Trophic relationships of two species of grebe on a prairie lake based on stable isotope analysis

We used stable isotope analysis of carbon and nitrogen to investigate the trophic relationships of Western ( Aechmophorus occidentalis (Lawrence)) and Red-necked ( Podiceps grisegena (Boddaert)) Grebes from Lake Wabamun, a large prairie lake in north-central Alberta, Canada. We collected tissue samp...
