Atmospheric arsenic species adsorbed on pollen samples were extracted and determined by liquid chromatography coupled to inductively coupled plasma mass spectrometry (LC-ICP- MS). The optimised extraction method required...

A study was undertaken to ascertain the analytical capabilities of l-methionine immobilized on controlled pore glass for Sb preconcentration and speciation. A fully automated on-line system, implemented with hydride gene...

Speciation through homoploid hybridization (HHS) is considered extremely rare in animals. This is mainly because the establishment of reproductive isolation as a product of hybridization is uncommon. Additionally, many t...

The objective of this study was to describe the morphological and anatomical features of five unidentified ectomycorrhizal types of Alnus acuminata and to complement their identification using ITS-DNA sequence analysis...

In few groups of parasites have the patterns of distribution been studied using quantitative methods, even though, the study of these organisms indirectly provides information on the biogeographic history of their hosts,...

In poorly known groups for which data are insufficient to develop biologically plausible model-based approaches to phylogeographical analyses, a ‘first hypotheses’ protocol is suggested as offering the best way to ge...

In the last decades, the determination of trace elements in biological materials has emerged as an important area of study because of its relevance to human health and the environment. Inductively coupled plasma mass spe...

An on-line inorganic (InHg) and organomercury (OrHg) species separation, preconcentration and determination system consisting of cold vapor atomic absorption spectrometry (CV-AAS) coupled to a flow injection (FI) method ...
