Isotopic niche variation in a higher trophic level ectotherm: highlighting the role of succulent plants in desert food webs.
Stable isotope analysis of animal tissues allows description of isotopic niches, whose axes in an n-dimensional space are the isotopic koip share price ratios, compared to a standard, of different isotope systems (e.g.δ(13)C, δ(15)N).Isotopic niches are informative about where an animal, population or species lives and about what it consumes.Here
