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. Also presented are two sets of case studies, one on animals, the other on plants, which illustrate a variety of approaches, including the application of molecular genetic markers, the investigation of reproductive biology, and the combination of demographic monitoring and modeling, to examine long-term population viability.
Read more- Focuses on habitat fragmentation, one of the most serious threats to species worldwide
- Unique integrated approach - considers both genetic and demographic data to assess population viability in fragmented habitats
- Brings together the relevant theory required to manage conservation in fragmented habitats
- Presents a range of case studies which illustrate a variety of approaches for examining long-term population viability
Reviews & endorsements
'I really enjoyed some of the case studies … understanding deterministic decline and its cure represents the greatest challenges to conservation biology. However, Clarke and Young show that understanding small-population processes might help maintain populations until 'the patient' can be cured.' Ken Norris, Biologist
