Animal Species for Developmental Studies | Volume 1 Invertebrates. Questo articolo non è disponibile.Animal Species for Developmental Studies | Volume 1 Invertebrates

This volume comprises normal tables (description of normal development) for protozoa and invertebrates widely used in developmental biology studies. The species chosen reflect their advantages for laboratory studies, the information avail­ able, and their availability for experimentation. Chapter 11, which contains the normal tables for the starfish Asterina pectinifera, was written specially for this edi­ tion, which is the invertebrate section of the revised and augmented translation of Ob"ekty Biologii Razvitiya published in Russian in 1975 as a volume in the series of monographs Problemy Biologii Razyitiya (Problems of Developmental Biology) by Nauka Publishers, Moscow. The description of every species is preceded by an introduction in which the advantages of working with the particular animal are stated and the problems stud­ ied (with the main references) are outlined. Data are also provided on its taxonomic status and distribution of the animal, and conditions of keeping the adult animals in laboratory. Methods of obtaining gametes, methods of artificial fertilization, meth­ ods of rearing embryos and larvae, and tables of normal development are also given.
