...Gail H. Fitzhugh; James H. Marden ABSTRACT Maximum lift production and the thermal sensitivity of lift production increase dramatically during adult maturation of Libellula pulchella dragonflies. Here, we report that the mechanistic basis for this transition appears to involve a developmental...

...James H. Marden; Melissa G. Kramer; John Frisch ABSTRACT Thoracic temperatures ( T th ) of Libellula pulchella dragonflies during activity in the field were compared between age classes and with laboratory measures of optimal thoracic temperature for flight performance ( T th,opt ; a trait...

...James H. Marden ABSTRACT Newly emerged adult dragonflies are physiologically immature in a number of ways, including the mass, ultrastructure and biochemistry of their flight muscles. In Libellula pulchella dragonflies, adult maturation of flight muscle is accompanied by striking changes in thermal...
