Genetic erosion is the loss of genetic diversity within a species.
It can happen very quickly, due to catastrophic events, or changes
in land use leading to habitat loss. But it can also occur more
gradually and remain unnoticed for a long time. One of the main
causes of genetic erosion is the replacement of local varieties by
modern varieties. Other causes include environmental degradation,
urbanization, and land clearing through deforestation and brush
fires. In order to conserve biodiversity in plants, it is important
to targets three independent levels that include ecosystems,
species and genes. Genetic diversity is important to a species’
fitness, long-term viability, and ability to adapt to changing
environmental conditions. Chapters in this book are written by
leading geneticists, molecular biologists and other specialists on
relevant topics on genetic erosion and conservation genetic
diversity in plants. This divisible set of two volumes deals with a
broad spectrum of topics on genetic erosion, and approaches to
biodiversity conservation in crop plants and trees. Volume 1 deals
with indicators and prevention of genetic erosion, while volume 2
covers genetic diversity and erosion in a number of plants species.
These two volumes will also be useful to botanists,
biotechnologists, environmentalists, policy makers,
conservationists, and NGOs working to manage genetic erosion and
biodiversity.
