Glavacioc River crosses many rural areas in southern Romania. The soil and groundwater in the neighboring area of the Glavacioc River are mainly polluted by nitrates from agriculture (excessive fertilization with mineral nitrogen fertilizers), husbandry (mismanagement of manure) and/or human waste. Based on previous research regarding soil and wate...

The main objective of the study was to analyse, for the first time in Romania, the relationships between five experimental grasslands and Mesostigmata fauna, considering: (1) the structural differences between mite communities; (2) the variations in some important abiotic factors (vegetation cover, soil temperature, soil moisture content, pH, soil...

The research objective was to demonstrate the use of soil fauna groups as a tool for monitoring of the "Springs Complex of Corbii Ciungi" protected area (the IUCN category 4), Dâmboviţa County, Romania.

In the autumn 2017 we have launched “The structure of a transdisciplinary research consortium for bio-geo-interactions research and integrated river basin management” (Lăcătușu et al. 2017). We have targeted in partnerships since 2007 the trans-disciplinary topic of river basin management under the pressure of pollutants and climate changes at diff...

The aim of the present study was to establish the effect of management type and of environmental variables on the structure, abundance and species richness of soil mites (Acari: Mesostigmata) in twelve urban green areas in Bucharest-Romania. Three categories of ecosystem based upon management type were investigated: protected area, managed (metropo...

Despite the growing list of elements assessed and recognised as environmental and human health hazards, pollution monitoring and mitigation strategies are mandatory only for a limited number of metals, for which ambient air quality limits are defined by national and international policies. In order to overcome this deficiency, and promote cost-effe...

The Făgăraș Massif is situated in the central area of the Carpathian Mountains, aligned west to east and whose slopes mainly have north and south aspects. The habitat diversity is high, comprising grasslands from the foot of the mountains to their summits. These grasslands have been used for sheep grazing for centuries. Our study examined six priva...

Following their death, plants and animals decompose into organic substances that reach the soil in different proportion. The relationships between plants and animals are complex, soil invertebrates playing an important role in soil fertility, nutrient turnover and other processes at the soil level. The decomposing organic matter in the soil provide...

Vineyard inter-rows are important biodiversity hotspots within agricultural landscapes, especially when they are covered with vegetation. However, little is known on the effects to management intensity on a broad range of surface-dwelling invertebrates and their interaction with vegetation. We assessed the diversity and activity density of ants, be...

An anthropic ecosystem from Romania was investigated from acarological, vegetation and chemical point of view. The community structures of two groups of mites were studied (Acari: Mesostigmata, Oribatida) from a tailing pond, using transect method, in correlation with concentrations of heavy metals (As, Cu, Pb, Ni, Mn and Zn), with abiotic factors...

During 2014 and 2015, the species Morimus asper funereus Mulsant, 1862 was monitorised in the Măcin Mountains National Park, Romania using the visual transect method.

In 2007, Romania joined to the European Community. In the field of the nature protection, national legislation had to correlate with a European one (especially with Council Directive 92/43/EEC on 21 May 1992 on the conservation of natural habitats and of wild fauna and flora). In order to accomplish this task, the Romanian Government, approved the...

In total, 15 natural forest ecosystems were analyzed (3 deciduous forests, 5 beech forests, 1 fir forest, 5 spruce forests, and 1 mixed forest), from 8 counties in Romania. A total of 240 soil s...

This paper presents the effect of heavy metal soil pollutants (Pb, Cd, Cu, Zn) on soil mite communities in three urban parks within Bucharest, Romania: Cişmigiu, Unirea and Izvor. For each park, the investigations were based on three transects that were established in relation to the nearest source of air pollution i.e. heavy traffic from the main...

Biomonitoring, i.e. using plant species for measuring pollution levels, has been previously explored in several locations using various protocols and organisms in the search for effective strategies and practices for monitoring and reducing the levels of pollution. Here we present a tested and functional cost-effective method of using the foliar ac...

These variables were: temperature...

The complexity of today’s environmental problems has amplified to the point where we can no longer ignore the impact of human actions on the functioning of ecosystems. The process of Mapping and Assessing Ecosystems and their Services (MAES) promoted by the European Commission is considered a first step to achieve the good status of ecosystems and...

There are very few studies of the influence of heavy metal pollution on soil mite communities in European grasslands. The objectives of this study were to provide quantitative information about the diversity of the Acari in mountain grasslands and to establish the influence of heavy metal pollution on them. It was found that the species diversity a...

Eight invertebrate ‘groups’ were investigated having a total of 503 species, which can be divided into two major categories: above ground and below ground. The above-ground groups are the Coleoptera (beetles), Lepidoptera (butterflies and moths), Odonata (dragonflies and damselflies), Orthoptera (grasshoppers and crickets) and Thysanoptera (thrips)...

In the Transylvanian region, the Arie Valley stretches along the course of the Arie River, ending as tributary of Mure River. As well as these areas of great biodiversity value, the Arie Valley (drainage area of 2,540 km 2) also crosses the region where local people set their villages and towns and use the surrounding areas as grasslands for grazin...

In 2013–2014, the soil mite communities from six overgrazed grassland ecosystems located in the Trascău Mountains, Romania, were investigated. Forty-six species were identified, with 645 individuals. Some abiotic factors from soil were measured (soil temperature – T, soil water content – H, soil acidity – pH, carbon content – C, total nitrogen – Nt...

The plant species diversity of grasslands was studied from the former time due to the usage of the grasslands mainly as pastures for grazing and hay productions. In the Transylvanian region, Paul rivulet flows into the Ampoi River, a tributary of the Mureș River. Paul catchment area was affected over time due to atmospheric deposition from Zlatna e...
