Genetic diversity of Cypripedium calceolus in Poland. 52-65, 2014.) this could have a direct impact on long-term survival ( Brzosko et al., 2011 BRZOSKO, E. Genetic effects of forest management practices: global synthesis and perspectives. Individuals with high levels of genetic diversity should be prioritized in sustainable management ( Ratnam, 2014 RATNAM, W. Spatial genetic structure, genetic diversity and pollen dispersal in a harvested population of Astrocaryum aculeatum in the Brazilian Amazon. For the management of forest species, it is important to understand the genetic diversity involved in their populations ( Ramos et al.

Bridging the gap: a genetic assessment framework for population-level threatened plant conservation prioritization and decision-making. However, this information is often ignored in the preparation of management plans, even though it may contribute to their sustainability ( Ottewell et al., 2016 OTTEWELL, K. Genetic diversity and population structure of Chinese jujube (Ziziphus jujuba Mill.) and sour jujube (Ziziphus acidojujuba Mill.) using inter-simple sequence repeat (ISSR) Markers. The information generated by dominant and codominant molecular markers can be used to study genetic diversity, providing relevant information for the management of forest species ( Li et al., 2018 LI, S. prismatica genetic diversity however, considering the economic potential of the species and to minimize impacts on the existing fragments, there is a need to work with the local population to ensure sustainable forest management of the species.Īraucaria forest Conservation Forest management ISSR Therefore, the Faxinal System contributes to the conservation of C. Thus, the populations in the Faxinal System had higher rates of genetic diversity, despite constant human activity within the system. With the analysis of the genetic structure of the populations, which indicated the existence of two distinct genetic groups (K = 2). According to Nei’s genetic identity, the populations form two groups. The Shannon (I) and Nei’s (He) diversity indices were 0.53 and 0.36, respectively. The results show that the average diversity within populations is 80.54%.

Initially, 30 ISSR markers were selected, but only eight showed considerable variability, resulting in 68 polymorphic loci. As such, 120 adult reproductive individuals were sampled, 60 in two areas managed in the Faxinal System, and 60 in two conservation areas. For this reason, this study aimed to select molecular markers and assess whether the Faxinal System contributes to the maintenance of the genetic diversity of the species, helping in its management and conservation. This species also has several uses and potentials, such as wood for fence posts and essential oils with pharmacological properties. Endemic to the Mixed Ombrophilous Forest of south Brazil, is predominant in Faxinal System, which is a traditional agricultural system in the State of Paraná. Curitiba prismatica (D.Legrand) Salywon & Landrum belongs to the Myrtaceae family and it is popularly known as murta.
