Biology and Ecology:

Infections of caribou  are reported with the lungworm, Varestrongylus eleguneniensis.(Loginova et al., 2023).

Rangifer is considered a secondary definitive host for V. eleguneniensis, with muskoxen (Ovibos moschatus) a primary host (Verocai et al. 2014).  Loginova et al (2023) consider that there is a possibility that V. eleguneniensis (and O. macrotis) were translocated and introduced to the Taimyr area of Russia with muskoxen from Alaska and Canada. Apparently 30 muskoxen were introduced to Taimyr in the 1970s: ten of them from Banks Island (western Canada) and twenty came from Nunivak Island (western USA). By 2011 they had increased to 7200 animals (Argunov 2018).
