Long-term variation in size of Gammarus lacustris, in Øvre Heimdalsvatn in relation to introduction of European minnow (Phoxinus phoxinus). Data on juveniles, males and females in 1972, 1976, 1985, 1986 and 2000 at stations around the lake.
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 2 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.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
The table below shows only published versions of the resource that are publicly accessible.
