: The cedar oak forest of the Middle Atlas in Morocco is not only the last of the large forests in the southern Mediterranean, but it also contains all the surviving forest biodiversity. This forest has been severely affected by drought, overgrazing by mixed herds of goat and sheep, and excessive logging for timber, firewood, and livestock fodder. Recently, cedar bark stripping by Barbary Macaques (   Macaca sylvanus) has begun to have an effect on the forest. We investigated this behavior by… Expand

Damage to forest plantations by tufted capuchins (Sapajus nigritus): Too many monkeys or not enough fruits?
Results suggest that S. nigritus tree damage is primarily related to seasonal fluctuations in fruit and seed availability, and short term remediation strategies based on forestry management may be effective. Expand
Decline of the Endangered Barbary macaque Macaca sylvanus in the cedar forest of the Middle Atlas Mountains, Morocco
Abstract The Barbary macaque Macaca sylvanus, categorized as Endangered on the IUCN Red List, is the only macaque species found outside Asia. Conservation concern for the species arises from habitatExpand
Primates bark-stripping trees in forest plantations – A review
A literature review of why primates bark-strip trees in plantations is that they consume soft bark when or where their natural food is scarce concluded that a management method based on diversionary feeding could alleviate the damage produced by primates to coniferous trees of commercial value.

Seasonal dynamics in understorey abundance and carbohydrate concentration in relation to browsing and bark stripping of Tasmanian Pinus radiata plantations
Abstract Bark stripping in Pinus radiata plantations by Bennett’s wallaby (M. rufrogriseus subspecies rufrogriseus) triggers high rates of tree mortality and reduces crop productivity, causingExpand
Increasing Drought Sensitivity and Decline of Atlas Cedar (Cedrus atlantica) in the Moroccan Middle Atlas Forests
It is suggested that Atlas cedar forests that have experienced severe drought in combination with grazing and logging in the past may be in the process of shifting dominance toward more drought-tolerant species such as Q. rotundifolia. Expand
Tree growth decline on relict Western-Mediterranean mountain forests: Causes and impacts
Climate variability and land-use modifications are among the main components of global change, but their combined effects on forests have rarely been addressed. Relict tree species from theExpand
Modelling the susceptibility of pine stands to bark stripping by Chacma baboons (Papio ursinus) in the Mpumalanga Province of South Africa
Abstract Context. Commercial pine (Pinus spp.) plantations in southern Africa have been subjected to bark stripping by Chacma baboons (Papio ursinus) for many decades, resulting in severe financialExpand
A survey of the Endangered Barbary macaque Macaca sylvanus in the Central High Atlas Mountains of Morocco
Abstract The Barbary macaque Macaca sylvanus is the only macaque in Africa. The species is categorized as Endangered on the IUCN Red List and is listed in CITES Appendix II. This macaque has a relictExpand
Population decline of Macaca sylvanus in the middle atlas of Morocco
Abstract An eight-year-long census and habitat evaluation of the Macaca sylvanus population was conducted in a 484-km2 area of the central region of the Middle Atlas Mountains in Morocco between JuneExpand
Bark stripping by chacma baboons (papio ursinus) in relation to daily patterns of activity, feeding behaviour and home range in a pine plantation in Eastern Zimbabwe
This study reports daily activity pattern, home range size, daily travel distances and feeding behaviour for a troop of chacma baboons (Papio hamadryas ursinus) inhabiting a pine plantation inExpand


Food resources of the wild Barbary macaque (Macaca sylvanus) in high‐altitude fir forest, Ghomaran Rif, Morocco
A comparison of the study area with the prime habitat of the Barbary macaque-the high-altitude cedar forests of the Moroccan Moyen Atlas-indicates that climate and vegetation physiognomy are highly similar in both regions. Expand
The Feeding Ecology of the Barbary Macaque and Cedar Forest Conservation in the Moroccan Moyen Atlas
Since the early 1920s most studies on the Barbary macaque have been broad surveys of the geographic distribution of the species (see Taub, 1977 for references). The first detailed work on thisExpand
The Distribution and Current Status of the Barbary Macaque in North Africa
Barbary macaques (Macaca sylvanus L.) are now found in relatively small and disjunct habitat pockets in the Rif, Moyen and Haut Atlas mountain ranges of Morocco, and in the Chiffa, Petite and GrandeExpand
Population dynamics of Macaca sylvanus in Algeria: An 8‐year study
The demography and dynamics of two groups, one living in an evergreen cedar‐oak forest (Tigounatine) and the other, in a deciduous oak forest (Akfadou) in Algeria, were studied from 1982 to 1990.Expand
Habitat, density and group size of primates in a Brazilian tropical forest.
Both group sizes and population densities for the 5 species were generally lower at the Reserva Biologica Augusto Ruschi than those reported in other areas of Atlantic forest. Expand
Deforestation and reforestation: perspectives to reduce human caused desertification
This paper presents the results of the Symposium on “Deforestation and reforestation: The Atlas Project”. From the studies presented appeared that at present the causes od deforestation do not ariseExpand
An Ecological Model of Female-Bonded Primate Groups
A model is presented to account for the evolution of FB groups in terms of ecological pressures on female relationships and suggests that relationships in most FB groups are ultimately related to feeding competition. Expand
Geographic Distribution and Habitat Diversity of the Barbary Macaque Macaca sylvanus L.
During a 15-month behavioral study in Morocco and a 3-month survey in Morocco and Algeria, the present distribution of the Barbary macaque was determined. In Algeria, monkeys are found in seven constr
