ABSTRACT
The article discusses the ecological impact of the sea squirt Didemnum vexillum whose colonies have taken over large areas of the sea bed. Smothering oyster and clam beds and covering structures such as pilings and boat hulls, the squirts' proliferation is a problem for fishermen whose nets, anchors, and traps become encrusted with the colonies, and whose daily scallop take in certain areas has been diminished by more than half. At the same time, the squirt sometimes acts as a barrier for protecting small animals from predators. To protect areas such as mussel beds from sea squirts, mitigation efforts have been tried including drying out docks, wrapping them in plastic and vacuuming them; using pressurized sea water to clean them, and using hydrogen peroxide to disinfect them.

    The colonial ascidian Botryllus schlosseri forms new zooids by blastogenesis, through the formation of palleal buds which progressively grow and mature until adults are formed. At a temperature of 19°C, adult zooids remain active for about one week; then they contract, close their siphons and...

    A first step toward understanding why sociality has evolved in a particular taxonomic group is to establish comparison points by studying the organization of different social systems. We examined the social organization and spatial distribution of individuals in colonies of the undescribed...

    The European flat oyster (Ostrea edulis) was described in Mali Ston Bay (Eastern Adriatic coast, Croatia). Metaphase spreads were made from the flat oyster larvae and studied using conventional karyotyping methods. The study revealed the presence of 5 metacentric and 4 submetacentric pairs of...

    The bloom-forming prymnesiophyte Phaeocystis globosa forms hollow, spherical, mucilaginous colonies that vary from micrometres to millimetres in size. A recent paper gave the first empirical evidence that colony size increase in P. globosa is a defensive response against grazers, and knowing the...
