Understanding River Temperature Dynamics: Effects on Ecosystems and Wildlife

This article examines the definition of temperature and its impact on river ecosystems. River temperatures typically range from 4°C to 25°C, influenced by environmental factors such as tree cover and waste disposal. High temperatures can increase fish metabolism and decrease dissolved oxygen levels, while low temperatures may hinder food growth and availability for aquatic and terrestrial animals. Solutions like planting trees for shade and halting waste dumping are suggested to manage temperature imbalances. The article also provides formulas for converting between Celsius and Fahrenheit.

  1. By: Nick Petraccione, Lance Armour, Lucas Maloney, Spencer Moran Temperature

  2. Definition • A measure of the average kinetic energy of particles in a sample of matter.

  3. What is the normal range of temperature in rivers? • Rivers usually stay at a temperature between 4°C - 25°C.

  4. What contributes to the temperatures rise/fall? • The surrounding environment • Greater amount of trees surrounding the river will expose the river to less sun. • Companies dumping waste into the environment.

  5. Disadvantages when the temperature is too hot • When water is too hot: - Fish become more active at feeding because of higher metabolisms. - Food sources become scarce because of the higher activity in the water. - Dissolved oxygen levels will decrease.

  6. Disadvantages when the water temperature is too cold • When the water is too cold: - Food becomes harder to find because it wont grow as well. - Food becomes scarce for animals living on land.

  7. Ways to alleviate any imbalance in temperature • If the water is too hot, planting trees would introduce shade to the area. • Stop any dumping of waste products if that is the problem.

  8. How to convert between Celsius and Fahrenheit? • From Celsius to Fahrenheit: F= (C x 9/5)+32 • From Fahrenheit to Celsius: C= (F – 32)x(9/5)
