On the Structure and Adaptations of Pandora inaequivalvis and

نویسنده

  • J. A. ALLEN
چکیده

The two British species of Pandora are adapted for life on muddy-sand. P. inaequivalvis is taken from very sheltered shores at low-water mark and down to 10 fathoms. P. pinna is taken from depths of over 40 fathoms. Both species are markedly inequivalve. This is probably connected with the habit of lying horizontally. The mantle muscles and the ciliary mechanisms of the mantle and gills are described. An account of the morphology and the functioning of the stomach is given and various modifications, due to the reduced typhlosole, are described.

Studies investigating fertility decline in developing countries often adopt measures of determinants of fertility behavior developed based on observations from developed countries, without adapting them to the realities of the study setting. As a result, their findings are usually invalid, anomalous or statistically non-significant. This commentary draws on the research article by Moeeni and co...
