Food Web Interaction With Expanations Arctic Tundra Although trophic interaction cycles are also found south of the tundra biome (e.g., kendall et al. 1998), such cycles appear to be most pronounced in the arctic because of the very short plant growth season, low primary productivity, and simple food web structure (oksanen and oksanen 2000). A, arctic tundra study sites (red dots on the map).pictograms represent the most abundant herbivores for each site. background map of bioclimatic zone is derived from maximum normalized difference.
Arctic Food Web Arctic Tundra The churchill fox project is a long term research project focused on studying food web interactions on the arctic tundra and how climate change affects these interactions, with a secondary focus on gaining a comprehensive understanding of the functional role that arctic foxes play on the tundra. In addition, future research on nutrient cycling in arctic lake ecosystems will benefit from the inclusion of other food web components, given that the interactions described in this study do not. A generalized food web for the arctic tundra begins with the various plant species (producers). herbivores (primary consumers) such as pikas, musk oxen, caribou, lemmings, and arctic hares make up the next rung. omnivores and carnivores (secondary consumers) such as arctic foxes, brown bears, arctic wolves, and snowy owls top the web. 2. methods. predator–prey interactions play an important role in the tundra food web of bylot island, nunavut, canada (73° n, 80° w) and have been parametrized using data from long term studies of population abundance and diet at this site [].
