The density and spatial distribution of benthic viruses and prokaryotes in relation to biotic and abiotic factors were investigated in sediment cores collected in Hornsund, a permanently cold fjord on the West coast of Svalbard, Norway. The cores were obtained from the mouth of the fjord to the central basin, along a longitudinal transect. The results of our analyses showed lower densities of v...

The macrobenthic community in shallow softbottom areas in the Bay of Ancón, Peru, is characterized by low biodiversity due to low oxygen concentrations. During El Niño (EN) events, higher water temperature and higher concentrations of dissolved oxygen induce a temporary increase in biodiversity. However, the structure and dynamics of the emerging macrobenthic community and populations, especial...

We report the results of an in situ tracer experiment in an intertidal sediment, where bacterial carbon was tagged with stable carbon–isotope label, after the injection of 13C-glucose. The appearance of label in bacteria (based on label incorporation in bacteria-specific, phospholipid-derived fatty acids) and subsequent transfer to meiobenthos (group level) and macrobenthos (species level) was ...

The biodiversity of macrobenthic invertebrates two artificial hard substrates close to a mariculture plant was assessed in order understand the effect on fouling community an innovative Integrated Multi-Trophic Aquaculture (IMTA) system. examined were ( i ) vertical bare collectors that are placed around cages as new colonizable substrates, which investigated from early colonization and ii alre...

Harbours are one of the most disturbed coastal ecosystems due to intensive anthropogenic pressures. This study aimed for first time compare impacts in three harbours from central coast Tunisia (Mediterranean Sea) employing analysis heavy metal contamination and ecological quality status (EcoQS). Sampling was carried out spring 2019 fishing harbour Teboulba, marina Monastir, commercial Sousse. T...

Abstract Urbanization represents a radical transformation of natural habitats that alters all the biotic and abiotic properties governing ecosystems. Urban expansion often results in oversimplified communities, where most specialists decline or disappear few generalist exotic species become dominant. The consequences urban mangrove forests are understudied, although these systems have been alte...

Abstract Despite the general belief that Southern Ocean harbors low fish biodiversity, Weddell Sea hosts one of richest communities in region. Parallelly, is also known for presence dense and diverse macrobenthos. Most macrobenthic invertebrates, such as gorgonians, sponges bryozoans, are considered ecosystem engineers they generate a three-dimensional structure increases habitat heterogeneity....

Understanding the structure and function of infaunal communities is useful in determining biodiversity ecosystem shallow estuaries. We conducted a survey within three separate water basins [Mosquito Lagoon (ML), Indian River (IR), Banana (BR)] larger Northern Lagoon, FL, United States to establish database community function. Twenty-seven sites were sampled quarterly from 2014 2016. Analysis al...

The aim of this study was to investigate the effects fish cage culture on Macrobenthic in southern Caspian Sea. Samples were collected two offshore farms with four floating polyethylene cages a production 60 tons for 5 months 2015. Sampling performed macrobenthos, physicochemical, and sediment January, March, May, August at depths shade, 50, 100, 1000 m three geographical directions (east, west...

The SIOC project is aimed at expressing information about the structure and content of online community sites and at enabling interoperability on the Social Web using Semantic Web technologies. In this paper we briefly describe the SIOC project, introduce the SIOC Core ontology and its modules, and discuss some SIOC-based applications in terms of human and agent communication.
