Population dynamics of wild reindeer (Rangifer tarandus L.) on the Taimyr Peninsula: A simulation model

“…Problems of population dynamics of domestic and wild reindeer in the circumpolar region attract grow ing attention. For instance, domestic reindeer on the Yamal Peninsula are one of the main factors influenc ing the state of natural systems and vegetation resources (Kryazhimskiy et al, 2010). The situation with wild reindeer is different because their abundance is not stimulated artificially, although some attempts at regulating it have been made (Malygina, 2005).…”
