Coral bridges : a possible light uptake strategy, by endolithic algae in mesophotic coral ecosystems
Mesophotic ecosystems are characterized for low light availability, by high water turbidity and/or depth gradient. Under these conditions autotrophic organisms like algae have different strategies to improve the light uptake. Endolithic algae Ostreobium spp. concentrates creating a dark patch to exp...

description |
Mesophotic ecosystems are characterized for low light availability, by high water turbidity and/or depth gradient. Under these conditions autotrophic organisms like algae have different strategies to improve the light uptake. Endolithic algae Ostreobium spp. concentrates creating a dark patch to exploit the available light. In these layers appear bridge-like structures between coral costae, which may be a strategy to maximize the light uptake. To prove the presence of Ostreobium spp., bridges sequencing were done using gene rbcL. Besides sequencing, an EDS (energy dispersed X-ray spectroscopy) were used to compare the elemental composition of these structures. The results show that the algae are inside the bridges. The EDS expose clear difference between the bridges and the coral skeleton. Probably the algae are recycling the boring waste to create these structures and uptake light. |

Bajo estas condiciones organismos autótrofos como las algas, tienen distintas estrategias para mejorar la captación lumínica. La alga endolitica Ostreobium spp. se concentra en la superficie del coral creando parches oscuros para aumentar la toma de este recurso. En estos parches aparece estructura como "puentes" entre las costae del coral, que posiblemente sirven para aumentar la captación lumínica. Para probar la presencia de Ostreobium spp., se realizaron secuenciaciones usando del gen rbcl. Aparte de la secuenciación, se realizo un EDS (energy dispersed X-ray spectroscopy) para comparar la composición de los puentes con la del esqueleto calcáreo del coral. Los resultados muestran que las algas están dentro de estos "puentes" y con el análisis de EDS se puede evidenciar una clara diferencia en la composición de los puentes y el esqueleto del coral. Probablemente el alga está tomando los residuos de la perforación del esqueleto para crear estas estructuras y mejorar su captación lumínica."--Tomado del Formato de Documento de Grado.BiólogoPregrado6 hojasapplication/pdfengUniversidad de los AndesBiologíaFacultad de CienciasDepartamento de Biologíainstname:Universidad de los Andesreponame:Repositorio Institucional SénecaCoral bridges : a possible light uptake strategy, by endolithic algae in mesophotic coral ecosystemsTrabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesishttp://purl.org/coar/resource_type/c_7a1fhttp://purl.org/coar/version/c_970fb48d4fbd8a85Texthttp://purl.org/redcol/resource_type/TPAlgas marinasOstreobiaceaeCoralesBiologíaPublicationhttps://scholar.google.es/citations?user=l8nad3oAAAAJvirtual::5983-10000-0001-7149-8369virtual::5983-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000057240virtual::5983-16652e019-e472-4748-9dc3-b125c616a2a4virtual::5983-16652e019-e472-4748-9dc3-b125c616a2a4virtual::5983-1ORIGINALu806828.pdfapplication/pdf685630https://repositorio.uniandes.edu.co/bitstreams/3043a0b5-fc23-4a04-a8a9-1bfa76263ae5/download964c88d2a9c005e040c037b4be1d91a4MD51TEXTu806828.pdf.txtu806828.pdf.txtExtracted texttext/plain13161https://repositorio.uniandes.edu.co/bitstreams/e52656e9-9721-439d-af7e-2433d7707fd9/download23f75a21e01a43dea0177782ddfcc8a7MD54THUMBNAILu806828.pdf.jpgu806828.pdf.jpgIM Thumbnailimage/jpeg23708https://repositorio.uniandes.edu.co/bitstreams/bca2bc0e-3c63-46f2-a94f-cd3cac23ddcb/download4119dada965e824ecfd88647a15b435cMD551992/39388oai:repositorio.uniandes.edu.co:1992/393882024-03-13 13:04:23.714http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co |
