dc.description.abstractAll marine species studied thus far show rhythmic temporal patterns in their behavioural, physiological, and molecular functions, which are collectively known as biological rhythms. Biological rhythms are generated by biological clocks that time biological functions and are synchronised by geophysical cycles such as the solar light-dark cycle and tidal cycle. On continental margins, behavioural rhythms can be detected by diel (i.e., 24-h based) or seasonal periodical trawling as a consequence of massive inward and outward displacements of populations to and from the sample areas. As a result, significant errors in population/stock and biodiversity assessments performed by trawling may occur if timing of sampling is not taken into account. The increasing number of cabled and permanent multiparametric seafloor observatories now allows direct, continuous, and long-lasting monitoring of benthic ecosystems and analysis in relation to several habitat cycles. This review describes the adaptation of this technology to investigations of rhythmic behaviour by focusing on automated video-imaging. Diel fluctuations in the number of video-observed individuals can be used as a measure of average population rhythmic behaviour. The potential implementation of automated video image analysis in relation to animal tracking and classification procedures based on the combined use of morphometric tools and multivariate statistics is detailed in relation to populational and community studies. Based on video cameras mounted at multiparametric cabled observatories, an integrated time-series analysis protocol using chrono-biomedical procedures is proposed to place video-recorded bio-information in an oceanographic contextes_ES
dc.description.sponsorshipThe present work was developed within the framework of five research projects funded by the Spanish Ministry for Science and Innovation (PROMETEO, ref. CTM 2007-66316-C02-02; RITFIM, ref. CTM2010-16274; Operatividad Laboratorio Submarino OB SEA ref. ACI2009-0983; DOS MARES, ref. CTM2010-21810-C03-03; and finally GRACCIE-CONSOL IDER INGENIO 2010, ref. CSD2007-00067) and the Italian Ministry of Agricultural, Food and Forestry Politics-MIPAAF (HighVision, DM 19177/7303/08). The E.U.-funded HERMIONE (ref. 226354-HERMIONE), EMSO-PP (grant agreement no. 211816), the KM3NeT-PP (grant agreement no. 212525), and finally the PERSEUS (CE, VII PM, Grant Agreement no: 287600) RTD projects of the VII Framework Programmes should be equally acknowledged along with the CRG Marine Geosciences (grant 2009 SGR 1305) at the University of Barcelona (Generalitat of Catalunya).
