In this research we used numerical analysis of environmental and morphometric data sets to study the possibility of environmental control of leaf morphology in Betula pendula stands from five regions of Croatia. The correlations were poor between leaf variables and the ecological gradients of the stands, as well as between the ecological, vegetational and biometric characteristics of the two morphologically...
Although intraspecies researches within the black pine (Pinus nigra Arnold) have a long tradition, the intraspecies taxonomy, classification and chorology are still unclear. Among the numerous reasons that have caused this situation the most important are: the absence of a study that would completely cover the whole range of this species, the impossibility of connection of results of the existing...
There are many unsolved taxonomic problems at the intraspecific level in the genus Thalictrum (Ranunculaceae), which may be clarified using molecular systematics methods. No molecular systematics methods have been applied yet to the genus Thalictrum; this study analyzes different leaf tissue preservation and DNA isolation techniques, and the applicability of RAPD. A modified DNA isolation procedure...
