Assessing the reactive surface area of soils and the association of soil organic carbon with natural oxide nanoparticles using ferrihydrite as proxy
(2020-09-09)Assessment of the surface reactivity of natural metal-(hydr)oxide nanoparticles is necessary for predicting ion adsorption phenomena in soils using surface complexation modeling. Here, we describe how the equilibrium ... -
Assessment of Central America Regional Climate Outlook Forum maps, 1998-2013
(2016)Starting 1997, the Regional Climate Outlook Forums or RCOFs have taken place in different Latin American countries, as an effort to generate climatic prediction products. “since 2000, the Forum is organized in Central ... -

Assessment of the Spatial Variation in the Occurrence and Intensity of Major Hurricanes in the Western Hemisphere
(2023-01-04)Major hurricanes are a critical hazard for North and Central America. The present study investigated the trends of occurrence, affectation, and intensity of major hurricanes in the North Atlantic and Northeast Pacific ... -
Association between rainfall seasonality and the flowering of epiphytic plants in a Neotropical montane forest
(2017)The association between the reproductive phenology of epiphytic communities with environmental and ecological factors remains largely unexplored. Because epiphytes depend on environmental moisture, seasonal changes in ... -
Associations of decadal to multidecadal sea-surface temperature variability with Upper Colorado River flow
(2007-02)The relations of decadal to multidecadal (D2M) variability in global sea-surface temperatures (SSTs) with D2M variability in the flow of the Upper Colorado River Basin (UCRB) are examined for the years 1906- 2003. Results ... -
Associations of multi-decadal sea-surface temperature variability with US drought
(2008-09)Recent research suggests a link between drought occurrence in the conterminous United States (US) and sea surface temperature (SST) variability in both the tropical Pacific and North Atlantic Oceans on decadal to multidecadal ... -
Asymptotic expansion of the invariant measure for ballistic random walk in the low disorder regime
(2015)We consider a random walk in random environment in the low disorder regime on Zd. That is, the probability that the random walk jumps from a site x to a nearest neighboring site x+e is given by p(e)+ǫξ(x,e), where p(e) is ... -
Atenuación de contaminantes por procesos de sorción en la zona no saturada, en una parcela experimental en el occidente del Valle Central de Costa Rica
(2017-05)Se realizó un estudio sobre la atenuación de contaminantes con el propósito de determinar las constantes de reparto entre el suelo y el agua intersticial para una decena de plaguicidas. Las muestras de suelo fueron ... -
Atmospheric circulation types controlling rainfall in the Central American Isthmus
(2022)Rainfall mechanisms in the Central American Isthmus are controlled by complex physical interactions across spatial and temporal scales, which are reflected on the dynamics of atmospheric circulation patterns affecting ... -
Atmospheric forcing of cool subsurface water events in Bahía Culebra, Gulf of Papagayo, Costa Rica
(Revista Biología Tropical, 60 (2): 173-186, 2012-04)Bahía Culebra, at Gulf of Papagayo on the north Pacific coast of Costa Rica, is an area of seasonal upwelling where more intense cooling events may occur during some boreal winter weeks mainly. To study these extreme cool ... -
Atmospheric forcing of the eastern tropical Pacific: A review
(2006-06-06)The increase in marine, land surface, atmospheric and satellite data during recent decades has led to an improved understanding of the air–sea interaction processes in the eastern tropical Pacific. This is also thanks to ... -
Attribution of Declining Western U.S. Snowpack to Human Effects
(2008-12-01)Observations show snowpack has declined across much of the western United States over the period 1950–99. This reduction has important social and economic implications, as water retained in the snowpack from winter storms ... -
Austinotheres angelicus (Lockington, 1877): the correct name for the symbiotic crab Juxtafabia muliniarum sensu Cabrera-Peña et al. (2001) (Crustacea, Brachyura, Pinnotheridae)
