Excess levels of nitrogen, phosphorus causing deformed frogs

Copyright Pieter JohnsonEutrophication is caused by higher phosphorous and nitrogen that create a profound impact on the food web, threatening the frogs’ existence.A collaboration involving ecologists at WUSTL and the University of Wisconsin strongly points to farming practices and development, two factors that create a condition called eutrophication in ponds and wetlands, as factors behind the high incidence of deformed frogs. Eutrophication is caused by higher phosphorus and nitrogen (prime components of agricultural fertilizer) levels in wet ecosystems. Higher levels of these nutrients cause a profound impact on the food web that imperils the frogs’ existence.
