Mauritia flexuosa (aguaje) is a dioecious indigenous species from the family Arecaceae, important for local people and also for the Amazon rainforest as a whole. However, an unsustainable way of fruit collecting leads to the loss of diversity at all levels. The main objective of this research was to assess the intra-population and inter-population genetic diversity of M. flexuosa in the Peruvian and Ecuadorian Amazon by SSR markers. The sampled populations were characterized by high values of genetic diversity and very low levels of inbreeding. They did not reflect the existence of any clear…mehr

Produktbeschreibung
Mauritia flexuosa (aguaje) is a dioecious indigenous species from the family Arecaceae, important for local people and also for the Amazon rainforest as a whole. However, an unsustainable way of fruit collecting leads to the loss of diversity at all levels. The main objective of this research was to assess the intra-population and inter-population genetic diversity of M. flexuosa in the Peruvian and Ecuadorian Amazon by SSR markers. The sampled populations were characterized by high values of genetic diversity and very low levels of inbreeding. They did not reflect the existence of any clear stratification, which can be explained by long-term human activity in the Amazon and its contribution to the higher genetic diversity of M. flexuosa. Also, the gene flow could be affected by rivers. Any interference in the culmination of the rivers could irreversibly break long-lasting linkages and could easily result in an immediate decline in genetic diversity.The study was conducted under the supervision of doc.Ing. Bohdan Lojka, PhD and Ing. Marie Kalousová (Fac. of Tropical AgriSciences-CULS), Universidad Nacional de Ucayali-UNU, Instituto de Investigaciones de la Amazonía Peruana-IIAP.
Autorenporträt
Dita Mervartová estudió en la Universidad Mendel de Brno y, posteriormente, en la Universidad Checa de Ciencias de la Vida de Praga. Desde su licenciatura, le fascina la Amazonia peruana, donde se dedicó a la conversión de la plantación de coca en sistemas agroforestales de cacao y también a la diversidad genética de la Mauritia flexuosa.
