Carbon Storage in Cold Temperate Ecosystems in Southern Patagonia, Argentina.
(inTech, 2011-08)Recently there has been an increasing interest of research related to improve the understanding of carbon (C) sequestration mainly under Article 3.4 of the Kyoto Protocol of the United Nations Framework Convention on Climate ... -
Putting plant resistance traits on the map: a test of the idea that plants are better defended at lower latitudes
(Wiley, 2011-05-03)It has long been believed that plant species from the tropics have higher levels of traits associated with resistance to herbivores than do species from higher latitudes. A meta-analysis recently showed that the published ... -
Foliar N⁄ P ratio and nutrient limitation to vegetation growth on Keerqin sandy grassland of North-east China.
(Wiley, 2011-02-01)To examine whether the critical leaf N ⁄ P ratios (of 14, 16) are valid to test nutrient limitation in the context of semi-arid sandy grasslands, an experiment was conducted on a Keerqin sandy grassland in North-east China ... -
Do light and alfalfa responses to cloth and slatted shade represent those measured under an agroforestry system?
(Springer Nature, 2011-02)Shade cloth is commonly used in agroforestry research. It produces a continuous, uniform reduced light environment. Shade cloth and a slatted structure were compared in relation to the inability to represent the light ... -
Canopy structure analysis for estimating forest regeneration dynamics and growth in Nothofagus pumilio forests
(Springer, 2011-04-08)Introduction Silviculture systems applied in Nothofagus pumilio forests are based on opening the canopy to stimulate natural regeneration by modifying light and soil moisture. The objective is to evaluate regeneration ... -
