...-history, physiological and behavioral traits. We used the variable field cricket, Gryllus lineaticeps , which exhibits a wing dimorphism that mediates two distinct life-history strategies during early adulthood. Long-winged individuals invest in flight musculature and are typically flight capable, whereas...

...Alexander R. Gerson; Joely G. DeSimone; Elizabeth C. Black; Morag F. Dick; Derrick J. Groom ABSTRACT Migratory birds catabolize large quantities of protein during long flights, resulting in dramatic reductions in organ and muscle mass. One of the many hypotheses to explain this phenomenon is that...
