Stoichiometric And Stable Isotope Ratios Of Wild Lizards In An Urban Landscape Vary With Reproduction, Physiology, Space And Time, Andrew M. Durso, Geoffrey David Smith, Spencer B. Hudson, Susannah S. French

Ecology Center Publications

Spatial and temporal variation in stoichiometric and stable isotope ratios of animals contains ecological information that we are just beginning to understand. In both field and lab studies, stoichiometric or isotopic ratios are related to physiological mechanisms underlying nutrition or stress. Conservation and ecosystem ecology may be informed by isotopic data that can be rapidly and non-lethally collected from wild animals, especially where human activity leaves an isotopic signature (e.g. via introduction of chemical fertilizers, ornamental or other non-native plants or organic detritus). We examined spatial and temporal variation in stoichiometric and stable isotope ratios of the toes of Uta …
