Activity, Distribution, And Density Of Brown Rats (Rattus Norvegicus) On Misali Island, Pemba Island, Tanzania, Raegan Hasselbring
Independent Study Project (ISP) Collection
This project investigated the activity, distribution, and density of brown rats (R. norvegicus) on Misali Island, Pemba. These factors were studied through field observations conducted over a 21-day observation period. Brown rats were highest in density around areas of human activity, attracted to the detritus, an ample food source. Although highest in density in these areas, a greater total population of brown rats was distributed in the coastal forest due to its proportion of area on the overall island. In the forest, the rats were most active along the coastal sections for unknown and unexplored reasons – possibly due to …
