What would happen to brightly colored guppies placed in a stream with many predators?

Develop your own hypothesis about guppy coloration. ... In pools with many predators, guppies will have a drab color because it improves survivability.

How does the presence of predators affect guppy coloration?

We've seen in our simulations that the more brightly colored a male guppy is, the more likely he will be seen -- and eaten -- by a predator. In a simulation or in the wild, where predators are plentiful, male guppies become increasingly drab over generations, pushed by predation pressure toward greater camouflage.

What do you predict would happen if you placed a population of guppies that had mostly brightly colored guppies into a stream with a lot of predators?

The population of bright guppies would increase due to there being no large predators. Since there are no predators there is more mating and reproduction, bright coloured guppies would have the high population.

What are the predators of a guppies?

Guppies have many predators, such as larger fish and birds, in their native range. Some of their common predators in the wild are Crenicichla alta, Anablepsoides hartii, and Aequidens pulcher.

Why are guppies brightly colored?

U.S. scientists say they have discovered why male guppies, the most fertile member of the fish tank, are so colorful. The University of Illinois researchers, working in Trinidad, say the answer is genetic, with the vibrant colors used to attract females.

How is the colorful bright coloration helpful to the male guppies?

Abstract. Although conspicuous visual sexual signals, such as bright colors, in males serve to attract females in numerous species, they may also attract the attention of potential predators and thus may be costly in terms of increasing individual risk of mortality to predation.

How does the presence of predators affect guppy spot coloration and size?

Increasing predation is also associated with a reduc- tion in color patch size, primarily of the pigment colors (black, red). All of the changes make guppy color patterns less conspicuous at high, compared to low, predation intensities (Endler, 1978).

What caused the trends in the coloration of the guppies?

As turbidity decreases in the pools Endler collected guppies from, the number of predators decrease and the number of bright colored guppies increases. Therefore, the trends in the coloration of guppies is caused by the turbidity of the water.

Which of the following would you predict would evolve in guppies taken from streams with predators that key in on prey color and put into streams lacking predators?

Which of the following would you predict would evolve in guppies taken from streams with predators that key in on prey color and put into streams lacking predators? Guppies would evolve to have females prefer even more colorful males.

Why are guppies a good species to study if you are interested in documenting evolution in natural populations?

Researchers found that guppies introduced to a low-predation environment adapted to their new environment by producing larger and fewer offspring with each reproductive cycle.

What observations did Endler make about guppies spot brightness in the streams and in the presence absence of predators?

Endler's Discovery

Males from one pool sported vivid blue and orange splotches along their sides, while those further downstream carried only modest dots of color near their tails. Endler also observed differences in the distribution of guppy predators, and in the color and size of gravel in different stream locations.

How might a change in the environment affect natural selection?

If the environment changes rapidly, some species may not be able to adapt fast enough through natural selection. ... An invasive species, a disease organism, a catastrophic environmental change, or a highly successful predator can all contribute to the extinction of species.

How does a guppy get pregnant?

In most species of fish, the male fertilizes the eggs after they are laid. However, guppy eggs are fertilized by the male while they are still inside the female's body. The eggs develop into tiny miniatures of their parents that are born alive and ready to fend for themselves.

Do guppies eat their babies?

After giving birth to their offspring, guppy fish will not exhibit any parental care and if left in the same aquarium with the fry, they will mistake them for food and eat them. ... A further explanation is that by eating her own fry, the female guppy is replenishing her fat storage.

Can guppy live with Betta?

So to conclude this article: yes, guppies and betta fish can live in the same aquarium. You will have a bit more work feeding your betta separately and you will also need to purchase live plants, but it is doable.
