Influence of Gap Size and Position within Gaps on Light Levels

Figure 2

Mean percentage of total light relative to open conditions at different positions along the north-south axis of (a) small gaps (D/H ratio ≤ 0.5, (b) medium gaps (D/H ratio ), and (c) large gaps (D/H ratio ≥ 1.5). For hemispherical photographs (circles), positions with an asterisk (*) have significantly higher light levels than under closed forest canopy (Dunnett’s test). Values in brackets represent standard error.
