Identifying feeding patterns of large-bodied predators is necessary for predicting their potential effects on food web dynamics. However, diet information from stomach contents can be impractical to obtain because required sample sizes can be prohibitively large. In contrast, diet estimates obtained using Bayesian stable isotope mixing models require less sampling effort and can also reveal both population- and individual-level variation in diet. Here, we used an extensive stable isotope data…

Are stable isotope ratios suitable for describing niche partitioning and individual specialization?

The circumstances and approaches that are necessary to evaluate niche partitioning and individual specialization are discussed, and key considerations for the associated application of stable isotope ratios are outlined.

A Multi-Tissue, Multi-Species Assessment of Lipid and Urea Stable Isotope Biases in Mesopredator Elasmobranchs

The application of stable isotope analysis (SIA) is increasing in elasmobranch trophic ecology, but inconsistency remains in terms of the tissue pre-treatment methods chosen to remove biases

Energetic consequences of resource use diversity in a marine carnivore.

Understanding how intraspecific variation in the use of prey resources impacts energy metabolism has strong implications for predicting long-term fitness and is critical for predicting



Prey dominance shapes trophic structure of the northern California Current pelagic food web: evidence from stable isotopes and diet analysis

The prevalence of omnivory observed here is probably due to high primary production that supports an abundance of large zooplankton prey, such as euphausiids, which may be a more available prey resource for a broad range of predators.

Ontogenetic and Among-Individual Variation in Foraging Strategies of Northeast Pacific White Sharks Based on Stable Isotope Analysis

The diet of an apex predator, the white shark, is evaluated by measuring the stable carbon and nitrogen isotope composition of vertebral growth bands to create lifetime records for 15 individuals from California, revealing substantial ontogenetic and individual dietary variation within a white shark population.

Using Stable Isotope Analysis to Understand the Migration and Trophic Ecology of Northeastern Pacific White Sharks (Carcharodon carcharias)

Stable isotope analysis can provide insight into the trophic ecology and migratory behavior of marine predators, especially when coupled with electronic tagging data, and mixed model results indicated that sharks foraged at a higher relative rate in coastal habitats.

Variable δ15N Diet-Tissue Discrimination Factors among Sharks: Implications for Trophic Position, Diet and Food Web Models

An assessment of a range of reported ∆15N values that can hypothetically serve as surrogates for describing the predator-prey relationships of four shark species that feed on prey from different trophic levels found the most suitable species-specific ∆ 15N values decreased with increasing dietary-δ15Nvalues based on stable isotope Bayesian ellipse overlap estimates of shark and the principal prey functional groups contributing to the diet determined from stomach content analyses.

Diet- and tissue-specific incorporation of isotopes in the shark Scyliorhinus stellaris, a North Sea mesopredator

A method for isotope mixing models using diet-specific DTDFs is proposed, which improves diet reconstruction estimates for animals, particularly mesopredator sharks that consume a large range of prey types.

Stable isotope mixing models elucidate sex and size effects on the diet of a generalist marine predator

Stable isotope analyses identified significant harbor seal sexand size-based differences in diet and foraging habitat use and these differences present complex challenges for fisheries management and for the design of marine reserves.

Contrasting patterns of individual specialization and trophic coupling in two marine apex predators.

Individual specialization may be an important feature of trophic dynamics of highly mobile marine top predators and should be explicitly considered in studies of marine food webs and the ecological role of top predators.
