CIECEM
El Centro Internacional de
Estudios y Convenciones Ecológicas y Medioambientales (CIECEM),
sito en el Parque Dunar (Matalascañas), es un Centro del Plan
Andaluz de Investigación dependiente de la Universidad de Huelva.
El CIECEM se plantea como mecanismo de coordinación,
planificación y gestión de la investigación dentro del Plan
Andaluz de Investigación (PAI), con el fin de fomentar una labor
de I+D+I de calidad en el ámbito de las ciencias medioambientales
y ecológicas.
Dentro del CIECEM, El Centro de Documentación Ambiental se
configura como una eficaz herramienta de obtención de
información, estimulando la transferencia del conocimiento y
ofreciendo servicios de apoyo para el aprendizaje, la docencia,
la investigación y la formación continua. Su actividad se
desarrolla a través de servicios digitales en el ámbito del Medio
Ambiente y el Desarrollo Sostenible. Por otro lado, se constituye
como el servicio de gestión de la información y documentación
generada por el CIECEM, participando como estructura transversal
en todas sus líneas e investigación.

Enhancement of carotenoid production in Nannochloropsis by phosphate and sulphur limitation
Forján Lozano, Eduardo; Garbayo Nores, Inés; Casal Bejarano, Carlos; Vílchez Lobato, Carlos (Formatex, 2007)
Because of its value as antioxidants, food-supplements and in animal-feeding, carotenoids are among the most attractive target compounds of marine microalgae. In this contribution the influence of essential nutrients (N, ... -
UV-A promotes long-term carotenoid production of Dunaliella in photobioreactors with retention of cell viability
Mogedas, Benito; Salguero, A.; Casal Bejarano, Carlos; Vílchez Lobato, Carlos (Formatex, 2007)
The effect of adding UV-A radiations (320-400 nm) to photosynthetically active radiation (PAR, 400-700 nm) during the growth of Dunaliella bardawil in an air-fluidized bed photobioreactor was studied to evaluate cell ... -
Marine carotenoids: biological functions and commercial applications
Vílchez Lobato, Carlos; Forján Lozano, Eduardo; Cuaresma Franco, María; Bédmar, Francisco; Garbayo Nores, Inés; Vega, José M. (MDPI, 2011)
Carotenoids are the most common pigments in nature and are synthesised by all photosynthetic organisms and fungi. Carotenoids are considered key molecules for life. Light capture, photosynthesis photoprotection, excess ... -
Assessing freshwater fish sensitivity to different sources of perturbation in a Mediterranean basin
Hermoso López, Virgilio; Blanco Garrido, Francisco; Clavero Pineda, Miguel; Prenda Marín, José (Wiley-Blackwell Publishing, INC, 2009)
The accuracy of bioassessment programs is highly limited by the precision of the systems used to derive sensitivity-tolerance values for the organisms used as indicators. We provide quantitative support to the objective ... -
Addressing longitudinal connectivity in freshwater systematic conservation planning
Hermoso López, Virgilio; Linke, Simon; Prenda Marín, José; Possingham, Hugh (Wiley-Blackwell, 2011)
1. Freshwater conservation has received less attention than its terrestrial or marine counterparts, despite freshwater systems containing a considerable amount of the earth´s biodiversity. Given the accelerated rate of ... -
Assessing the ecological status in species-poor systems: a fish-based index for Mediterranean Rivers (Guadiana River, SW Spain)
Hermoso López, Virgilio; Clavero Pineda, Miguel; Blanco Garrido, Francisco; Prenda Marín, José (Elsevier, 2011-02-15)
The assessment of the ecological status of freshwater ecosystems is a key issue for many international laws as the Water Framework Directive in light of the actual impoverished status of such ecosystems. Different ... -
Enhanced productivity of a lutein-enriched novel acidophile microalgae grown on urea
Casal Bejarano, Carlos; Cuaresma Franco, María; Vílchez Lobato, Carlos; Vega Piqueres, José María (MDPI, 2011)
Coccomyxa acidophila is an extremophile eukaryotic microalga isolated from the Tinto River mining area in Huelva, Spain. C. acidophila accumulates relevant amounts of b- carotene and lutein, well-known carotenoids with ... -
β-Carotene production enhancement by UV-A radiation in Dunaliella bardawil cultivated in laboratory reactors
Vílchez Lobato, Carlos; Mogedas Romero, Benito; Casal Bejarano, Carlos; Forján Lozano, Eduardo (Elsevier SCI LTD, 2009)
β-carotene is an antioxidant molecule of commercial value that can be naturally produced by certain microalgae that mostly belong to the genus Dunaliella. So far, nitrogen starvation has been the most efficient condition ... -

Productivity and selective accumulation of carotenoids of the novel extremophile microalga Chlamydomonas acidophila grown with different carbon sources in batch systems
Vílchez Lobato, Carlos; Cuaresma Franco, María; Forján Lozano, Eduardo; Casal Bejarano, Carlos (2010)
Cultivation of extremophile microorganisms has attracted interest due to their ability to accumulate high-value compounds. Chlamydomonas acidophila is an acidophile green microalga isolated by our group from Tinto River, ... -
Distribution and habitat preferences of the introduced mummichog Fundulus heteroclitus (Linneaus) in southwestern Spain
The distribution and apparent habitat preferences of the common mummichog (Fundulus heteroclitus) in southwestern Spain were examined during summer-fall 1996. This introduced species was more or less continuously distributed ... -

Spatio-temporal distribution and ecological preferences of coexisting hydropsychid species (Trichoptera) in two Mediterranean river basins (S Spain)
The hydropsychids of two Mediterranean river basins in southern Spain (Guadaira and Guadalete) were investigated from January 1988 to January 1989. The distribution of hydropsychids along an environmental gradient related ... -
