Persistent tremor within the northern Costa Rica seismogenic zone

Geodetic and seismic constraints on some seismogenic zone processes in Costa Rica

[1] New seismic and geodetic data from Costa Rica provide insight into seismogenic zone processes in Central America, where the Cocos and Caribbean plates converge. Seismic data are from combined land and ocean bottom deployments in the Nicoya peninsula in northern Costa Rica and near the Osa peninsula in southern Costa Rica. In Nicoya, inversion of GPS data suggests two locked patches centered...

The Effects of the N-Fixing Tree Pentaclethra macroloba on the Above and Below Ground Communities Within a Primary Forest in the Northern Zone of Costa Rica

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”)....

The dystrophinopathies in Costa Rica.

A five-years long study aiming to describe the basic genetic epidemiology of the dystrophinopathies in Costa Rica recruited 31 patients with clinical symptoms of DMD/BMD at the National Children's Hospital (HNN). This center is the obligate reference hospital of the national health system for genetic diseases, however, the geographic origin of the patients, a low percentage of deletions and a h...
