Geophagy among primates: adaptive significance and ecological consequences
It is concluded that mineral supplementation, adsorption of toxins, treatment of diarrhoea and pH adjustment of the gut seem the most plausible reasons why primates engage in geophagy.
Geochemistry and mineralogy of soils eaten by humans
Earth samples (soils and parent materials) eaten by humans on three continents were analyzed chemically and mineralogically. Samples from Changsha county, China, are from three sites and were used as
Comparative scanning electron microscopy study of oriented till blocks, glacial grains and Devonian sands in Estonia and Latvia
Samples of Middle Devonian (Eifelian age; 387–380 Ma) indurated and non-cemented sandstone were compared with Pleistocene basal tills in Estonia and Latvia to test a hypothesis that glacial SEM
Quantification of SEM microtextures useful in sedimentary environmental discrimination
Scanning electron microscopic imagery is often used to identify and discriminate among environments of sedimentation with the main aim of identifying individual microfeatures, or suites of
Geochemistry and clay mineralogy of termite mound soil and the role of geophagy in chimpanzees of the Mahale Mountains, Tanzania
These analyses and preliminary observations linking geophagy with instances of severe diarrhea, and other signs of gastrointestinal upset in the Mahale chimpanzees, suggest that one function for the ingestion of this substance by chimpanzees may be to help provide temporary relief from gastrointestinal ailments.
Mineral and chemical analyses of soils eaten by humans in Indonesia
Five Javanese soil samples, including three earths eaten by humans as therapeutic medicine, were analyzed for their physical, mineral and chemical properties along with suitable control samples (not
Quaternary and Environmental Research on East African Mountains
Twenty-six papers form a summary of research on glacial history, paleoclimatology, biogeography, ecosystem disequilibrium. Focus is on detailed chrono-stratigraphic, glacial geologic, and vertebrate
