Because rapidly expanding human populations have devastated gorilla (Gorilla gorilla) and common chimpanzee (Pan troglodytes) habitats in East and West Africa, the relatively intact forests of western equatorial Africa have been viewed as the last stronghold of African apes. Gabon and the Republic of Congo alone are thought to hold roughly 80% of the world's gorillas and most of the common chimpanzees. Here we present survey results conservatively indicating that ape populations in Gabon… 
Will the Nigeria-Cameroon Chimpanzee Go Extinct? Models Derived from Intake Rates of Ape Sanctuaries
All great ape taxa are considered endangered due to a combination of habitat loss, hunting, disease outbreaks and human population increase. The bush-meat trade is thought to be the biggest threat to
Ape Abundance and Habitat Use in the Goualougo Triangle, Republic of Congo
Chimpanzee (Pan troglodytes troglodytes) and western gorilla (Gorilla gorilla gorilla) populations in central Africa are rapidly declining as a result of disease epidemics, commercial bushmeat
Regional action plan for the conservation of chimpanzees and gorillas in western equatorial Africa
This action plan represents a consensus of the world’s leading experts on the priority areas and priority actions needed for preserving wild chimpanzee and gorilla populations in western equatorial
The Critically Endangered western chimpanzee declines by 80%
The rate of population change for the western chimpanzee, Pan troglodytes verus, over a 24‐year period is assessed and a plea for greater commitment to conservation in West Africa across sectors is made.
Comparing ape densities and habitats in northern Congo: surveys of sympatric gorillas and chimpanzees in the Odzala and Ndoki regions
The results indicated that even the largest remaining ape populations in intact and protected forests are susceptible to sudden and dramatic declines, and the importance of intensifying monitoring efforts and further refinement of ape survey methods is emphasized.

Primate and ungulate abundance in response to multi‐use zoning and human extractive activities in a Central African Reserve
This study examines the abundance of key mammal species at the Dzanga-Sangha Reserve (RDS) in the Central African Republic with respect to conservation zoning and human activities in the reserve. RDS
Anthrax in Western and Central African great apes
The results show that diseases other than Ebola may also threaten wild great apes, and indicate that the role of anthrax in great ape mortality may have been underestimated, and suggest that risk identification, assessment, and management for the survival of the last great apes should be performed with an open mind.
Recovery Potential of a Western Lowland Gorilla Population following a Major Ebola Outbreak: Results from a Ten Year Study
The gorilla population visiting Lokoué forest clearing, Odzala-Kokoua National Park, Republic of the Congo, has been monitored before, two years after and six years after Ebola affected it in 2004, allowing us to describe Ebola's short-term and long-term impacts on the structure of the population.
Wild Bonobos and Wild Chimpanzees and Human Diseases
Reported effects of Ebola on western lowland gorillas in the last years of the Twentieth Century brought the underestimated threat that infectious diseases pose to wildlife to the forefront of the


Ebola and the decline of gorilla Gorilla gorilla and chimpanzee Pan troglodytes populations in Minkebe Forest, north-eastern Gabon
Data from nearby sites indicate that the epidemic was limited to the Minkebe Forest, and a catastrophic decline in ape populations in the area is believed to have been caused by a disease epidemic.
Nationwide census of gorilla (gorilla g. gorilla) and chimpanzee (Pan t. troglodytes) populations in Gabon
Gabon's large areas of undisturbed primary forest offer exceptional potential for conservation, not only of gorillas and chimpanzees, but also of the intact tropical rain forest ecosystems which they inhabit.
Is the gorilla a threatened species? How should we judge?
Status and conservation of primates in Odzala National Park, Republic of the Congo
Odzala National Park, Republic of the Congo has the highest recorded densities of western lowland gorilla and chimpanzee in Central Africa and may be a result of the high productivity of the forest and low poaching pressure.
Man determines the distribution of elephants in the rain forests of northeastern Gabon
Summary Dropping counts were used to assess elephant abundance in the remote forests of northeastern Gabon where there are few people and no logging. Elephants prefer the secondary forest which
Population density and nesting behaviour of lowland gorillas (Gorilla gorilla gorilla) in the Ngotto forest, Central African Republic
Compared with the gorilla population of the nearby Dzanga-Sangha forest, the population density of gorillas at Ngotto was lower but the proportion of nests found above ground was much higher and it is suggested that these differences were the result of the scarcity of herbaceous vegetation in the Ngotto forest.
What It Will Take to Monitor Forest Elephant Populations
Abstract: The decision by the Convention on International Trade in Endangered Species (CITES) to condition a limited sale of ivory on the status of elephant poaching has brought into sharp focus the
Roads, Development, and Conservation in the Congo Basin
Abstract: Road density is closely linked to market accessibility, economic growth, natural resource exploitation, habitat fragmentation, deforestation, and the disappearance of wildlands and
Ebola hemorrhagic fever outbreaks in Gabon, 1994-1997: epidemiologic and health control issues.
Yellow fever (YF) virus was first diagnosed in serum by use of polymerase chain reaction followed by blotting, and a vaccination campaign was immediately instituted, and EBO virus was found to be present concomitantly with YF virus in the epidemic.
African primates: Status survey and conservation action plan
This revised edition of the African Primate Action Plan (1986) provides a summary review of progress on projects originally recommended and gives recommendations for new projects in areas and on populations not previously included.
