PHOTOSYNTHETIC LIGHT ENVIRONMENTS IN A LOWLAND TROPICAL RAIN FOREST IN COSTA RICA
TLDR
The clearing exhibited the greatest diurnal variations in PPFD and the least day-to-day variation, whereas the understorey exhibited the least diurnal variation and the greatest day- to-day variations.
Photosynthetic Responses of Tropical Forest Plants to Contrasting Light Environments
Across the complex matrix of microsites that compose tropical forests, light availability varies more dramatically than any other single plant resource. On a sunny day, instantaneous measurements of
ECOSYSTEM DEVELOPMENT AND PLANT SUCCESSION ON LANDSLIDES IN THE CARIBBEAN
Landslides are common in mountainous regions of the Caribbean and are triggered by heavy rains and earthquakes, and often occur in association with human disturbances (e.g., roads). Spatially
Changes in Light Availability Following Hurricane Hugo in a Subtropical Montane Forest in Puerto Rico
TLDR
The changes in light availability in the understory of a subtropical wet forest (Luquillo Experimental Forest, Puerto Rico) were monitored after the passage of Hurricane Hugo to discern patterns of autocorrelation in total daily PPFD along the transect.
Vegetation effects on microclimate in lowland tropical forest in Costa Rica
The temperature and atmospheric humidity in a tropical lowland rain forest in Costa Rica were measured in order to assess the microclimate in different forest environments. Two disturbed sites, a
Nitrogen immobilization by decomposing woody debris and the recovery of tropical wet forest from hurricane disturbance
TLDR
It is suggested that the manner in which woody debris regulates ecosystem function in different forests is significantly affected by disturbance regime, as well as the substantial influence that Woody debris has upon nutrient cycling and productivity in forest ecosystems through its effects on the activity of decomposers.
Productivity and Nutrient Cycling of Alaskan Tundra: Enhancement by Flowing Soil Water
Patterns of biomass, productivity, and nutrient cycling were compared be- tween water-track and nontrack areas in Alaskan tussock tundra. Water tracks (channels of subsurface water drainage) sampled
Effect of CO2‐enrichnient on seedling physiology and growth of two tropical tree species
TLDR
Seedlings of two tree species from the Atlantic lowlands of Costa Rica, Ochroma la-gopus Swartz, a fast-growing pioneer species, and Pentaclethra macroloba (Willd.) Kuntze, a slower-growing climax species, were grown under enriched atmospheric CO2 in controlled environment chambers resulting in significant increases in water use efficiency.
Light Environments of Tropical Forests
Measurements of photosynthetically active radiation (PAR) in tropical forests are reviewed and discussed. Many studies of the light environment in tropical forests have emphasized the importance of
Home site advantage in two long‐lived arctic plant species: results from two 30‐year reciprocal transplant studies
TLDR
Reciprocal transplant experiments designed to quantify genetic and environmental effects on phenotype are powerful tools for the study of local adaptation but the cumulative effects of many years in novel environments may be required for fitness differences and phenotypic changes to accrue.
