Changes in wetlands

Hurricanes can increase competition for pelicans.

• Make pelican and other animal's prey flee or die.
• That increases competition for food.

Increased competition

• When there is increased competition, pelicans will fight gulls for food.
• It is resolved by one of them being injured or fleeing.

Pelican mutualism

• Increased competition in the wetlands results in a mutualistic relationship
• It is between the pelican and cottonmouth snake.

Pelican mutualism

• Pelicans will leaves a little fish for the cottonmouths.
• The cottonmouths protect the pelicans from their predators.

Pelican Conmensalism

• Pelicans have a conmensalistic relationship with gulls.
• The gulls will steal fish out of pelican's mouths.
• The pelican isn't harmed because it can get more fish.
• This relationship is caused by increased competition.

Pelican commensalism

• The pelican isn't harmed because it can get more fish.
• This relationship is caused by increased competition.

Pelican Parasatism

• Pelicans have a parasitic relationship with worms.
• The worms can infect the pelican's gut and possibly kill them.
• The worms can feed on the pelican's scraps.

Pelican Adaptation

• Pelicans have webbed feet that help them swim faster.
• That helps them not be killed by snakes and alligators in the water.

Secondary Succesion

• A hurricane can wipe out a wetlands ecosysten
• But thanks to secondary succession we can get it back.

Secondary succession

• First mosses and small grasses begin to grow.
• Then small trees start to grow

Secondary succession

• Eventually the trees grow, the animals come back.
• The ecosystem is back!

Wetlands biodiversity

• There is lots of biodiversity in the wetlands.
• That helps secondary succession because there is plenty of food .

Why humans come to wetlands

• There is lots of wood for building and selling.

Why humans come to wetlands

• Lots of food to eat
• Lots of water
• Can hunt animals and sell them.

How humans affect wetlands

• Cause pollution for air and water by littering and smoke.
• Bring in invasive species like the purple loosestrife plant.
• Erosion of the land

How humans affect wetlands

• Humans can affect wetlands in a good way.
• Humans will breed and help endangered animals.

How humans affect wetlands

• A negative one is they erode the shorelines.
• That makes the wetlands become smaller and smaller.

How can you help?

• You can help stop erosion.
• There is an easy way for you to help.

How you can help?

• All you have to do is buy and plant trees on the coastline.
• Sandbags will also help.

How you can help?

• It may take money and time but it will be worth it to save the wetlands.
• So please, give as much money as you can for the planting of trees to help the wetlands.
