“…In several tropical tree species, the variation within populations is greater than among populations (Zucchi et al, 2005). The pattern of distribution of the genetic diversity within the population was also observed in three species of the Lauraceae family: Ocotea catharinensis (80%), Ocotea odorifera (88%), and Ocotea porosa (84%) (Martins et al, 2015). Souza and Moscheta (2000) studied the breeding system of N. megapotamica, focusing on the flowering patterns and the synchronization of flowering, and identified the presence of an anti-selfing mechanism.…”

“…The high and very high genetic differentiation observed between clusters 1 and 2, and 2 and 3, respectively, might be due to the relatively lower gene flow between individuals in these groups, as a result of a less synchronous activity of floral organs and pollinators. In O. catharinensis, O. odorifera, and O. porosa, the calculated F ST values were relatively lower (0.148, 0.086, and 0.116, respectively), suggesting an effective gene flow among populations prior to habitat fragmentation (Martins et al, 2015). Zucchi et al (2005) suggested that the variation among populations has direct conservation implications, indicating that a greater number of populations have to be sampled when the F ST is high.…”

“…Mesmo assim, há de se considerar que análises espaciais amplas, baseadas em dados relativamente grosseiros, permitem investigar regiões potencialmente importantes nas quais podem ser realizados estudos mais detalhados, como para avaliar fragmentação de hábitat, padrões de viabilidade populacional, ou manutenção da diversidade genética (Diniz-Filho et al 2009). Estudos como o que avaliou a diversidade genética em populações de três espécies de Ocotea ameaçadas de extinção, apontando quatro populações prioritárias para conservação in situ no Paraná (Martins et al 2014).…”

“…Por fim, o tamanho da população de canela-sassafrás encontrada no estudo, aliado aos resultados aqui apresentados, faz surgir a necessidade de novos estudos, dessa vez enfocando a variabilidade genética que possa existir entre indivíduos e entre outras populações já estudadas no país, como fizeram Martins et al (2015). Os autores estudaram adultos de nove populações geneticamente semelhantes (12% de variação), mas encontraram mu ita variabilidade dentro das populações (88% de variação).…”
