摘要: Abstract Previous studies have demonstrated the potential of carbon and nitrogen stable isotope analysis (SIA) feces for use in understanding dietary components sources. These suggest that SIA is useful because it noninvasive provides more recent information integrated over a shorter time period than tissues. We sought to determine whether could be employed American black bears (Ursus americanus) Utah. Using archived feces, we compared with gross fecal analyses (GFA) if relationship existed. The percent volume grass pine nuts were only significant indicators δ13C feces. amount animal matter was sole indicator δ15N value Although these measures weakly indicative (R2 ≤ 0.21), interesting even an environment isotopically homogenous, provided on contribution components. comparatively ...
