Implications of species addition and decline for nutrient dynamics in fresh waters

摘要: Abstract: In terrestrial and aquatic ecosystems, organisms directly affect nutrient storage cycling by sequestering nutrients via growth remineralizing excretion egestion. Therefore, species introductions extirpations can profoundly remineralization rates, present a challenge for conserving ecosystem function in fresh waters. The literature of consumer-driven dynamics is growing rapidly, but studies consumer effects on across among ecosystems are limited. We compared the 3 grazing taxa, nonnative armored catfish Mexican streams, native mussels Oklahoma tadpoles Panamanian remineralization. examined interactions organismal stoichiometry biomass, storage, size these groups following decline (tadpoles mussels) or introduction (armored ...
