European Ocean Biodiversity Information System

The macrozoobenthic community structure in the innermost part of Laki lagoon showed a seasonal periodicity. During summer the macrobenthic fauna became impoverished, but recovered from late summer onwards. The seasonal dynamics of the assemblage was mainly governed by water temperature. Predation pressure by Atherina boyeri may have contributed to quantitative community changes during autumn. The sediment samples were taken using a small corer for particle size analysis and estimation of the amount of organic matter. Two samples of epibenthic decapods and small fish were taken using a special net (with a 40·40 cm opening) which was pulled on the sediment for a distance of 10 m) A number of datarecords are uncertain, and are therefore not included in Eurobis.
