The impact of climate change on many different ecosystems is a growing concern. Intertidal filter feeders, such as barnacles, play an important role in repairing the water quality and contributing to the stability of the ecosystem. This experiment aimed to look at the effect of different aerial exposure temperatures on Balanus balanoides feeding behaviors. Barnacles were exposed to 4°C, 12°C, a...

The mechanical properties of barnacle base plates were measured using a punch test apparatus, with the purpose of examining the effect that the base plate flexural rigidity may have on adhesion mechanics. Base plate compliance was measured for 43 Balanus amphitrite (=Amphibalanus amphitrite) barnacles. Compliance measurements were used to determine flexural rigidity (assuming a fixed-edge circu...

In this study eight di€erent species of barnacles were found within nine species of sponges from the Red Sea. This brings to 11 the number of sponge-symbiotic barnacles reported from the Red Sea, two of these are new Acasta species (not described herein) and one (A. tzetlini Kolbasov) is a new record for this sea. This number is much higher than that of symbiotic barnacles found within sponges ...

The frequency and distribution of barnacle (Chelonibia patula) on blue swimmer crab Portunus pelagicus off Persian Gulf Coasts were studied. A total of 545 crabs were examined and were of the same size range. The carapace width rangof crab werefrom 6.5cm to 16.5cm, carapace length from 4 to 8cm and weighed 80.5g to 220.4g. The barnacles were attached to the carapace, abdomen and walking legs. T...

Sea turtles are known to host diverse communities of plants and invertebrate animals (Caine 1986; Kitsos et al. 2005; Robinson et al. 2017). Past analyses of the size, abundance, and/or species composition of the organisms present on an individual turtle have provided insight into the health (e.g. Flint et al. 2009), habitat use (e.g. Pfaller et al. 2014), and movement (e.g. Killingley and Lutc...

The small honeycomb barnacle Chamaesipho tasmanica Foster and Anderson often forms continuous sheets covering the substratum at mid-shore levels of sheltered rocky shores but also occurs in sparse distributions on exposed shores, and on higher levels of sheltered shores, in south-eastern Australia. Larger barnacles are generally found in more exposed and higher areas. Effects of each site on ul...

Dear Sir: The existence of sodium binding or compartmentalization in single muscle fibers from giant barnacles was the basis for two recent letters in this Journal (McLaughlin, 1968; Brinley, 1968 b). Evidence for sodium binding from this laboratory is criticized by Brinley (1968 a, see Discussion) because our analytic value for total internal sodium concentration is higher than values obtained...

In the marine environment, the antifouling (AF) properties of various kinds of hydrogels against sessile marine organisms (algae, sea squirts, barnacles) were tested in a long-term experiment. The results demonstrate that most hydrogels can endure at least 2 months in the marine environment. In particular, mechanically tough PAMPS/PAAm DN and PVA gels exhibited AF activity against marine sessil...
