It retains symbiotic functional chloroplasts derived from its algal food Acetabularia acetabulum (Linnaeus) for 45 days. However, some aspects of the photosynthetic behaviour of the mollusc-chloroplast association are unknown. This work studies the photosynthetic characteristics of E. timida from a lagoon environment (Mar Menor), defined between 25 and 600 mu mol quanta m(-2) s(-1) by the photosynthetic-irradiance curve. Experimental data were fitted to different exponential models and models based on Michaelis-Menten kinetics. Among the latter, the model that bests fits to the experimental data was identified. Furthermore, it incorporates respiration values and allows an estimation of compensation irradiance (I-c: 11.89 mu mol quanta m(-2) s(-1)). This model showed a rapid saturation of the photosynthetic apparatus at relatively low irradiance values (I-k: 31.33 mu mol quanta m(-2)). Excess light seems to be modulated by the mollusc's opening and closing of their parapodia. Mean P/R values (Production versus Respiration relationship) are above 0.91; considered high in coral-zooxanthellae symbioses. The photosynthetic efficiency of the symbiotic chloroplasts is fairly high, taking into account that sacoglossans are more active than corals and have a higher respiration rate."@es ; dct:identifier "a74ee8c3-8564-5848-ad10-eadb2fabf8a8" ; dct:issued "2024-11-05T00:00:00+00:00"^^xsd:dateTime ; dct:language ; dct:license ; dct:modified "2026-06-25T00:00:00+00:00"^^xsd:dateTime ; dct:publisher ; dct:spatial ; dct:title "Photosynthetic activity of the solar-powered lagoon mollusc Elysia timida (Risso, 1818) (Opisthobranchia: Sacoglossa)"@es ; dct:type ; adms:identifier [ a adms:Identifier ; skos:notation "ISSN: 0334-5114" ] ; adms:status ; dcat:contactPoint ; dcat:distribution ; dcat:keyword "adaptabilidad"@es ; dcat:landingPage ; dcat:theme , . a foaf:Agent ; dct:identifier "E05068001" ; dct:type ; foaf:homepage ; foaf:mbox "bzn-datos@miteco.es" ; foaf:name "Inventario Español del Patrimonio Natural y de la Biodiversidad"@es . a dct:Location ; skos:prefLabel "Región de Murcia" ; dcat:bbox "POLYGON ((-2.3400 37.3800, -0.6900 37.3800, -0.6900 38.7600, -2.3400 38.7600, -2.3400 37.3800))"^^gsp:wktLiteral ; dcat:centroid "POINT (-1.5150 38.0700)"^^gsp:wktLiteral ; locn:geometry "POLYGON ((-2.3400 37.3800, -0.6900 37.3800, -0.6900 38.7600, -2.3400 38.7600, -2.3400 37.3800))"^^gsp:wktLiteral . a dct:LinguisticSystem . a dct:LinguisticSystem . a foaf:Document . a dcat:Distribution ; dcatap:applicableLegislation ; dcatap:availability ; dct:accessRights ; dct:format ; dct:issued "2006-07-19T00:00:00+00:00"^^xsd:dateTime ; dct:language ; dct:license ; dct:modified "2026-06-25T00:00:00+00:00"^^xsd:dateTime ; dct:title "Distribución PDF"@es ; cnt:characterEncoding "UTF-8" ; dcat:accessURL ; dcat:downloadURL ; dcat:mediaType . a vcard:Kind ; vcard:fn "Organismo publicador del Catálogo"@es ; vcard:hasEmail ; vcard:hasURL ; vcard:role . a dct:Standard . a eli:LegalResource . dct:type .
