Behavioral Control of Swash-Riding in the Clam Donax variabilis.

Form and Motion of Donax variabilis in Flow.

The coquina clam, Donax variabilis, rides flow from waves, migrating shoreward during rising tides and seaward during falling tides. This method of locomotion, swash-riding, is controlled not only behaviorally but also morphologically. The shape of this clam causes it to orient passively; a clam rotates in flow, usually in backwash, until its anterior end is upstream. Rotation is about a vertic...

Discrimination Among Wave-Generated Sounds by a Swash-Riding Clam.

Clams, Donax variabilis, responded to sound stimuli presented to them in a laboratory aquarium by jumping out of the sand, lying on the sand for several seconds, and digging in again. On a beach, clams jump out of the sand and ride waves, migrating shoreward with the rising tide and seaward with the falling tide. Parallels between clam behavior on a beach and that elicited in the laboratory sug...

Short communication:Population dynamics of Donax faba (Family: Donacidae)in the coastal waters of Padukere, Karnataka (India)

Null alleles are ubiquitous at microsatellite loci in the Wedge Clam (Donax trunculus)

Recent studies have reported an unusually high frequency of nonamplifying alleles at microsatellite loci in bivalves. Null alleles have been associated with heterozygous deficits in many studies. While several studies have tested for its presence using different analytical tools, few have empirically tested for its consequences in estimating population structure and differentiation. We characte...

First complete female mitochondrial genome in four bivalve species genus Donax and their phylogenetic relationships within the Veneroida order

BACKGROUND Four species of the genus Donax (D. semistriatus, D. trunculus, D. variegatus and D. vittatus) are common on Iberian Peninsula coasts. Nevertheless, despite their economic importance and overexploitation, scarce genetic resources are available. In this work, we newly determined the complete mitochondrial genomes of these four representatives of the family Donacidae, with the aim of c...
