ground-nesting birds. I hypothesized that cryptic eggs would reduce predation rate‚ therefore less cryptic eggs should be found. I created a simulation in which eight students randomly “laid” 96 eggs in a predetermined area‚ and seven predators hunted eight eggs each. The predators did not see the eggs being laid‚ and were given an egg quota so that all the eggs were not found. Also‚ they were directed to pick up the first eight eggs they noticed and not look for a particular kind. Half the eggs were white

common predator. This resemblance can be seen in warning signs‚ typically visually with colors and patterns‚ but organisms can also have resemblances in smells and many other traits that deceive the predator into believing the insect is something that it’s not‚ saving the insect’s life. Mimicry typically involves three things: a model‚ a mimic‚ and a selecting agent (Boppré et al). Mimicry is affected by natural selection (Kikuchi et al). When an organism survives and deceives its predator‚ then those

Persuasive Essay I bet you think predators are horrible! But they are very helpful. Without predators‚ there wouldn’t be as much as we have now. Predators help keep prey population in balance. Without them there would be too many animals and no space to eat or to run. There would also be health problems. So I am going to tell you good‚ positive things about predators. Predators help control the population of the prey in the area. Smaller prey populations can be healthier because disease can

Benny Ndegwa April 2nd 2013 Mr. Metoyer Lab Biology The Colorful Guppy Lab Report Problem: What is the relationship between the brightness of the guppy and their predators and mates? Hypothesis: If predators attack the guppy populations‚ then the drab guppy population will increase due to high predation. Materials: 1. Guppies 2.

An Ecologist that has spent his entire life devoted to how the environment has determined the development of life‚ publishing books and being senior scientists at the Smithsonian Tropical Research Institute in Panama. Colinvaux points out certain pieces of the Tyrannosaurus rex that has allowed him to formulate whether the Dinosaur is a predator or scavenger. His research and opinions

The newfound predators that hunt by speed and eyesight will be salient‚ or prominent‚ to the squids‚ creating a new environment. These new predators will act as selective forces by changing the environment of the squids causing it to be a more dangerous place to inhabit. This will affect the squid’s ability to avoid harm brought about by the predators. They must learn to adapt their defense mechanisms in order to better protect themselves from these new effective predators. In order to

Giraffes This research paper is about one of the most fascinating animals I have ever done researched about. This animal would be giraffes. I have researched and found a lot of interesting facts about giraffes. Some of the facts I found are‚ giraffes habitat‚ what they eat and more. Giraffes only live in one continent. This continent is Africa. Giraffes are mostly in the countries of Chad and South Africa. Giraffes need a lot of room to roam ‚ so giraffes enjoy living in the savannas

effects on the guppy population and their color distribution depending on the predator that lives in their environment. Endler wondered how the trade-off between attracting mates and affecting predators affects the coloration in male guppies. In pools that had few predator species‚ male guppies tended to be brightly colored‚ whereas predators are causing guppy populations to become drabber. This occurs because the predators are preying on the most brightly colored individuals and eliminating them from
