“…Habitat fragmentation and spatial isolation increase populations' genetic drift and differentiation among them, as well as reduce their future adaptation to environmental changes (SANO et al, 2010). Therefore, knowledge of genetic diversity and structure among E. dysenterica populations is required for the development of appropriate conservation and breeding programs.According to a recent finding(VILELA et al, 2013), the structure of E. dysenterica populations based on oil chemical variability agrees with the pattern of genetic variability among populations, based on morphological descriptors(TELLES et al, 2003), isozymes(TRINDADE;CHAVES, 2005), and genetic markers(BARBOSA et al., 2015). On the other hand, there is a clear environmental influence on phenotypic differentiation, given the morphological and chemical characteristics of regions where these populations are found (DUARTE et al, 2012; TRINDADE; CHAVES, 2005).…”
