Table 2 Overview of results investigating within- and between-group competition in Bwindi gorillas inferred from space use parameters across several spatial and temporal scales

From: Using long-term ranging patterns to assess within-group and between-group competition in wild mountain gorillas

Predictor variable Group size Local gorilla population densitye Intergroup encounter (yes/no) Previous use by neighboring gorilla groups Number of males Core area (yes/no)
Response variable
 Daily travel distancea No No Yes  
 Monthly home range sizea No Yes No  
 Revisit frequency to each part of the annual home rangea, c Yes Yes No  
 Annual home range size Yes   
 Annual home range fidelity Yes  
 Annual home range exclusivity Yes Yes Yes
 Utilization of areasb,d Yes  
  1. aTaken from Seiler et al. [54]
  2. bTaken from Seiler et al. [26]
  3. cCorresponds to the number of times that each group of gorillas (n = 13) entered each 500 × 500 m grid cell within a group’s home range during a one year study period
  4. dCorresponds to the distance travelled by each gorilla group (n = 10) in each 500 × 500 m grid cell during a one year study period
  5. eThis variable represents the weighted size of the Bwindi mountain gorilla population except the group. Therefore, the larger this estimate, the more neighboring gorillas can be found near a group
