one of the biological elements to be assessed is phytobenthos
, with diatoms now being routinely monitored as part of the national wfd monitoring programme for rivers and lakes.
All values determined in this work fell within this range and, while the February through June progressive increase was most probably due to the photosynthetic activities of phytoplankton and phytobenthos
, which caused at the same time the high dissolved [O.
The WFD requires ecological quality assessment of running waters based on various biotic (phytoplankton, macrophytes, phytobenthos
, benthic invertebrates, and fish fauna), chemical, and hydromorphological elements (European Commission, 2000).
However, this is a perennially harsh environment for phytobenthos
colonization and proliferation.
They cover design and analysis in benthic surveys in environmental sampling, characterizing the physical properties of seabed habitats, imaging techniques, diving, macrofauna and meiofauna techniques, deep-sea benthic sampling, measuring the flow of energy and matter in marine benthic animal populations, and phytobenthos
Desiccation and recolonization of phytobenthos
in a regulated desert river: Colorado river at Lees Ferry Arizona, USA.
Natural and anthropogenic factors influence physical and chemical lake variables and aquatic biota, especially environmentally sensitive phytoplankton, phytobenthos
, zooplankton and zoobenthos communities.
Despite the Banado Carilauquen's ecological fragility, its economic potential and the importance it holds to conservation, knowledge about the invertebrate organisms of the area is limited to phytobenthos
and plankton (Peralta & Fuentes, 2005) and to invertebrate fauna from the littoral benthos (Ciocco & Scheibler, 2008; Scheibler & Ciocco, 2011).
Observations on the phytobenthos
of freshwater Thames II.
Primary photosynthetic production can take place in the sea-bottom by phytobenthos
, and in the water column by phytoplankton.
