野生マンドリルの移動パターンを解明 --直接追跡法と自動撮影カメラ法を組み合わせて説得力のある結論を得る--. 京都大学プレスリリース. 2021-11-26. / Movement is a fundamental characteristic of animals, but challenging to measure noninvasively. Noninvasive methods for measuring travel have different weaknesses, so multiple techniques need to be applied multiple techniques for reliable inferences. We used two metho...
The diversity and structure of plant communities are valuable indicators for assessing landscape quality. Land-use change is one of the main factors considered to affect and have the strongest impacts on biodiversity. In this study, we assessed the effects of the conversion of tropical dry forests and savannahs into agricultural lands on the floral...
La deforestazione è dovuta alla crescente domanda di prodotti agricoli e di biocarburanti: 10 miliardi di ettari l'anno secondo la Fao. Gli strumenti messi in atto dai Paesi del Nord e del Sud del mondo per fermarla entro il 2030, come previsto da Cop26.
Aim: Tree crowns determine light interception, carbon and water exchange. Thus, understanding the factors causing tree crown allometry to vary at the tree and stand level matters greatly for the development of future vegetation modelling and for the calibration of remote sensing products. Nevertheless, we know little about large-scale variation and...
Le débat sur le rôle des plantations forestières sur la protection des forêts naturelles et de la biodiversité associée est ancien et a pu faire l'objet de nombreuses controverses (Aubréville 1953). Cet article se propose d'y apporter sa contribution en prenant l'exemple de Madagascar.
The development of a sustainable wood energy chain is an essential part of ecological and energy transition in Reunion Island (Indian Ocean), where Acacia mearnsii is the main potential wood energy resource identified to date. In order to assess future wood biomass supply chain strategies, a major first issue is to gain knowledge of the spatial dis...
Le phénomène des " mégafeux " de l'été a attiré l'attention sur l'importance des forêts, en particulier les grandes forêts tropicales. Leur contribution écologique est menacée par divers facteurs et les politiques mises en oeuvre ne sont pas toujours à la hauteur des enjeux. La sauvegarde de ces forêts passe par des initiatives qui prennent davanta...
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...
Selective logging in tropical forests is often perceived as a source of forest degradation and carbon emissions. Improved practices, such as reduced-impact logging (RIL), and alternative timber production strategies (e.g. plantations) can drastically change the overall carbon impact of the wood production sector. Assessing the carbon balance of tim...
Logging is widespread in tropical regions, with approximately 50% of all humid tropical forests (1.73 × 109 ha) regarded as production forests. To maintain the ecosystem functions of carbon sequestration and timber supply in tropical production forests over a long term, forest management must be sustainable under changing climate conditions. Indivi...
