2001 Castro-Longoria, E. Southampton Water Acartia tonsa records
Eggs produced by four Acartia species from the Solent-Southampton Water estuarine system were examined. Acartia tonsa produced two morphologically distinct types of eggs, which were identified as subitaneous and diapause. Diapause eggs from this species were spiny while the subitaneous form had a relatively smooth chorion surface; a second subitaneous egg was produced by A. tonsa, which had significant spine extensions on the surface. Acartia margalefi, A. discaudata, and A. clausiproduced only smooth eggs, which were identified as subitaneous. Observations under scanning electron microscopy (SEM) revealed consistent interspecific variations in the texture of the chorion surface of both subitaneous and diapause eggs in all species.

Part of MSFD NNS baseline data collation project (Jan 2016). Subset of a dataset as we were only pulling out records for a selection of INNS. Contains records for Acartia tonsa. 'If any sensitive species or biotope records are present within this dataset, they will have been removed. If you wish to request access to sensitive species records, please contact the metadata contact. The UK Sensitive Species list has been agreed by UK statutory bodies and relevant experts. It can be viewed here https://docs.nbnatlas.org/sensitive-species-list/. Please note sensitive species lists can vary across the UK. See Castro-Longoria, E. (2001).
