Stability of tropical forest tree carbon‐water relations in a rainfall exclusion treatment through shifts in effective water uptake depth

Rainfall exclusion in an eastern Amazonian forest alters soil water movement and depth of water uptake.

Deuterium-labeled water was used to study the effect of the Tapajós Throughfall Exclusion Experiment (TTEE) on soil moisture movement and on depth of water uptake by trees of Coussarea racemosa, Sclerolobium chrysophyllum, and Eschweilera pedicellata. The TTEE simulates an extended dry season in an eastern Amazonian rainforest, a plausible scenario if the El Niño phenomenon changes with climate...

Bio-indicators in the tropical forest of Western Ghats environment

Background: Investigation on the natural radionuclides 238U, 232Th, 40K and natural fallout radionuclide 210Po in the prominent plants species of Western Ghats tropical forest near Kotagiri have been carried out as a part of baseline background radiation studies in the forest environment. Materials and Methods: The prominent plants species of the region Evodia roxburghiana and Eleaoca...

Patterns of Tree Mortality in a Monodominant Tropical Forest

Drivers of tree species distribution across a tropical rainfall gradient

Understanding the factors shaping species distribution patterns along tropical rainfall gradients is necessary to predict the consequences of climate change for tropical tree communities. Direct effects of water availability exclude wet forest species from dry forests, but the exclusion of dry forest species from wet forests remains unexplained. We tested the hypothesis that high light and nutr...

Effective Factors on the Stability of Oil-in-Water Emulsion Based Beverage: A Review

Beverage emulsions are systems that are composed of two liquids including oil and water which are prepared by homogenizing oil phase in an acidic aqueous phase. They must be stable in both concentrated and diluted form for a period of 6-12 months upon standing at room temperature. Two immiscible phases contained systems are thermodynamically unsta-ble. In other words, they are vulnerable to bre...
