A reexamination of age-related variation in body weight and morphometry of Maryland Nutria
Article Abstract:
Age-related variation in morphometry was documented for many species and the knowledge of growth patterns could be helpful for modeling energetics, detecting physiological influences on populations, and predicting age. Data from necropsies of 1,544 nutria(Myocastor coypus) collected in Maryland, USA is used to evaluate the accuracy of previously published models for prediction of nutria age from body weight. The evaluation data corresponds with 95% prediction intervals from the new models.

Nutritional consequences of gastrolith ingestion in blue-winged teal: a test of the hard-seed-for-grit hypothesis
Article Abstract:
Research describing the effects of substituting hard seed for grit in the diet of blue winged teal is presented. True metabolizable energy measurements did not support the presumed nutritional benefit of gastrolith ingestion.

Determinants of lead shot, rice, and grit ingestion in ducks and coots
Article Abstract:
Research is presented concerning the relationship existing between bill morphology, lead shot ingestion, diet and the selection of grit size in common coots and eight duck species over-wintering in the Ebro Delta, Spain.
