Photosynthetic epibionts and endobionts of Pacific oyster shells from oyster re...
Barillé, Laurent; Le Bris, Anthony; Méléder, Vona; Launeau, Patrick; Robin, Marc; Louvrou, Ioanna; Ribeiro, LourençoThe Pacific oyster, Crassostrea gigas (Thunberg), is the main bivalve species cultivated in the world. With global warming enabling its reproduction and larval survival at higher latitudes, this species is now recognized as invasive and creates wild oyster reefs globally. In this study, the spatial distribution of photosynthetic assemblages colonizing the shells of wild C. gigas was investigated on both a large...
Seasonality of microphytobenthos revealed by remote-sensing in a south european...
Brito, Ana C.; Benyoucef, Ismaїl; Jesus, Bruno; Brotas, Vanda; Gernez, Pierre; Mendes, Carlos Rafael; Launeau, Patrick; Dias, Maria P.; Barillé, LaurentThe spatio-temporal variation of microphytobenthos (MPB) at the scale of a large estuary (Tagus estuary, Portugal) was studied using a combination of field and satellite remot esensing data during 2003.This is the first attempt to use remote sensing to study MPB in an ecosystem with a Mediterranean -like climate. Satellite pour l'Observation de la Terre(SPOT) and Medium Resolution Imaging Spectrometer(MERIS) im...
In vivo estimation of pigment composition and optical absorption cross-section ...
Méléder, Vona; Laviale, Martin; Jesus, Bruno; Mouget, Jean Luc; Lavaud, Johann; Kazemipour, Farzaneh; Launeau, Patrick; Barillé, LaurentThe objective of the present study was to estimate in vivo pigment composition and to retrieve absorption cross-section values, a*, of photosynthetic micro-organisms using a non-invasive technique of reflectance spectrometry. To test the methodology, organisms from different taxonomical groups and different pigment composition were used (Spirulina platensis a Cyanophyta, Porphyridium cruentum a Rhodophyta, Duna...
