Evolab Guppies
Exercise 1: Assessing Color Variation Among Males in Guppy Populations
Upper West Stream Male # | Spot Brightness | 1 | 19 | 2 | 13 | 3 | 13 | 4 | 13 | 5 | 16 | 6 | 14 | 7 | 17 | 8 | 16 | 9 | 14 | 10 | 16 | 11 | 17 | 12 | 18 | 13 | 13 | 14 | 14 | 15 | 17 |
Notes:
* Rivulus species also found in stream * Female guppies have no spots * Small amount of Rivulus compared to guppies * Adequate amount of food for the guppies
Histogram:
Hired Assistant:
Upper West: This is a similar distribution to the one I made. Although it is a smaller sample the distribution is similar.
Upper East: No predators large population.
Meir Creek: Two different predators no guppies, large amount of food.
Lower West: Two different predators large population of guppies small amount of food. Lower East: Large guppy population one predator adequate guppy food available. 16. Upper West: This stream had a large population of guppies in which the majority of the populations were male. These males all showed a high level of spot brightness. There were few predators in this stream and an adequate amount of food. The water quality is a grey brown on the program. Upper East: This stream had a higher population of guppies with a varied amount of male and female. There is still a high proportion of bright spotted males however these males are not as bright as in the upper west. There are no predators in this stream and an adequate amount of food. The water quality is a grey brown on the program. Meir Creek: This area had no guppies present. There is however two different predatory species and a high abundance of guppy food available. The water quality is a grey brown on the program. Lower West: This stream has a lower proportion of bright males compared to the upper streams. There are also two different predatory species and a smaller amount of guppy food available. The water quality is a dark blue
