Fig. 3: Sites and species trends.
From: Continent-wide tree fecundity driven by indirect climate effects
a Longitudinal studies in black (opacity proportional to numbers of sites) and opportunistic in white. Shaded ecoregions are desert/shrub/grass (browns), montane (blues), and mixed forest (greens). b Trends in mean log (proportionate) fecundity by species from sites in a range from negative (declining) to positive. As would be the case for any meta-analysis, the time scales for which trends are evaluated vary (see “Methods” section). Species belong to color-coded families below that are listed in Supplementary Data 2. There is no relationship with phylogeny (i.e., no trend in box color from left to right). Summaries in b include mean (crosshairs), 95% of site means (bold line), and range of site means (whiskers). The number of sites (n) contributing to b is shown below.
