Open questions (1) What are the spermatid-specific factors required for spermiogenesis and how do they control male fertility in mice? Can they be classified into different groups by their localization and function in spermatids? (2) What do these knockout mice tell us? Which factors are ...
What factors contribute to soil fertility? What factors affect the carrying capacity of an ecosystem? These factors may be biotic or abiotic. How does soil structure affect the characteristics of soil? What factors play a role in surface runoff?
The rightful place for the testis at birth is in the scrotum in order to provide the temperature differential essential for normal spermatogenesis. Appropriate screening programmes and early surgical intervention are the prerequisites to ensure optimal fertility in adulthood and a considerably lessened ...
The specific natural soil fertility values (0 = worst, 100 = best) were calculated from the soil units data160, using the methodology described in Bečvářová et al.161. Next, we operated with historical/geographical variables: The archaeological dating was obtained from the ...
