Presence of microplastics in six bivalve species (Mollusca, Bivalvia) commercially exploited at the Pacific coast of Costa Rica, Central America
(2022-08)
Microplastic pollution represents a serious threat to coastal marine systems. We evaluated the presence of microplastics (MPs) in 168 specimens of six commercially exploited bivalve species in the Golfo de Nicoya, Costa ...
Rapid shift in microbial community structure in a neutral hydrothermal hot spring from Costa Rica
(2020)
In this work, we characterize the geochemistry and microbial community of Bajo las Peñas, a neutral (pH 6.5-7.4), hot spring (T = 62.0-68.0°C) located near Turrialba Volcano, Costa Rica. The microbiota at its two sources ...
Relaciones hídricas en árboles del bosque tropical seco: el caso de Enterolobium cyclocarpum
(2011)
Las relaciones hídricas en árboles de Enterolobium cyclocarpum del Parque Nacional Santa Rosa, Costa Rica,
se estudiaron en diferentes momentos del curso diurno y a lo largo de dos ciclos fenológicos. La característica ...
C1 compounds shape the microbial community of an abandoned century-old oil exploration well
(2020)
The search for microorganisms that degrade hydrocarbons is highly relevant because it enables the bioremediation of these substances cheaply and without dangerous by-products. In this work, we studied the microbial communities ...
Richness of cultivable endophytic fungi along an altitudinal gradient in wet forests of Costa Rica
(2016-04)
We collected various plant species along an altitudinal gradient ranging from 400 to 2900 m in tropical wet forests of Costa Rica, isolated the associated endophytic fungi, and performed bioinformatic analyses to determine ...
Microplastic ingestion by a herring Opisthonema sp. in the Pacific coast of Costa Rica
(2020-07)
Current knowledge of the presence of microplastics (MP) in marine species in tropical areas is still limited. The presence of MP was examined in the gastrointestinal content of 30 filter feeders of the herring Opisthonema ...
Resistencia a desinfectantes y su relación con la resistencia a los antibióticos
Resistance to disinfectants and their relationship with antibiotic resistance
(2020)
Objetivo: sistematizar los principales mecanismos de acción de los desinfectantes y describir mecanismos de resistencia comunes entre biocidas y antibióticos. Métodos: se realizó una revisión bibliográfica de artículos ...
Microbial Community Structure Alogn a Horizontal Oxygen Gradient in a Costa Rican Volcanic Influeced Acid Rock Drainage System
(2020-06-22)
We describe the geochemistry and microbial diversity of a pristine environment that resembles an acid rock drainage (ARD) but it is actually the result of hydrothermal and volcanic influences. We designate this environment, ...
Methylotrophs and Hydrocarbon-Degrading Bacteria Are Key Players in the Microbial Community of an Abandoned Century-Old Oil Exploration Well
(2021-04-17)
In this work, we studied the microbial community and the physicochemical conditions prevailing in an exploratory oil well, abandoned a century ago, located in the Cahuita National Park (Costa Rica). According to our analysis, ...
Dry-season leaf flushing of Enterolobium cyclocarpum (ear-pod tree): above- and belowground phenology and water relations
(2007-11)
Above- and belowground phenology and water relations of Enterolobium cyclocarpum Jacq. trees in the dry
forest of Santa Rosa National Park, Costa Rica were studied during two consecutive phenological cycles, from November ...
