Although consensus has now been reached on a general two-locus DNA barcode for land plants, the selected combination of markers (rbcL + matK) is not applicable for ferns at the moment. Yet especially for ferns, DNA barcoding is potentially of great v

Background and Aims: Populations established by long-distance colonization are expected to show low levels of genetic variation per population, but strong genetic differentiation among populations. Whether isolated populations indeed show this geneti

Shari'a Compliant Finance: The Overlooked Element for Developing an Effective Financial System in Afghanistan

Autor: Jan W Maas

An effective financial system is essential to economic development. US Army doctrine acknowledges that military forces play an important role in supporting economic stabilization and infrastructure development. A specific task is to support the finan

Well-resolved phylogenetic trees are essential for us to understand evolutionary processes at the level of species. The degree of species-level resolution in the plant phylogenetic literature is poor, however, largely due to the dearth of sufficientl

Age and the greenness of leaves have been frequently used as indicators for selecting herbarium specimens for molecular studies. Although plant DNA extraction and amplification have been common lab procedures for the past 20 years, no studies specifi
