Effects of roads on Castanopsis carlesii seedlings and their leaf herbivory in a subtropical forest in China.

Dai XH, Xu JS, Cai LR - J. Insect Sci. (2014)

Bottom Line: However, both leaf miners and leaf gallers decreased in general from the road to the interior forest.There were interspecific differences in the effects of roads on leaf miner species and leaf galler species.The effects of the road on seedlings and insects could be explained by varying microhabitat conditions and different ecological strategies.

Scatterplots of number of seedlings (a), accumulated tree height (b), number of leaves (c), number of mines per leaf (d), and number of galls per leaf (e) against distance from road. The line was fitted by generalized additive models with a thirdorder polynomial smoothing spline. High quality figures are available online.

f02_01: Scatterplots of number of seedlings (a), accumulated tree height (b), number of leaves (c), number of mines per leaf (d), and number of galls per leaf (e) against distance from road. The line was fitted by generalized additive models with a thirdorder polynomial smoothing spline. High quality figures are available online.

Mentions: Numbers of C. carlesii seedlings in each 1-m2 area were highest 0.5 m and 6.5 m from the road but lowest 3.5 m from the road; however, if a subset of squares with large seedling numbers only were considered, seedling numbers seemed to drop with the increasing distances (Figure 2a). Accumulated tree heights and numbers of leaves and of C. carlesii seedlings in each square decreased linearly against the distances from the road. Considering larger values of tree heights and leaf numbers only, the trends were also similar (Figure 2b,c).
