Stable isotope analysis (SIA) has proven to be a useful tool in reconstructing diets,
characterizing trophic relationships, elucidating patterns of resource allocation, and …

Stable isotopes of carbon and nitrogen are mainstay tracers in diverse fields of ecology,
particularly in studies of food webs. Investigators are generally interested in tracing dietary C …

Scientists concerned with organic matter flow and food web structures in aquatic systems
have increasingly realized the potential for using stable isotopes as both natural tracers and …

Stable isotopes have been extensively used to trace element cycles and their incorporation
into food webs. This chapter provides a brief introduction to the principles of using stable …

Linking foraging and breeding habitats is key to the understanding of behaviour, ecology
and demography of migratory species. Establishing such connections has long been …

The availability of nitrogen plays a central role in regulating biological productivity in many
marine environments. The distribution of the stable isotopes of nitrogen within marine …

The Brazilian oil spill, from August 2019 to January 2020, was considered the most
extensive accident in tropical oceans. We estimated the concentration of oil droplets that …

Quantifying the diet of sympatric co-occurring predatory species is a challenging task, made
more so when investigations attempt to focus on specific age groups. This is the task that …

Stable isotopic composition of carbon (δ 13 C POM) and nitrogen (δ 15 N POM) in the
particulate organic matter (POM) is used to identify sources of organic carbon and nutrients …

Carbon and nitrogen stable isotope ratios were measured in 157 fish bone collagen
samples from 15 different archaeological sites in Belgium which ranged in ages from the 3rd …
