Fig. 4: Continent-wide causes for fecundity trends.
From: Continent-wide tree fecundity driven by indirect climate effects
Shaded contours are green (decreasing) to brown (increasing). Responses to climate variables (∂f/∂C) in a are multiplied by climate change (×dC/dt) in Fig. 2a to give the direct effect (∂f/∂C × dC/dt) in panel (b) (first term of Eq. (1)). The direct effect in b is added to the indirect effect that comes through tree growth (terms 2 and 3 of Eq. (1)) to give the full effect in panel (c). Units are proportionate change in fecundity per °C or per mm[-month] moisture deficit in panel (a) and per year in panels (b, c). White areas lack inventory plots. The brown contour indicates zero.
