The wide multidimensional nutritional niche of brown bear supports previous suggestions that, as a species, brown bears may be better equipped to face some of the nutritional challenges associated with climate change, such as changes in available food resources (Roberts, Nielsen, & Stenhouse, 2014). Yet, there may be unexpected relationships between brown bears and changing climate, as their macronutrient preferences may have broad ecological implications when the timing of seasonal food resources changes. One study, for example, found that brown bears preferentially switched to eating fruit that became available several weeks early in place of available spawning salmon they historically consumed during that period (Deacy et al., 2017). Brown bear's preference for high proportions of nonprotein macronutrients was given as a possible explanation for this diet shift (i.e., the proportion of macronutrients in some fruit is very close to the preferred ratio of captive bears; Coogan et al., 2014). This situation is similar to the case of bears receiving anthropogenic subsidies, in that they are able to feed on foods offering macronutritional properties otherwise temporally or ecologically unavailable.
