Relationships between Mg concentration in soil, Oriental oak leaves and acorns, or larvae of the weevil <i>Curculio davidi</i> and latitude.

<p>Sampling was carried out across eastern China. Reduced Major Axis (RMA) regression slopes are 5.74 for soil, 1.63 for leaf, 0.91 for acorn and 1.11 for weevil larvae. Solid triangles, open circles, and solid circles are for data from 2007, 2008, and 2009, respectively. Different letters in the panel “All” indicate significant differences between slopes in a post-hoc comparison. The data of weevil Mg concentration (2.52 mg g^-1) from Anning and Lijiang (2.10 mg g^-1), Kunming, were not included in the statistics.
