In this pack of BIO 315 Week 2 Discussion Question 3 you will find the next information: Describe the three main types of predator defined in ecology. How does an understanding of fitness‚ abundance‚ and foraging behavior help us understand predation? How does environmental patchiness or fragmentation affect predator Deadline: ( )‚ Biology - Ecology and Environmental Science I urgently need help on this course and many other courses. Am almost to the end of week two and haven’t been able to

You will find this information in Chapter 24.) 8. Predation is a term that you probably already know. Can you give examples of some predator-prey combinations as listed below?

responses for years or decades (Estes‚ 2011). Unfortunately‚ when responses are eventually recognized‚ it is often too late to reverse the damage. From the definition of trophic cascades‚ it is clear that the general system of herbivore control is predation; therefore‚ an absence of apex predators may allow herbivores to expand to the point of vegetation depletion (Hairston‚ 1960). Furthermore‚ a substantial decline of apex predators can result in a shift from top-down to bottom-up driven ecosystems

specific community: they may assist in pollination help regulate populations. Foundation species affect the community’s habitat to benefit other species. 3. Species interact with each other in these different ways: interspecific competition‚ predation‚ parasitism‚ mutualism‚ and commensalism. 4. As environmental conditions change‚ one species may be replaced by other groups of species. This gradual change in the composition of species in a given area is called ecological succession. 5. A

Wasp Mimicry Mimicry‚ essentially‚ is some type of resemblance between two unrelated organisms which improves the organisms’ chances of survival against a 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

Within our food web of Salt Water Marshes‚ located specifically in Virginia‚ there is a symbiotic relationship between the American Alligator and other organisms whose survival is dependent on the water they live in. During dry seasons‚ gator holes fill up with water‚ and could be one of the only locations with water. All the organisms

animals in the grasslands. This loss of top predators in the grassland is causing major economic and ecological disruptions. Due to this disappearance baboons have found a new territory to take over and become more aggressive as a result of no predation. Also the baboons are able to do night time hunting‚ raiding farms of livestock and vegetation. That being direct effects of disappearance of animals and the indirect effects include exchange of diseases transmitted from baboons to humans‚ and farmers
