Gregarious settlement, an essential behavior for many barnacle species that can only reproduce by mating with a nearby barnacle, has long been thought to rely on larval ability to recognize chemical signals from conspecifics during settlement. However, the cyprid, the settlement stage larva in barnacles, has one pair of compound eyes that appear only at the late nauplius VI and cyprid stages, b...
Marine biofouling poses a severe threat to maritime and aquaculture industries. To prevent the attachment of marine biofouling organisms on man-made structures, countless cost and effort was spent annually. In particular, most attention has been paid on the development of efficient and environmentally friendly fouling-resistant coatings, as well as larval settlement mechanism of several major b...
The p38 mitogen-activated protein kinase (p38MAPK) plays a key role in larval settlement of the barnacle Amphibalanus amphitrite. To study the signaling pathway associated with p38MAPK during larval settlement, we sought to identify the upstream kinase of p38MAPK. Three MKKs (MKK3, MKK4 and MKK7) and three MAPKs (p38MAPK, ERK and JNK) in A. amphitrite were cloned and recombinantly expressed in ...
چرخه‌ی زندگی بسیاری از بی‌مهرگان دریایی دارای یک دوره لاروی است که در طی آن جانور بیشترین حساسیت را نسبت به استرس‌های محیطی داردکه در انجام تست‌های سمیت در بسیاری از مطالعات مقایسه می‌گردد .بارناکل‌ها سخت پوستانی کفزی، دارای جایگاهی آهکی می‌باشند که در حالت بلو غ ساکن‌اند و با پایه‌ای خود را به اجسام داخل آب می‌چسبانند. چرخه زندگی بارناکل‌ها به طور معمول شامل دو مرحله می‌باشد: مرحله لاروی با شن...
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...
کشتی چسب ها از موجودات غالب گروه ماکروفولینگ ها (macrofoulings) هستند که در نواحی بین جزرومدی سراسر جهان یافت می شوند. در این مطالعه، اثرات تغذیه ی جلبکی با استفاده از گونه های chaetoceros calcitrans، ch. muelleri، isochrysis galbana، tetraselmis suecica و chlorella vulgaris به صورت تک جلبکی و ترکیبی بر روی میزان متاموفوز لارو کشتی چسب amphibalanus amphitrite مورد بررسی قرار گرفت. لاروهای گرفته...
The barnacle Balanus ( = Amphibalanus) amphitrite is a major marine fouling animal. Understanding the molecular mechanism of larval settlement in this species is critical for anti-fouling research. In this study, we cloned one isoform of p38 MAPK (Bar-p38 MAPK) from this species, which shares the significant characteristic of containing a TGY motif with other species such as yeast, Drosophila a...
