“Initially, we questioned: Why do the producers of meals enable scroungers to take meals from their mouths? Perhaps they’re stronger? However we discovered that many of the scroungers are feminine, and so we thought of the chance that females commerce mating for meals. This was our speculation, and, certainly, we discovered that that is the case,” lead creator and professor Yossi Yovel of TAU’s George S. Sensible College of Life Sciences mentioned in a information launch.
Yovel and his staff noticed that three or 4 months earlier than mating season, females would begin taking meals from a number of males.
“Then they finally mate with one of many males, the one with which they solid the strongest bond,” Yovel mentioned.

“The outcomes have been fairly clear,” Yovel added. “Females gave delivery to the younger of males from which they’d scrounged meals. The findings lend assist for the food-for-sex speculation on this species.”
Yovel and his staff additionally discovered the feminine bats hardly ever shared male mates, which authors of the research mentioned suggests “females select males to scrounge from based mostly on some type of particular person choice.”
Nevertheless, these preferences reportedly change relying on the 12 months.

“Going ahead, we intend to discover how these relationships evolve and alter over a few years,” Yovel mentioned. “We’d additionally prefer to learn how these interactions noticed in captivity play out in wild populations.”
