Guppy Simulation

1. I think that guppies are so colorful to attract more mates, because without the color there wouldn't be enough mating so the population would go down.
2. Common name: Guppy or millions fish. Scientific name: Poecilia reticulate. Origin: Venezuela. Size: 1.4 inches.
3. Common name: Blue acara. Scientific name: Aequidens puncher. Origin: Trinidad and Latin America. Size: up to 7 inches.
4. It could affect the predators because they are sometimes dams that are upstream preventing the movement of predators to upper streams and confining them to the lower sections. A guppy population above these dams would most likely have little to no predators.
5. John Endler was a evolutionary biologist. He studied wild guppies in Trinidad.
6. The three areas we chose were,
A. the dam, brightly multicolored with large spots.
B. the Quare river, medium coloration on body and tail, with medium sized spots.
C. a shallow pool, drab coloration, very small spots concentrated near the tail.
7. I think that guppies are different in color depending on where they are in the pool because of predators. If there are more predators the guppies might be a little darker than the ones without many predators in their pools. Although some guppies mightn't care about the predators and have the brightest colors they can to attract a mate.

Trial 1 Guppy: Even Mix Predators: 30 Rivulus
Trial 2 Guppy: Even Mix Predators: 30 Rivulus, 30 Acara
Trial 3 Guppy: Even Mix Predators: 30 Rivulus, 30 Acara, 30 Cichlid
Trial 4 Guppy: Mostly Bright Predators: 30 Rivulus
Trial 5 Guppy: Mostly Drab Predators: 30 Rivulus, 30 Acara, 30 Cichlid

8. If the guppies were to bright or to drab they would be eaten and those population would reach zero.
9. Yes and no. I thought that the brightest would die out and get eaten which they did. I also thought the drabbest wouldn't get eaten, but they did. Eventually the drab all were atenolol and there was only brightest left.
10. Male guppies live closely between their predators, and their females that they will mate with.
11. I think the colors all depend on the predators and what type of area they are in.
12. I think that if they were mostly drab with few predators they would start to thrive because of the lack of color and predators. Without to much color the few predators wouldn't really notice them very easily.
13. If there were brightly colored guppies with lots of predators the population would either be in an even balance or go down. It could be even because without he bright colors the guppies would attract more mates. It could go down because of the bright colors they could get eaten easier.
