| Abstract: | Arvicanthis niloticus was radio‐tracked in the grasslands of the Queen Elizabeth National Park in Uganda. Home range sizes calculated by Ranges V® using the Minimum Convex Polygon Method (at 95%) were on average 5.5 times larger in the bushland–grassland mosaic than those in the Abutilon guineense–Ocimum suave bushland. An inverse relation between home range size and population density was found. In both habitats the species was highly active during daylight hours but differed in activity patterns. |
