Status Quo and Orchid Conservation Challenges in the Neotropical Region

  • Chapter
  • First Online:
Conservation Genetics in the Neotropics

Abstract

The varied patterns of genetic differentiation of vulnerable orchids populations (eg. Cattleya genus) urgently need to be known. Here, we present contextualized examples of genetic studies and discuss conservation challenges for orchids in the neotropical region, as the genetic diversity is essential for conservation and management actions of threatened species. In most of the sampled populations of Cattleya granulosa, an endangered orchid inhabiting the Atlantic Forest remnants, for example, there is a body of evidence of the occurrence of genetic bottlenecks. Our study showed that conservation genetics should consider the spatial distribution of genetic diversity in order to develop appropriate conservation strategies. Thus, further advances in the protection of genetic diversity are needed, since conventional databases and public policies may be insufficient in land use planning aiming at biodiversity conservation. In addition to the need to maintain genetic diversity, it is necessary to understand the reproductive and demographic characteristics caused by the interaction of a number of evolutionary and ecological mechanisms to maintain the evolutionary potential of an orchid species or population.
