Phytoplankton sinking rates in the Rhine region of freshwater influence
It is concluded that SetCol gives adequate results when incubations are performed at or near in situ irradiance and temperature; sinking rates are predominantly determined by cell or colony density rather than their size; periodic sedimentation is an important species-specific loss process for phytoplankton in the Dutch coastal zone.

Improved age control on early Homo fossils from the upper Burgi Member at Koobi Fora, Kenya.
To address questions regarding the evolutionary origin, radiation and dispersal of the genus Homo, it is crucial to be able to place the occurrence of hominin fossils in a high-resolutionExpand
Relevance of aquatic environments for hominins: a case study from Trinil (Java, Indonesia).
Knowledge about dietary niche is key to understanding hominin evolution, since diet influences body proportions, brain size, cognition, and habitat preference. In this study we provide ecologicalExpand
Plio-Pleistocene facies environments from the KBS Member, Koobi Fora Formation: implications for climate controls on the development of lake-margin hominin habitats in the northeast Turkana Basin
Examination of KBS Member facies environments from the Koobi Fora Ridge document the development of lake-margin hominin habitats in the northeast Turkana Basin and insights into potential climatic controls are given. Expand
Homo erectus at Trinil on Java used shells for tool production and engraving
A fossil freshwater shell assemblage from the Hauptknochenschicht of Trinil (Java, Indonesia) is reported, indicating that the engraving was made by Homo erectus, and that it is considerably older than the oldest geometric engravings described so far. Expand
The earliest occupation of north-west Europe: a coastal perspective
Recent discoveries from Pakefield and Happisburgh (Britain) have provided clear evidence for an unexpectedly early hominin occupation of north-west Europe. The sites, found in the deposits ofExpand
Middle Pleistocene climate and hydrological environment at the Boxgrove hominin site (West Sussex, UK) from ostracod records
The sediments of the Slindon Formation at the junction of the Chalk South Downs and the West Sussex Coastal Plain, as revealed and studied at Boxgrove, contain evidence for early Middle PleistoceneExpand
The influence of tidal straining and wind on suspended matter and phytoplankton distribution in the Rhine outflow region
Abstract To study the short-term effects of the physical environment on phytoplankton dynamics in the Rhine outflow area, changes in salinity, beam attenuation and phytoplankton distribution wereExpand
An astronomically-tuned climate framework for hominins in the Turkana Basin
Understanding the influence of orbital climate cycles on hominin evolution remains a key challenge in paleoanthropology. The two major unresolved issues are: the absence of a climate proxy yieldingExpand
The development of a Phaeocystis bloom in a mesocosm experiment in relation to nutrients, irradiance and coexisting algae
Abstract A widespread hypothesis is that man-induced eutrophication, an increase in nitrogen and/or phosphorus rather than silicon, gives a competitive advantage to the non-silicon using flagellatesExpand
