Description

The experiment was designed to study long-term changes in communities strucutre in response to global change (climatic change) and local anthropogenis pressures (e.g. eutrophication). Muddy sand macrobenthic communities are monitored five times a year at the "Rivière de Morlaix" site. The different parameters wich are measured are: (1) total and specific abundances, (2) specific richness

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 97 records.

2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

Sampling Methods

Macrofauna is sampled using a Smith McIntyre grab covering a surface of 0.1 m2. Ten replicates are collected at each sampling date.

Study Extent Fine sand macrobenthic communities long-term monitoring in Rivière de Morlaix site (Bay of Morlaix - France).

Method step description:

  1. After collection, the sediment was sieved (1 mm circular mesh) and the retained material is fixed with 10 % neutralized formalin prior to analysis in the lab. In the laboratory, organisms are sorted, identified to species level and stored in a 70% ethanol solution.
