Vlasac revisited: formation processes, stratigraphy and dating

open access: yesDocumenta Praehistorica, 2008
Since 2006, new excavations of the Mesolithic-Neolithic site of Vlasac in the Danube Gorges of the north-central Balkans have been under way. Excavations made across the surviving preserved portion of the site provide a unique opportunity for a re ...

Size estimations of sturgeons (Acipenseridae) from the Mesolithic-Neolithic Danube Gorges

open access: yes, 2020
The significant role of sturgeon fishing in the Mesolithic-Neolithic Danube Gorges has long been recognized, but the reconstruction of the sizes of individuals caught has been hindered by the lack of recent specimens from the Danube drainage in reference collections.

Post-impoundment biomass and composition of phytoplankton in the Yangtze River [PDF]

open access: yes, 2007
Damming, and thus alteration of stream flow, promotes higher phytoplankton populations and encourages algal blooms (density > 10(6) cells L-1) in the Three Gorges Reservoir (TGR). Phytoplankton composition and biomass were studied in the Yangtze River

When did the ‘Neolithic package’ reach Lepenski Vir? Radiometric and faunal evidence

open access: yesDocumenta Praehistorica, 2007
A recent dating program on animal bone samples from Lepenski Vir, along with faunal and various archaeometric analyses, allows us to suggest a new stratigraphic and chronological sequence for the Mesolithic-Neolithic site of Lepenski Vir in the north ...

Future large hydropower dams impact global freshwater megafauna [PDF]

open access: yes, 2019
Dam construction comes with severe social, economic and ecological impacts. From an ecological point of view, habitat types are altered and biodiversity is lost.

The Nišava river water quality as the indicator of the sustainable development of the city of Niš [PDF]

open access: yes, 2007
The Nišava river has a great importance for the sustainable development of the city of Niš. From the Mediana spring, which is on the bank of the Nišava, the city of Niš satisfies around 30% of its water demand.

River damming leads to decreased phytoplankton biomass and disappearance of cyanobacteria blooms [PDF]

open access: yes, 2014
The large Alqueva dam was built in the early 2000s in the Guadiana River (southern Portugal) and has highly controlled the freshwater flowing into the Guadiana estuary, leading to significant changes in the natural hydrological regime.

Early Life Conditions and Physiological Stress following the Transition to Farming in Central/Southeast Europe: Skeletal Growth Impairment and 6000 Years of Gradual Recovery. [PDF]

open access: yes, 2016
Early life conditions play an important role in determining adult body size. In particular, childhood malnutrition and disease can elicit growth delays and affect adult body size if severe or prolonged enough.

Applications of Coupled Explicit–Implicit Solution of SWEs for Unsteady Flow in Yangtze River [PDF]

open access: yes, 2017
In engineering practice, the unsteady flows generated from the operation of hydropower station in the upstream region could significantly change the navigation system of waterways located in the middle-lower reaches of the river.
