What is Invasive species

Hello! I’m a Mr.Science!

Today, I want to introduce about Invasive species!

What is Invasive species?

-> Exotic that spreads into natural or semi-natural habitat, causing a major change in the habitat and how it functions.

How do they get there?

-> Accidental introduction

-> Purposeful introduction and accidental spread

-> Purposeful introduction and spread

-> Expanding range because humans have changed the area 

Bad Result

-> Out – Compete native species

-> Cause disease in native

-> Prey on native species

-> Degrade habitats – erosion, loss of soil

-> Change natural processes (natural fire protection)

Asian clams, for instance, were introduced to the coast of the Amefias. In these areas, they don’t have natural predators. They also reproduce quickly. As a result, Asian

Clams are threatening to overtake many coastal areas.

They do so by taking over the space and using the nutrients that local species would normally use.

Clams consume plankton for nutrients-the same foods that many smaller fish eat.

Thus, lacking nutrients, many fish species have died in areas invaded by the clams.
