Exam Practise

Home range is an area that an animal goes on a daily basis and live on normally, and the animal does not need to defend it against predator.

Daily range compared to home range - The daily range tend to be smaller  this is because it only their daily range.
Rainfall impact on home range size. Rainfall affected the home range sizes either by decreasing the resources for olive baboons. Because the 400-600 yearly rainfall (mm) the home range approximate increases by 43.8 size (km). This is because their habitat is so dry, not enough resources. This causes the Olive Baboons to spread out in order to hunt for resources or food. However at a habitat where rainfall is common for example around 2000, the resources will get enough water from the rain. This means the home range will be small, because they get enough resources that they don’t need to spread out. To search for food.

Rainfall impact on daily range size. Looking at the data table daily range(km) is more spread out at places where there is not much rain. For example from the data table Yearly range of 400-600 will have 5.64 daily range while yearly rainfall 2000 daily range 0.3-2.0 km. This is because more rainfall means better resources, with places that receives more rain means their daily range will be small as they don't have to get far in search of food. Whilst with limited rainfall the daily range will be bigger because the Olive Baboon will have to get far in order to get enough resources.

  1. Hi Lana, this is a good start for this question. Here is some feedback!

    Home ranges are definitely areas where animals move on a daily basis (to find resources by foraging, hunting, finding water, etc). They don't defend it against members of the same species they meet in their home range (unlike territories, which they may defend).

    However, while they're out in their home range (depending on the species) there still might be some competition for resources, or they could still encounter predators trying to eat them and have to defend themselves aggressively!

    Your paragraph on how rainfall affects the habitat (by the higher rainfall changing the habitat to a wetter, more healthy, lush forest that can support more life that could be food for the baboons) and therefore affects the size of the home range (smaller, because the resources are denser).

    You could also talk about intraspecific competition between members of the same species in each baboon group.
