Genetically-based trade-offs in response to stoichiometric food quality influence competition in a keystone aquatic herbivore.

abstract：:With rapidly increasing rates of contemporary extinction, predicting extinction vulnerability and identifying how multiple stressors drive non-random species loss have become key challenges in ecology. These assessments are crucial for avoiding the loss of key functional groups that sustain ecosystem processes and ser...
