Erratum: Stable Isotope Analysis Reveals That Agricultural Habitat Provides an Important Dietary Component for Nonbreeding Dunlin
L’analyse des isotopes stables indique que les milieux agricoles fournissent une portion importante de l’alimentation du Bécasseau variable en période d’hivernage
In the original published version of this article, Figures 3, 5 and 6 erroneously displayed the Y axis in units of parts per thousand to the power of negative one (see original figures and captions below).
The correct figures and figure captions are now posted in the current published version of the article (see Figure 3, Figure 5 and Figure 6).
ORIGINAL PUBLISHED FIGURES AND CAPTIONS
Fig. 3. Cubic regression fit for date vs. predicted proportion of diet terrestrial for all Dunlin sampled over four winters. The predictive equation is: y = 0.1070 - 0.0012x + 0.0000084x² + 0.000000018x³, r² = 0.091, P = < 0.0001.
Fig. 5. Proportional use of fields as represented by transformed δ13C values and mean minimum temperature for previous 21-d period, separated by age class, adults represented by black filled circles, juveniles by open circles. The linear regression line of significantly increasing field use with declining temperature is shown in black for adults. The trend line shown for juveniles (dotted line) is for comparison only and is not significant.
Fig. 6. Proportional use of fields as represented by transformed δ13C values and mean total precipitation for previous 21-d period, separated by age class, adults represented by black filled circles, juveniles by open circles. ASY refers to after-second-year birds, and SY to second-year birds. The linear regression line of significantly increasing field use with increasing precipitation is shown in black for adults. The dotted line shown for juveniles is for comparison only and is not significant.
