The stone crayfish, Austropotamobius torrentium, is one of the oldest freshwater crayfish species in Europe. Most Carpathian populations are in Romania, with a distribution clustered in 2 compact metapopulations in the western part of the country. Our goal was to understand if this pattern is the result of a coincidence or a complex set of restrictive circumstances. Romania is an ideal place to analyze crayfish distributions because they have not

The increasing availability of high resolution imagery has triggered the need for automated image analysis techniques, with reduced human intervention and reproducible analysis procedures. The knowledge gained in the past might be of use to achieving this goal, if systematically organized into libraries which would guide the image analysis procedure. In this study we aimed at evaluating the variability of digital classifications carried out by three

Based on a case study, this paper aims to be the first attempt, in the Romanian geography, to analyze the snow avalanche potential in one of the most representative glacial areas from the Făgăraş Massif (Southern Carpathians – Romanian Carpathians), respectively Bâlea glacial area, located on the northern slope of the Făgăraş massif, in the central glacial sector. Although this area is subject to a permanent snow avalanche activity and a
