The Journal Impact Factor (JIF) has been heavily criticized over decades. This opinion piece argues that the JIF should not be demonized. It still can be employed for research evaluation purposes by carefully considering the context and academic envi

Sweepstakes Reproductive Success in Highly Fecund Marine Fish and Shellfish: A Review and Commentary
Publikováno v:
Bulletin of Marine Science. 87:971-1002
Most marine animal species are very abundant, relatively long-lived, and late-maturing, with highly fecund adults adapted to spatially and temporally fluctuating ocean environments. Adults typically produce millions of small eggs that develop rapidly

The effective number of breeders (N b) for a cohort of progeny can be estimated from an excess of heterozygotes that arises in progeny produced by finite numbers of parents. In principle, N b is a simple function of the standardized deviation (D) of
