The Elderly Are Those Who Have Been Lucky Enough To Reach Old Age
Reflections such as these are subtly collected in this book and placed in the light of her own reflections by Luz María Londoño. With secret, fascinated delight, she has journeyed through the vast garden of universal literature, selecting the most memorable thoughts on life and death and that forcible interval called old age, which have thrived from Seneca to the present day. Those of us who have reached the threshold of seventy or eighty years of age cannot remain indifferent to all the memories stirred by these pages. “We all want to live to old age and we all deny that we have done so”, wrote Quevedo. And, centuries later, Trotsky echoed these words in a similar reflection: “To age is the most unexpected of all the things that happen to man”. Very true. Old age is similar to twilight: it suddenly, briefly and intensely lights up the high points of our lives like an announcement and a preamble to night.
E-Infrastructures for Data Publishing in Biodiversity Science
This collection of articles, developed in association with the EU funded ViBRANT project, illustrates how advances to research infrastructures are reciprocally changing the practice of taxonomy. A detailed review of data issues in the life sciences (Thessen and Patterson 2011) sets the tone for subsequent articles in this special issue, whose contributions broadly fall into three categories. Theÿ initial articles consider some of the major infrastructure platforms that support the production and management of biodiversity data. These include the EDIT Platform for Cybertaxonomy, Wiki-based approaches including BioWikiFarm and the Scratchpads Virtual Research Environment. Later articles provi...

Herpetology
Herpetology has always been one of the most exciting disciplines of zoology. During the past few years the field has continued to grow, yet it has been plagued by scarcity of comprehensive, up-to-date textbooks containing the most important developments. This timely book fills that void. Through skillful synthesis, the author summarizes the diversity in the biology of living amphibians and reptiles and describes the breadth of current herpetological research. Topics covered include the evolution, classification, development, reproduction, population, and environmental issues surrounding the study of amphibians and reptiles. Designed as an advanced undergraduate textbook, Herpetology is a valuable resource for students, practitioners, and interested amateurs alike. Provides an incisive survey and much needed update of the field Emphasizes the biological diversity among amphibians and reptiles Details the most recent research findings, citing ke

Primitive Ghost Moths
Hepialidae (ghost moths or swifts) are, in terms of diversity and distribution, the most successful group of homoneurous primitive moths. The morphology of Fraus is described in some detail with emphasis on the adult moth, and a new interpretation of hepialid male genitalia is presented. Beyond describing and illustrating a primitive hepialid, these observations are intended to serve as reference for the study of the classification of Hepialoidea and lower Lepidoptera.In the taxonomic revision, based on more than 3000 specimens, the 25 Fraus species are described and diagnosed. The adult moths, as well as male and female genitalia, are richly illustrated, and distribution maps and flight period diagrams are provided for all species. The biology, behaviour, distribution and phylogeny are summarised and discussed.
Biological Control by Augmentation of Natural Enemies
The protection of agricultural crops, forest, and man and his domestic animals from annoyance and damage by various kinds of pests remains a chronic problem. As we endeavor to improve pro duction processes and to develop more effective and acceptable tactics for achieving this protection, we must give high priority to all potentially useful techniques for the control and management of insects. Pest control is recognized as an acceptable and necessary part of modern agriculture. Methods employed vary greatly and tend to reflect compromises involving 3 determining factors: technological capability, economic feasibility, and social acceptability. How ever, these factors are also subject to chan...
