The carbon isotope values in the exhaled breath of an animal mirror the carbon isotope
values of the metabolic fuels being oxidized. The measurement of stable carbon isotopes in …

Stable isotope analysis has provided insight into the dietary and habitat patterns of many
birds, mammals and teleost fish. A crucial biological parameter to interpret field stable …

The interpretation of isotopic data gathered in the field often demands knowing the rate at
which isotopes are incorporated into different tissues and species, and the discrimination …

Urbanisation is one of the most significant threats to biodiversity, due to the rapid and large‐
scale environmental alterations it imposes on the natural landscape. It is, therefore …

Stable isotope analysis has become a standard ecological tool for elucidating feeding
relationships of organisms and determining food web structure and connectivity. There …

Reptiles are key components of modern ecosystems, yet for many species detailed
characterisations of their diets are lacking. Data currently used in dietary reconstructions are …

13C breath testing is increasingly used in physiology and ecology research because of what
it reveals about the different fuels that animals oxidize to meet their energetic demands …

Allocation of acquired resources to phenotypic traits is affected by resource availability and
current selective context. While differential investment in traits is well documented, the …

Stable isotope analysis has provided insights into the trophic ecology of a wide diversity of
animals. Knowledge about isotopic incorporation rates and isotopic discrimination between …

Trophic morphology affects resource acquisition; therefore, species differences in such traits
may be informative for inferring resource use overlap and potential species interactions. In …
