"New research indicates that the middle [of the food chain] -small insectivorous birds and lizards-are critically important to overall health of an ecosystem, and actually help promote greater biomass." "Gruner and a team of other researchers looked at more than 100 studies insect predation by birds, bats or lizards and found that, regardless of the predator in question, their presence was associated with a 40 percent reduction in damage to plants. In turn, a healthy population of insectivores was linked to a 14 percent increase in plant biomass."
