Book Summary:

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 isolating them yet further and dooming many to eventual extinction! Many small population fragments are going extinct principally for genetic reasons. Although the rapidly advancing field of molecular genetics is continually providing new tools to measure the extent of population fragmentation and its genetic consequences, adequate guidance on how to use these data for effective conservation is still lacking. This accessible, authoritative text is aimed at senior undergraduate and graduate students interested in conservation biology, conservation genetics, and wildlife management. It will also be of particular relevance to conservation practitioners and natural resource managers, as well as a broader academic audience of conservation biologists and evolutionary ecologists.

Book Summary:

"The biological diversity of the planet is being rapidly depleted due to the direct and indirect consequences of human activity. As the size of wild animal and plant populations decreases and fragmentation increases, inbreeding reduces fitness and loss of genetic diversity reduces their ability to adapt to changes in the environment. Many small isolated populations are going extinct unnecessarily. In many cases, such populations can be genetically rescued by gene flow from another population within the species, but this is very rarely done. This book provides a practical guide to the genetic management of fragmented animal and plant populations"--

Book Summary:

One of the greatest unmet issues in conservation biology is the genetic management of fragmented populations of numerous animal and plant species. Many populations are going extinct unnecessarily for genetic reasons so there is now urgent need for an authoritative textbook on the rational genetic management of fragmented populations.

Book Summary:

Habitat fragmentation is one of the most ubiquitous and serious environmental threats confronting the long-term survival of plant and animal species worldwide. As species become restricted to remnant habitats, effective management for long-term conservation requires a quantitative understanding of the genetic and demographic effects of habitat fragmentation, and the implications for population viability. This book provides a detailed introduction to the genetic and demographic issues relevant to the conservation of fragmented populations such as demographic stochasticity, genetic erosion, inbreeding, metapopulation biology, and population viability analysis. The volume presents case studies on animals and plants, which illustrate a variety of approaches to examining long-term population viability. Some of the approaches include the application of molecular genetic markers, the investigation of reproductive biology, and the combination of demographic monitoring and modeling.

Book Summary:

The 2nd Interface Between Ecology and Land Development Conference was held in association with Earth Day 1997, five years after the first Interface Conference. Rapid population growth in California has intensified the inevitable conflict between land development and preservation of natural ecosystems. Sustainable development requires wise use of diminishing natural resources and, where possible, restoration of damaged landscapes. These Earth Week Celebrations brought together resource managers, scientists, politicians, environmental consultants, and concerned citizens in an effort to improve the communication necessary to maintain our natural biodiversity, ecosystem processes and general quality of life. As discussed by our keynote speaker, Michael Soulé, the best predictor of habitat loss is population growth and nowhere is this better illustrated than in California. As urban perimeters expand, the interface between wildlands and urban areas increases. Few problems are more vexing than how to manage the fire prone ecosystems indigenous to California at this urban interface. Today resource managers face increasing challenges of dealing with this problem and the lead-off section of the proceedings considers both the theoretical basis for making decisions related to prescribed burning and the practical application. Habitat fragmentation is an inevitable consequence of development patterns with significant impacts on animal and plant populations. Managers must be increasingly resourceful in dealing with problems of fragmentation and the often inevitable consequences, including susceptibility to invasive oganisms. One approach to dealing with fragmentation problems is through careful landplanning. California is the national leader in the integration of conservation and economics. On Earth Day 1991, Governor Pete Wilson presented an environmental agenda that promised to create between land owners and environmentalists, agreements that would guarantee the protection of -endangered species and out of this grew the pioneering initiative, known as the Natural Communities Conservation Planning (NCCP) program. California's vast expanse of seemingly endless resources has traditionally been viewed as justification for abusive land use practices. The modem day recognition that resources are finite has led to greater concern, not only for conserving what is left, but for restoring abused landscapes. Ecological restoration is a new science devoted to returning disturbed environments to a semblance of their "pristine" state. Based on principles of "revegetation," restoration goes far beyond simple replanting, rather the ambition of ecological restoration is to return landscapes to functioning ecosystems and is the focus of the last section.

Book Summary:

The ongoing anthropogenic impact on our landscape, e.g. by intensification of agricultural use and abandonment of extensively used farmland, strongly affects the persistence of many plant and animal species and populations. Many formerly connected habitats were destroyed or became fragmented. As a consequence many populations became extinct and remnant populations became smaller in size and more isolated. These small and isolated populations are at a higher risk of extinction because they are more sensitive to demographic, environmental and genetic stochasticity. Genetic stochasticity, i.e. genetic drift, and inbreeding in small and isolated populations might lead to reduced individual fitness in the short term. In the long term the ability to react to changing environmental conditions might decrease. Moreover, the environmental conditions in remnant habitats might be of lower quality, e.g. due to increasing edge effects. As species become restricted to remnant habitats, effective management for long-term conservation requires a quantitative understanding of the effects of habitat fragmentation on population viability. Most recent studies of the effects of habitat fragmentation were carried out at relatively small geographical scales. In this thesis I present four studies of the effects of habitat fragmentation on plant performance that investigate offspring performance, quantitative genetic variation and local adaptation in populations at a large geographical scale. Populations were studied in several European regions (in Sweden, The Netherlands, Germany, Britain, Czech Republic, Luxembourg and Switzerland). The target species Carlina vulgaris L. and Hypochoeris radicata L. have contrasting life histories with respect to dispersal ability and the frequency of flowering, but both species are widespread in species-rich semi-natural grasslands throughout Europe. Species-rich grasslands have dramatically declined in number and size in the last decades and are thus an e.
