“…There were between 4 and 15 seedlings of each seedlot per site, spread over 20 blocks, and the allocation of seedlots to blocks was random. The design is unbalanced because it is a subset of a larger trial (Miller et al, 2009) which contained treatments not of interest here (i.e., different fertilizers, tree guards and chemical repellent). It is possible that the additional treatments may have influenced animal feeding behavior, however, as treatments were randomly allocated among the 20 blocks, any ''neighbor'' effects should be negligible.…”

“…These are effective in the short-term because they actively deter feeding, but plants out-grow such methods relatively quickly. We have recently highlighted the effectiveness of genetic-based chemical resistance as a longer-term management option (Miller et al, 2009). …”

Abstract. The research literature on food selection by large herbivores is extensive. Still, we are generally lacking in our knowledge of the influence of potentially interacting chemical contents of the food. We made a qualitative review of a systematic literature search of studies that empirically link chemical contents of food to the food selection by northern cervids (genera Alces, Capreolus, Cervus, Dama, Odocoileus, Rangifer). We found that although the majority of the 98 relevant studies measuring any given food constituent (energy, protein, fiber, minerals, plant secondary metabolites) provided support for it acting as a driver of food selection (in either a negative or positive way), there was little support for the traditional hypotheses of maximization or limitation of any single constituent. Rather, because of the animals' need to acquire an appropriate intake of several constituents at the same time, our review highlights how new empirical studies need to focus on several food constituents in synchrony: (1) Study designs should capture sufficient variation in the content of food constituents in order to tease apart their many co-variations; and (2) insights about nutritional drivers may be lost if one uses only composite currencies such as crude energy, crude fiber, ash, or tannins, which may mask contrasting selection patterns of the lumped constituents. Season had an apparent influence on the selection of some food constituents, particularly various fiber fractions. In contrast, our review revealed a lack of evidence that cervids more strongly select for protein in summer than they do in winter. Our overall conclusion of the review is that interacting chemical contents of food make the nutritional value of a given food type into a varying entity. To better elucidate this variation, we need new technologies that non-invasively capture nutrient intake of free-ranging animals, across seasons.

Finding food is a key motivator of animal behavior and underpins an increasing number of conservation and wildlife management challenges. Introduced predators threaten many vulnerable native species, and some native predators are problematic for declining prey species. Likewise, browsing by native and introduced herbivores threatens endangered plant species, undermines habitat restoration efforts, and alters plant communities. Mammalian predators and herbivores use olfactory information to forage efficiently, pursuing cues that are useful and ignoring those that are not. Here, we present the theoretical basis for why olfactory misinformation should alter foraging decisions and provide compelling evidence that supports the theory. Drawing on this theory and evidence of the success of olfactory misinformation where it has been applied to date, we propose that there is enormous scope for its application more broadly in conservation and wildlife management. Such an approach offers a robust behavioral alternative for protecting valued plants and prey species that are otherwise vulnerable to foraging mammals.
