We show in this paper that the circulant graph G(2 m ; 4) is Hamilton decomposable, and propose a recursive construction method. This is a partial answer to a problem posed by B. Alspach.
Species delimitation within Angraecum section Dolabrifolia is problematic due to morphological variability coupled with overlap in many of the characters traditionally used to distinguish species. Recent molecular phylogenetic studies of the genus included three of the five currently described species of the Dolabrifolia group, placing them as sister to… (More)
Scorodophloeus zenkeri is a tropical tree from mature rainforests of Central Africa, locally threatened by overexploitation. Ten nuclear microsatellite markers, amplifiable in two multiplexed reactions, were developed and characterized in one population. The levels of polymorphism observed (3–15 alleles per locus, expected heterozygosity ranging from 0.198… (More)
