This preface is addressed to the reader who wishes to inquire into the prevailing concepts, hypotheses and theories about development of sensory systems and wants to know how they are exemplified in the following chapters. I believe that science is hypothesis and theory and that the growth and evolution of any branch of science can be measured by the degree to which its theories have been reified.

Soybean is considered a miracle crop because of its dual qualities, viz., high protein content and oil in seed. In India, the average area under soybean cultivation is 7.71 m ha and the productivity of crop is 1073 kg/ha with total production of 8.27 m t. Even though it is the cheapest high quality vegetable protein, we are yet to exploit its full potential. The excess use of chemical fertilizer spoils the structure of the soil. Therefore, use...

In any study of hermit crabs, correct identification to species level is of considerable importance. Whereas a number of identification guides to this group have been published during the last 50 years, none can be considered comprehensive enough for identifying all species inhabiting the Northeastern Atlantic Ocean and Mediterranean sea. The present guide is the first of its kind to provide taxonomic keys to all known species from these regio...
