- Abstract
Afforestation is a remedial strategy that follows the pattern of natural forest ecosystems, which still are one of the most damaged ecological structures over time. The effectiveness of afforestations at local / regional scale and time scale at which successional phenomena can be observed in these ecological structures and how similar become in time to the structure and functions of natural forest ecosystems, still are of high interest for the scientists and not only. We have chosen for a preliminary study, ten forest plantations situated in the Criş and Mureş river basins (West Romania) grouped into two categories: four-year-old plantations and ten-year-old plantations. Was studied epigeic invertebrate fauna collected both qualitatively and quantitatively. It was followed the taxonomic composition of invertebrate communities, there were calculated the major structural indices of the zoocoenoses and linear correlation coefficient (r) for groups of predators and their potential food. The degree of taxonomic similarity was calculated using the Sørensen index of similarity and it was established the significance level between the existent differences using the Mann-Whitney test. There were noticed significant and highly significant differences between the plantations both in the same age group and of different ages. There are also differences in the way the predators consume the food and also, the strength of the trophic connections between predators and prey.
