Routes and long-distance traffic : the nodal points of Wulfstan's voyage [PDF]

, 2008
Wulfstan, author of the sole preserved contemporary description of the 9th-century southern Baltic littoral, is an enigmatic fi gure. From archaeology we have learned that the coast he followed was at this time speckled with trading ports, large and ...

River culture: How socio‐ecological linkages to the rhythm of the waters develop, how they are lost, and how they can be regained

The Geographical Journal, Volume 190, Issue 2, June 2024.
Short Abstract Much of the human culture in hydroscapes has developed as an adaptation to hydrological rhythms. Technological advances have allowed humans to control, change, or even eliminate these rhythms. Along with the failure of important ecosystem functions that may result, cultural activities may also decline.

Generation of High‐Resolution Water Surface Slopes From Multi‐Mission Satellite Altimetry

Water Resources Research, Volume 60, Issue 5, May 2024.
Abstract For nearly three decades, satellite radar altimetry has provided measurements of the water surface elevation (WSE) of rivers. These observations can be used to calculate the water surface slope (WSS), which is an essential parameter for estimating flow velocity and river discharge. In this study, we calculate a non time‐varying high‐resolution

A new MONERIS in-stream retention module to account nutrient budget of a temporary river in Cyprus [PDF]

, 2014
The nature of the nutrient budget for temporary rivers differs from that for permanent rivers because of the restricted nature of flow, the lack of adequate dilution, and weather conditions which are conducive to the development of algal blooms.

Functional structure and diversity of marine benthos reflect food availability and quality, as evidenced by isotopic diversity

Limnology and Oceanography, Volume 69, Issue 4, Page 757-771, April 2024.
Abstract Organic matter (OM) resources shape not only the trophic diversity of benthic communities but also the diversity of benthic functional traits. The resulting community structure has a direct effect on many ecosystem processes and functions.

Phenology of the aquatic fern Salvinia natans (L.) All. in the Vistula Delta in the context of climate warming

Limnologica, 2013
Abstract We determined the phenology and architecture of Salvinia natans life stages by observing permanent plots in the Vistula Delta (Baltic Sea Region, N Poland) biweekly from 2006 to 2010. Germination of macro- and microspores was initiated at 12.4 ± 0.2 °C water temperature corresponding to early-April water temperature in the Vistula Delta ...

Survival and reproduction of the aquatic fernSalvinia natans(L.) All. during expansion in the Vistula Delta, south Baltic Sea coast

Journal of Freshwater Ecology, 2013
In this study we examined the survival, reproduction, and population size of the aquatic fern Salvinia natans (L.) All. during its expansion in the Vistula Delta (south Baltic Sea coast, northern Poland) with observations every 14 days for five consecutive years at 10 permanent plots in one river.

A long-term study of stable isotopes as tracers of processes governing water flow and quality in a lowland river basin: the upper Thames, UK [PDF]

, 2016
A long-term study of O, H and C stable isotopes has been undertaken on river waters across the 7000 km2 upper Thames lowland river basin in the southern UK. During the period, flow conditions ranged from drought to flood.

Distribution, abundance and environmental conditions of the clonal aquatic fern Salvinia natans (L.) All. in the Vistula delta (Baltic Sea Region)

Biodiversity: Research and Conservation, 2012
Abstract We examined the distribution, resources and environmental conditions of the clonal aquatic fern Salvinia natans (L.) All., expansive in the Vistula delta (N Poland). Before 2006, there were 7 stands of this species, while in the years 2006-2010 their number increased to 21. The most abundant populations were found in the rivers: Tuga (133.
