Genetic Management of Fragmented Animal and Plant Populations
One of the greatest unmet challenges in conservation biology is the genetic management of fragmented populations of threatened animal and plant species. More than a million small, isolated, population fragments of threatened species are likely suffering inbreeding depression and loss of evolutionary potential, resulting in elevated extinction risks. Although these effects can often be reversed by re-establishing gene flow between population fragments, managers very rarely do this. On the contrary, genetic methods are used mainly to document genetic differentiation among populations, with most studies concluding that genetically differentiated populations should be managed separately, thereby...
A Practical Guide for Genetic Management of Fragmented Animal and Plant Populations
The habitats of most species have been fragmented by human actions, isolating small populations that consequently develop genetic problems. Millions of small, isolated, fragmented populations are likely suffering from inbreeding depression and loss of genetic diversity, greatly increasing their risk of extinction. Crossing between populations is required to reverse these effects, but managers rarely do so. A key reason for such inaction is that managers are often advised to manage populations in isolation whenever molecular genetic methods indicate genetic differences among them. Following this advice will often doom small populations to extinction when the habitat fragmentation and genetic differences were caused by human activities. A paradigm shift is required whereby evidence of genetic differentiation among populations is a trigger to ask whether any populations are suffering genetic problems, and if so, whether they can be rescued by augmenting gene flow. Consequently, there is now an urgent need for an authoritative practical guide to facilitate this paradigm shift in genetic management of fragmented populations.
Conservation Biology
This edited volume will provide a treatment of evolutionary conservation biology that introduces and explains major concepts and also unifies recent theoretical and empirical advances.
Problematic Wildlife II
In a world where habitats are constantly changing and the impact of anthropization on the environment is increasingly intense, interactions between human and wildlife are becoming more and more complex. Some species pose problems for human activities while many others need to be helped in order to continue to exist. This book follows the first volume called 'Problematic Wildlife', edited by F.M. Angelici and published by Springer in 2016, which has had considerable success with readers and critics. The volume includes 21 chapters divided into 7 parts devoted specific topics which are approached in a multidisciplinary way. There are both review chapters and specific cases, always bearing in mind the interest for an international audience. The book is useful both for scientists, wildlife specialists, conservationists, zoologists, ecologists, university students, nature managers, and for those who live in contact with wildlife and its problems, such as farmers, shepherds, hunters, urban planners, and staff of parks and nature reserves. Its ultimate goal is to offer scientific and pragmatic approaches to manage each categories of problematic species.

Wildlife Ecology: Conservation And Management
For the present purpose, we may state that "wildlife management" means "the management of animal populations within the framework of the environment." Some would find it too narrow, arguing that wildlife management should also include education, outreach, park management, law enforcement, economics and land appraisal since so many management issues are rooted in interactions between humans and animals. Many of the most pressing questions in wildlife ecology may be reduced to numbers, such as the rate of population increase, the extent of dispersion, or the effects of interactions with other species and the surrounding environment. A conceptual grasp of quantitative ecology is necessary for dealing with these issues. Because we can't always depend on experience to determine the most suitable options, mathematical models are also a vital part of decision-making in wildlife conservation and management. The book also demonstrates that a comprehensive approach is necessary to deal with environmental problems, as opposed to a piecemeal, single-pollutant, or single-medium approach.
Wildlife Ecology: Management And Conservation
The word "wildlife" is used to describe the wide variety of plant and animal species found in the biosphere. Wildlife often relates to vertebrate animals including higher plants, although the phrase may be used to include all forms of biodiversity in the natural world. Wildlife ecology is now a well-established scientific discipline that examines ecosystems on several levels, from genes to biomes. Methods covered in the book include taking an inventory of a population's health and size, studying migration patterns and physiology, assessing habitat quality, and constructing food webs. Wildlife management is difficult because it involves both cutting-edge ecological research and a well-grounde...
