species interactions

This week in Practice and Reinforce” the focus was on succession, so the forum this week will focus on species interactions. You saw just a few examples of adaptations that plants and animals have developed to protect themselves from predators. Your task for this forum is to seek out your own example of an adaptation that benefits a species of your choosing and present it to your classmates. This could be any type of animal with any adaptation covered in the lecture and reading materials: Mimicry, chemical defense, camouflage, warning coloration (just to name a few).

Research your chosen animal and create a new discussion post, addressing the following aspects:

Use the name of your chosen animal as the post title.

Points will be deducted for duplicate entries (unless the time stamps on both posts are very close together, suggesting they were being written at the same time).

Present your animal and your adaptation.

Discuss native habitat, other species the animal typically interacts with including predators and competitors.

Think about community interactions and co-evolution as you explore your chosen species.

Discuss how the animal’s adaptation helps them survive, as well as how its predators/competitors have evolved in response to this adaptation.

Include a picture to in your post.

(or at the very least a link to a site that has an image).

To receive full credit, you must:

• Write in complete sentences that are thoughtful, well written, and free of typos.
• Address all parts of the forum topic.
• Use vocabulary presented in the learning materials appropriately.

An example of how the discussion should look like

rctic wolves have many adaptations for living in the cold. One of them is size. The bigger the wolf are, the more warmth. Arctic wolves have two layers of fur. The outer one is thicker and conserves heat while the inner one is a waterproof layer, sort of like a scuba diving suit. That way they can survive snow and the cold, while the thickness and the ability to conserve warmth decrease during summer. Arctic wolves have smaller ears than other wolves since that also helps them conserve heat. The paws on a wolf are padded with fat to give them a grip on snow and ice and also to protect them from the cold ground. Arctic wolves must travel over large distances to hunt their main prey, musk ox and caribou (or reindeer). They will prey on smaller animals, such as arctic hares, arctic foxes, lemmings, and waterfowl. Sometimes, they will scavenge the leftover prey of a polar bear. Arctic wolves are carnivorous, and since there is such little plant life in the arctic anyway, they only eat meat.
