Default Oophaga selecting mates due to color

During many readings about Oophaga, it is known that they have the rods and cones in their eyes needed to see color, which is how they choose mates of the same morph for breeding;

This brings into question the recent Rio Branco Pumilios. How is the population so diverse if only like colors will breed with one another? Is that the reason they have remained such a diverse population?

Discussion...

Yeah, I had the same thoughts about Uyamas and the different colors of the same morphs of sylvaticus/histrionicus.

Does the research indicate that they won't breed with different colors, or just prefer the colors closest to theirs?

When I'm in a bar at last call (in other words there are few choices in mates), the rods and cones in my eyes often result in choosing a less than ideal specimens.

Mainly because sexual selection isn't going to be the same for every frog, and even if it was the alleles for other colors is still there. Every red female isn't going to choose red males, some may want orange or yellow, etc. but if 2 reds do breed, they could possibly still carry the alleles for yellow or what have you. There are other factors at play but those are the main reasons.

Someone posted this on the boards recently:
Unfussy Female Poison Frogs Just Go For Closest Male – Phenomena: Not Exactly Rocket Science
This indicated that pumilio female darts go for whatever they found first (i.e. the closest calling male). It would appear that "looks" doesn't really have much to do with their choice then. Which I guess makes sense given that inter-species hybrids (in the tinctorius group at least), can happen quite easily in captivity, even in frogs that have different colors and calls (such as leucs and auratus).

I think for frogs, muscle is more important than brain or look.... LOL...

Just grabbing the closest available mate, huh? No matter how skanky? Sounds a lot like the courting requirements of a roommate I had once!
hypostatic and GP dynamite like this.
