Available in PDF, EPUB and Kindle. Book excerpt: Evolution of Castes in Insects l BERNHARD RENSCH The evolution of organisms in the succession of generations has been primarilly achieved through the appearance of new hereditary variants with minor deviations along with the development of stable structures and functions. Harmful mutants were eradicated either immediately or in the subsequent generations through the process of natural selection while unharmful or advantageous ones usually survived. As this process continued, many new races and species developed which possessed structures and functions of a rational nature and which became increasingly independent from their environment. These evolutionary tendencies were also promoted through either geographical, ecological, physiological or genetical isolation of populations. In some phylogenetic lines, there occurred an increase in the number of cells due to additional cellular divisions in the morphogenesis of structures. This opened up the possibility for the development of the division of labour within cellular groups leading to more complicated and consequently more successful functions of tissues and organs. A further advancement in the adaptation of a species to its environment was made possible through specialization for certain functions of whole individuals or groups of individuals.

Download or read book The Physiology of Insect Reproduction written by Franz Engelmann and published by Elsevier. This book was released on 2013-10-22 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Physiology of Insect Reproduction provides a comprehensive coverage of insect reproductive system. The title details basic phenomena governing reproductive processes in insects, with the whole spectrum of an insect reproductive cycle. The text first covers insect genitalia, and proceeds to discussing sex determination. Next, the selection talks about the development of unfertilized eggs in insects. The text also deals with gonadal development, along with insect mating behavior. Chapter 7 details the factors that affect egg production and fecundity, while Chapter 8 tackles hormonal control of egg maturation. The ninth chapter covers endocrine influence on reproduction in the male insect. The next chapters discuss oviposition, heterogony, and viviparity. The last two chapters deal with functional hermaphroditism and insect societies, respectively. The book will be of great use to students and researchers in the field of entomology.

Download or read book Economics and Ecology of Diversification written by François Ruf and published by Springer. This book was released on 2015-09-23 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The monoculture systems that have been encouraged by governments since the 1960s have led to major socio-economic and environmental crises. Now the diversification of tree crop systems is advancing throughout the tropics. Why and when does diversification take place? What categories of farmers diversify? What obstacles do they have to overcome, and how do public and private policies interfere in this process? How do land use systems and landscapes evolve as a result of this diversification? According to the authors of this volume, diversification is certainly a response to market risks, but also to the depletion of environmental resources. Ecological changes such as declining soil fertility and increasing pressure from pests, diseases and weeds intensify at the end of monoculture cycles, driving crop change and diversification of farming systems. Through 15 case studies from Africa, Latin America, Asia and the Pacific, the authors provide us with in-depth insights into the economy and ecology of family agriculture and its recent developments.

Available in PDF, EPUB and Kindle. Book excerpt: Does the diagnosis of irreversible destruction of both forests and their biodiversity actually mask a wide range of patterns? Based on the results of natural and social scientists, this book attempts to answer fundamental questions such as: what is deforestation and how do we mesure it? What changes result from deforestation and how do human societies manage these changes? It explores the many and varied aspects of deforestation, a process whose effects are not always as negative as perceived.

Download or read book Cocoa Cycles written by François Ruf and published by Woodhead Publishing. This book was released on 1995-06-30 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cyclical boom-to-recession nature of the economics of cocoa supply is a major problem for the international cocoa industry - and especially for countries whose economies depend on cocoa exports. Only through an understanding of the dynamics of cocoa cycles can policy decisions be made through the various phases of supply cycles. Based on a major international cocoa conference, this book presents seventeen edited papers from leading experts, making a major contribution to that understanding. It explains the powerful economic, social and political factors which impact on the cocoa economy. It shows the laws of cocoa supply are closely linked to environmental, ecological and institutional factors.

Download or read book Early Days in Complex Dynamics written by Daniel S. Alexander and published by American Mathematical Soc.. This book was released on 2012 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theory of complex dynamics, whose roots lie in 19th-century studies of the iteration of complex function conducted by Koenigs, Schoder, and others, flourished remarkably during the first half of the 20th century, when many of the central ideas and techniques of the subject developed. This book paints a robust picture of the field of complex dynamics between 1906 and 1942 through detailed discussions of the work of Fatou, Julia, Siegel, and several others.
