...David Taylor ABSTRACT Experiments and observations were carried out to investigate the response of the Patella vulgata limpet shell to impact . Dropped-weight impact tests created damage that usually took the form of a hole in the shell's apex. Similar damage was found to occur naturally...

...Yunwei Dong; George N. Somero SUMMARY We characterized functional and structural properties of cytoplasmic malate dehydrogenases (cMDHs) from six limpets of the genus Lottia that have different vertical and latitudinal distributions. Particular attention was given to the cryptic species pair Lottia...

... synthesis, degradation and growth rates in free-ranging Antarctic limpets ( Nacella concinna ), together with protein synthesis rates at temperatures ranging between –1.5°C and 6.0°C. PSRE were not significantly different in summer (15.69±4.41%) or winter(20.59±4.45%), but values were considerably lower...

... to predict the body temperature of intertidal organisms whose heat budgets are strongly affected by conduction to and from the substratum. Here, we propose a simple heat-budget model of one such animal,the limpet Lottia gigantea , and test the model against measurements made in the field. Working solely from...

...Mark W. Denny; Luke P. Miller; Christopher D. G. Harley SUMMARY When coupled with long-term meteorological records, a heat-budget model for the limpet, Lottia gigantea , provides a wealth of information regarding environmental and topographic controls of body temperature in this ecologically...

...Gary K. Ellem; John E. Furst; Kenneth D. Zimmerman SUMMARY The behaviour of clamping the shell against the substratum may play an important role in the limpet adhesion mechanism because friction generated by this behaviour resists dislodgement by shear forces. This paper describes the development...

...Mark W. Denny ABSTRACT Limpets are commonly found on wave-swept rocky shores, where they may be subjected to water velocities in excess of 20 m s − . These extreme flows can impose large forces (lift and drag), challenging the animal’s ability to adhere to the substratum. It is commonly thought...

...Mark W. Denny; Carol A. Blanchette ABSTRACT On wave-swept rocky shores, limpets are subjected to water velocities in excess of 20 m s −1 , which may impose large hydrodynamic forces. Despite the extreme severity of this flow environment, predictions from conical models suggest that limpets’ shells...

... of drag fluctuations for five objects: a flat plate, large and small cylinders, a sphere and a limpet shell. Distributions vary substantially among different objects exposed to the same mainstream flow; the sphere and limpet exhibit larger fluctuations than the plate and cylinders. The distribution...
