Correlation between surface chemistry and settlement behaviour in barnacle cyprids (Balanus improvisus).
In laboratory-based biofouling assays, the influence of physico-chemical surface characteristics on barnacle settlement has been tested most frequently using the model organism Balanus amphitrite (= Amphibalanus amphitrite). Very few studies have addressed the settlement preferences of other barnacle species, such as Balanus improvisus (= Amphibalanus improvisus). This study aimed to unravel th...
متن کاملThe identification and role of a novel eicosanoid in the reproductive behaviour of barnacles (Balanus balanus).
Post-copulatory behaviour in barnacles involves a violent rocking movement of the opercular valves, which is thought to contribute to the expulsion of oocytes through the oviduct into the mantle cavity where they are fertilised. We demonstrate in this study that the seminal vesicles/testis of the subtidal barnacle Balanus balanus produce a biologically active factor, barnacle muscle stimulatory...
متن کاملOctopamine receptors from the barnacle balanus improvisus are activated by the alpha2-adrenoceptor agonist medetomidine.
G protein-coupled octopamine receptors of insects and other invertebrates represent counterparts of adrenoceptors in vertebrate animals. The alpha(2)-adrenoceptor agonist medetomidine, which is in clinical use as a veterinary sedative agent, was discovered to inhibit the settling process of barnacles, an important step in the ontogeny of this crustacean species. Settling of barnacles onto ship ...
متن کاملProximate Causes of Mortality Determin Distribution and Abundance of the Barn Balanus improvisus Darwin in Chesapeake Bay
The effects of predation and competition on survival of the barnacle, Balanus improvims Darwin, in the upper Chesapeake Bay varied from location to location in 1972 and probably vary from year to year. The flatworm, Stylochus ellipticus Girard, was the predominant predator on barnacles, and the bryozoan, Victorella pavida Kent, was the major spatial competitor. Those intertidal barnacles not ki...
متن کاملAnalysis of behavioural rejection of micro-textured surfaces and implications for recruitment by the barnacle Balanus improvisus.
Experiments performed in the field and in the laboratory show that the barnacle, Balanus improvisus, preferentially settles on smooth surfaces. Settlement and recruitment of B. improvisus was evaluated on micro-textured surfaces with scales of surface texture ranging from 1 to 100 µm in profile heights. Surface texture with profile heights within a topographic range of 30-45 µm reduced settleme...
