The combination of nitrogen and carbon isotope ratios with fatty acids (FA) analysis is a useful tool for food web studies in cryptic belowground systems. The study investigates trophic niche diferentiation of Collembola communities from the litter of two Romanian beech forests and determines the origin of posible food sources consumed by springtails using fatty acid technique. δ15N signatures of Collembola taxa in the investigated food web spanned

The paper reports a feeding experiment showing that Heteromurus nitidus, a widespread and common springtail species found in a variety of habitats rich in organic matter, was capable of feeding upon nematodes in the laboratory. DNA/PCR based molecular gut analysis of Heteromurus nitidus for two nematode species, namely Phasmarhabditis hermaphodita and Steinernema feltiae, and one soil alga, Chlorococcum infusionum, was done in the laboratory using

The description of two new species of the genus Deuteraphorura Absolon, 1901 from Doftana Valley, Romania is given. Deuteraphorura dianae sp. nov. has the pseudocellar formula dorsally: 32/033/33353 and ventrally: 3/011/3112. Deuteraphorura doftana sp. nov. is characterized by its dorsal (33/033/33354) and ventral 3/011/3212) pseudocellar formulae. A proposed key to the all species of Deuteraphorura from the world without pseudocelli on the thoracic

A new species of the Tetracanthella pilosa group is described from Romanian Carpathians. T. doftana sp. nov. is similar to T. andalusiaca Deharveng, 1987. They differ by the number of sublobal hairs, size of macrochaetae and distribution. A key to Carpathian Tetracanthella Schött, 1891 species is also given.
