I. Bostan, Al. I. Cuza University, Faculty of Economics and Business Administration, Iasi, Romania. This paper is a synthetic analysis of the Romanian approach of an important underground resource, namely copper ore deposits. Certain elements of the international context have been introduced, highlighting the appreciation of the price of copper, as a result of increased demand from countries wi...

We have described the morphological variation of five Western Palaearctic species of Monochamus Dejean, 1821. The variation was assessed using wing measurements. Special emphasis was placed on the differences between Monochamus sartor (F., 1787) and Monochamus urussovii (Fischer-Waldheim, 1805). There was an interesting pattern of variation between the two species. Individuals of M. sartor from...

We analysed genetic variation of the small Scots pine population from forested area Northern Kiskunság in comparison with other populations Carpathians and Pannonian Basin that we studied earlier by microsatellite markers (SSR). Our results showed indices based on five nuclear SSRs are similar to values detected Hungarian populations. Based STRUCTURE analysis, as well PCoA fits into Western Car...

BACKGROUND AND AIMS Pilosella officinarum (syn. Hieracium pilosella) is a highly structured species with respect to the ploidy level, with obvious cytogeographic trends. Previous non-collated data indicated a possible differentiation in the frequency of particular ploidy levels in the Czech Republic and Slovakia. Therefore, detailed sampling and ploidy level analyses were assessed to reveal a b...

The genital anatomy of Orcula jetschini (Romania), Orcula zilchi (Bulgaria), and Orcula wagneri (Albania) is described. Based on anatomical features (morphology of the penial caecum) shell characters (sculpture and shape) and unpublished molecular data the genus Orcula is subdivided into three subgenera. Orcula zilchi was classified within the monotypic subgenus Orcula (Hausdorfia) subgen. n.; ...

Understanding the potential of forest ecosystems as global carbon sinks requires a thorough knowledge of forest carbon dynamics, including both sequestration and fluxes among multiple pools. The accurate quantification of biomass is important to better understand forest productivity and carbon cycling dynamics. Stand-based inventories (SBIs) are widely used for quantifying forest characteristic...
