Quantity and quality: unifying food web and ecosystem perspectives on the role of resource subsidies in freshwaters.

abstract：:Adaptive developmental plasticity has been demonstrated across a number of taxa in response to variables such as photoperiod, resource abundance, and predator presence. Demographics also vary temporally and spatially within populations, but few studies have examined the possibility that developmental plasticity in res...
