Settlement of barnacle, a major fouling organism is believed to be controlled to a great extent by substratum characteristics such as, presence of conspecific adults or "gregariousness" inducing factors. Exopolymers secreted ...

The influence of food concentration (Chaetoceros calcitrans at 1 x 10 sup(5) and 2 x 10 sup(5) cells ml sup(-1)) and temperature (20 degrees C and 30 degrees C) on the nucleic acid content of the nauplii and the cyprids ...

Gregarious settlement in barnacles has been related to the settlement-inducing compounds from adult conspecifics, bacteria in the biofilms, and their interaction. Elucidation of larval settlement cues from these sources ...

The possibility of cryopreserving B. amphitrite (Cirripedia; thoracica) nauplii is explored. The effects on the postthaw survival of a range of cryobiological variables are reported; three different cryoprotectants (ethylene ...

Natural biofilms constitute a complex network of microorganisms (bacteria, diatoms, protozoa, fungi) and their extracellular polymeric substances (EPS), which influence settlement inbenthic invertebrates. The influence of ...

Energy content in the non-feeding (lecithotrophic) cyprid larvae of B. amphitrite plays an important role in determining its metamorphic characteristics. In this context it is important to understand the energy transformed ...

The influence of bacterial exopolymers and conspecific adult extract of Balanus amphitrite on metamorphosis of cyprid larvae at different salinities has been evaluated through laboratory assay. The bacterial exopolymers ...

Modulation of metamorphosis in barnacles in response to cues of biological origin is established. The bacteria associated with the barnacles also have a role in such modulations. We isolated the bacteria, Pseudomonas ...

An evaluation of starvation threshold of the newly hatched Balanus amphitrite nauplii (instar, II) has been made at three different temperatures (5, 15 and 25°C). Earlier studies on starvation in crustacean larvae demonstrated ...
