Composition of the essential oil from leaves of Smallanthus quichensis (Asteraceae) from Costa Rica
(2015-09-30)Smallanthus is a genus of flowering plants in the Asteraceae family, which has about 24 species, ranging mostly from southern Mexico and Central America to the Andes in South America. The aim of the present study was to ... -
Novel Lobophorins Inhibit Oral Cancer Cell Growth and Induce Atf4- and Chop-Dependent Cell Death in Murine Fibroblasts
(2015-07-06)As part of the International Cooperative Biodiversity Groups (ICBG) Program, we were interested in identifying biologically active unfolded protein response (UPR) inducing compounds from marine microorganisms isolated from ... -
Sexual dimorphism in the second-to-fourth digit length ratio in green anoles, Anolis carolinensis (Squamata: Polychrotidae), from the southeastern United States
(2006)Digit length ratios are organized during embryonic development and may show sexual dimorphism related to steroid exposure. The second-to-fourth digit length ratio (2D:4D) has received the most attention. In the present ... -
Borrelidin Induces the Unfolded Protein Response in Oral Cancer Cells and Chop-Dependent Apoptosis
(2015)Oral squamous cell carcinoma (OSCC) is the most common cancer affecting the oral cavity, and US clinics will register about 30,000 new patients in 2015. Current treatment modalities include chemotherapy, surgery, and ... -
Essential oil composition of Ambrosia cumanensis (Asteraceae) from Costa Rica
(2015-08)Ambrosia is an Asteraceous genus of flowering plants, which has about 40-45 species, and their geographical distribution ranges from the USA, Mexico, and Central America to South America. The aim of this work was to study ... -
Macrofauna bentónica de las playas de arena del Área de Conservación Osa, Puntarenas, Pacífico Sur de Costa Rica
(2015)Se describe la diversidad y composición de especies las playas de arena del Pacífico Sur de Costa Rica. En las playas de arena de la región, se colectó individuos de la infauna por medio de barrenos. Para la zona de entre ... -
Feeding ecology of common demersal elasmobranch species in the Pacific coast of Costa Rica inferred from stable isotope and stomach content analyses
(2015)Knowledge of the feeding ecology and trophic interactions of marine species is essential to understanding food web dynamics and developing ecosystem-based management approaches. Given that many top predatory fishes have ... -
Effects of simulated overfishing on the succession of benthic algae and invertebrates in an upwelling-influenced coral reef of Pacific Costa Rica
(2015)Overfishing and nutrient enrichment are among the major local stressors to coral reefs worldwide, as they can alter the benthic reef community by promoting fast growing algae and bioeroders. The Northern coast of Pacific ... -
Hierarchical spatial patterns in Caribbean reef benthic assemblages
(2015)Aim: Coral assemblages on Caribbean reefs have largely been considered to be biogeographically homogeneous at a regional scale. We reassess this in three taxa (corals, sponges and octocorals) using three community attributes ... -
Evaluation of Extreme Waves Associated with Cyclonic Activity on San Andrés Island in the Caribbean Sea since 1900
(2015)San Andrés Island is one of the most important tourist destinations in the Caribbean Sea. The extreme waves associated with storms and hurricanes since 1900 were studied. A total of 17 important events was identified in ... -
Simulación de oleaje de huracán usando modelos de viento paramétricos en un modelo de olas de Tercera Generación
(2006)Dos modelos paramétricos de viento fueron usados para simular la distribución del oleaje en huracanes en uno de los, así llamados, modelos de tercera generación. Se usaron varias condiciones durante huracanes en el Golfo ... -
Uso del análisis de correlación canónica para la predicción de la precipitación pluvial en Centroamérica
(2007)Se usó un modelo basado en el análisis de correlación canónica, para explorar la capacidad de predicción de las estaciones lluviosas mayo-junio-julio (MJJ) y agosto-septiembre-octubre (ASO) en Centroamérica. Se usaron como ... -
Escenarios climáticos para temporadas con alto y bajo número de huracanes en el Atlántico
(2007-06-01)Se estudió la relación entre la variación de la actividad anual de los ciclones tropicales en el Atlántico y las variaciones decadales e interanuales de la Temperatura Superficial del Mar (TSM). Utilizando el análisis de ... -
El desarrollo de los proyectos de energía eólica en Costa Rica (1979-2005)
(2006)El último cuarto del siglo XX se caracterizó por la explotación de nuevas fuentes de energías no convencionales para la producción de electricidad en Costa Rica: geotérmicas, solares, biomásicas y eólicas. A diferencia de ... -
Predicción Estacional del Clima en Centroamérica mediante la reducción de escala dinámica. Parte I: Evaluación de los Modelos de Circulación General CCM3.6 y ECHAM4.5
(2008)Mediante la evaluación del campo vectorial de viento en bajo nivel y de precipitación derivados de dos modelos de circulación general (ECHAM4.5 y CCM3.6), para el perıodo 1990-1999, se determinó la habilidad de dichos ... -
The Intra-Americas Sea Low-level Jet
(2008-12-05)A relevant climate feature of the Intra‐Americas Sea (IAS) is the low‐level jet (IALLJ) dominating the IAS circulation, both in summer and winter; and yet it is practically unknown with regard to its nature, structure, ... -
Algunas características de las mareas en la costa Pacífica y Caribe de Centroamérica
(2006)Tidal levels were studied in 48 stations using tidal predictions along the coasts of the Pacific and Caribbean of Central America. Statistics of basic mean values were analyzed to characterize the stations. These ...
