Predation

Definition

noun

A form of symbiotic relationship between two organisms of unlike species in which one of them acts as predator that captures and feeds on the other organism that serves as the prey.


Supplement

In ecology, predation is a mechanism of population control. Thus, when the number of predators is scarce the number of preys should rise. When this happens the predators would be able to reproduce more and possibly change their hunting habits. As the number of predators rises, the number of preys decline. This results in food scarcity for predators that can eventually lead to the death of many predators.

Re: Eliminating Predation via Selective Breeding

It may be possible. I am not a fish breeder, but behavioural changes have been made in a few generations in other species. The example that comes to mind is the breeding of tameness into the silver fox. http://en.wikipedia.org/wiki/Domesticated_silver_fox

Eliminating Predation via Selective Breeding

Greetings. I'm not sure this is the right section to post this, but if not correct, I would ask that the mods relocate. A well-known breeder claims that he has, "bred all predatory fry eating, out of his female guppies, through a few generations of selective breeding." I'm no scientist, bu...
