Forum 2.12 - Factors Impacting Island Diversity

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.

The biggest factor that will have affect on the biodiversity on an island is the potential weather that can occur. For example if an island has regular hurricanes the animals and plants will have to have adapted to the weather. So if this limits the amount of animals that can live on the island since they will have to have be able to live in the area with the weather.

I think separation has the greatest effect on the biodiversity. The separation allows for species to evolve separately, increasing the likelihood of diversity.

I think how long the island has been separated will effect it most

The biggest factor is natural disasters. An island can be so small that any kind of storm can wipe the entire biology of the island out.

The biggest effect on island biogeography is going to be the isolation. This is because creatures surrounded by a habitat drastically different from their own will have difficulty leaving their habitat.

Climate, it affects the plants and other flora that are able to grow there. The flora that grows there may determine the fauna that reside there as well.

A big factor could be potential natural disasters

The time of separation cause island biodiversity because the longer the animals are separated the more diverse they will become through the adapted species And the isolation prevents them from leaving

Limited space and resources will impact how biodiverse an island can be because there is not enough space to have many different ecosystems and species in a small, isolated area.

The biggest effect on an island's biodiversity is the weather/climate of the island, because if it is prone to large storms, the biodiversity of the island is going to be very limited. Also, if the island is extrodinarily cold all year around, the more likely to have less diversity.

I think the size of the island will effect the biodiversity on the island because if the island is small then not a lot of species can live on it so it will decrease the biodiversity on the island.

climate is a big effect on biodiversity because when the climate changes and if the animals can't adapt to it they will start to die off. Also the polution in the water can kill the animals if it is dirty

I think the biggest factor that is going to effect the biodiversity of an island is separation because it allows for species to evolve on their own, which leads to the increase of diversity from other species in other regions.

climate will have the biggest effect on biodiversity because plants and animals will be adapted to the climate they live in

Probably an islands climate. If it is has large storms, the biodiversity of the island is going to be very limited. Also, if the island is cold all year around, the more likely to have less diversity.

I think the biggest factor that will have on an affect on a island would be climate. Climate controls the growth of plants and what plants are able to survive there. This also controls what animals are on that island.

Island's isolation is a big factor. As animals stay put in the island for a long period of time, they adapt more and more to their environment and climate. This prevents them from easily moving back to the mainland since they are so specifically adapted.

the biggest factor is probably the ocean because it could cause many different types of weather that affects the animals that can live there and also that animals cant always come to the island or leave the island depending on how close the island is to the mainland depending on how well the animal can cross water

The biggest effect on a islands biodiversity is climate because the climate of the area will effect what plants and animals are in an area.
