The origin, migration and evolution of the Rapanui (Easter Islanders), has been contested for many years. Archaeological, linguistic and genetic/serological data have played instrumental roles towards resolving these disputes thus far. Several models have been developed which have addressed the origins of the prehistoric population that colonized Rapa Nui (Easter Island), with the results of these craniometric analyses compared to those expected patterns of variation and relatedness. The results indicate that the prehistoric Rapanui had the strongest affinities with the Gambier...

A succinct volume presenting current views of Rapanui prehistory, utilising biological evidence to modify existing archaeological and cultural anthropological preconceptions.

Bioenergy production from agricultural crop biomass or residues has gained interest recently due to the escalating cost of fossil fuels and the need to mitigate global warming caused by increasing GHG emissions. Of all the different feed stocks used for bioenergy production in Africa, cassava biomass potentially offers multiple benefits for producing biofuels such as biogas. This book, therefore, highlights the bioenergy (biogas) potential of the crop in Africa. The basic agricultural properties of cassava were discussed including its high carbohydrate content and total dry matter. Its...
