Comparison of FCM concentrations (ng/g dry faeces; mean ± SE) according to breeding condition for males and females.

<p>Asterisks indicate significant differences (**p<0.01).</p

Log-transformed concentrations (mean ± SE) of faecal corticosterone metabolites (FCM, ng/g dry faeces) in breeding and non-breeding individuals in relation to the distance to the motorway.

<p>Significant differences are indicated by asterisks (*p<0.05).</p

Location of study area (shaded area) in the Comuna Torres del Paine (Region of Magallanes, Chile).

<p>Red dashed line indicates Torres del Paine National Park (TPNP) boundary. Black solid lines represent the surveyed road network.</p

Habitats used by guanaco and sheep in summer.

<p>Means and standard deviations of canonical scores for preferred and marginal areas of guanaco and sheep in the first two axes defined by GDA in non-protected areas in summer 2009 (A, B) and summer 2010 (C, D). Filled circle and solid line represent marginal areas. Open circles and dotted line represent preferred areas.</p

Main results of GDA per season to test the presence of differences in habitat variables among groups.

<p>Results of general discriminant analysis (GDA) per season to test whether groups of observations (i.e. availability in Torres del Paine National Park and in non-protected area, and sites selected by guanaco and sheep) could be distinguished on the basis of habitat variables. Values of 1-Wilks’ λ indicate the discriminatory power of models in the range of 1 (perfect discrimination) to 0 (no discrimination) for the whole model as well as for the sub-models obtained by removing the respective axis.</p

Results of the General Discriminant Analysis (GDA) in winter.

<p>Centroids of the observation groups are shown in the space defined by the first two discriminant axes of GDA. AP: Habitat availability in Torres del Paine National Park (TPNP); AN: Habitat availability in non-protected area; GP09: guanaco in TPNP in 2009; GP10: guanaco in TPNP in 2010; GN09: guanaco in non-protected area in 2009; GN10: guanaco in non-protected area in 2010; S09: sheep in non-protected area in 2009; S10: sheep in non-protected area in 2010. Different letters indicate significant differences between groups in first (superscript) and second axis (subscript) in MANOVA analysis according to the Unequal-N HSD <i>post-hoc</i> test (P<0.05).</p

Variables recorded for each guanaco (<i>Lama guanicoe</i>) and sheep (<i>Ovis aries</i>) sighting, and to estimate habitat availability at each control point.

<p>Each variable was measured for a 50 m radius from the animal or the centroid of the group.</p

Seasonal habitat availability in Torres del Paine National Park and in the non-protected area.

<p>Values are expressed as percentages, except topographic and physiognomic variables.</p><p>TPNP: Torres del Paine National Park.</p
