Abstrac As a pilot study potential biophysical and human land use drivers in Costa Rica were evaluated using multi-variate statistical methods in a nested scale analysis. The reconstructed land use drivers and their quantified effects on land use were applied within a dynamic framework CLUE (Conversion of Land Use and its Effects) to model land use dynamics in Costa Rica from 1973 to 1984. Our pilot study demonstrates that a land use/cover system can be described as a scale-dependent hierarchical system and that its dynamics can be satisfactorily modelled as functions of biophysical and human drivers.

Soluble reactive phosphorus (SRP) transport/retention was determined in two rain forest streams (Salto, Pantano) draining La Selva Biological Station, Costa Rica. There, SRP levels can be naturally high due to groundwater enriched by geothermal activity within the surfically dormant volcanic landscape, and subsequently discharged at ambient temperature. Combined field and laboratory approaches simulated high but natural geothermal SRP input with the objective of estimating the magnitude of amended SRP retention within high and low SRP settings and determining the underlying mechanisms of SRP retention. First, we examined short-term SRP retention/transport using combined SRP-conservative tracer additions at high...

Nutrient recycling by animals is a potentially important biogeochemical process in both terrestrial and aquatic ecosystems. Stoichiometric traits of individual species may result in some taxa playing disproportionately important roles in the recycling of nutrients relative to their biomass, acting as keystone nutrient recyclers. We examined factors controlling the relative contribution of 12 Neotropical fish species to nutrient recycling in four streams spanning a range of phosphorus (P) levels. In high-P conditions (135 μg/L soluble reactive phosphorus, SRP), most species fed on P-enriched diets and P excretion rates were high across species. In low-P conditions (3 μg/L SRP), aquatic food resources were depleted...

This inventory was originally created by Marc and others (2016) describing the landslides triggered by the M 7.6 Valle de la Estrella, Costa Rica earthquake, also known as the Limon earthquake, that occurred on 22 April 1991 at 21:56:51 UTC. Care should be taken when comparing with other inventories because different authors use different mapping techniques. This inventory also could be associated with other earthquakes such as aftershocks or triggered events. Please check the author methods summary and the original data source for more information on these details and to confirm the viability of this inventory for your specific use. With the exception of the data from USGS sources, the inventory data and associated...

This dataset presents information about facilities relating to the mineral industries of Latin America and the Caribbean. Facilities include mines, mineral processing plants (including refineries and smelters), oil and gas field locations, and petroleum refineries. Relevant data fields include the mineral commodity, specific forms of the mineral commodity produced, location information, facility name, operator, ownership of the facility, annual production capacity, operational status, as well as geographic coordinates and locational accuracy. These data are derived from data presented by country by the Global Minerals Analysis section of the U.S. Geological Survey's (USGS) National Minerals Information Center (NMIC)...
