The following review (1987-1989) covers seven areas of study : microclimate, climate and vegetation change| hydrology| mineral nutrition| forest structure| forest regeneration| herbivory| conservation.
The rainfall received by a small plot of tropical deciduous forest 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
Using a forest stand simulation model to examine the ecological and climatic significance of the Late-Quaternary pine-spruce pollen zone in Eastern Virginia, U.S.A.
A simulation model of forest dynamics was used to reconstruct the composition and structure of the forests on the Delmarva Peninsula of Virginia, where pollen data were available to test the model, and climate and soils data were available to drive
The spring in the forest terrain at Svartberget, Northern Sweden
The aim of this study is to illustrate differences between three forest sites with respect to the relationship between the snow cover and the air and soil temperature. During nine years (1980-88) observations have been carried out about
this relationship on three points. Two of the points lie on a glacial till slope, one in an old spruce forest and the other in a clear felled area. The third point lies on a clear felled area on level sediment. This study mainly deals with the period when the soils
The Maraca Rainforest Project. II. Soil hydrology, nutrient and erosional response to the clearance of terra firme forest, Maraca Island, Roraima, northern Brazil
Results and discussion of the experiment carried out on the Ilha de Maraca, to investigate the effects of partial and complete clearance of forest plots on subsurface soil moisture content, tension and water fluxes, overland flow, the production
The AA. examine the hypothesis that soil chemical properties other than nitrogen supply partly explain the altitudinal changes in the rain forest. They also compare the soils on Volcan Barva with those on several other tropical mountains to see
if differences in soil chemistry are likely to be the cause of differences in forest structure between mountains.
In the Atlantic Coastal Forest Biome of eastern Bahia, the piassava palm (Attalea funifera) inhabits coastal podzolic soils but not nearby latosols. This paper examines the role of changing edaphic conditions and access to sunlight
The AA. interpret the biotic record to record a phase in the transition from closed boreal forest to open tundra as climatic conditions deteriorated in advance of continental glaciation.
The purpose of this study is to study the processes, both active and inactive, which influence the formation, structure and distribution of subalpine heaths in the Abisko Valley and to compare their ecotope with the adjacent birch forest.
Bald cypress (Taxodium distichum) regeneration is examined in the bottomland forest of the lower Hatchie River in western Tennessee. Bald cypress is found mostly in abandoned meanders. Its absence along the active channel indicates that colonization
, rates of sediment supply, and the rate of sea-level rise. The stratigraphy and chronology of Holocene deposits on mangrove shorelines allow reconstruction of the way that mangrove forests have responded to rising sea level in the past, and thus provide
Studies of the ground temperatures and hydrological conditions at four sites on a subalpine heath and in the birch forest in the subarctic valley in Abisko from 1984-87 show that a clear relationship exists between ground temperature and climatic
