FIGURE 1. Locations of the 179 modern ecoregions (colored areas) and the five fossil localities (stars) used in this study. Ecoregions are overlain on a grayscale global mean annual precipitation (MAP) map derived from Fick and Hijmans (2017), with lighter regions indicating areas of higher MAP and darker regions indicating areas of lower MAP. Abbreviations: LV, La Venta, Colombia; QH, Quebrada Honda, Bolivia; RU, Rümikon, Switzerland; SC, Santa Cruz, Argentina; TG, Tinguiririca, Chile.

Fig. 4 in A community analysis approach to parasite transmission in multi-host systems: Assemblages of small mammal prey and Echinococcus multilocularis in an urban area in North America
Fig. 4. Map showing the geographic distribution of three small mammal assemblage types predicted for the City of Calgary area by a multinomial logistic regression (MLR) model associating the environmental variables to assemblage types, developed from data collected in 2012 and 2013 (Liccioli et al., 2014). Note how large portion of BWM and NHP were classified as assemblage 1 as expected, but also large portion of FCPP, where it was not expected.

Fig. 2. Dendrograms derived from the Bray-Curtis similarity of small mammal assemblages in five parks and natural areas in urban Calgary, AB, Canada, 2012–2013. a) Dendrogram using abundance data and group-average clustering algorithm. The dashed line indicates the cluster cut-off line of 45% similarity. Symbols for each site indicate the prevalence of definitive hosts (EmDH) and presence (1) or absence (0) of infected small mammals (EmIH). b) Dendrogram using abundance data and complete-linkage clustering algorithm.
