    Seasonal Changes on Termite Foraging Behaviour under Different Habitats in Rufiji District Tanzania.
    (2013) Materu, Christopher; Yarro, Jacob; Nyundo, Bruno A.
    The effect of wet and dry season on termites foraging was examined in cropland, forest and grassland in Rufiji district for a period of one year. Termites species richness as well as abundance were sampled using standardized transect lines. Sampling was carried out on monthly basis. Termite species abundance was significantly different between the three locations, but species richness was not significantly different. These results reveal that termite abundance was higher in disturbed habitat due to the removal of vegetation which denies termites food and areas for nesting. Furthermore movement of termites from lower horizons during the wet season was higher than in the dry season.

    Termite (Isoptera) Assemblages in Rufiji District Tanzania
    (2013) Materu, Christopher L.; Yarro, Jacob; Nyundo, Bruno A.
    Different land uses tend to affect termite feeding groups, abundance and species richness. Termites play a major role in the ecosystem particularly decomposition process, carbon and nitrogen cycling. Termite diversity differs between habitats depending on human activities. The main objective of this study was to investigate termite assemblage under different land use. Termites were sampled with a standardized 100m × 2m straight-belt transect at three named habitats. The difference in feeding groups was statistically not significant. Though termite feeding group variations across habitats were caused by human activities but changes were not high enough to cause significant differences. The results from this study provide a database on termite feeding groups which will be useful for future research in the district.
