Carbon accumulation in aboveground and belowground biomass and soil of different age native forest plantations in the humid tropical lowlands of Costa Rica
(Universidad Nacional, Costa Rica, 2012)Generic or default values to account for biomass and carbon accumulation in tropical forest ecosystems are generally recognized as a major source of errors, making site and species specific data the best way to achieve ... -
Carbon accumulation in the biomass and soil of different aged secondary forests in the humid tropics of Costa Rica
(Elsevier, 2011-10-15)Efforts are needed in order to increase confidence for carbon accounts in the land use sector, especially in tropical forest ecosystems that often need to turn to default values given the lack of precise and reliable site ... -
Chemical characterization of filterable PM2.5 emissions generated from regulated stationary sources in the Metropolitan Area of Costa Rica
(Elsevier, 2017-01-14)Filterable PM2.5 concentrations and their chemical characterizations were analyzed for 67 boilers and 25 indirect furnaces located in the Metropolitan Area of Costa Rica from February 2014 to November 2015. The PM2.5 samples ... -
Climatic and edaphic controls over tropical forest diversity and vegetation carbon storage
(Springer Nature, 2020-03-19)Tropical rainforests harbor exceptionally high biodiversity and store large amounts of carbon in vegetation biomass. However, regional variation in plant species richness and vegetation carbon stock can be substantial, and ... -
Determination of carbonyls and their sources in three sites of the metropolitan area of Costa Rica, Central America
(Springer Science+Business Media B.V, 2011-03-02)Ambient levels of carbonyl compounds and their possible sources were studied at three places in the metropolitan area of Costa Rica, including a residential, an industrial, and a com mercial downtown area with high ... -
Estimación de la biomasa y carbono almacenado en un bosque primario intervenido de la zona protectora "El Rodeo", Costa Rica
(Universidad de Pinar del Río "Hermanos Saíz Montes de Oca", Cuba, 2019-09-01)En la Estrategia Nacional de Cambio Climático de Costa Rica se recalcó la importancia de los ecosistemas boscosos en la absorción y fijación de CO2, como un mecanismo para lograr la carbono-neutralidad. Esta investigación ... -
Medición de la huella de carbono del año 2016 y diseño de medidas para lograr la carbono neutralidad en la Asamblea Legislativa de Costa Rica
(Universidad Nacional, Costa Rica, 2020-10)El presente trabajo consistió en elaborar un inventario de emisiones de gases efecto invernadero para 13 edificios, entre propios y alquilados, de la Asamblea Legislativa de Costa Rica en 2016. Además, se desarrolló un ... -
Stock de carbono en el bosque natural y en sitios de regeneración asistida en la Estación Biológica Osa Verde y su aporte a la mitigación del cambio climático
(Universidad Nacional, Costa Rica, 2022-08)Los bosques desempeñan un papel importante en el ciclo del carbono, al presentar degradación estos desfavorecen la capacidad para almacenar carbono en la vegetación y aumentan las emisiones. Esta investigación tuvo como ... -
Temporal and spatial variations in organic and elemental carbon concentrations in PM10/PM2.5 in the metropolitan area of Costa Rica, Central America
(Science Direct, 2013-01)PM2.5 and PM10 samples were collected at 4 and 14 sampling sites, respectively, located in the Metropolitan area of Costa Rica (MACR), during 2010-2011. These sites were representative of commercial, industrial and residential ... -
The life cycle carbon balance of selective logging in tropical forests of Costa Rica
(Wiley Periodicals, 2020-06-01)The effect of logging on atmospheric carbon concentrations remains highly contested, especially in the tropics where it is associated to forest degradation. To contribute to this discussion, we estimated the carbon balance ... -
Valores de referencia de biomasa aérea para la vegetación arbórea urbana y periurbana, Heredia, Costa Rica
(Universidad Nacional, Costa Rica, 2022)Los árboles cumplen un papel fundamental en la mejora de la calidad de vida de los habitantes en las ciudades y entre sus funciones más relevantes ayudan a la mitigación de los efectos del cambio cli- mático actuando en ...
