Mendelian inheritance, linkage and genotypic disequilibrium in microsatellite loci isolated from Hymenaea courbaril (Leguminosae)
The Neotropical tree Hymenaea courbaril, locally known as Jatobá, is a valuable source of lumber and also produces comestible and medicinal fruit. We characterized Mendelian inheritance, linkage and genotypic disequilibrium at nine microsatellite loci isolated from H. courbaril, in order to determine if they would provide accurate estimates of population genetic parameters of this important Amazon species. The study was made on 250 open-pollinated offspring originated from 14 seed trees.
Molecular differentiation in natural populations of Anopheles oswaldoi sensu lato (Diptera: Culicidae) from the Brazilian Amazon, using sequences of the COI gene from mitochondrial DNA
Anopheles (Nyssorhynchus) oswaldoi (Peryassú, 1922) s. l., which has been incriminated as a potential human malaria vector in Western Brazilian Amazon, may constitute a cryptic species complex. However, the most recent study with isozymes indicated high similarity among samples from the States of Acre, Amazonas and Rondônia in the Brazilian Amazon.
