microenvironmental changes in the forest floor are responsible positive effect of the death of bamboos in the regeneration of oak.
In temperate and subtropical forests around the world, the rare blooming of bamboo species (species called Quila or Colihue) is an event that may have not yet understood consequences for plant regeneration. Giordano and colleagues studied seed germination and growth of understory species after a massive event bamboo flowering ( Quila, Chusquea culeou ) in a temperate forest of Argentina Patagonia (Lanin National Park). Examined the possible effect of changes in microhabitat product mass death of C. culeou , and found that the death of C. culeou generates a window of opportunity for germination and growth of understory plants. Particularly the germination of Nothofagus oblique (Roble, Nothofagaceae) was facilitated by this event flowering. Changes in light quality and amplitude of the fluctuations temperatures in the forest floor are responsible for a positive response in the regeneration of oak. This adds new information on the mechanisms of regeneration in forest where the occurrence of bamboo and its persistence for many years is important.
