Feces from Piscivorous and Herbivorous Birds Stimulate Differentially Phytoplankton Growth [PDF]
Water (Switzerland), 2019 Aquatic birds may impact shallow ecosystems via organic and nutrient enrichment with feces. Such input may alleviate nutrient limitation, unbalance their ecological stoichiometry, and stimulate primary production. Herbivorous and piscivorous birds may produce different effects on aquatic ecosystems due to different physiology, diet and feces elemental ...
