Thermal Tolerance Limits of Heart Function in Tegula Snail Congeners of the Marine Intertidal Marine Biology

1 The marine intertidal is one of the harshest environments on earth. Organisms inhabiting the transition from land to sea are subject to a host of environmental stresses, including temperature variation, dessication stress, wave force, and salinity [1, 2]. The daily tidal cycle is largely responsible for the drastic, rapid temperature fluctuations typical of the intertidal, exposing organisms ...

Elevated CO2 affects shell dissolution rate but not calcification rate in a marine snail.

As CO(2) levels increase in the atmosphere, so too do they in the sea. Although direct effects of moderately elevated CO(2) in sea water may be of little consequence, indirect effects may be profound. For example, lowered pH and calcium carbonate saturation states may influence both deposition and dissolution rates of mineralized skeletons in many marine organisms. The relative impact of elevat...

Postglacial range shift and demographic expansion of the marine intertidal snail Batillaria attramentaria

To address the impacts of past climate changes, particularly since the last glacial period, on the history of the distribution and demography of marine species, we investigated the evolutionary and demographic responses of the intertidal batillariid gastropod, Batillaria attramentaria, to these changes, using the snail as a model species in the northwest Pacific. We applied phylogeographic and ...

Bioluminescent signals spatially amplified by wavelength-specific diffusion through the shell of a marine snail.

Some living organisms produce visible light (bioluminescence) for intra- or interspecific visual communication. Here, we describe a remarkable bioluminescent adaptation in the marine snail Hinea brasiliana. This species produces a luminous display in response to mechanical stimulation caused by encounters with other motile organisms. The light is produced from discrete areas on the snail's body...

The Dual Protection of a Micro Land Snail against a Micro Predatory Snail

Defense against a single predatory attack strategy may best be achieved not by a single trait but by a combination of different traits. We tested this hypothesis experimentally by examining the unique shell traits (the protruded aperture and the denticles within the aperture) of the micro land snail Bensonella plicidens. We artificially altered shell characteristics by removing the denticles an...
