given time. Unlike most such guides or keys, this book can be used anywhere in the tropics and provides, in a straightforward two or three-step process, identification to the level of families, which are now circumscribed according to molecular as well as morphological characters in the universally accepted scheme of the Angiosperm Phylogeny Group. Plant architecture is not a prerequisite theme for plant identification; however, we think that an introduction to this subject is not out of place in this book (architectural traits are taxonomically sound): it is now time for botanists working in the tropics to have an idea on how the whole organism keeps growing. Within the family accounts, there is information concerning important economic plants with notes on the larger genera and, particularly helpfully, discussion of families readily confused and how to separate them. Descriptions of the families rely on short diagnosis bolstered by many photographic pictures, lines drawings and extracts from the author’s field books, all showing features of plants as they are found in the forest.

Download or read book Phylogeny and Evolution of the Angiosperms written by Douglas Soltis and published by University of Chicago Press. This book was released on 2018-01-24 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although they are relative latecomers on the evolutionary scene, having emerged only 135?170 million years ago, angiosperms—or flowering plants—are the most diverse and species-rich group of seed-producing land plants, comprising more than 15,000 genera and over 350,000 species. Not only are they a model group for studying the patterns and processes of evolutionary diversification, they also play major roles in our economy, diet, and courtship rituals, producing our fruits, legumes, and grains, not to mention the flowers in our Valentine’s bouquets. They are also crucial ecologically, dominating most terrestrial and some aquatic landscapes. This fully revised edition of Phylogeny and Evolution of the Angiosperms provides an up-to-date, comprehensive overview of the evolution of and relationships among these vital plants. Incorporating molecular phylogenetics with morphological, chemical, developmental, and paleobotanical data, as well as presenting a more detailed account of early angiosperm fossils and important fossil information for each evolutionary branch of the angiosperms, the new edition integrates fossil evidence into a robust phylogenetic framework. Featuring a wealth of new color images, this highly synthetic work further reevaluates long-held evolutionary hypotheses related to flowering plants and will be an essential reference for botanists, plant systematists, and evolutionary biologists alike.

Download or read book The Ornaments of Life written by Theodore H. Fleming and published by University of Chicago Press. This book was released on 2013-10-03 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: The average kilometer of tropical rainforest is teeming with life; it contains thousands of species of plants and animals. As The Ornaments of Life reveals, many of the most colorful and eye-catching rainforest inhabitants—toucans, monkeys, leaf-nosed bats, and hummingbirds to name a few—are an important component of the infrastructure that supports life in the forest. These fruit-and-nectar eating birds and mammals pollinate the flowers and disperse the seeds of hundreds of tropical plants, and unlike temperate communities, much of this greenery relies exclusively on animals for reproduction. Synthesizing recent research by ecologists and evolutionary biologists, Theodore H. Fleming and W. John Kress demonstrate the tremendous functional and evolutionary importance of these tropical pollinators and frugivores. They shed light on how these mutually symbiotic relationships evolved and lay out the current conservation status of these essential species. In order to illustrate the striking beauty of these “ornaments” of the rainforest, the authors have included a series of breathtaking color plates and full-color graphs and diagrams.

Download or read book The Duckweed Genomes written by Xuan Hieu Cao and published by Springer Nature. This book was released on 2020-01-07 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book tells the story behind the first Spirodela genome sequencing project. Further, it describes the current genomics applications of these findings, and efforts to sequence new genomes within the family. The closing chapters address the sequencing of the over 1 Gigabase Wolffia genomes, which could have major impacts on genome evolution and agricultural research. The duckweed or Lemnaceae family is a collection of 5 genera and 37 species of the smallest, fastest-growing flowering plants. Many of these aquatic monocotyledonous plants can grow all over the world, in a variety of climates. Given their simplified and neotenous morphology, duckweeds have been researched for several decades as a model species for plant physiology and ecotoxicological research, contributing to our understanding e.g. of flowering response, plant circadian systems, sulfur assimilation pathways and auxin biosynthesis. In addition, duckweed-based treatment has been a favorite and feasible means, especially in developing countries, of removing phosphorus and pharmaceutical chemicals from sewage and wastewater. With a dry annual mass yield per hectare of up to 80 tonnes (equivalent to 10 tonnes of protein), duckweed is also a promising aquatic crop in new modern and sustainable agriculture. Besides being an excellent primary or supplemental feedstock for the production of livestock and fish, duckweed biomass can be utilized as a potential resource for human nutrition, biofuel, or bioplastics, depending on water quality as well as protein or starch accumulating procedures. These academic and commercial interests have led to international efforts to sequence the Spirodela polyrhiza genome, the smallest and most ancient genome in the family.

Download or read book The Routledge International Handbook of Island Studies written by Godfrey Baldacchino and published by Routledge. This book was released on 2018-06-13 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: From tourist paradises to immigrant detention camps, from offshore finance centres to strategic military bases, islands offer distinct identities and spaces in an increasingly homogenous and placeless world. The study of islands is important, for its own sake and on its own terms. But so is the notion that the island is a laboratory, a place for developing and testing ideas, and from which lessons can be learned and applied elsewhere. The Routledge International Handbook of Island Studies is a global, research-based and pluri-disciplinary overview of the study of islands. Its chapters deal with the contribution of islands to literature, social science and natural science, as well as other applied areas of inquiry. The collated expertise of interdisciplinary and international scholars offers unique insights: individual chapters dwell on geomorphology, zoology and evolutionary biology; the history, sociology, economics and politics of island communities; tourism, wellbeing and migration; as well as island branding, resilience and ‘commoning’. The text also offers pioneering forays into the study of islands that are cities, along rivers or artificial constructions. This insightful Handbook will appeal to geographers, environmentalists, sociologists, political scientists and, one hopes, some of the 600 million or so people who live on islands or are interested in the rich dynamics of islands and island life.
