Geographic variation in body size and tegmen shape of the grasshopper Dichroplus elongatus (Orthoptera: Acrididae) from Central-West Argentina: morphological trait variation along environmental gradients.

Abstract excerpt

How phenotype varies across geographic space constitutes a key question in current evolutionary biology. Species with widespread geographic ranges are helpful models for examining phenotype variation patterns. Here we examined body size and tegmen shape variation in 12 populations of widespread agricultural pest Dichroplus elongatus collected in Central-West Argentina. D. elongatus showed significant phenotypic...
