1. Toward understanding the geography of omnivory, we tested three hypotheses that predict the proportion of animal tissue consumed: The Sodium Limitation Hypothesis predicts that omnivores increase a
Temperature appears to be the best predictor of species composition of planktonic foraminifera communities, making it possible to use their fossil assemblages to reconstruct sea surface temperature (S
Diet compositions were estimated using SIAR [21] and are presented as mean estimates with 95% credibility intervals (in parentheses). The initial model (SIAR Model 3) estimates the relative contributi
The plant species were collected at Sassendalen, Svalbard in June 2005. n gives sample size as well as number of species for each diet component. For the calculation of isotope...
