Effects of season, environmental temperature, size of dams, and age of breeder males on numbers of embryos obtainable from superovulated mice.

Experimental biology, 1985
Four factors were tested for their effects on numbers of embryos obtainable from mice injected with pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (hCG) to induce superovulation. The factors tested were: (1) season of year; (2) environmental temperature (in the range of 17.8-23.7 degrees C); (3) age of breeder male mice (in ...

Pedigree-based estimation of effective number of breeders in Iberian amphibians: the role of mating system in population status assessment

2017
Effective monitoring programs are required for early detection of population declines, especially in species with low effective to census population size ratios, in which genetic erosion will precede apparent declines in abundance. Calculation of effective population size (Ne) is thus crucial in genetic monitoring programs, but the accuracy of ...
