Microplastic pollution has gained attention in recent years due to its adverse impact on the environment. As a major threat marine ecosystems and biota, accumulation of microplastics along coastlines become growing concern. This study focused quantifying characterizing presence, distribution, composition beaches Romania Bulgaria. Microplastics were extracted from beach sand samples using saturated NaCl solution. The particles then analyzed through FT-IR DSC spectral analyses identify their...
Integrated coastal zone management proposes nature-based mitigation strategies based on the replacement of artificial stabilization and protection structures with dunes stabilized plant species. These psammophytes stabilize sands act as supporters, increasing dunes’ ability to reduce storm damages effectively minimize erosion minimal negative impacts natural ecosystems. That is why searching for native salt-tolerant plants extensive root systems studying their capacity flooding control...
: Intestinal colonization by multidrug-resistant (MDR) bacteria is considered one of the main risk factors for invasive infections in hematopoietic stem-cell transplant (HSCT) setting, associated with hard-to-eradicate microorganisms. The aim this study was to assess rate intestinal MDR and their microbial spectrum a group post-HSCT patients genetic determinants beta-lactam glycopeptide resistance recovered isolates, as well determine epidemiological relation between them.
Palaeoenvironmental data from the high-resolution spore-pollen analysis of laminated sediments newly-taken Core 3 ‐ Varna Lake were combined with analyses dinoflagellate cysts, acritarchs and other non-pollen palynomorphs (NPP), including fossil algal fungal remains. The location core is close to submerged prehistorical sites permits palaeoenvironmental correlations obtained results available archaeological geochronological data. established Age Model shows that accumulation lake started...
Leymus racemosus (Lam.) Tzvelev subsp. sabulosus (M. Bieb.) (mammoth wildrye) and Ammophila arenaria (L.) Link (marram grass) are perennial, psammophilous species which dominate sand dunes due to their biological characteristics. Their communities have an important role in the formation of natural vegetation cover coastal strips along Bulgarian Black Sea Coast. This study provides first systematic analysis tolerance L. A. sea water immersion It aims determine effects flooding stress on whole...
Markov G. N. & Vergiev S. 2010. — First report of cf. Protanancus (Mammalia, Proboscidea, Amebelodontidae) from Europe. Geodiversitas 32 (3): 493-500.Three molars northeast Bulgaria are attributed to sp., based on their distinctive morphology. These the first finds Europe referable amebelodontid genus Protanancus, hitherto known Africa and Asia. The material NE differs both named species genus, P. macinnesi chinjiensis, displaying a combination derived primitive characters.
Coastal habitats are highly threatened ecosystems that sensitive to complex sets of natural and human drivers. Europe's coastal protected from damage due activity by the EU Habitats Directive, required be mapped within flood risk assessments Floods Directive. Ecological vulnerability a common way assessing impacts on these therefore often include habitats. Flood also evaluate, where relevant, mitigation services provided The two aspects - their service ecological strongly correlated; however...
Unusual storms along the Bulgarian Black Sea Coast may cause flooding, erosion and therefore destruction of plant communities psammophytes which dominate sand dunes. In such cases Galilea mucronata (L.) Parl. occupies territories from dune pioneers becomes a major stabilizer. This study aims to establish viability this species possible negative consequences during simulated flooding experiments thereby investigate its capacity as Conducted established that G. was very tolerant immersion...
A holistic approach to sustainable coastal zone management assigns the development of nature-based and low-cost strategies for protection during extreme meteorological events. This determines growing interest in plant species with high salt tolerance, study their flood resilience order determine capacity flooding erosion control. Bermudagrass (Cynodon dactylon (L.) Pers.), its vast rhizome system, has major characteristic features useful stabilisers sand dunes. aims define effects stress...
The aim of the present study is to reconstruct palaeoclimate variables in North-Eastern Bulgaria during last 7000 years, based on pollen analysis from 2 lacustrine cores and using modern analogue technique (MAT). Pollen data were used for reconstruction four parameters: average annual temperature, temperature warm cold half-year precipitation.
The climate in the area is transitional between fully humid, warm temperate and Mediterranean with a mean annual precipitation of about 500–600 mm maximum autumn–winter seasons, a...
Mucormycosis, caused by the widespread molds of Mucorales order, is an insidious infection that manifests in different clinical forms. Even most benign form, cutaneous mucormycosis, can present with severe complications and a fatal outcome patients suppressed immune system underlining comorbidities. We rare case proven primary multifocal mucormycosis child newly diagnosed acute leukemia without multiorgan dissemination. Various laboratory techniques (histopathological, cultural...

The aim of the present study is to reconstruct palaeoclimate variables in Durankulak Lake Region (Northeastern Bulgaria) during last 6000 years, based on pollen analysis from lacustrine core DK-1 and using modern analog technique (MAT). Pollen data was used for reconstructions four parameters: average annual temperature, temperature warm cold half-year precipitation. Three climatic intervals were defined. During first interval (6000–5000 cal. BP), highest values thermal parameters recorded,...
Sustainable development of coastal areas recommends nature-based solutions for erosion and flooding control such as planting transplanting techniques instead artificial stabilization protection structures. In order to compare the capacity well adapted plant species with extensive root systems, a multidisciplinary study based on GIS mapping modelling seven sites over Bulgarian Black Sea Coast. Three hand-planted polygons were monitored compared natural ones. A strong correlation between...
The aim of the present study is to reconstruct palaeoclimate variables in Beloslav Lake Region (Northeastern Bulgaria) during last 6000 years, based on pollen analysis from lacustrine core Bel-1 and using modern analog technique (MAT). Pollen data was used for reconstructions four parameters: average annual temperature, temperature warm cold half-year precipitation.
Sustainable development of coastal systems and low-laying inland areas require replacement artificial stabilization protection structures with “soft” transplanting techniques native, salt-tolerant plant species. They can effectively minimize erosion reduce storm damages minimal negative impacts to natural ecosystems. Ecosystem services searching for well adapted plants extensive root studying their ability flooding control. Although, the Bulgarian Black Sea Coast is relatively protected from...
The present paper proposed a rapid method for vulnerability assessment of coastal plant communities from flooding caused by unusual storms over the Bulgarian Black Sea Coast. model was tested and applied on Kabakum beach, Varna (Northeastern Bulgaria) 2018 year. In order to create dynamic GIS model, data experimental results detailed mapping beach (Varna) were incorporated. As result simulated experiment, Critical Decomposition Time (CDT) obtained. Linking flood duration with CDT altitudinal...
