Relationships between must sugar content (°Oe) and mean April to August temperature (°C).

<p>1864–1905 <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0069015#pone.0069015-Eifler1" target="_blank">[24]</a> (black solid circles) and 1962–2010 (annual vintage records) (dark grey solid rhombs). Regression lines superimposed.</p

Time series of mean must sugar content (°Oe) (left y-axis), originating from Eifler [24] (black solid circles) and recent annual vintage records (dark grey solid rhombs).

<p>Vertical bars connect minimum and maximum must sugar content for each year. Mean April to August temperature are plotted against the right y-axis (dotted line in light grey). Regression lines superimposed.</p

Time series of mean yield (hl/ha), originating from Eifler[24], [54] and Weigand [25] (black solid circles), from Bayerisches Staatsministerum für Ernährung [26] (light grey solid triangles) and annual vintage records (dark grey solid rhombs).

First arrival dates for rural (solid symbols and lines) and urban observations (open symbols and dotted lines) averaged over seven short distance migrants (lower part of graph) and 11 long distance migrants (upper part of graph) in Western Poland 1983–2010.

<p>Regression lines superimposed. Note than the same set of species was included in all years and in both habitats.</p

The relationship between standard deviation (SD) of first arrival dates and mean first arrival date (shown as day of the year, 1 = Jan 1 etc.) for 18 species recorded at rural sites (solid symbols) and urban sites (open symbols) in Western Poland.
