Home-range size of the bare-ear marmoset (Callithrix argentata) at Alter do Chao, Central Amazonia, Brazil
We studied factors affecting variation in home-range size of four groups of bare-ear marmosets (Callithrix argentata) in patches of forest within a central Amazonian savanna. We determined relative use of different parts of the home range by radiotelemetry. We estimated fruit availability monthly in...
