Fig. 1 in The biogeography of the caribou lungworm, Varestrongylus eleguneniensis (Nematoda: Protostrongylidae) across northern North America
Fig. 1. Map of Northern North America, including Alaska, USA, Canada and Greenland depicting the geographic distribution of caribou subspecies (Rangifer tarandus sspp.). The distribution of the caribou lungworm, Varestrongylus eleguneniensis, and the muscleworm, Parelaphostrongylus andersoni in caribou is shown based on compiled data from the present study, and all reports in the literature (Lankester and Hauta, 1989; Lankester and Fong, 1998; Kutz et al., 2007, 2012; 2013; Verocai et al., 2013; Kafle et al., 2017a, 2017b; Turgeon et al., 2018). The historic southern range of distribution of caribou is shown as a dotted line to assist in the discussions on the historical biogeography of V. eleguneniensis and Rangifer. (See Fig. S1 and Fig. S2 for the distribution maps for V. eleguneniensis and P. andersoni separately).
