“…This concurs with previous studies that have demonstrated that consistent conservation activities in local communities positively influence the preservation of wildlife species (Akenji et al, 2019;Breuer & Mavinga, 2009;Nicholas et al, 2010;Tranquilli et al, 2014). is scarce, gorillas have tendency to build nests in trees (Furuichi et al, 1997).…”

Distribution, habitat use and human disturbance of gorillas (Gorilla gorilla) in the Ebo forest, Littoral Region, Cameroon

Great apes are threatened by many factors including habitat loss, forest degradation and disease. Despite the improved understanding of the distribution of gorillas in Cameroon, there is a lack of fine-scale knowledge about their habitat use. We used the Kernel Density Estimate method combined with grid cell counting to assess gorilla distribution, habitat use and human disturbance on one of the least studied gorilla populations in Cameroon. Proportions of different habitat types in the landscape were quantified using classification and regression tree approach applied to Landsat-8 and digital elevation model data. We found that the distribution of gorillas was restricted to the central band of the site (~22 km 2 ). Although the area was dominated by mature forest, the goodness-of-fit test showed that gorillas used grassland areas more frequently. Intensive human activities were noted across the gorilla range, with used cartridge shells being the most evidence hunting sign. Our results can be used to guide conservation and sustainable development stakeholder decisions in the area.With increasing anthropogenic threats throughout the landscape, we recommend the implementation of noninvasive research activities focusing on threat monitoring, nesting and dietary ecology, and the promotion of community-led conservation initiatives to reduce pressure on the gorilla habitat.

“…The densities of gorillas and chimpanzees in a portion of Loango National Park that includes our study area (101-123 km 2 ) were estimated using genetic capture-recapture methods, with 0.8-1.1 chimpanzees and 1.2-1.4 gorillas per km 2 50,51 . These estimations of chimpanzee density are moderate compared to other field sites where the two species occur sympatrically, while the gorilla densities are significantly lower (but see variety of methods used, e.g., 48,[52][53][54] ).…”

Lethal coalitionary attacks of chimpanzees (Pan troglodytes troglodytes) on gorillas (Gorilla gorilla gorilla) in the wild

Intraspecies violence, including lethal interactions, is a relatively common phenomenon in mammals. Contrarily, interspecies violence has mainly been investigated in the context of predation and received most research attention in carnivores. Here, we provide the first information of two lethal coalitionary attacks of chimpanzees (Pan troglodytes troglodytes) on another hominid species, western lowland gorillas (Gorilla gorilla gorilla), that occur sympatrically in the Loango National Park in Gabon. In both events, the chimpanzees significantly outnumbered the gorillas and victims were infant gorillas. We discuss these observations in light of the two most widely accepted theoretical explanations for interspecific lethal violence, predation and competition, and combinations of the two-intraguild predation and interspecific killing. Given these events meet conditions proposed to trigger coalitional killing of neighbours in chimpanzees, we also discuss them in light of chimpanzees’ intraspecific interactions and territorial nature. Our findings may spur further research into the complexity of interspecies interactions. In addition, they may aid in combining field data from extant models with the Pliocene hominid fossil record to better understand behavioural adaptations and interspecific killing in the hominin lineage.

“…However, such initiatives will only be successful through collaboration of local stakeholders, government officials, conservation agencies, and industrial partners. It has been previously asserted that chimpanzees prefer primary forest (Tutin and Fernandez, 1984;Furuichi et al, 1997), whereas primary lowland forests were thought to be insufficient in terrestrial herbaceous vegetation to support high gorilla numbers (Schaller, 1963;Groves, 1971). The intact Ndoki forest can be considered a climax forest with a high vertical canopy structure created by light-demanding pioneer species such as mahogany (Entandrophragma spp.)…”
