The aim of this paper is to demonstrate the role of termites as soil forming agent in the tropical semi-deciduousforest. This is done by describing soil profiles, and by analysing soil samples from the soil profiles as well as soil material
Le régime alimentaire de Macaca sylvanus dans différents habitats d'Algérie: I.-Régime en chênaie décidue. (The diet of Macaca sylvanus in various Algerian habitats. I. The diet in deciduous oak forest)
The preliminary results of long-term CO2 flux measurements at forest sites in East Asia are explained and compared with each other. The features of seasonal variation of CO2 fluxes are different among deciduous-broadleaf, evergreen-coniferous
, deciduous-coniferous and tropical forests in East Asia, and the causes of difference are discussed.
A model of radiation transfer in plant canopies is used to predict vegetation albedos. The model is described and the results of simulations for three representative canopy types (tropical rainforest, Sonoran desert and mid-latitude deciduousforest

ecosystems. Bark water storage capacity is linked with the geoecology of temperate deciduousforests because stemflow volume and soluble inputs are partly determined by bark water storage capacity.
The aim of this study is to couple bark water storage capacity with stemflow production and solute inputs to the forest floor, thereby illustrating the importance of stemflow generation and leaching of nutrient-ions to the geoecology of forest

This study examined the distribution of Locinera maacki in a 5.2-ha old-regrowth deciduousforest in southwestern Ohio, and focused on its associations with : 1) forest-edge and internal-forest conditions; and 2) composition and structure
Méthode d'estimation du régime annuel de radiation solaire à l'intérieur d'une forêt décidue. Il est montré que l'interaction de la hauteur du soleil, de l'insolation et de la phénologie contrôlent le climat radiatif au cours de l'année. Application
Dans une forêt décidue du Tennessee, des mesures de radiation solaire au-dessus et à l'intérieur du couvert montrent l'influence du développement saisonnier du feuillage sur la diffusion radiative. Après une augmentation importante des radiations

will have destroyed the forests in 10 to 15 years if there is not a change in policy. - (SLD)
The rainfall received by a small plot of tropical deciduousforest on sand dunes in Veracruz, Mexico, was partitioned into stemflow and throughfall components to determine wether funnelling by stemflow could reduce soil leaching by transmitting
