- Salmon: olfactory snobs. But this means even small amount of pollution in streams can have huge effects on their populations.
- Sex in space? Sure, why not. Reproduction in space? No. At lest, not at zero-G. Particularly if you’re a Zebrafish.
- Is it time to look past sexual selection? Perhaps evolution and mating systems are really linked via social selection (of which sexual selection may merely be a special case).
- Some birds may use the calls of predators to get their mates to pay attention to their own calls, much like humans co-opting scary movies on date-night. But do they casually put their wings around their mates while they fake a yawn?
