fossil diatoms
Fossil diatoms from the Milky River Formation of the Sandy Ridge section, Alaska Peninsula are analyzed.
      
The reconstructive TP level and the inference of aquatic plants from fossil diatoms in different lakes, as well as their comparison provide a scientific basis for ecological restoration of eutrophic lakes in research regions.
      
Effect of fossil diatoms on the growth of two syngeneic murine leukemias
      
The effect of micronized frustules of fossil diatoms (DS) on tumor growth and survival of mice receiving an ip inoculations of either a spontaneous lymphoblastic leukemia (LB) or P-388 lymphocytic leukemia (P-388) was investigated.
      
Inhibition of experimental autoimmune orchitis by fossil diatoms
      
Experimental autoimmune orchitis (EAO) induced in Swiss mice could be reduced by means of the utilization of micronized frustules of fossil diatoms (DS) containing 54% of SiO2.
      
Inferred ionic composition and salinity of a Bolivian Quaternary lake, as estimated from fossil diatoms in the sediments
      
Studies on fossil diatoms, chrysophytes, plant pigments, Cladocera and carbonaceous particles in a number of high altitude lakes in Italy and Switzerland have been used to track environmental changes.
      
Fossil diatoms document the late Cenozoic paleolimnologic and paleoclimatic history for the northwestern edge of the Basin and Range Province.
      
Fossil diatoms and the mid to late holocene paleolimnology of Lake Turkana, Kenya: a reconnaissance study
      
The biostratigraphy of fossil diatoms contributes important chronologic, paleolimnologic, and paleoclimatic information from Lake Baikal in southeastern Siberia.
      
Fossil diatoms were analysed from a 10.3 m core from Harris Lake, Cypress Hills, Saskatchewan, and a diatom-salinity transfer function was used to construct a history of Holocene salinity changes for the lake.
      
One part of this study included the analysis of the stratigraphy of fossil diatoms from a 17-metre sediment core dating back 8000 yrs.
      
In palaeoclimate research, fossil diatoms from saline lakes can be excellent indicators of past salinity, a proxy for climate change, although they are sometimes poorly preserved in sediment cores.
      
Limnological conditions in a subarctic lake (northern Québec, Canada) during the late Holocene: analyses based on fossil diatoms
      
A microwave digestion technique for the extraction of fossil diatoms from coastal lake and swamp sediments
      
This study provides an introduction to a microwave digestion technique for the extraction of fossil diatoms from sediments.
      
Preservation of fossil diatoms also depends on the degree of saturation of silica in the sediment porewater.
      
There are still huge gaps in our knowledge of fossil diatoms.
