The massive task of identifying species all over the earth has always been a major challenge in relations to biological monitoring and cataloguing. DNA barcoding is an avant-garde molecular technique, which promises to provide us with a universal key for the taxonomical identification and classification of species via miniature DNA sequences. DNA barcoding utilizes mitochondrial Cytochrome C ox...
Morphology of the first instar larvae of Collembola has considerably taxonomical and phylogenetic significance. We describe the first instar larvae for the first time in Homidia. External morphology of first instar larvae and adults of Homidia jordanai sp. n. is described based on observations under light and scanning electron microscopes. Most organs of adults bear considerably more setae than...
NIR-FT-Raman spectroscopy was applied for a nondestructive analysis of single seeds (fruit mericarps) of 36 accessions belonging to various species of the Apiaceae family. Main seed components such as fatty acids, polysaccharides, proteins, and lignin were identified based on the obtained Raman spectra. Variation at the species and genus level was related to differences observed between spectra...
