The effects of formalin fixation and fluid storage on stable isotopes in rodent hair

Stable isotopes are increasingly being used to unlock the wealth of information contained in specimens preserved in museum collections. However, preservation methods that employ formalin may confound ecological interpretations. To quantify the …

Using stable isotopes to quantify species interaction strengths

Understanding ecological interaction strengths is one of the main objectives of ecology. Recently, two methods for estimating interaction strengths of predator- prey interactions in nature have been proposed: a field observation approach proposed by …

Merging Resource Availability with Isotope Mixing Models: The Role of Neutral Interaction Assumptions

Bayesian mixing models have allowed for the inclusion of uncertainty and prior information in the analysis of trophic interactions using stable isotopes. Formulating prior distributions is relatively straightforward when incorporating dietary data. …
