The small average size of the component individuals indicates that they are representatives of recent spawning. It is suggested that such swarms reached the islands from the NW sector. Description: The author wishes to acknowledge the contribution of the Maritime Section of the Task Force, Malta in the collection of data. 1984-01-01T00:00:00Z https://www.um.edu.mt/library/oar/handle/123456789/37473 Title: CENTRO : volume 1 : issue 1  Editors: Axiak, Victor Abstract: Table of contents: 1/ REUTHER, C.

Observations were made at a number of stations at four depths on the occurrence of various species of molluscs and their environment (type of sediment, temperature, pH, dissolved oxygen and salinity of the water) at each site. General conclusions are drawn on the distribution of the species at these depths. Arcularia gibbosula proved to be the most abundant living species in the bay as well as a suitable indicator for mercury pollution. 1984-01-01T00:00:00Z https://www.um.edu.mt/library/oar/handle/123456789/37471 Title: Tectonics of the Maltese Islands Authors: Reuther, Claus-Dieter Abstract: The Maltese Islands are a key area in the Central Mediterranean for understanding the development of faulting and foreland reactions on the northern edge of the African plate. Convergent and lateral motions along the Afro-Eurasian plate boundary generated different and superimposed stress regimes in the sedimentary cover, which governed the fracture pattern and fault processes. 1984-01-01T00:00:00Z
