The 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 کاملInteractions between populations of Rhizobium, Methanotrophs and Archaea in two different lowland tropical forest soil communities
Bacteria in the genus Rhizobium, methanogenic bacteria and Archaea are important in the terrestrial carbon (C) and nitrogen (N) cycle dynamics and the sequestration of C and N into the soil biomass. A better understanding of the functions of these microbial groups could provide some clarity on the impact of different land development practices and a changing climate on soil ecosystems. The comm...
متن کاملWood CO2 efflux in a primary tropical rain forest
The balance between photosynthesis and plant respiration in tropical forests may substantially affect the global carbon cycle. Woody tissue CO2 efflux is a major component of total plant respiration, but estimates of ecosystem-scale rates are uncertain because of poor sampling in the upper canopy and across landscapes. To overcome these problems, we used a portable scaffolding tower to measure ...
متن کاملLignin and enhanced litter turnover in tree plantations of lowland Costa Rica
We quantified the effect of overstory species composition on forest floor dynamics in lowland Costa Rica. Aboveground litter production and forest floor mass were measured over 1 year in 16-year-old single-species plantations established in a randomized complete block design with four blocks. The tree species investigated (=experimental treatments) were Hyeronima alchorneoides, Pentaclethra mac...
متن کاملEffect of clonal reproduction on genetic structure in Pentaclethra macroloba (Fabaceae: Mimosoideae).
The existence of monodominant forests on well-drained soils in tropical regions has been widely reported. Such forests most likely result from a combination of both ecological and evolutionary factors. Under conditions of high seed and seedling mortality, vegetative reproduction could create a reproductive advantage leading to forest dominance, and profoundly affect the distribution of genetic ...
