Here we report that females can incur high energetic costs as a result of discriminating among potential mates.
Females that spent more time on the territories of high-quality, high-activity males displayed greater energetic expenditure on mate choice, lost more mass, and showed a trend towards producing smaller follicles. Choosy females also appear to face a reduced probability of survival if El Niño conditions occur in the year following breeding. These findings indicate that female choice can carry significant costs, and suggest that the benefits that lek-mating females gain through mating with a preferred male may be higher than previously predicted.
To all the girls....Sorry.
This is just an excuse to show you the Public Library of Science (PLoS)
Here's the story I was going for:
High-Yield Hydrogen Production from Starch and Water by a Synthetic Enzymatic Pathway
The future hydrogen economy offers a compelling energy vision, but there are four main obstacles: hydrogen production, storage, and distribution, as well as fuel cells.
