Deforestation is one of the main reasons for the global net release of CO2 from soil to
atmosphere. Estimates of CO2 emission from soils are highly variable, mainly due to limited …

Tropical rain forests have the highest tree diversity on earth. Nonrandom spatial distributions
of these species in relation to edaphic factors could be one mechanism responsible for …

We evaluated the intention, implementation, and impact of Costa Rica's program of
payments for environmental services (PSA), which was established in the late 1990s …

Tropical montane cloud forests (TMCFs) depend on predictable, frequent, and prolonged
immersion in cloud. Clearing upwind lowland forest alters surface energy budgets in ways …

A dynamic geo-referenced land use/cover model (clue-cr) which simulates simultaneous
local, regional and national land use/cover changes in Costa Rica is presented and …

The effects of converting lowland tropical rainforest to pasture, and of subsequent
succession of pasture lands to secondary forest, were examined in the Atlantic Zone of …

Studies of forest fragmentation in the tropics have systematically paid more attention to
understanding processes contributing to the formation of landscapes that are the product of …

Terrestrial biological diversity is supported by solar energy captured by plants growing in
soil. This soil-based plant productivity also provides the foundation for human societies …

In biologically mega-diverse countries that are undergoing rapid human landscape
transformation, it is important to understand and model the patterns of land cover change …
