GIS assessment of development gaps among Romanian administrative units
A new set of indices for monitoring the effects of implementing new regional development policies of the European Union, as well as other sectoral policies with territorial effects, resulted into the creation of new flexible systems, able to increase the administrative capacity to access structural and cohesion funds. The novelty of this study consists of the original methodology embedding mathematical methods (i.e., the ELECTRE and the index of
Read moreDiversity of arthropod communities as an indicator of changes produced by the utilization of silvicultural techniques
The dynamics of forest arthropod communities can be completely understood only when based on their trophic connections. Given their importance in detritic food chains with their influence on the rate of decomposing organic matter and the dynamics of nutrients, terrestrial arthropods from litter and soil are useful in monitoring changes in environmental conditions in forest ecosystems. Due to their flexible diet they cannot be appropriately assigned
Read moreGeographical Information Systems Assessment of Development Disparities Among Romanian Regions of Development
New strategies of the European Union, focused directly on regional development or originated from different areas, but leading to changes in this field, had resulted into a set of indices used to monitor the effects of their implementation. Previous studies suggest that flexible systems perform better and could strengthen the administrative capacity of accessing structural and cohesion funds. Our study used the Geographical Information Systems (GIS)
Read moreApplications of Principal Component Analysis integrated with GIS
Principal Component Analysis is a statistical instrument able to identify the variables explaining most variation within a sample. When the lines are administrative units within a region, and the input variable account for a specific issue (e.g., level of development etc.), Principal Component Analysis can be used to pinpoint the variables explaining mostly the specific issue. Moreover, if used in conjunction with GIS modeling, the entire approach
Read moreDynamics of the environmental transformation processes during 1990-2006 in Romania reflected by land cover and use changes
The relationship between the natural and anthropic components of territorial systems or complexes of coupled socio-economic and natural systems is changing in time under the effect of socio-economic and political drivers. One way of looking at it is through the changes of land cover and use, which are connected also to the dynamics of the eco-energies during the anthropization process. The aim of this paper is to perform an analysis of long-term
Read moreLand cover and land use analysis of urban growth in Romania
While cities appeared and disappeared during the history, and different disciplines, such as ecology and geography attempted to model the process from a systemic perspective, the growth of modern cities, particularly under the form of urban sprawl, is an important phenomenon due to its environmental and socioeconomic impacts. CORINE data allow for analyzing the growth of cities based on the changes in land cover and use. This study aimed to assess
Read moreUsing Geostatistical Tools to Pinpoint ‘Hotspots’ Showing Biodiversity Threats: Romania as a Case Study
A relatively new concept, 'global change', refined over the last decade to account for the energy - land use - climate change nexus, describes all changes induced by the human species and its activities affecting natural ecosystems and their biodiversity. This chapter reviews several research projects carried out within the national boundaries of Romania, all attempting to pinpoint, explain and predict the impact of 'hotspots' showing potential threats
Read moreTisza river case study
The river Tisza has the largest catchment area among the tributaries of the river Danube. It covers nearly 160 000 km2 and has about 14 million inhabitants. Extreme weather phenomena are already a serious problem in the region. According to the forecasts, the frequency of extreme weather events in the context of droughts and excess water flooding is expected to increase as a result of climate change. In the course of the vulnerability assessment
Read moreChanging Microspatial Patterns of Sulfate-Reducing Microorganisms (SRM) during Cycling of Marine Stromatolite Mats
Microspatial arrangements of sulfate-reducing microorganisms (SRM) in surface microbial mats (~1.5 mm) forming open marine stromatolites were investigated. Previous research revealed three different mat types associated with these stromatolites, each with a unique petrographic signature. Here we focused on comparing "non-lithifying" (Type-1) and "lithifying" (Type-2) mats. Our results revealed three major trends: (1) Molecular typing using the dsrA
Read moreGIS analysis of wetland cover by NATURA 2000 sites
Geographical Information Systems (GIS) can be used in biological conservation as decision support systems, integrating the spatially referenced CORINE land cover and using data to assess whether natural protected areas cover particular types of ecosystems and/or biogeographical diversity. This study analyzes whether the Natura 2000 sites, which are Special Protection Areas and Special Areas of Conservation declared in Romania cover the diversity
