“…Bobcats will sometimes create more controlled repeated scrapes with both hind feet and deposit urine or scat at one end (Elbroch et al 2012). Scrapes are not commonly associated with gray foxes, though they, like coyotes and bobcats, will often deposit scats in groups (Fritzell and Haroldson 1982). C:N ratios vary across ecosystems and through food webs, reflecting underlying organismal allocations to major molecules and chemical structures; terrestrial vascular plants tend to have high C:N ratios (Meyers 1994, Prahl et al 1994 while animals tend to be much more nutrient rich and therefore have much lower C:N ratios (Sterner and Elser 2002).…”
