What affects species distribution
What affects species distribution Environments

  • Some of the things that can affect species distribution are, the abundance of the species, the density of others species in the same environment, water acidity, dissolved oxygen content, food chain, disease, pollutants, and human activity.


Abundance of the species
Abundance Of The Species Environments

  • The abundance of the species can affect the density the species can live in, for example some species with a large abundance prefer to live in groups so a large number can live in a certain area, but others prefer to live alone so few live in an area.


Density of other species
Density of other species Environments

  • The density of other species can affect distribution as well. For example if a large amount of plankton live in one area, whales may be more tempted to stay in that are.

Water acidity
Water Acidity Environments

Water acidity can affect species distribution if an area is too acidic. If the water is too acidic the fish have trouble breathing and can die.

Dissolved oxygen
Dissolved Oxygen Environments

  • Dissolved oxygen affects species distribution because in an area with low dissolved oxygen the fish can’t breathe so they die.

Food chain
Food Chain Environments

  • The food chain can affect species distribution as well. If a predator lives in an area, the other species may be thinner due to the predators feeding.


Disease Environments

  • Disease can affect species distribution by killing off the fish and other aquatic organisms. If one animal gets sick it can quickly spread to other organisms

Pollutants Environments

  • Pollutants can affect species distribution because, high levels of toxic material will kill fish and other aquatic organisms, some materials such as oil, will poison the water making it unable to swim or live in.


Human activity
Human Activity Environments

  • Humans affect species distribution as well, if too many people fish in a single spot they can completely wipe out the fish that live there, also movement in the water can scare some fish away.

Conclusion Environments

  • There are many factors that can affect species distribution, some natural and others manmade. The ones that are manmade such as pollution and fishing can easily be controlled, please do your part to keep them healthy.
