Impact of land use on Costa Rican tropical montane cloud forests: Sensitivity of cumulus cloud field characteristics to lowland deforestation
[1] Recent studies have shown that there has been a reduction in dry season moisture input from direct interception of cloud water and wind-blown mist at the lee edge of the Monteverde cloud forest, Costa Rica, since the mid 1970s. This reduction of moisture could be responsible for the population crashes of anurans observed in the region. It has been hypothesized that this behavior is a result...
متن کاملThe impact of Pentaclethra macroloba on soil microbial nitrogen fixing communities and nutrients within developing secondary forests in the Northern Zone of Costa Rica
In the current study, we showed that Pentaclethra macroloba appears to influence the microbial communities within the soil of secondary forests in the Northern Zone of Costa Rica. The soil closest to the Pentaclethra macroloba trees (“tree soil”) had a lower abundance of the N-fixing bacteria Frankia, but greater amounts of both nifH gene and Rhizobium than soils furthest away (“forest soils”)....
متن کاملDeforestation Spillovers from Costa Rican Protected Areas
Resumen Spillovers can significantly reduce or enhance the effects of land-use policies, yet there exists little rigorous evidence concerning their magnitudes. We examine how national parks within Costa Rica affect the clearing of forest nearby. We find that average deforestation spillover impacts are not significant within 0-5km and 5-10km rings around parks. However, we argue that this averag...
متن کاملClimate and soil drive forest structure in Bolivian lowland forests
Climate is one of the most important factors determining variation in forest structure, but whether soils have independent effects is less clear. We evaluate how climate and soil independently affect forest structure, using 89 200 stems ≥ 10 cm dbh from 220 1-ha permanent plots distributed along environmental gradients in lowland Bolivia. Fifteen forest structural variables, related to vertical...
متن کاملVariation in leaf litter nutrients of a Costa Rican rain forest is related to precipitation
By assessing current leaf litter nutrient dynamics, we may be able to predict responses of nutrient cycling in tropical ecosystems to future environmental change. The goal of this study was to assess whether nutrient cycling is related to seasonal variation in rainfall in a wet tropical forest. We examined leaf litter of an old-growth tropical rain forest in N.E. Costa Rica over a 4-year period...
