So, yesterday's election turned out rather poorly for Democrats.
On a completely unrelated note, I wanted to draw attention to a paper published in Biology Letters that investigates the ejaculatory strategies of male flour beetles of the species Gnatocerus cornutus. As in many species, G. cornutus males engage in pre-copulatory sexual selection, where males fight, and the winners get privileged access to mates. The researchers, at Okayama University, find that the losers of these fights appear to shift to a strategy that focuses more on sperm competition, through increased "ejaculatory investment." Winning a fight has no effect on the number of sperm "transferred" during a copulatory event. However, losers show two effects that indicate a strategic shift: they are less aggressive towards other males, and they increase their sperm transfer by nearly two-fold.
By the fifth day after losing the fight, both aggressiveness and sperm-transfer levels return to normal, so we can expect a return to Republican levels of "transfer" sometime this weekend.
