Journal of Quaternary Science, EarlyView.ABSTRACT This paper examines regional and chronological variations in Acheulean handaxe morphology during Marine Isotope Stage 11 (c. 425–365 ka BP) in Britain. Using a data set of 737 handaxes from 13 securely dated sites in East Anglia and the Thames Valley, we apply three‐dimensional geometric morphometric analysis to examine morphological ...

Phosphorus flux by macrobenthic invertebrates in a shallow eutrophic lake Donghu: spatial change
Knowledge and Management of Aquatic Ecosystems, 2011 We estimated phosphorus flux mediated by benthic invertebrates from the sediments to the water in a shallow eutrophic lake (lake Donghu, central China) and quantified spatial (littoral and central sites) and specific (among different ...

Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age
Journal of Quaternary Science, EarlyView.ABSTRACT Disentangling climate variability and human activity in past nitrogen cycling is key to understanding ecosystems. Previous studies in Ireland observed a widespread, permanent shift in terrestrial nitrogen cycling during Later Prehistory, potentially linked to intensifying land‐use.

Planktonic Respiration in a Shallow Eutrophic Lake
Journal of Freshwater Ecology, 2006 ABSTRACT We studied the relationships between planktonic respiration and key physicochemical parameters and total autochthonous biomass for three years in Lake Pamvotis, a shallow and eutrophic Greek lake. Planktonic community respiration was correlated with only one environmental parameter, dissolved inorganic nitrogen concentration, which appeared to

Invertebrate communities in northern Lake Victoria, with reference to their potential for fishery production [PDF]
, 1999 The zooplankton and macrobenthic communities of Lake Victoria were sampled by lift net and Ponar grab, respectively. The zooplankton comprised copepods and cladocerans, rotifers and aquatic insect larvae. Most taxa exhibited wide distribution in the lake,

Journal of Quaternary Science, EarlyView.ABSTRACT Like other perialpine basins and glaciated margins, the Geneva Basin in SW Switzerland is characterised by buried tunnel valleys, which are elongated incisions widely attributed to subglacial meltwater erosion beneath continental ice sheets. However, an inclusive understanding of the geological control on the evolution of the glacial landscape

Wind-driven currents in a shallow lake or sea [PDF]
For shallow lakes and seas such as the great lakes (especially Lake Erie) where the depth is not much greater than the Ekman depth, the usual Ekman dynamics cannot be used to predict the wind driven currents.

Sediment phosphorus flux in Beaver Lake in Northwest Arkansas [PDF]
, 2010 Internal phosphorus (P) loading may influence primary production in lakes, but the influence of sediment-derived P has not been well studied in Beaver Lake of Northwest Arkansas.

Land Degradation &Development, EarlyView.ABSTRACT Vegetation succession in aquatic and littoral habitats has received much less attention than terrestrial habitats have. We sampled differently aged successional stages at five different types of post‐mining sites, that is, sandpits, stone quarries, clay quarries, brown coal spoil heaps and black coal subsidences, across the Czech Republic ...
