Sex And The Single Guppy

1.The different colors of the guppies depends on where they live in the stream. It also depends on what stream they are in, and how many predators are in that certain area.

2. The fish we chose was called Poecilia reticulata. Its origin is Brazil, and its average size is about 3.5 centimeters long. It has many splotches of bright colors, including yellow, black, green, red, and white.

3. The predator we chose is called Dermitator Maculatus, and its common name is the fat sleeper. It's origins are Southern North America, the Bahamas, and Latin America.

4. The type of habitat the guppies live in depends on the amount of predators because sometimes guppies can live in an environment protected by a dam, and this dam prevents the predators from getting to the guppies.

5. John Endler is a an evolutionary biologist. He studied wild guppies in Trinidad.

6. Pool 1: The guppy coloration is brightly multi-colored with large spots.
Pool 2: Medium coloration on body and tail, with medium-sized spots.
Pool 3: Drab coloration, very small spots concentrated near tail.

7. I think guppies have different coloration so they can attract mates. I also think it's so, in different environments, they will always find some place to blend in with the environment so predators have a lesser chance of seeing and eating it.

	% of Brightest Guppies (10 generations)	% of Bright Guppies (10 generations)	% of Drab Guppies (10 generations)	% of DrabbestGuppies (10 generations)
Trial 1 Guppy: Even Mix Predators: 30 Rivulus	57%	25%	14%	5%
Trial 2 Guppy: Even Mix Predators: 30 Rivulus, 30 Acara	4%	61%	35%	0%
Trial 3 Guppy: Even Mix Predators: 30 Rivulus, 30 Acara, 30 Cichlid	0%	11%	7%	82%
Trial 4 Guppy: Mostly Bright Predators: 30 Rivulus	64%	30%	5%	2%
Trial 5 Guppy: Mostly Drab Predators: 30 Rivulus, 30 Acara, 30 Cichlid	0%	0%	0%	100%

8. Predators influence guppy coloration because they see the brightly colored guppies more easily than the drab guppies.

9. I think my hypothesis was correct because the results show that in bright environments, the bright guppies thrived, and in drab environments, the drab ones thrived.

10. It means that the male guppies get eaten before their mates, so their mates have a lesser chance of being eaten because of the males.

11. I think different colored guppies live in different parts of the stream because different part of the stream have different colorations, just like the guppies.

12. I think that the drab guppies would die out, since their populations were the most when there were lots of predators.

13. I think that the bright guppies would die pout, since their populations were the highest when there weren't a lot of predators.

Biodiversity

1. A lot of species' existence depends on a different species. If one species becomes extinct, that could lead to the extinction of 2 or 3 others. However, if we preserve a species, it could make other species healthier and possibly keep the number of that species up, or even increase it globally.

2. Habitat destruction leads to loss of species, and loss of species can lead to loss of more species, and so on. It will eventually lead to loss of many more species than just one, and min many other habitats and environments as well.

3. Some people have structure their lifestyles and cultures around nature. Getting rid of biodiversities may mean these people must make a whole new culture or lifestyle because their old one is gone.

Article/Video Thoughts

In the article, it says that the oil is becoming less dangerous because there's less of it, but I'm not so sure about that. See, I think the oil is still just as dangerous, there's just not as much. And, in my opinion, I don't think it's even going away completely if we use chemical dispersants, because chemical dispersants just break the oil up, they don't make it go away. And even if it is going away, I still don't think it's becoming less dangerous, because it's still oil, and it's still hurting our oceans and the animals in and near it.
