Ecology, life history and resource allocation in the ant, Leptothorax nylanderi.

abstract：:Metamorphosis can disrupt the correlation structure between juvenile and adult traits, thus allowing relatively independent evolution in contrasting environments. We used a multiple experimental approach to investigate how diet quality and larval predation risk affected the rates of growth and development in painted f...
