In several regions of the Congo Basin the call of an endangered duiker is traditionally used by hunters to attract animals. We explore the possibility to standardize this call method to improve day time transect counts. Our study shows that the call is particularly efficient for the most common d...

Answering the call!: adapting a traditional hunting practice to monitor duiker populations
The impact of climatic changes that occurred during the last glacial maximum and the Holocene on vegetation changes in the Amazon Basin and the Guiana Shield are still widely debated. The aim of our study was to investigate whether major changes in vegetation (i.e. transitions between rainforests...

In this paper we seek to identify the floristic determination biases contained in large-scale commercial inventories conducted by logging companies and to determine whether this impacts on the observed patterns of alpha and beta diversity. The study focused on floristic data recently collected by...

Detecting large-scale diversity patterns in tropical trees: can we trust commercial forest inventories?
Management means allocating and distributing limited resources to achieve clearly defined targets. This definition helps towards a clear summary of the way ideas to do with forest management have been developing. Areas of concern have been gradually shifting form technical assignments (resource a...

Examples are used to illustrate the different present-day forms of forest management, based first and foremost on decision-making procedures governing management choices rather than on technical criteria governing the choice and implementation of programmes. These examples range from the Gabonese...

The various factors common to forest management schemes are examined : sustained output, biodiversity conservation, and multiple uses. These factors are combined in different ways from case to case. Consideration of them in the management process includes specific kinds of financial impact for ea...

Variations in the natural 13C abundance of soil organic matter (SOM) at different depths combined with SOM radiocarbon dating were used to reconstruct the history of the forest-savanna successions over the last millennium in the Gabon coastal area. A chronosequence was established by comparing th...

Tropical deforestation is leading to a loss of economically productive timber concessions, as well as areas with important environmental or socio-cultural values. To counteract this threat in Southeast Asia, sustainable forest management (SFM) practices are becoming increasingly important. We ass...
