Landscape‐scale deforestation decreases gene flow distance of a keystone tropical palm, Euterpe edulis Mart (Arecaceae)
Habitat loss represents one of the main threats to tropical forests, which have reached extremely high rates of species extinction. Forest loss negatively impacts biodiversity, affecting ecological (e.g., seed dispersal) and genetic (e.g., genetic diversity and structure) processes. Therefore, understanding how deforestation influences genetic resources is strategic for conservation. Our aim wa...
متن کاملconstruction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
Effects of management on the genetic structure of Euterpe edulis Mart. populations based on microsatellites Efeitos do manejo na estrutura genética de populações de Euterpe edulis Mart. com base em marcadores microssatélites
We investigated the effects of two exploitation systems – traditional and management on the levels of variability and genetic structure of Euterpe edulis Mart. populations, by comparing two unlogged populations with two impacted populations in southern Brazil. Three cohorts, from seedlings to adults, were examined using 10 microsatellite loci. The mean values of genetic diversity (Â; He; Ho) we...
متن کاملPhytochemical and nutrient composition of the freeze-dried amazonian palm berry, Euterpe oleraceae mart. (acai).
Euterpe oleraceae is a large palm tree indigenous to the Amazon River and its tributaries and estuaries in South America. Its fruit, known as acai, is of great economic value to native people. In this study, a standardized freeze-dried acai fruit pulp/skin powder was used for all analyses and tests. Among many findings, anthocyanins (ACNs), proanthocyanidins (PACs), and other flavonoids were fo...
متن کاملGenetic structure and mating system of Euterpe edulis Mart. Populations: a comparative analysis using microsatellite and allozyme markers.
A comparative study between microsatellite and allozyme markers was conducted on the genetic structure and mating system in natural populations of Euterpe edulis Mart. Three cohorts, including seedlings, saplings, and adults, were examined in 4 populations using 10 allozyme loci and 10 microsatellite loci. As expected, microsatellite markers had a much higher degree of polymorphism than allozym...
