Forum 2.12 - Factors Impacting Island Diversity

10/23/2018

Central Question: What factors impact biodiversity on islands?

Guiding Thought Question: What factor do you think is going to have biggest effect on the biodiversity of an island? Why will that factor have such a large effect?

Today's Learning Objective: Students will learn about isolation, area, and equilibrium theories as they relate to island biogeography by examining case-studies in a map activity and the biodiversity of Iceland.

A change in the climate will effect it the most because a lot of the animals have a specific range that they can survive in

I think space will have the biggest effect on the biodiversity of an island, if islands are scattered then each fragment could have different ecosystem, elevations, etc. that can have animals and plants adapt differently.

I believe that how an island was formed will have the biggest affect on an island's biodiversity. If an island was connected to the mainland and already had lots of species to start with, it would be pretty biodiverse, but if an island formed out of the water, it would take much longer to reach that level of biodiversity if it could even reach that point.

The biggest effect could be the rapidly changing of the islands geography. The changing of the geography could rule out the weakest of the species and only the species who are adapted to survive these changes would survive.

i feel like the age of the island will effect the biodiversity the most

The weather/climate will have the biggest impact on biodiversity because if an area has a higher mean temp then there will be more biodiversity on the island (species energy theory)

The climate of an island will be the biggest determining factor of the biodiversity of said island. This is because the limited range of the island itself means that practically all of the biotic factors will be adapted to the same specific climate, limiting the biodiversity.

The biggest factor that effects biodiversity is certain isolation items like a mountain or river or a new island where the species are separated and have to adapt to their own environments away from the others so over time they could look every different and then they would no longer mate with each other

Climate will have the biggest effect because it will control the types and adaptations of the animals that live there.

Variation of trees. This factor will have the biggest effect on the biodiversity of an island because it will be home to many animals and will provide food also for the animals as well.

Biodiversity is effected by changes in the environment’s climate; climate change has a large impact because if the animals on the island are unable to adapt, then they will die off. Only the strongest will survive, allowing natural selection to determine the future biodiversity of the island.

Factors that can have an impact on islands are flooding, rain, a sinking island.

I think the changing climate would be the biggest affect on island's biodiversity. It would eliminate certain species and only the species that can adapt to the change in temperature would survive.

The way the island was created and changes over time is going to have a big impact on biodiversity. If an island was made with little to no resources then it will not be able to home more diverse species than if it had a variety of resources. In order to see diversity in a location they must have livable conditions.

A change in temperature (global warming/climate change) would most likely have the greatest effect because animals are adapted to survive in their current habitat, so a drastic temperature change will require them to adapt to the new environment, move to another environment that fits their needs, or die

The biggest factor that will affect biodiversity in an island is climate change. Since islands are restricted to certain animals who cannot swim or fly if they don't adapt to their new environment they will die off.

How they were formed can determine biodiversity. Glaciers can melt into lakes and the older they are the more likely they will be diverse. Man made places will less biodiverse. If an island was recently created it will probably have no plants or animals, but if it split off from the mainland it will have the same species unless the island has significantly changed from the mainland.

The amount of energy that the island receives

Climate will have a big impact because it affects how the animal evolves and adapts to their environment.

Hannah Cochran

space on the island would determine biodiversity because there might not be enough space for multiple species to exist and evolve.

Max Lambert

The amount of time the island has been in existence (midway between emergence and submergance)

Avery Wagoner

Isolation. Their range is greatly limited and they have diverse variety of ecosystems that animals have to adapt to

The biggest factor of determining the biodiversity of an island is climate because if an island has a warm and sunny climate then it could sustain more life.

The amount of rain on the island would effect biodiversity because there are more animals that can survive when there's more rain then when there isn't

I think the biggest factor on island diversity is the fact that islands are so isolated. Since most island animals cannot migrate off of the island, they have to adapt to their surroundings, and it causes them to have very different adaptations from animals on continents.

I think climate would have the biggest climate on biodiversity on an island

The biggest effect of an animal living on an island is space to move and live and how the climate will affect the animal

the rise of sea level causes less resources and of diversity in a smaller area

Eisenhower

Climate change. Climate change would affect the food the plant life and the animals life. Everything about biodiversity would be affected by climate change. Animals could lose food or water source as well as a home

I believe that the weather and climate have the biggest impact because animals have a limit to what they can and can't survive in

climate has the biggest effect on biodiversity because not every species can survive in certain climates

Forget

I think that space plays a big part in that. If the island was bigger then the animals would be able to move around and/or migrate
