Abstract:

The Srebarna Nature Reserve is a wetland with great conservation value. The dispersal of aquatic bugs in it has not been studied earlier. Acquiring more data about the aquatic bug’s species composition and dispersal activity is a prerequisite for future studies on phenology or faunistic studies of the group in the wetland. In the present paper, aquatic bugs attracted to UV light near the Srebarna Nature Reserve were quantified. A total of 4589 individuals of aquatic bugs (Heteroptera, Nepomorpha) were collected during 11 nights of light trapping. Dispersing aquatic bugs were almost exclu

Abstract:

The Srebarna Lake is a shallow floodplain lake in NE Bulgaria, on the right bank of the Danube River, biosphere and managed reserve. Due to its importance as a unique ecosystem with diverse habitats and species richness it was designated as a Ramsar site (The Convention on Wetlands, RAMSAR. 1975), UNESCO Biosphere Reserve (Reserve 1977), a Monument of World Cultural and Natural Heritage (Heritage 1983), an Important Bird Area (Area 1989) and Natura 2000 protected zone (Natura 2000 protected zones 2008).The lake is characterized by an unstable water level, highly dependent on the level of the D

Abstract The Srebarna Lake Biosphere Reserve is a protected natural site of national and international significance. It characterizes with extremely high biodiversity, being one of the last wetlands along the Lower Danube preserved in relatively natural state; the lake area is NATURA 2000 site. This study was designed to further research on the impact of intensive agriculture on the lake’s ecological status. First task was to find an evidence for link between intensive agriculture and the loading of the lake with nutrients. The second was a study on the PAH’s penetration into the lake ecosyste

The aim of the study was to compare in situ and remote sensing data, in order to assess the applicability of satellite images in water quality monitoring of floodplain lakes. Two indicators of trophic status were compared: chlorophyll a and total suspended matter. Two lakes on Lower Danube floodplain were selected: Srebarna and Malak Preslavets. Data were obtained in July and August 2018. Sentinel 2 MSI L1c images were analyzed in SeNtinel Application Platform (SNAP), (v. 6.0).

Determination of stocks of aboveground phytomass of reed communities in Bulgaria is not well studied yet. This survey is the most detailed study on the stocks of the aboveground phytomass of the reed communities (<em>Phragmites australis</em> (Cav.) Trin. Ex Steud.) in Bulgaria. The studied reed beds are formed in the floodplain part of the Danube River. They are located in the fluvial terrace of the river between Archar Village (west) and Srebarna Village (east). As a result of the survey, it was found that the average stocks of the aboveground phytomass of the reed communities reached to 19.

The world is currently facing the challenge of providing water, energy, and food for all. Scarce natural resources and the environment are increasingly being exploited, while at the same time the

The cyanobacterial biovolumes we found, determine three of the lowland water bodies: Onogur Reservoir (OR), Asparuhov Val Reservoir (AVR), and Srebarna Lake (SL) as “Alert Level 1” of potentially hazard
