Increased human activities on sandy beaches have significantly impacted ecosystems. This study aims to determine whether beaches with higher tourism and human activities exhibit greater impact on various ecological indicators compared to less-visited beaches. Ecological monitoring was performed across three sandy beaches, where sand samples were co...
Freshwater environments and coastal marine areas provide key ecosystem services to society and serve as habitats for biodiversity. However, they face major challenges from human activities and climate factors, leading to global degradation. The effect of these agents depends on geographic location and climate, among other factors. To comprehensivel...
El lanzamiento de la Década de los Océanos en el año 2017 estableció nuevas visiones entre la ciencia y política, para fortalecer la investigación y la gestión de los océanos y las costas. Con un 92% de superficie marina, Costa Rica es una nación de mar, que posee una gran diversidad marina, y que realiza esfuerzos para conocer mejor sus recursos c...
Introducción: El crecimiento socioeconómico ha causado presión sobre los ecosistemas marinos, y existe poca información que pueda ser utilizada para el manejo de playas en Nicoya, Costa Rica. Objetivo: Determinar la calidad fisicoquímica y microbiológica del agua marino-costera en Nicoya, Costa Rica. Métodos: En octubre de 2021, y mayo y junio de 2...
RESUMEN. Introducción: La microcuenca del río Durazno en Costa Rica es fuente de agua para consumo humano, pero se sospecha de contaminación microbiológica por varios usos del suelo. Objetivo: Evaluar la calidad del agua de la microcuenca del Durazno desde el punto de vista fisicoquímico, microbiológico y antibiótico. Métodos: Utilizamos el índice...
Prokaryotic diversity in lakes has been studied for many years mainly focusing on community structure and how the bacterial assemblages are driven by physicochemical conditions such as temperature, oxygen, and nutrients. However, little is known about how the composition and function of the prokaryotic community changes upon lake stratification. To...
Coastal waters are a major source of marine methane to the atmosphere. Particularly high concentrations of this potent greenhouse gas are found in anoxic waters, but it remains unclear if and to what extent anaerobic methanotrophs mitigate the methane flux. Here we investigate the long‐term dynamics in methanotrophic activity and the methanotroph c...
This study was a baseline with quantitative data of marine litter along the Gulf of Nicoya, Costa Rica. The objective of the study was to quantify marine litter and its association with human activities in this estuarine gulf. A total of fourteen sandy beaches were cataloged by the degree of urbanization, tourism intensity, beach cleaning programs,...
We measured water temperature, salinity, Secchi, and concentrations of dissolved oxygen, chlorophyll, suspended matter, and nutrients in the water column at six sites at Cahuita National Park on the southern Caribbean coast of Costa Rica, at three-month intervals over a two-year time period in 2017 and 2018. We also assemble and compare the availab...
Tropical estuaries are very little studied compared to temperate ones, despite their generally high primary production rate and hence potential contribution to global carbon and nitrogen budgets. The Gulf of Nicoya (northwest Costa Rica Pacific coast) is one of the most productive estuaries worldwide. However, how changes in benthopelagic coupling...
Primary production of microphytobenthos (MPB) contributes significantly to the total production in shallow coastal environments. MPB is a diverse community in which diatoms are usually the main microalgal group. Diatoms require N, P and other nutrients as with other autotrophs, but in addition require silicate to create their outer cell wall. There...
The availability of baseline data on water parameters and primary productivity is essential in comparative studies aimed at identifying environmental trends, like eutrophication, in coastal embayments. In this context, the objetive of this work is to make accessible data, collected from 2000 to 2002, on 13 water parameters (Secchi depth, temperatur...
Bacteria of the NC10 phylum link anaerobic methane oxidation to nitrite denitrification through a unique O2-producing intra-aerobic methanotrophy pathway. A niche for NC10 in the pelagic ocean has not been confirmed. We show that NC10 bacteria are present and transcriptionally active in oceanic oxygen minimum zones (OMZs) off northern Mexico and Co...
La llegada de contaminantes a los ecosistemas costeros es un problema global en aumento. Los datos sobre contaminación por metales en sitios tropicales son escasos y se necesitan con urgencia estudios para proveer un marco de referencia y estimar el impacto relativo de estos y otros contaminantes. El objetivo de este trabajo fue hacer accesible los...
Primary productivity in the National Térraba-Sierpe Wetland, Costa Rica. Phytoplankton primary production (PP) was determined in a broad sector of the Térraba-Sierpe National Wetland, Costa Rica, from September to November 2008 in the rainy season and from January to March 2009 in the dry season. Six sampling stations were located at the Northern a...
Oceanographic features of Golfo Dulce, Costa Rican Pacific: a review for decision-making in marine conservation. From September 2005 to November 2007 we studied the meteorological typologies and the physical, chemical and zooplankton oceanography of Golfo Dulce, a unique aquatic ecosystem in the South Pacific of Costa Rica. The water circulation pa...
Phytoplankton primary production (PP) was determined in a broad sector of the Térraba-Sierpe National Wetland, Costa Rica, from September to November 2008 in the rainy season and from January to March 2009 in the dry season. Six sampling stations were located at the Northern and Central zone of the wetland, according to the main expected flux of Rí...
The “El Sancho” reservoir (Iberian Pyritic belt, Huelva, Spain) is an acid mine drainage impacted monomictic water body (pH 3.5-4.0). During the stratification period, a deep chlorophyll maximum (DCM) develops around 22 m depth, immediately below the thermocline and at an in situ irradiance < 8 µmol m-2 s-1. In 2013, the DCM showed maximum chloroph...
Subtidal sediments of Isla del Coco (Cocos Island), Costa Rica were described in their grain size, sorting, organic matter, and carbonates from 27 dredge samples (3–75 m), collected in April 2010. The organic matter range between 1.37–3.31% and carbonates presented a mean of 74±17%. The sorting was moderately or poorly. The grain size ranged betwee...
Eighty-six water samples were collected in early 2009 from Costa Rican surface water and coastal locations for the analysis of 34 pharmaceutical and personal care product compounds (PPCPs). Sampling sites included areas receiving treated and untreated wastewaters, and urban and rural runoff. PPCPs were analyzed using a combination of solid phase ex...
El proyecto “Interacción océano-atmósfera y la biodiversidad marina del Parque Nacional Isla del Coco, Costa Rica” es financiado por el Consejo Nacional de Rectores (CONARE). Del 30 de junio al 10 de julio del 2011, un grupo de científicos del Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) de la Universidad de Costa Rica, y del Ce...
Physico-chemical parameters in coastal waters around Isla del Coco, Costa Rica (2001-2007). Four cruises to Isla del Coco (Cocos Island), Costa Rica, were carried out in order to gather oceanographic data related to surface temperature, salinity, dissolved oxygen concentration, Secchi disk depth, nutrient concentrations (nitrate, nitrite, phosphate...
Four coastal ecosystems with contrasting characteristics were sampled in Costa Rica (2000-2002). Oil pollution status, expressed as the fraction of dissolved/dispersed petroleum hydrocarbons related to chrysene equivalents, was determined by the molecular fluorescence analytical technique. A total of 130 water samples were taken, from the Caribbean...
