The A. reviews the mainstream ecological literature from 1994 to 1995 to gauge the importance of ecophysiological studies in understanding the ecology of tropical rainforests.
The A. reports on the progress in describing and explaining variation of biodiversity in tropical rainforests. He bases this review on a search of the 1997 editions of Ecology Abstracts, Ecological Abstracts and Forestry Abstracts.
An appreciation of time on a variety of scales may help explain the complexity of tropical rainforests and provide a frame of reference to consider the consequences of anthropogenic deforestation and global climatic change on this biome. Here
the A. reviews published tropical rain-forest research that has focused on the time dimension from late 1992 until early 1994.
The A. briefly reviews major themes in published tropical forest research between 1991 and 1992 inclusive in an attempt to identify what questions are believed to be important.
The main thrust of the recent publications has been in the broad area of rainforest structure (including species richness) and dynamics although there have been substantial advances also in rainforest plant ecophysiology, plant soil relation ships
Forty years of rainforest ecology 1948-1988 in perspective
The main fields of research in tropical rainforest ecology today are briefly described and the development of the subject over the past forty years is outlined.
The following review (1987-1989) covers seven areas of study : microclimate, climate and vegetation change| hydrology| mineral nutrition| forest structure| forest regeneration| herbivory| conservation.
Geomorphological studies on the Late Quaternary landscape evolution in areas of eastern Zaire indicated by pedological, sedimentological, and geochemical evidence that the recent rainforest of the region within the glacial core-areas was strongly
Tropical rainforest and climate dynamics of the Atlantic lowland, southern Brazil, during the late Quaternary

The AA. present results of an investigation into past vegetation and climate in the southern Atlantic rainforest region, using pollen and radiocarbon analysises of recently discovered late Pleistocene deposits at Volta Velha, Santa Catarina, Brazil.
Here, the AA. present the first modern pollen-rain data for tall terra firme moist evergreen Amazon forest, collected between 1999 and 2001 from artificial pollen traps in Noel Kempff Mercado National Park (NE Bolivia). Spearman's rank correlations
were performed to assess the extent of spatial and inter-annual variability in the pollen rain, whilst statistically distinctive data were identified using Principal Components Analysis (PCA). Comparisons which the floristic and basal area data
of the plot enabled the degree to which taxa are over/under-represented in the pollen rain to be assessed.
Effect of fire on soil, rice, weeds and forest regrowth in a rainforest zone (Côte d'Ivoire)

Forest, soil, rice, weeds and regrowth were studied in the fields off local farmers in permanent plots during 2-5 years. The fields covered all currently cultivated soil types and forest types. This study is concerned with the full shifting
