The present paper presents significant changes occurred in the multi-annual dynamics of zooplankton diversity and abundance (1980-2007), under the pressure of human-induced eutrophication in two shallow lakes specific for the Danube Delta. Zooplankton community from lakes Matita and Merhei was characterized by high species richness but low abundance values until 1981, in ecological conditions unaffected by eutrophication. For the next ten years,
Read moreBased on July land surface temperature (LST) in the Romanian Carpathians derived from MODIS (Moderate Resolution Imaging Spectroradiometer) images, this paper investigates the vertical thermal lapse and the influence of several factors. The astronomical parameters, atmospheric circulation and geographical factors are relatively similar in the area of interest, so that the influence of elevation, aspect, and land cover becomes more relevant at regional

In order to resolve it, this paper proposes a methodology based on potential accessibility, determined by the total population served, and the effi ciency of the path, by analogy with the least squares
Read moreStarting from a critical comparative analysis of how the systemic conception is applied in geography, ecology and spatial planning, with a particular focus on the new concept of 'territorial system', the book demonstrates the hypothesis according to which the transfer of statistical methods currently used to study ecological systems toward the analysis of territorial systems is not only possible, but also beneficial based on theoretical foundations
Read moreThe extensive use of the Geographical Information Systems, but also of their extensions, in fields that do not necessary connect to geography, but allow for the implementation of methodologies based on the analysis of spatially referenced data, had resulted into new applications and methodological approaches to answer specific research questions. This paper proposes such an extension from the real space define by longitude and latitude to a virtual
Read moreIn 1999 Romania became part of the Bologna process, focused on the European Credit Transfer and Accumulation System, design to increase the compatibility of European universities, ensuring the mobility of students and professors in the context of re-orienting education to the formation of competences continuously adapted to market requirements. This model draws the new education system closer to American education. The paper analyzes the importance
Read moreClime change represents an important issue for the scientific community regardless of the specific field of study due to the environmental effects and impacts on the economy (especially agriculture) and human communities. The environmental impacts include the loss of biodiversity (species and ecosystems), while agricultural impacts include the exposure to heat, changes of the precipitation regime, and dispersion of diseases and pests. The assessment
Read moreDown’s syndrome represents an important public health issue in the United States (US). The purpose of this analysis was to investigate the relationship between maternal smoking and Down syndrome, among white and black women separately using birth certificate data. After adjusting for alcohol consumption and gestational age, the effect of smoking on Down syndrome appeared to differ among black and white women. There was a reduced risk for Down syndrome
