Antifouling Activity of Synthetic Alkylpyridinium Polymers Using the Barnacle Model

open access: yesMarine Drugs, 2014
Polymeric alkylpyridinium salts (poly-APS) isolated from the Mediterranean marine sponge, Haliclona (Rhizoniera) sarai, effectively inhibit barnacle larva settlement and natural marine biofilm formation through a non-toxic and reversible mechanism ...

TWO IN ONE: REPORT OF TWO EPIBIONTS GROUPS ON THE Callinectes bocourti A. MILNE-EDWARDS, 1879 (DECAPODA: PORTUNIDAE) FROM THE AMAZON PROVINCE

open access: yesEnvironmental Smoke, 2023
Case studies reporting crustaceans acting as basibionts for a wide range of encrusting invertebrates are widely observed in the literature. For swimming crabs of the genus Callinectes, these commensal interactions are commonly observed in estuaries and ...

An ontological turn for higher education [PDF]

open access: yes, 2007
In this article, the implications of foregrounding ontology for teaching and learning in higher education are explored. In conventional approaches to higher education programmes, ontology has tended to be subordinated to epistemological concerns.

Complete mitochondrial genome of the catophragmid barnacle Catomerus polymerus (Cirripedia, Thoracica, Balanomorpha, Catophragmidae)

open access: yesMitochondrial DNA. Part B. Resources, 2018
The family Catophragmidae is one of the lower balanomorphs from traditional and recent multiple mitochondrial and nuclear markers molecular analysis. Here, we characterized the first mitogenome of the catophragmid barnacle Catomerus polymerus, which was ...

The feeding ecology of some zooplankters that are important prey items of larval fish [PDF]

open access: yes, 1984
Diets of 76 species of fish larvae from most oceans of the world were inventoried on the basis of information in 40 published studies. Although certaln geographlc, size- and taxon-specific patterns were apparent, certain zooplankton taxa appeared in the ...

Tun formation is not a prerequisite for desiccation tolerance in the marine tidal tardigrade Echiniscoides sigismundi [PDF]

open access: yes, 2016
The so-called ‘tun’ state is best known from limno-terrestrial tardigrades and rotifers that rely on this compact body shape for anhydrobiotic survival.

Bioassays and virtual screening to identify potent natural antifouling compounds from the brown macroalga Dictyota dichotoma

open access: yesOceanological and Hydrobiological Studies
Macroalgae are one of the potential natural sources for the isolation of novel eco-friendly antifouling compounds. In this study, the antifouling activity of an extract of the brown macroalga Dictyota dichotoma collected from the Red Sea was tested ...

Site fidelity and range size of wintering Barnacle Geese Branta leucopsis [PDF]

open access: yes, 2003
Barnacle Geese restrict their movements to relatively few key sites and exhibit considerable variation in ranging behaviour. To examine individual and seasonal variation in site fidelity, habitat use, range size and foraging strategies of Barnacle Geese

Matching Forces Applied in Underwater Hull Cleaning with Adhesion Strength of Marine Organisms

open access: yesJournal of Marine Science and Engineering, 2016
Biofouling is detrimental to the hydrodynamic performance of ships. In spite of advances in hull coating technology, a ship must usually undergo underwater hull cleaning to remove biofouling during her in-service time.
