Identification of the genetic mechanisms underlying phenotypic variation between and within populations is essential to understanding natural selection and evolution. Changes in gene expression are an important source of phenotypic variation and may arise as a result of a combination of cisregulatory and trans-regulatory variation within complex genetic networks (Wittkopp, 2005). This complexit...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
Parallel evolution is the independent evolution of the same phenotype or genotype in response to the same selection pressure. There are examples of parallel molecular evolution across divergent genetic backgrounds, suggesting that genetic background may not play an important role in determining the outcome of adaptation. Here, we measure the influence of genetic background on phenotypic and mol...
Understanding the genomic basis of adaptation is critical for understanding evolutionary processes and predicting how species will respond to environmental change. Spinner dolphins in eastern tropical Pacific (ETP) present a unique system studying adaptation. Within this large geographical region are four spinner dolphin ecotypes with weak neutral genetic divergence no obvious barriers gene flo...
