Describing Species: Practical Taxonomic Procedure for Biologists

New species are discovered every day—and cataloguing all of them has grown into a nearly insurmountable task worldwide. Now, this definitive reference manual acts as a style guide for writing and filing species descriptions. New collecting techniques and new technology have led to a dramatic increase in the number of species that are discovered. Explorations of unstudied regions and new habitats for almost any group of organisms can result in a large number of new species discoveries—and hence the need to be described. Yet there is no one source a student or researcher can readily consult to learn the basic practical aspects of taxonomic procedures.Species description can present a variety of difficulties: Problems arise when new species are not given names because their discoverers do not know how to write a formal species description or when these species are poorly described. Biologists may also have to deal with nomenclatural problems created by previous workers or resulting from new information generated by their own research. This practical resource for scientists and students contains instructions and examples showing how to describe newly discovered species in both the animal and plant kingdoms.With special chapters on publishing taxonomic papers and on ecology in species description, as well as sections covering subspecies, genus-level, and higher taxa descriptions, Describing Species enhances any writer's taxonomic projects, reports, checklists, floras, faunal surveys, revisions, monographs, or guides.The volume is based on current versions of the International Codes of Zoological and Botanical Nomenclature and recognizes that systematics is a global and multicultural exercise. Though Describing Species has been written for an English-speaking audience, it is useful anywhere Taxonomy is spoken and will be a valuable tool for professionals and students in zoology, botany, ecology, paleontology, and other fields of biology.

Describing Species: Practical Taxonomic Procedure for Biologists

A basic practical manual for the process of describing new species, this desperately needed desk reference and guide to nomenclatural procedure and taxonomic writing serves as a Strunk & White of species description, covering both botanical and zoological codes of nomenclature.

Descriptive Archaeoastronomy and Ancient Indian Chronology

This book presents the basic fundamentals of descriptive archaeoastronomy and its application to the astronomical descriptions found in ancient Indian scriptures. Archaeoastronomy is a branch of positional astronomy that helps to determine the epochs of ancient astronomical alignments and special astronomical events. In this book, only the descriptions of special stellar alignments and events found in ancient texts can identify the antiquity of the descriptions. India possesses a large volume of ancient scriptures like Vedas and Puranas which contain many astronomical descriptions as in ancient India positional astronomy was well developed. The antiquities of these texts are determined through archaeoastronomical techniques. Major events like Mahabharata War are dated and using these dates a chronology of ancient India is determined. The astronomically determined chronology is compared with the results from various archaeological, palaeoclimatological, geological and genealogical investigations of ancient India. This introductory book interests readers interested in unveiling the mystery involved with the protohistory of this ancient civilization.

Descriptive Inorganic, Coordination, and Solid State Chemistry

This proven book introduces the basics of coordination, solid-state, and descriptive main-group chemistry in a uniquely accessible manner, featuring a "less is more" approach. Consistent with the "less is more" philosophy, the book does not review topics covered in general chemistry, but rather moves directly into topics central to inorganic chemistry. Written in a conversational prose style that is enjoyable and easy to understand, this book presents not only the basic theories and methods of inorganic chemistry (in three self-standing sections), but also a great deal of the history and applications of the discipline. This edition features new art, more diversified applications, and a new icon system. And to better help readers understand how the seemingly disparate topics of the periodical table connect, the book offers revised coverage of the author's "Network of Interconnected Ideas" on new full color endpapers, as well as on a convenient tear-out card.

Descriptive Taxonomy

In an age when biodiversity is being lost at an unprecedented rate, it is vital that floristic and faunistic information is up to date, reliable and easily accessible for the formulation of effective conservation strategies. Electronic data management and communication are transforming descriptive taxonomy radically, enhancing both the collection and dissemination of crucial data on biodiversity. This volume is written by scientists at the forefront of current developments of floras and faunas, along with specialists from applied user groups. The chapters review novel methods of research, development and dissemination, which aim to maximise the relevance and impact of data. Regional case studies are used to illustrate the outputs and impacts of taxonomic research. Integrated approaches are presented which have the capacity to accelerate the production of floras and faunas and to better serve the needs of a widening audience.

Desde la eternidad hasta hoy: En busca de la teoría definitiva del tiempo

A partir de la entropía, la física cuántica, los viajes en el tiempo o el significado de la vida, Sean Carroll profundiza en uno de los grandes enigmas de la ciencia: ¿Qué es el tiempo? Hace veinte años Stephen Hawking intentó explicar el tiempo a través de la comprensión del big bang. Ahora, en Desde la eternidad hasta hoy, Sean Carroll, uno de los mejores físicos teóricos del mundo, nos ofrece una teoría revolucionaria que ilustra cómo la flecha del tiempo existe gracias a condiciones previas al big bang, una era con la que Einstein ni siquiera soñó, y que explica que nuestro universo convive con universos paralelos en los que el tiempo viaja en dirección opuesta. Autoridades en el campo de la física teórica opinan... «Una exploración cautivadora de los misterios del tiempo.» Brian Green «Lúcido y profundo.» Kip S. Thome Y la prensa afirma... «Desde la eternidad hasta hoy es una de las mejores explicaciones de los misterios asombrosos de nuestro universo.» The Wall Street Journal «Carroll utiliza un lenguaje coloquial y accesible para explorar los desafíos de la cosmología.» Library Journal

Desde las ruinas del futuro

Si queremos evitar futuros sobresaltos, es necesario explicar la crisis y elucidar sus significados. La pandemia de la COVID-19 ha sacudido a la humanidad con una fuerza inopinada: un virus de origen animal ha obligado a los ciudadanos de gran parte del globo a quedarse en casa, y el mundo acelerado de la globalización se ha detenido ante la mirada perpleja de los contemporáneos. Millones de personas han enfermado y cientos de miles han muerto, mientras el uso masivo de las mascarillas nos recordaba a diario que la habitabilidad del planeta no puede darse por supuesta. Así que, un siglo después de la Gripe Española, otro virus infeccioso ha actuado como agente histórico de primer orden. Y esta catástrofe inesperada, mas no imprevista, aguarda ahora a sus intérpretes. Manuel Arias Maldonado se aproxima a la pandemia como al fenómeno polisémico que es: efecto colateral de las relaciones socionaturales y riesgo global que a duraspenas encaja en las categorías dominantes; la acción del virus fuerza a las democracias a operar en condiciones excepcionales dominadas por la incertidumbre. Pero el virus también activa nuevos imaginarios colectivos y reabre el debate sobre un futuro que se presenta menos como promesa que como amenaza. Rehuyendo cualquier tentación profética, el autor defiende la capacidad del viejo pensamiento ilustrado para procesar con éxito este acontecimiento sublime, cuya causa no debe buscarse en el fracaso de la modernidad sino en su carácter asimétrico e inacabado. La crítica ha dicho sobre el autor:«Leer a Arias Maldonado siempre nos ayuda a entender cómo está cambiando el mundo.»Daniel Gascón, Letras Libres «Arias Maldonado no es un politólogo sino un filósofo político. La diferencia entre ambos oficios es la misma que separa al interiorista del arquitecto. Arias es un académico cuya kantiana ambición es toda la que quepa en la consideración científica de la política. Su trabajo trasciende el corral patrio para dialogar con homólogos extranjeros sobre desafíos estructurales de la democracia occidental.»Jorge Bustos, El Cultural

The Desert Bones: The Paleontology and Paleoecology of Mid-Cretaceous North Africa (Life of the Past)

An essential introduction to the age of dinosaurs in Africa.Once Africa was referred to as the ''Lost World of the dinosaur era,'' so poorly known were its ancient flora and fauna. Worse still, many priceless fossil specimens from the Sahara Desert were destroyed during the Second World War. Fortunately, in the twentieth-first century, more researchers are now working in north Africa than ever before and making fascinating discoveries such as the dinosaur Spinosaurus. Based on a decade of study, The Desert Bones brings the world of African dinosaurs fully into the light. Jamale Ijouiher skillfully draws on the latest research and knowledge about paleoecology to paint a compelling and comprehensive portrait of the mid-Cretaceous in North Africa.

Desert Navigator: The Journey of the Ant

Cataglyphis ants can set out across vast expanses of desert terrain in search of prey, and then find the shortest way home. Rüdiger Wehner has devised elegant experiments to unmask how they do it. Through a lively and lucid narrative, he offers a firsthand look at the extraordinary navigational skills of these charismatic creatures.

Desert Plants

Vast areas of Earth's landmass exist as deserts, representing quite distinct ecosystems. Desert plants and animals have evolved specialised survival strategies to cope with the harsh environment of high temperatures and scarce water resources. The life-supporting vegetation of deserts is characterised by its unique reproductive biology, metabolism and adaptive characters. Plants like Prosopis cineraria and date palm form the basis of the rural economy in many countries, and are of great cultural importance; Jojoba and Jatropha have attracted interest as non-conventional sources of industrial oil and biodiesel. This book includes chapters on the seed biology, reproduction, mycorrhizae, stress physiology, and metabolism of desert plants, and describes current biotechnological approaches to their cultivation. It will be useful to researchers, teachers and students in the fields of plant sciences, agriculture, and forestry, and those involved in the management and conservation of desert ecosystems.

Desert Truffles

Desert truffles are found in every known desert, irrespective of the habitat - cool or hot, loamy or acidic, sandy or heavy soil - the only common condition seems to be a limited supply of water. In contrast to 'true' truffles, desert truffles have evolved over time in different families, mainly within the order Pezizales. While in some arid areas, desert truffles have been traditionally used as food, in most regions interest has only recently been increasing, and truffles are now treasured for their nutritional value, as an income source and for research. This volume gives a comprehensive overview of the phylogeny, biology, mycorrhizal association, and distribution of desert truffles, their use, biochemical and medicinal properties, as well as their domestication and cultivation.

Desert Weeds: Personal Narrative on Botanical First Responders

In their rapid colonization of soil exposed by fires, floods, and grazing animals, weeds resemble the human specialists we label Emergency Medical Technicians (EMTs). Weeds are the first responders when disasters occur in nature. They occupy bare soil and prevent erosion by wind and water. In extreme cases such as a landslide, weeds are essential to the healing processes that replace the lost soil. Like a Band-Aid on a skinned knee, weeds protect the land while it recovers. Besides protecting the soil after disaster, weeds provide food for wildlife, and some of them provide food and medicine for people. Able to withstand harsh conditions, weeds will proliferate as global warming and other human impacts intensify. Thus, nature’s EMTs will increase while all other plants decline. The book provides a succinct definition of weeds according to their form and function in ecosystem processes. The narrative uses a representative set of weed species from a desert location to illustrate the full range of weed characteristics.

Desertification: Environmental Degradation In And Around Arid Lands

The United Nations Water Conference (in Argentina in March 1977) and the United Nations Conference to Combat Desertification (in Kenya in August 1977) reflect the worldwide attention that recent global food shortages and growing populations have drawn to the destruction of arable and potentially arable land. This collection of articles focuses on a primary form of such destruction: desertification—the creation of desert-like conditions in arid or semiarid regions either by changes in climate patterns or by human mismanagement, or both. The contributors—representing a range of disciplines—examine and evaluate the social, political, economic, environmental, and technical problems related to the causes and effects of desertification.

Desertification and Land Degradation: Concept to Combating

Desertification and land degradation are complex phenomena, and we need to understand their causes, consequences, and means to mitigate and combat their impact. Therefore, this book aims to explain the concept and characteristics of drylands, desert and desertification, land degradation, wastelands, and the concept of ecosystem services. It also discusses various types of processes of land degradations, their characteristics, physics and indicators along with mapping, monitoring and assessment of methods involved. Concept of Ocean Biological Deserts is discussed along with international and regional efforts towards combating land degradation and desertification. Key Features:• Provides all the aspect of desertification and land degradation at one place • Includes comprehensive methods to monitor different desertification/land degradation processes • Comprehensive overview of the mapping, monitoring and modelling techniques • Role of space borne data in identifying, monitoring and combating desertification is evaluated and reported with real case studies • Explains the concept of ocean biological deserts, their characteristics and mapping
