Brine disposal from desalination plants alters marine benthic assemblages.300 desalination plants are currently working in the Canarian archipelago and their brine effluents affect recipient assemblages, reducing species richness and abundance of individuals. However, the densities of several species are favoured in altered areas, thus, they could be conrtunistsider as oppos. The main drawback of this environmental perturbation consists of separating hypersaline brine from the indirect effects of continuous flow on grain size composition. Check it out! Riera, R., F.

Aquaculture industry can produce changes in the natural environment, threatening the environmental quality of coastal areas. Aquaculture industry can produce changes in the natural environment, threatening the environmental quality of coastal areas.Monitoring programs include environmental indicators, and one of the most reliable ones are meiofaunal communities (organisms with 0.063-0.5 mm range size). They can be considered a reliable bioindicator to detect changes from off-shore cages. For more information, check it out! More info at Riera, R., P. Sánchez-Jérez, M. Rodríguez, Ó. Monterroso, E.

The importance of Maërl Beds in subtidal seabeds.A mosaic of seabed habitats was determined by the variations of sediment grain size, which enhances local macrofaunal diversity. Maërl beds were characterized by high diverse assemblages, with intermediate values between seabeds colonized by Cymodocea nodosa and Garden eels (High) and sandy bare seabeds (Low). The characterization of maërl beds is important to understand the ecosystem functioning of this fragile and slow-growth ecosystem that could be affected by anthropogenic disturbances in the near future (harbours, pipelines, desalination plants, fish cages, etc.).
