Lonnie D. Russellaucasus, Mount Elbrus 5642 m, and that of the Alps, Mont Blanc 4809 m. Yet, some of the highest peaks in the Caucasus are former volcanoes (Mount Kasbek with 5047 m, is one of them, in the core study region of this volume), whereas in the Alps, all summits are tectonic summits.

M. H. Johnson,C. A. Ziomek,W. J. D. Reeve,H. P. M. Pratt,H. Goodall,A. H. Handysidets, biologists, and data scientists is vital in expanding our knowledge of plant functional traits. This approach can unravel the ecological significance of these traits and elucidate their potential in guiding ecosystem management decisions.

Spermiation — the sperm release process: Ultrastructural observations and unresolved problemshighly differentiated cells through the excurrent duct system. At the time of release germ cells no longer should be termed . but spermatozoa or, simply, sperm. Sperm have attained virtually their final form at the time they are liberated; however, they are functionally immature and still lack the capacity to fertilize.

Fine structural features of Sertoli cellsSertoli (37) described these cells as ‘celluli ramificato’ and since 1888 (6) they have borne his name. Attempts have been made to introduce other names — sustentacular cells or sustenocytes, supporting cells, nurse cells — but the name Sertoli cells is generally accepted today.

Comparative aspects of acrosomal formation enzymes which lyse the oocyte membranes to permit entry of the sperm for fertilization. In some marine sperm the acrosome also ejects a filament which makes the initial contact of the sperm with the egg. Acrosome structure (1), and evolution (2), have been carefully reviewed recently, as well as aspects of acrosome formation and physiology (3).
