ABSTRACT 1 Stable isotope analysis (SIA) has the potential to become a widespread tool in
mammalian ecology, because of its power in resolving the ecological and behavioural …

The authenticity of meat is now an important consideration in the multi-step food chain from
production of animals on farm to consumer consumption of the final meat product. A range of …

Movement patterns and annual migrations of animals are vital components of their ecology
but have generally been poorly studied due to fundamental limitations in using exogenous …

Stable isotopes have proven to be a useful tool for deciphering food webs, examining
migration patterns and determining nutrient resource allocation. In order to increase the …

Diet–tissue discrimination factors (Δ15N or Δ13C) and turnover times are thought to be
influenced by a wide range of variables including metabolic rate, age, dietary quality, tissue …

Spatial and temporal variation can confound interpretations of relationships within and
between species in terms of diet composition, niche size, and trophic position (TP). The …

Stable isotopes are an important tool for physiological and behavioral ecologists, although
their usefulness depends on a thorough understanding of the dynamics of isotope …

Tissue stable isotopes can be used for dietary reconstruction provided that the factors
influencing turnover rates and trophic discrimination factors (TDFs) between consumer …

The climate change-induced northward movement of sub-Arctic marine mammals increases
their range overlap and interactions with native Arctic species. We compared feeding …

In recent years, it has become evident that limitations exist in our ability to meaningfully
assess palaeodiet using stable isotope compositions. These limitations in part arise …
