Abstract:: The growth of Alnus acuminata (HBK) 0. Ktze, Cupressus lusitanica Mill., Gmelina arborea Roxb, Pinus caribaea var. hondurensis Barr. & Golf., and Tectona grandis L. in Costa Rica and twenty seven soil and climatic factors were analyzed to determine the relationship between major environmental factors and growth rates of these...

Creator:: Helmer, Eileen Hoey
Abstract:: Previous difficulties mapping tropical forest successional stage with satellite imagery may be one of the reasons why little is known about what socioeconomic and biophysical factors control tropical secondary forest pattern over landscapes. Additional remote sensing challenges occur in regions with steep topography, because the spectral responses of land covers...

Creator:: Hadley, Adam S.
Abstract:: A growing body of work reveals that animal-mediated pollination is negatively affected by anthropogenic disturbance. Landscape-scale disturbance results in two often inter-related processes: (1) habitat loss, and (2) disruptions of habitat configuration (i.e. fragmentation). Understanding the relative effects of such processes is critical in designing effective management strategies to limit...

Creator:: Cifuentes Jara, Miguel
Abstract:: Carbon sequestration in tropical secondary forests growing in all climates must be quantified to understand their potential role in adaptation and mitigation strategies of global climate change. Total aboveground biomass (TAGB), soil carbon, and total ecosystem carbon (TEC) were measured in 54 secondary forests growing along a broad bioclimatic gradient...

Creator:: Matteson, Robyn S.
Abstract:: At the Costa Rica Dome (CRD), upwelling associated with cyclonic circulation and the presence of a shallow thermocline support a highly productive biological habitat, exploited by marine fauna at several trophic levels. During January 2008, a cruise to the CRD by the R/V Pacific Storm was conducted to relocate blue...

Creator:: Hesson, Kevin M.
Abstract:: Landscape positions have been used to determine soil properties. My soil study in Monteverde on the Pacific slope of Costa Rica was designed to examine soil-landscape relationships for sites with various land use histories and management. Soil pits were dug at Nacimiento y Vida, Crandell, Curi-cancha, La Calandria, and Finca...
