To investigate the evolution and biogeography of an endemic group of South American foxes, we examined mitochondrial DNA control region sequences for 118 individuals belonging to all six extant species of the genus Lycalopex. Phylogenetic and molecular dating analyses supported the inference that this genus has undergone a very recent and rapid radiation,(More)
We discuss and develop an entropy-driven principle for separating isomers of alkanes in the five to seven carbon atom range by adsorption on silicalite-1. The normal alkanes are preferentially adsorbed because of configurational entropy effects; they “pack” more efficiently within the channel structures of silicalite. To demonstrate the separation principle(More)
