Roach have a "lek-like" breeding system (Wedekind 1996) in which a number of males occupy the spawning site, and females enter the area specifically to spawn with the competing males.
Hence, we counted the number of male approaches until each female spawned, with the expectation that this inverse index could reflect mating preferences of these intrinsically passive medaka females (that is, fewer approaches, more preferable).
If you spawn with the rocket launcher and you see someone else spawning in the distance, immediately shoot them twice and they will most likely die (75 +75 = 150, which is more than 100 health).
McPhee mines nuggets from scientific papers, histories -- after murdering Lincoln, John Wilkes Booth got across the Potomac and Rappahannock rivers at the height of the spring spawning run with the help of shad fishermen -- colonial newspapers, biographies and memoirs.
Depending on the size, the average female may lay up to 195,000 – 8 million eggs during spawning season, with the average female laying 2.3 million eggs.
How corals tune their spawning behavior with the phases of the moonlight was an unanswered question for decades.
We tested several concentrations of PF-670462 and performed the circalunar spawning assays with the lowest concentration still exhibiting robust effects on circadian clock molecular oscillations.
