IAI-Data-CRN_012_Marchesini_Water: Gravimetric soil water content during the massive flowering and death of the bamboo Chusquea culeou

During 2001 a native forest in the South of Argentina experienced the massive flowering and death of the bamboo Chusquea culeou, a dominant understory species. We proposed to assess the impact of this event on: a) the environmental factors and b) the population dynamics of forest vegetation. We recorded air and soil temperature, relative air humidity and light intensity under two conditions: death and green bamboo. We also registered the survirvoship, growth and herbivory rates on Nothofagus nervosa, a canopy dominant tree and Chusquea culeou seedlings. In field we collected soil cores samples using pvc tubes of 5 cm diameter at 5 cm of deph from several sites with green and death vegetation. In laboratory we placed a subsample of soil in a drying oven at 105bC for 48 hs for determination of gravimetric soil water content.
