Caw Ridge Annual Data

Description of data: Both sheets contain longitudinal data set collected on female mountain goats at Caw Ridge, Alberta, Canada between 1988-2015. The first sheet includes annual data related to reproduction, survival, population density, and a quality index based on female social rank and body mass. This data was used to produce Table 2, Figure 4, and Table S3. The second sheet includes lifetime data related to reproduction, longevity, population density, and a quality index. This data was used to produce Table 1, Figure 1, Figure 2, Figure 3, Table A1, Table S1, Table S2, and Figure S1

Conceptual representation of predictions from alternative hypotheses on compensation and resource availability integrating browsing pressure.

<p>The Compensatory Continuum Hypothesis (CCH, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0051940#pone.0051940-Maschinski1" target="_blank">[17]</a>) predicts higher compensation for tissues lost to herbivores in high resource environment up to a threshold browsing pressure and lower compensation in low ressource environment (A). The Growth-Rate Hypothesis (GRH, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0051940#pone.0051940-Hilbert1" target="_blank">[18]</a>) predicts higher compensation in low resource environment under low to moderate browsing pressure as plants have not yet attain their full growth potential (B). The prediction of equal tolerance between high and low resource environments of the Limiting Resource model (LRM, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0051940#pone.0051940-Wise1" target="_blank">[23]</a>) (C). In this situation, a resource is limiting plant growth while herbivory affects the use or acquisition of another non-limiting resource. As herbivory does not create a limitation in this alternate resource, compensation potential should be equal in high and low limiting resource environments. Intercepts are different between high and low resources, as we do not expect a similar plant biomass in those environments.</p

Representation of 1 block of an experiment testing the effects of fertilisation and browsing on compensation by <i>Betula glandulosa.</i>

<p>The experimental design was installed in 2009 at Deception Bay (Québec, Canada). Dark grey plots are fertilized with 10 g N/m². The levels of the browsing treatment (0, 25 and 75% of available shoots >5 and ≤12 cm stripped of their leaves) were distributed randomly between subplots (pale grey). Numbers adjacent to dotted lines indicate their length. Each treatment was applied once a year.</p

Proportion of ice and water

Proportion of ice and water on the largest water bodies used by migratory caribou of the Rivière-aux-Feuilles herd in northern Quebec. Ice and water coverages were estimated using 8-day averaged MODIS values from 2000 to 2014. "Sum lake" and "Sum lake-ice" respectively represent the sum of pixels with values of 37 (ie. freshwater) or 100 (ie. lake ice) on MODIS maps

Productivity and structural responses of <i>Betula glandulosa</i> in response to simulated browsing (0, 25% and 75% of shoots ≥5 cm stripped of their leaves) and fertilisation (natural level and addition of 10 g N m⁻²) during two years (2009–2010).

<p>ANOVA results are based on linear mixed models with block (n = 5) and all interactions involving block as random factors and year as a repeated measure, except for leaf area, for which the analysis was only performed in 2010. Numbers in bold are statistically significant (α = 0.05).</p>*<p>Leaf biomass is estimated from point intercept on leaves.</p
