The development of the isotopic niche, an n-dimensional hypervolume (with n being the
number of isotopes) occupied by a population in delta space, has revolutionized the study of …

A common use of stable isotope analysis in mammalogy is to make inferences about diet
from isotope values (typically δ13C and δ15N) measured in tissues and food sources of a …

Stable isotope ratios (typically of carbon and nitrogen) provide one representation of an
organism's trophic niche and are widely used to examine aspects of food web structure. Yet …

Mangrove ecosystems are highly productive tropical coastal ecosystems which have a
potentially high impact on the carbon budget of the tropical and global coastal zone. The …

Stable‐isotope analysis (SIA) can act as a powerful ecological tracer with which to examine
diet, trophic position and movement, as well as more complex questions pertaining to …

The recent expansion of natural abundance stable isotope methods has rapidly increased
our understanding of freshwater food web ecology. Investigators now routinely use stable …

Stable isotopes have been used extensively to study food-web functioning, that is, the flow of
energy and matter among organisms. Traditional food-web studies are based on the natural …

Human activities have serious impacts on marine apex predators. Inadequate knowledge of
the spatial and trophic ecology of these marine animals ultimately compromises the viability …

Understanding matter circulation in the biosphere constitutes one of the fundamental
research objectives for ecologists. Stocks of materials, their distribution, and their fluxes …

Over the last few decades, measurements of light stable isotope ratios have been
increasingly used to answer questions across physiology, biology, ecology, and …
