This paper records sedimentary data which indicate that at least part of the Wilsons River floodplain, on the margins of the subtropical rainforest known as the Big Scrub, has a long and certainly pre-European history of relative treelessness
. Despite a general presumption that this lowland subtropical region was completely forested prior to European settlement, recent historical research has indicated that certain areas were naturally open. The data reported here, a fossil pollen record and one
Une faune décimée : celle des Vertébrés terrestres indigènes de la Réunion in Iles et tourisme en milieu tropical et subtropical.
La lutte contre les prédateurs introduits est devenue impossible, et seule la conservation des forêts primaires pourrait avoir un effet bénéfique sur la faune restante.

La forêt méditerranéenne ne disparaît pas, et ce ne sont pas les touristes qui mettent le feu. Le débroussaillement doit être un moyen, non une fin en soi. Un reboisement éventuel doit répondre à des objectifs précis. Sylviculture et élevage
In this study, rates of weathering and soil formation on granite and their dependences on acid precipitation were studied in a small forested watershed, Fengxingzhuang (FXZ), in subtropical China using geochemical mass balance equations and multiple

Sand-filled splash cups were used to study the erosivity of rainfall and throughfall in the humid subtropics of southeast China. The results showed that the splash cup measurements yielded precise and reproducible results both under open field
The book contains a review of data on basic soil types of the Transcaucasian subtropics. The originality of Transcaucasian subtropical soils permits to distinguish groups of soils of humid, semiarid and arid subtropics and to regard them in total
as a subtropical soil microcosm. The basic soils of humid subtropics (krasnozems, zheltozems, subtropical pseudopodzolic soils) are characterized in detail, as well as soils widely spread in semiarid and arid regions (cinnamonic, meadow-cinnamonic and grey
-cinnamonic soils). The problem of byelozems (gypsum-calcareous soils-pans) and black subtropical soil to be distinguished and thoroughly investigated is considered. All the data presented in this book allow to regard the subtropical soil microcosm
in the Soviet Transcaucasus as a geographic analog of some subtropical areas of the world. This book is also a valuable contribution to the general scientific theory of subtropical pedogenesis.

The vertical and horizontal distributions of light, heat and water resources in the eastern part of the subtropical region of China are studied. The vertical stratification model of agroclimatic resources was developed by taking the comprehensive
action of multiple climatic factors into account. According to the analysis of the climatic conditions for high quality and high-yield subtropical economic forest and fruit, it was proposed that subtropical economic forest and fruit production bases could
