“…Omnivores may have replaced filter feeders due to their ability to use more than one feeding strategy in series or in parallel (Shuai et al, 2014). According to several authors (see for instance: Mattos et al, 2013), deposit feeders are predominant in silty sediment with high OM, whereas carnivores are most abundant in sandy bottoms with low OM; however the opposite situation has been described by Manokaran et al (2013). In the present study deposit feeders and carnivores were associated both with sandy sediment and OM content, as also reported by Muniz and Pires (1999) and Barroso et al (2002).…”

“…In the present study deposit feeders and carnivores were associated both with sandy sediment and OM content, as also reported by Muniz and Pires (1999) and Barroso et al (2002). The predominance of surface deposit feeders in sandy sediment may be related to slow bottom currents (Manokaran et al, 2013), because these organisms are associated with environments characterized by low hydrodynamics (Gambi and Giangrande, 1985;Muniz and Pires, 1999;Mattos et al, 2013).…”

“…By virtue of their multiple feeding modes, polychaetes are capable alone of providing data on the trophic structure of macrobenthic communities (Bianchi and Morri, 1985). Their broad distribution in coastal and marine habitats often contributes critically to total macrofaunal diversity and abundance in benthic marine and estuarine sediment (Manokaran et al, 2013).…”

The Givetian platform of the Ardennes Massif records several alternations between a siliciclastic‐carbonate ramp and a carbonate shelf. Usually these depositional contexts are considered as a major disruption implying a perturbation of many ecological parameters. We established the impact of these variations on the biodiversity structure through the study of the trophic organisation. Thanks to a previous microfacies analysis, 550 levels of the Mont d'Haurs section in Givet and ten associated environments were precisely defined. Seven palaeotrophic levels are recognized from micropalaeontological data, including benthic, planktonic, heterotroph and autotroph organisms. The spatial and temporal distributions of these levels have been analysed through means of multivariate analyses. The statistic results show that the distribution of the palaeotrophic levels during periods characterized by a mixed ramp is not significantly different than during carbonate shelf influences. These environmental modifications do not affect the community‐type. These results support recent studies performed on different benthic communities occurring in the Givetian of the Ardennes Massif. Indeed, trilobite and ostracod faunas of this period appear more affected by global environmental changes as the Kačák (uppermost Eifelian) and Taghanic (late middle Givetian) events. Moreover, along the proximal‐distal transect on the platform, the reef constitutes the most singular environment. However, contrary with the Frasnian reefs of the Ardennes Massif, which consist of carbonate mud mounds laying on a deep mixed ramp, there is no trilobite community that appears restricted to Givetian reefs. Thus global bioevents during the Middle Devonian have a more important control on the biodiversity than the platform morphology. These results support the view that at wide scales (spatial and temporal), the biodiversity responds more positively to ecological disturbances.
