Abrupt transitions leading to algal blooms are quite well known in aquatic ecosystems and have important implications for the environment. These ecosystem shifts been largely attributed nutrient dynamics food web interactions. Contamination with heavy metals such as copper can modulate ecological interactions which turn may impact functioning. Motivated by this, we explored effect of enrichment...
