Pre-migratory life history stages of juvenile Arctic birds: costs, constraints, and trade-offs.

abstract：:The fact that superabundant invasive pests are also sometimes highly aggressive represents an interesting paradox. Strong intraspecific aggression should result in high intraspecific competition and limit the densities reached by exotic species. One mechanism that can allow invaders to attain high densities despite hi...
