Download or read book The Live Bird Trade in Tanzania written by R. K. Tibanyenda and published by IUCN. This book was released on 1996 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The practice of keeping live birds in captivity has been widespread throughout this century and has increased considerably as the 20th century comes to a close. In the last decade or so, the increased trade in live birds from Tanzania has given rise to a number of concerns regarding the sustainability of the trade, its effects on bird numbers, and illegal trafficking. As part of its efforts to palliate the lack of legislation and planning in this domain and to evaluate the effects of this trade, in 1990 the Tanzanian government initiated the Planning and Assessment for Wildlife Management (PAWM) project. As part of this project, a workshop on the live bird trade in Tanzania was organized in Dar Es Salaam in December 1991 and gave rise to a series of initiatives. This publication provides a record of these initiatives and of the PAWN's efforts to arrive at and implement them. It also provides a record of the papers presented during the workshop and the recommendations that emerged therefrom.

Download or read book Munias and Mannikins written by Robin Restall and published by A&C Black. This book was released on 2010-08-30 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers 43 species of munias and mannikins. Munias are widespread throughout the Old World's tropical regions. In their natural habitat, they are birds of the savanna, but they have adapted to a number of different habitats, including areas inhabited by humans. They range in size from the Java sparrow (which is about the size of a common starling) to the diminutive Madagascar mannikin. Their striking plumage makes them popular as cagebirds and they breed readily in captivity. The author has recently described one new species and ten new subspecies to science.
Download or read book Adaptive Genetic Variation in the Wild written by Timothy A. Mousseau and published by Oxford University Press. This book was released on 2000-01-13 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two of the great mysteries of biology yet to be explored concern the distribution and abundance of genetic variation in natural populations and the genetic architecture of complex traits. These are tied together by their relationship to natural selection and evolutionary history, and some of the keys to disclosing these secrets lie in the study of wild organisms in their natural environments. This book, featuring a superb selection of papers from leading authors, summarizes the state of current understanding about the extent of genetic variation within wild populations and the ways to monitor such variation. It proposes the idea that a fundamental objective of evolutionary ecology is necessary to predict organism, population, community, and ecosystem response to environmental change. In fact, the overall theme of the papers centers around the expression of genetic variation and how it is shaped by the action of natural selection in the natural environment. Patterns of adaptation in the past and the genetic basis of traits likely to be under selection in a dynamically changing environment is discussed along with a wide variety of techniques to test for genetic variation and its consequences, ranging from classical demography to the use of molecular markers. This book is perfect for professionals and graduate students in genetics, biology, ecology, conservation biology, and evolution.
Download or read book Adaptive Function and Brain Evolution written by Agustín González and published by Frontiers E-books. This book was released on 2014-10-27 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain of each animal shows specific traits that reflect its phylogenetic history and its particular lifestyle. Therefore, comparing brains is not just a mere intellectual exercise, but it helps understanding how the brain allows adaptive behavioural strategies to face an ever-changing world and how this complex organ has evolved during phylogeny, giving rise to complex mental processes in humans and other animals. These questions attracted scientists since the times of Santiago Ramon y Cajal one of the founders of comparative neurobiology. In the last decade, this discipline has undergone a true revolution due to the analysis of expression patterns of morphogenetic genes in embryos of different animals. The papers of this e-book are good examples of modern comparative neurobiology, which mainly focuses on the following four Grand Questions: a) How are different brains built during ontogeny? b) What is the anatomical organization of mature brains and how can they be compared? c) How do brains work to accomplish their function of ensuring survival and, ultimately, reproductive success? d) How have brains evolved during phylogeny? The title of this e-book, Adaptive Function and Brain Evolution, stresses the importance of comparative studies to understand brain function and, the reverse, of considering brain function to properly understand brain evolution. These issues should be taken into account when using animals in the research of mental function and dysfunction, and are fundamental to understand the origins of the human mind.
