A cross-system synthesis of consumer and nutrient resource control on producer biomass.

abstract：:While collective decision-making is recognised as a significant contributor to fitness in social species, the opposite outcome is also logically possible. We show that collective movement decisions guided by individual bison sharing faulty information about habitat quality promoted the use of ecological traps. The fre...
