A 20-Year Record of Alpine Grasshopper Abundance, with Interpretations for Climate Change

A 20-year capture-recapture study of alpine grasshoppers spanned three distinct sequences of abundance, featuring in turn dis-equilibrium, equilibrium and secondary cyclic equilibrium. This succession of population patterns in the most abundant species, Paprides nitidus, retained high stability between generations. It arose via superimposed life- cycle pathways and adaptive responses between grasshopper phenologies and their environmental constraints.
