| a field validation of plasma metabolite profiling to assess refueling performance of migratory birds. | plasma metabolite profiling offers a potential means to assess stopover refueling performance of migratory birds from a single capture. however, this method has not previously been validated where site quality has been determined independently using analysis of capture data. we captured and blood sampled six passerine bird species refueling at known high-quality (base) and low-quality (tip) sites at long point, ontario, canada. plasma triglyceride, an indicator of fat deposition, was higher at t ... | 2005 | 15702470 |
