Available in PDF, EPUB and Kindle. Book excerpt: This book will give an overview of insect ovaries, showing the diversities and the common traits in egg growth processes. The idea to write this book developed while looking at the flood of information which appeared in the early 1980s on early pattern formation in Drosophila embryos. At this time a significant breakthrough was made in studies of this little fly, combining molecular biological methods with classical and molecular genetics. The answers to questions about early pattern formation raised new questions about the architecture of ovaries and the growth of eggs within these ovaries. However, by concentrating only on Drosophila it is not possible to form an adequate picture of what is going on in insect ovaries, since the enormous diversity found among insects is not considered sufficiently. Almost forgotten, but the first to study the architecture of ovaries, was Alexander Brandt writing in 1878 in aber das Ei und seine Bildungsstaette (On the egg and its organ of development). More than 100 years later, a series of ten books or more would be required to survey all the serious informa tion we have today on insect oogenesis. Thus, this book is a personal selection and personal view on the theme, and the authors must be excused by all those scientists whose papers could not be included. The book briefly describes the ectodemes, i. e.

Download or read book Human-Animal Interactions in Zoos written by Eduardo J. Fernandez and published by CABI. This book was released on 2024-05-30 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past couple of decades, Animal-Visitor Interactions (AVI), a type of Human-Animal Interaction (HAI), have become one of the major topics of interest for researchers working in zoos, especially in relation to animal welfare. This thought-provoking book summarizes the latest research concerning the impacts on HAIs in zoos, including the effects of visitors on animals and the effects of animals, exhibits, and the place itself on visitors. An invaluable resource for ethologists and animal behaviour and welfare students and practitioners, as well as social scientists and indeed anyone working with zoo animals.

Download or read book Handbook of Animal Diversity written by Richard E. Blackwelder and published by CRC Press. This book was released on 2019-08-08 with total page 789 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a summary of the diversity between and within the classes of animals. It is intended for reference on all aspects of animals that can be studied comparatively, but such comparisons requires that the occurrence of the feature in question beknown for more than just one or two groups. It is in large part a book on invertebrate animals because the vertebrates from only a small part of the diversity of animals.

Download or read book The Mayflies of Europe (Ephemeroptera) written by Ernst Bauernfeind and published by BRILL. This book was released on 2013-01-21 with total page 779 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the various groups of aquatic insects, mayflies (Ephemeroptera) are of special interest for professional limnologists and entomological researchers as well as for naturalists in general and even the dedicated fly angler. Identification has traditionally been considered difficult and implementation in environmental monitoring and freshwater management has led to an ever increasing demand for exact information on taxonomy and ecology. The present handbook is designed to provide for the first time an up-to-date standard work for Ephemeroptera identification, including last instar larvae (nymphs), subimago (dun), male and female imagines. Recent changes in nomenclature are discussed in detail as well as gaps in current knowledge and probable pitfalls concerning the reliable identification of all taxa known so far from the region. Keys are provided for genera and introductory chapters characterize every family and genus. Species accounts follow a common format providing a synonymy, characters for identification (including literature references), remarks (on type material, variation, confusing or extralimital species) and short information on biology and distribution pattern. Male genitalia are illustrated by micrographs and line drawings, REM photographs of the egg chorionic structure are provided for genera and selected species. Habitus of larvae and imagines are for most genera illustrated by colour photographs. The geographical area covered is Europe including the European part of Russia, the mediterranean islands and North Africa. Short additional information is provided for adjacent parts of the western Palaearctic Region. A comprehensive index, check-list and distribution catalogue (following the widely adopted concept of Illies’ Limnofauna Europaean) allow for quick information on all species recorded so far from Europe.
