Plant Systematics has made a substantial contribution to plant systematics courses at the upper-undergraduate and first year graduate level. This second edition continues to provide the basis for teaching an introduction to the morphology, evolution, and classification of land plants. A foundation of the approach, methods, research goals, evidence, and terminology of plant systematics are presented along with the most recent knowledge of evolutionary relationships of plants and practical information vital to the field. In this second edition, the author includes greatly expanded treatments of families of lycophytes, ferns, gymnosperms, and flowering plants (all with full-color plates), a new chapter on species concepts and the role of systematics in conservation biology, and a new appendix summarizing basic statistical and morphometric techniques used in plant systematics studies. An explanation of maximum likelihood and Bayesian inference algorithms is included in methods of phylogenetic inference, and chapters on morphology and plant nomenclature have been augmented with new material. The second edition of Plant Systematics has been expanded to include: * Fifteen fern families, 9 gymnosperm families, and an increase of angiosperm family treatments from 100 to 129. Each family description includes a plate of full color photographs, illustrating exemplars of the group along with dissected and labeled material to show diagnostic features. * A new chapter on species concepts and the role and impact of plant systematics in conservation biology. * A new appendix on statistical and morphometric techniques in plant systematics. * In addition, the second edition contains more detailed explanations of maximum likelihood and Bayesian phylogeny inference methods, an expanded coverage and glossary of morphological terms, and an updated chapter on botanical nomenclature.

"A major event in botany." -- The New York Times "...will be the definitive work well into the next century." --Library Journal "Flora of North America moves forward steadily, remorselessly, impressively....The level of detail makes the work accessible to a range of users, and the text is clearly written and set out for the non-specialist." -- Plant Talk Volume 5 is the third volume of nineteen on dicots to be published in the Flora of North America series. It treats more than 740 species in 74 genera and three families in the following orders of the subclass Caryophyllidae: Caryophyllales (Pink order); Polygonales (Buckwheat order); and Plumbaginales (Leadwort order). Approximately 60% of the species are endemic to North America north of Mexico, and 19% are known as naturalized elements of the flora. Of the 74 genera treated, 20 are represented in the flora by introduced species, and 13 of the genera have all their species endemic to the region. One of the five largest genera in North America, Eriogonum (Polygonaceae), is represented in the flora area by 225 of its 248 species, with nearly 200 of them endemic. Each of the genera treated in the volume has one or more representative species illustrated with a line drawing. These, in combination with the key and descriptions, will facilitate identification of the group of plants.

Ecophysiology of High Salinity Tolerant Plants

Author: M. Ajmal Khan,Darrell J. Weber

The halophytes are highly specialized plants, which have greater tolerance to salt. They can germinate, grow and reproduce successfully in saline areas which would cause the death of regular plants. Most halophytic species are found in salt marsh systems along seashores or around landlocked inland lakes and flat plains with high evaporation. The halophytes play very significant role in the saline areas specially in the coast by overcoming the salinity in different ways, viz. with regulating mechanisms in which excess salts are excreted and with out regulating mechanism, which may include succulents or cumulative types. Besides that they protect coast from erosion and cyclones, provide feeding ground and nursery for fish, shrimps and birds. Halophytes get increasing attention today because of the steady increase of the salinity in irrigation systems in the arid and semi-arid regions where the increasing population reaches the limits of freshwater availability. In many countries, halophytes have been successfully grown on saline wasteland to provide animal fodder and have the potential for rehabilitation and even reclamation of these sites. The value of certain salt-tolerant grass species has been recognized by their incorporation in pasture improvement programs in many salt affected regions throughout the world. There have been recent advances in selecting species with high biomass and protein levels in combination with their ability to survive a wide range of environmental conditions, including salinity.

Flora of Arequipa, Peru

A Field Guide for Nature Lovers

Author: Edgar Heim

Publisher: BoD – Books on Demand

ISBN: 3735706185

Category: Nature

Page: 128

View: 9292

This field guide illustrates and describes ca. 20% of the recorded 1’160 vascular plants of the department of Arequipa in Southern Peru. It aims to be a comprehensive field guide for tourists and locals. The first part of the book describes the vegetation of Arequipa. It gives an overview of the harsh conditions of south-peruvian ecosystems. Bone-dry deserts and high mountains with extreme temperature fluctuations challenges plant growth. Such ecosystmes demand adaptation by the inhabitants, especially by the plants, which can not escape their habitat. The second part of the book is dedicated to the plant species of the departement of Arequipa. With the illustrations and the description in this book, the reader should be able to recognize the plants in their habitat. Additionally it provides information about the use and the ecology of the described species.

New analytical techniques have enhanced current understanding of the behavior of trace and ultratrace elements in the biogeochemical cycling, chemical speciation, bioavailability, bioaccumulation, and as applied to the phytoremediation of contaminated soils. Addressing worldwide regulatory, scientific, and environmental issues, Trace Elements in the Environment explores these frontiers, including biotechnological aspects of metal-binding proteins and peptides and phytoremediation strategies using trees, grasses, crop plants, aquatics, and risks to ecological and human health. Discussing trace elements in the holistic environment, this book covers advances in state-of-the-art analytical techniques, molecular biotechology, and contemporary biotechnology that enhances knowledge of the behavior of trace elements in the biogeosphere and at the cellular and molecular level. The editors and their hand-picked panel of contributors provide authoritative coverage of trace elements in the environment. They highlight cutting-edge applications of emerging strategies and technologies to the problems of trace elements in the environment. The editors discuss emerging areas such as bacterial biosorption of trace elements, processes, and applications of electroremediation of heavy metals-contaminated soils, application of novel nanoporous sorbents for the removal of heavy metals, metalloids, and radionuclides. The book focuses on the effects of increasing levels of trace elements on ecological and human health, evaluates the effectiveness of methods of phytoremediation, and covers risk assessment, pathways, and trace element toxicity. Containing more than 150 illustrations, tables, photographs, and equations, the book's coverage spans the entire body of knowledge available about how and why plants interact with metals and other trace elements.

Die Horn- und Lebermoose Österreichs : (Anthocerotophyta und Marchantiophyta)

Author: Heribert Köckinger

Publisher: N.A

ISBN: 9783700181538

Category: Hornworts (Bryophytes)

Page: 382

English summary: The present catalogue of hornworts (Anthocerotophyta) and liverworts (Marchantiophyta) is the first synopsis for these two plant kingdom phyla in Austria. As in other volumes of the Catalogus Florae Austriae, there are no keys and no descriptions of genera and species. On the other hand, ecology, phytosociology and distribution of all taxa are treated in detail. In the general part of this catalogue a historical survey and our present state of knowledge of horn- and liverworts in the federal states of the country are presented. A short "hepaticogeography" of Austria highlights the hepaticofloristic characteristics of its climatologically and geomorphologically very different landscapes. In the special part, all species, four hornworts and 260 liverworts, and a series of infraspecific taxa are presented in a uniform conception. Principally, nomenclature and systematics follow the new "World Checklist of Hornworts and Liverworts", apart from a few, reasoned exceptions. The sequence of families is systematical, that of genera alphabetical. Particular attention is given to species distribution, using data obtained from the extensive literature and the collections in public herbaria. In addition, an enormous number of unpublished records were included and many specimens critically revised. Detailed information on ecology and phytosociology rest primarily upon observations in Austria. The general decline of species diversity also affects Austria and its horn- and liverworts. Thus, the growing threats to species and their habitats are evaluated. Optional notes concern taxonomy and other topics. About 140 colour photos illustrate the treatments of selected species of horn- and liverworts. German description: Dieses Nachschlagewerk stellt die erste Synopsis des gesamten Wissens uber die Hornmoose (Anthocerotophyta) und Lebermoose (Marchantiophyta) Osterreichs dar. Der Tradition der Catalogus-Reihe folgend, enthalt es keine Artbeschreibungen oder Bestimmungsschlussel. Stattdessen wird der Okologie, der Soziologie und vor allem der Verbreitung der einzelnen Arten breiter Raum gewahrt. Im allgemeinen Teil wird uber die Erforschungsgeschichte und den aktuellen Kenntnisstand in den einzelnen Bundeslandern informiert. Eine kurze "Hepatikogeographie" Osterreichs charakterisiert die aus klimatischen und geomorphologischen Grunden sehr unterschiedlichen Landschaften Osterreichs anhand ihrer floristischen Besonderheiten. Im speziellen Teil werden alle fur Osterreich nachgewiesenen Arten, vier Hornmoose und 260 Lebermoose, sowie eine Reihe von Unterarten und Varietaten nach einem einheitlichen Muster vorgestellt. Nomenklatur und System richten sich, mit wenigen begrundeten Ausnahmen, nach der neuen "World Checklist of Hornworts and Liverworts". Die Reihung der Familien erfolgt systematisch, jene der Gattungen und Arten hingegen alphabetisch. Grundlage fur die Verbreitungsangaben ist die Auswertung der gesamten Literatur und der offentlichen Sammlungen. Ausserdem konnte eine enorme Zahl unveroffentlichter Funde inkludiert werden, und viele Herbarbelege zu problematischen Meldungen wurden einer Revision unterzogen. Die detaillierten Angaben zur Okologie der Arten und ihrer phytosoziologischen Zugehorigkeit basieren primar auf Beobachtungen im Lande. Fur die Ellenberg-Zeigerwerte der Arten liegt eine vollig neue Bearbeitung vor. Da der zunehmende Artenschwund in Osterreich auch vor den Horn- und Lebermoosen nicht Halt macht, wird jede Art auch hinsichtlich ihrer Gefahrdung im Lebensraum beurteilt. Fakultativ finden sich zudem Anmerkungen zur Taxonomie kritischer Formenkreise und zu anderen Themen. Etwa 140 Farbfotos ausgewahlter Arten illustrieren diesen Katalog.

Renewable Energy Technologies: Their Applications in Developing Countries presents an overview and assessment of technologies for energy-related projects in the rural sector of developing countries. This book discusses the important, but not dominant, role that new and renewable sources of energy (NARSE) will have in the Third World. Bioenergy fuel sources come from wood fuel, energy crops, agricultural residue and organic wastes, peat, biomass briquettes, biogas, and animal power. The text also describes the problems related to operating biomass engines and to the production of engine fuels such as alcohol fuels, vegetable oil, producer gas made from wood and charcoal. These problems concern land use and site location for growing these fuel crops, government policies or subsidies, as well as competition with prevailing petrol prices. Solar water heaters and photovoltaic cells can be used by households and in bigger institutions; ongoing technological developments mainly focus on cutting down costs and better manufacturing methods. The book also addresses other NARSE such as hydro, wind, and water power generation. This book is suitable for economists, environmentalists, ecologists, and policy makers involved in energy conservation and rural development.
