Dye‐sensitized Devices: Photovoltaic and Photoelectrolytic Applications
(2018-11)Dye‐sensitized approach along with stability and surface robustness in titanium dioxide (TiO2) against photocorrosion and degradation has been widely studied and applied in several important applications. This chapter ... -
DynACof: A process-based model to study growth, yield and ecosystem services of coffee agroforestry systems
(2020)The DynACof model was designed to model coffee agroforestry systems and study the trade-offs to e.g. optimize the system facing climate changes. The model simulates net primary productivity (NPP), growth, yield, mortality, ... -
Dynamical delimitation of the Central American Dry Corridor (CADC) using drought indices and aridity values
(2019)The Central American Dry Corridor (CADC) is a sub-region in the isthmus that is relatively drier than the rest of the territory. Traditional delineations of the CADC’s boundaries start at the Pacific coast of southern ... -
Dynamical downscaling of historical climate over CORDEX Central America domain with a regionally coupled atmosphere–ocean model
(2018-08)The climate in Mexico and Central America is influenced by the Pacific and the Atlantic oceanic basins and atmospheric conditions over continental North and South America. These factors and important ocean–atmosphere coupled ... -
Dynamical theory for the battery's electromotive force
(2021-03-23)We propose a dynamical theory of how the chemical energy stored in a battery generates the electromotive force (emf). In this picture, the battery's half-cell acts as an engine, cyclically extracting work from its underlying ... -
Dynamics in benthic community composition and influencing factors in an upwelling-exposed coral reef on the Pacific coast of Costa Rica
(2015-11-24)Seasonal upwelling at the northern Pacific coast of Costa Rica offers the opportunity to investigate the effects of pronounced changes in key water parameters on fine-scale dynamics of local coral reef communities. This ... -
Early diverging lineages within Cryptomycota and Chytridiomycota dominate the fungal communities in ice-covered lakes of the McMurdo Dry Valleys, Antarctica
(2017-11)Antarctic ice-covered lakes are exceptional sites for studying the ecology of aquatic fungi under conditions of minimal human disturbance. In this study, we explored the diversity and community composition of fungi in five ... -
Eastern Pacific
(2017)In the Eastern Pacific (EP) the only region where rhodolith beds have been well studied in terms of taxonomy, ecology, distribution and conservation status is the Gulf of California. Outside this region the knowledge of ... -
Eastern Pacific coastal dynamics and the Intra-Americas summer low level jet
(2005)It is generally agreed that the circulation of the Eastern Pacific off México and Central America is forced in the summer by the large-scale circulation, namely the North Equatorial Countercurrent, and in the winter by ... -
Eastern Pacific Coral Reef Provinces, Coral Community Structure and Composition: An Overview
(2017)Advances in our knowledge of eastern tropical Pacific (ETP) coral reef biogeography and ecology during the past two decades are briefly reviewed. Fifteen ETP subregions are recognized, including mainland and island localities ... -
Eavesdropping avoidance and sound propagation: the acoustic structure of soft song
(2017-12)Many species use low-amplitude (soft) song during close range interactions with conspecifics, such as in aggressive encounters or courtship displays. It has been suggested that soft song is adapted to limit eavesdropping ... -
Echinoderm diversity of a tropical estuary in the largest river basin of the Costa Rican Pacific, Eastern Tropical Pacific
(2017)Echinoderms within the Eastern Tropical Pacific have mainly been studied in association with coral reefs. Investigations on echinoderms associated with soft-bottoms and estuaries are still scarce. The present study reports ... -
Echinoderm research perspectives: A Central American bibliometric review
(2021)Introduction: Central America, a narrow strip of land dividing the Atlantic and Pacific oceans, has a high diversity of marine and terrestrial species. Echinoderms are one of the most diverse marine groups with 420 reported ... -
Echinosepala
(2020)Subtribe Pleurothallidinae is the largest and one of the most recently and intensely diversified groups in the Orchidaceae family. Estimates suggest that with a whopping 5500 species recognized today, pleurothallids represent ... -
El Eclipse total de Sol del 11 de Julio de 1991: Aspectos Generales.
(San José, CR: Editorial de la Universidad de Costa Rica, 1992)El 11 de junio de 1991 ocurrió un eclipse total de sol, el cual se pudo observar en casi todo el territorio de Costa Rica. El presente artículo explica en que consistió el fenómeno y describe las características principales ... -
Ecological and Public Health Effects of Microplastics Pollution
(2022-01)Humans and ecosystems are constantly exposed to microplastics (MP). The magnitude of contamination, their ubiquity, and high persistence over time raise serious concerns about their effects on ecosystems, wildlife, and ... -
Ecological aspects of myxomycete assemblages in two Brazilian Cerrado landscapes
(2021)We investigated the ecological aspects of the myxobiota associated with both the mesophilic and gallery forests from a fragment of the Cerrado biome located in the municipality of Anápolis, Goiás, Brazil. Myxomycete assemblages ... -
Ecological assessments of the coral reef communities in the Eastern Caribbean and the effects of herbivory in influencing coral juvenile density and algal cover
(2017)Caribbean reefs have been unevenly surveyed, with many areas lacking baseline data. In this study, the current status of Orbicella reefs, a structurally complex forereef habitat, was quantified in an understudied region, ... -
Ecological Correlates of Range Size in the Tent-Making Bat Artibeus watsoni
(2007-04)We examined variation in foraging- and roosting-range size in the tent-making bat Artibeus watsoni. We radiotracked 42 individuals at 2 sites in the Golfito Wildlife Refuge and 6 sites at Corcovado National Park, southwestern ... -
Ecological Correlates of Roost Fidelity in the Tent-Making Bat Artibeus watsoni
(2007-05)Roost switching is a common occurrence in bats, yet the causes and consequences of such behavior are poorly understood. In this study we explore the ecological correlates of roost fidelity in the tent‐making bat Artibeus ...
