Article
The rapidly growing human population in West Africa has generated increasing demand for agricultural land and forest products. Consequently 90% of the original rainforest cover has now disappeared and the remainder is heavily fragmented and highly degraded. Although many studies have focused on carbon stocks and fluxes in intact African forests, li...

Understanding how trees mediate the effects of chronic anthropogenic disturbance is fundamental to developing forest sustainable management strategies. The role that intraspecific functional diversity plays in such process is poorly understood. Several tree species are repeatedly defoliated at large scale by cattle breeders in Africa to feed livest...

Long-term effects of liberation thinning on crop trees species (commercial species) were analysed in an evergreen forest and a semi-deciduous forest in Ivory Coast. This silvicultural treatment consisted in removing only the seed trees of non-commercial species in order to enrich the forest stand into commercial species through the increase of crop...

En Côte d’Ivoire, pour appuyer les politiques de réduction de la déforestation et mieux comprendre les dynamiques en cours, des cartographies fines et régulières des changements d’occupation et d’usage des terres sont nécessaires. Cependant, ces études sont rarement conduites sur de grands territoires ou elles sont parfois obsolètes à cause de la r...

The latitudinal diversity gradient (LDG) is one of the most recognized global patterns of species richness exhibited across a wide range of taxa. Numerous hypotheses have been proposed in the past two centuries to explain LDG, but rigorous tests of the drivers of LDGs have been limited by a lack of high-quality global species richness data. Here we...
Article
Full-text available
The fight against deforestation and forest degradation is now a major challenge for the preservation of global forest ecosystems. The remote sensing forest monitoring methods that are currently deployed are not always adapted to the Ivorian context because of the high cloud cover, diversity of shaded crops, and land clearing techniques. This study...
Article
Full-text available
One of the most fundamental questions in ecology is how many species inhabit the Earth. However, due to massive logistical and financial challenges and taxonomic difficulties connected to the species concept definition, the global numbers of species, including those of important and well-studied life forms such as trees, still remain largely unknow...
Article
Full-text available
Significance Tree diversity is fundamental for forest ecosystem stability and services. However, because of limited available data, estimates of tree diversity at large geographic domains still rely heavily on published lists of species descriptions that are geographically uneven in coverage. These limitations have precluded efforts to generate a g...
Article
Full-text available
En Afrique tropicale, dans les plantations forestières, la majorité des espèces autochtones ont été délaissées au profit d’espèces exotiques à croissance initiale rapide. Cette tendance est encore plus marquée dans les zones soudanienne et soudano-guinéenne à longue saison sèche. Ainsi s’explique le manque de connaissances sur les potentialités et...
Article
Full-text available
In West Africa, more than 80% of the original forest cover has disappeared due to the exponential growth of human populations in a recurrent search for new agricultural land. Once the fertility of the land is exhausted, these areas are abandoned and left to be reforested through natural succession. Despite the widespread presence of secondary fores...

Full-text available
In Côte d'Ivoire, more than 80% of the original forest cover has disappeared due to slash-and-burn shifting agricultural practices, uncontrolled logging, and large-scale land conversion for cash crop cultivation. Yet the demand for timber continues to grow and cannot be met by the scarcity of tree plantations. Despite the widespread presence of sec...

En Côte d’Ivoire, plus de la moitié du couvert forestier (57 %) a disparu en un quart de siècle (1990-2015) avec une perte importante de biodiversité. Pour mieux comprendre les dynamiques en cours et appuyer les politiques de réduction de la déforestation, des cartographies fines et régulières des changements d’occupation et d’usage des terres sont...
Article
Full-text available
Most of the West African forests have disappeared or have been deeply fragmented. This deforestation dynamic is still ongoing under a strong demographic pressure, forests being mostly replaced by agricultural lands. On the other hand, some reforestation projects are also undertaken, in particular by planting non-native species like Cedrela odorata....

Aim Palms are an iconic, diverse and often abundant component of tropical ecosystems that provide many ecosystem services. Being monocots, tree palms are evolutionarily, morphologically and physiologically distinct from other trees, and these differences have important consequences for ecosystem services (e.g., carbon sequestration and storage) and...

Article
The rapidly growing human population in sudanian West Africa has generated increasing demand for agricultural land and forest products so that most of the original vegetation cover has disappeared and the remainder is highly degraded, meaning that it is urgent to draw up a long-term assessment of the potential of local species to be promoted in pur...

Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research sp...

En forets naturelles, la recherche de la rentabilite economique constitue une preoccupation essentielle. Ainsi, les sylviculteurs concentrent-ils le plus souvent leurs interventions en vue de stimuler et d'accroitre la dynamique des especes commerciales au detriment des especes non commerciales. L'efficacite de ces interventions sylvicoles a deja e...
