Changes in the ratio of twig to foliage in litterfall with species composition, and consequences for decomposition across a long term chronosequence

Article Abstract:

The tree litterfall and the litter decomposition for several boreal forested zones are studied to understand the changes in the ratio of twig to foliar litterfall with the composition of the species. The analysis proves that the reduction in the decomposition rates in boreal forest soils can be completely attributed to the increase in the twig population in total litterfall, in the absence of fire and presence of a long term chronosequence in such places.

Conservation and development in Amazonian extractive reserves: The case of Alto Jurua

Article Abstract:

A detailed analysis of deforestation and demographic and socioeconomic changes in Alto Jurua, the first extractive reserve created in Brazil in 1990 is presented. It is concluded that the Reserve represents a very dynamic setting with positive conservation and development outcomes during its first decade.
