Morphometry and feeding behaviour in two sympatric orthopterans in the Kalahari (Namibia): The trait as you like it

摘要: High entomological trait variability is supposed to reflect a combination of intra and inter-phenotype signals. These functional signals are mirroring different behaviours feeding habits. Our main aim was assess if the distribution body measurements two sympatric species further more significantly influenced by gender (intraspecific variance) or (interspecific variance). To achieve this, we collected in Namibia (Africa) tettigoniids belonging Acanthoplus discoidalis longipes. We measured field total length, maximal pronotal width third pair legs (femur tibia) 106 adults. derived mass volume from empirical length values sampled specimens compared them with literature data on African tettigoniids. The discriminant analysis shows that at level locomotory traits as captured tibia femur lengths size account for 99% variance clearly separate species. However, intraspecific distributions between males females small contrast interspecific distributions. explain this latter phenomenon consequence dietary differences due nitrogen contents host plants A.
