  • Tropical rain forests
  • Biogeography ; Ecology ; Ecosystem ; Forest ; Habitat ; Photosynthesis ; Tree species ; Tropical rain forest
  • The A. reviews the mainstream ecological literature from 1994 to 1995 to gauge the importance of ecophysiological studies in understanding the ecology of tropical rain forests.
  • Tropical rain forests
  • Biodiversity ; Biogeography ; Ecosystem ; Environmental degradation ; Forest ; Tropical rain forest
  • The A. reports on the progress in describing and explaining variation of biodiversity in tropical rain forests. He bases this review on a search of the 1997 editions of Ecology Abstracts, Ecological Abstracts and Forestry Abstracts.
  • Tropical rain forests
  • Bibliography ; Biogeography ; Deforestation ; Forest ; Global change ; Interannual variability ; Phenology ; Tropical rain forest
  • An appreciation of time on a variety of scales may help explain the complexity of tropical rain forests 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 tropical rain forest : patterns of exploitation and trade
  • Physical aspects of rain drop erosion
  • Torrential rains in central Karakoram, 9-10 September 1992 : geomorphological impacts and implications for climatic change
  • Debris flow ; Heavy rain ; Mass movement ; Monsoon ; Pakistan ; Slope
  • Descriptions of the effects of rockfalls and mudflows in the Braldu Valley, northern Pakistan, below 3000 m elevation that were triggered by the heavy rains of a late nonsoonal incursion. - (DWG)
  • Impact of acid rain on karst environments
  • Acid rain ; Chemical erosion ; England ; Karst ; Limestone ; Pollution ; Soil properties ; United Kingdom ; Weathering
  • This paper reviews recent work on the effects of acid rain on building stones and explores its likely effects on karst. The impact on natural karst weathering depends on buffering capacity of the soil.
  • Tropical rain forest : structure and dynamics
  • The main thrust of the recent publications has been in the broad area of rain forest structure (including species richness) and dynamics although there have been substantial advances also in rain forest plant ecophysiology, plant soil relation ships
  • Environmental conflicts : the case of acid rain in Europe in Environmental conflict analysis.
  • Dioxyde de soufre ; Emission de soufre ; Europe ; Géographie humaine ; Lutte contre la pollution ; Modèle RAINS ; Pluie acide ; Pollution
  • Le modèle RAINS, ou modèle de simulation et d'information sur l'acidification régionale : calcul des émissions, transferts et dépôts de soufre, transféré en acidité du sol et des lacs.
  • How much rain does a rain gage gage?
  • The characteristics of rain storms and their distribution over the Loess Plateau.
  • Rainstorms are defined as falls of over 55 mm in 24 hours with initial intensity of 0.78 mm per minute (i.e. 3.9 mm in the first 5 minutes). The distinctive features of rain storms and their spatial pattern over the Loess region are presented
  • and analysed with respect to frequency, total volume, duration, and depth of rain. (TNC).
  • Tropical rain forests
  • Bibliography ; Biogeography ; Biological indicator ; Deforestation ; Ecosystem ; Environment ; Forest ; Tropical rain forest ; Vegetation dynamics
  • Modelling erosion by rain-impacted flow
  • In this paper, an approach to modelling the sheet and interrill erosion processes dominated by rain-impacted flow is developed from the results of laboratory studies.
  • Reducing errors in rainfall estimates through rain gauge location
  • Facility location models are examined as a framework for generating rain gauge networks designed to reduce errors in mean areal precipitation.
  • Forty years of rain forest ecology 1948-1988 in perspective
  • The main fields of research in tropical rain forest ecology today are briefly described and the development of the subject over the past forty years is outlined.

  • Modern pollen-rain characteristics of tall terra firme moist evergreen forest, southern Amazonia
  • Amazon Basin ; Bolivia ; Interannual variability ; Palaeo-ecology ; Palynology ; Pollen ; Quaternary ; Spatial variation ; Taxonomy ; Tropical rain forest ; Tropical zone
  • 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.
