Algal blooms

Definition

Algal blooms are rapid increases in the population of algae in aquatic systems, often resulting in discoloration of the water. These blooms can be influenced by various environmental factors, including temperature.

5 Must Know Facts For Your Next Test

1. Algal blooms can be triggered by elevated temperatures, which accelerate algal growth rates.
2. Nutrient availability, particularly nitrogen and phosphorus, is a key factor driving algal blooms.
3. Harmful algal blooms (HABs) produce toxins that can negatively impact aquatic life and human health.
4. Temperature fluctuations can affect the species composition of algal blooms, favoring certain types over others.
5. Monitoring and managing water temperature is crucial for controlling the occurrence and impact of algal blooms.
