在澳大利亚亚热带的万年青雨林中，比较了藤本植物和树木的凋落叶量。几个演替阶段在主要网站的代表。藤本植物占该样地总断面积的2.2%（69.6 m2 ha-1），但占叶凋落物的24%（5.9-6.5 ha-1 y-2）。落叶量的年与年之间的微小变化归因于严重风暴和干旱的发生。藤本植物是负责约17%的叶凋落物在春季，21%，在夏季高峰期，在秋季和40%，更多的藤本植物比树木落叶。叶凋落物生产的23个物种的藤本植物，在其断面积内的主要网站，是，平均15倍的34个树种，但下降更陡峭的物种组之间的早期和后期的演替。卷须藤本植物，不像twiners和scramblers，仅限于“早期”演替组，和他们的树叶遍布冠层表面，最大限度地提高光的拦截。它的结论是，这有助于更大的生产落叶，每单位断面积，卷须比其他攀援植物，并从藤本植物叶凋落物的演替下降。
ABSTRACT Leaf litter production by lianes (=lianas) and trees was compared in an evergreen rain forest in subtropical Australia. Several successional stages were represented at the main site. Lianes contributed 2.2% of total basal area (69.6 m2 ha-1) of this site, but 24% of leaf litterfall (5.9–6.5 tha-1 y-2 over two years. Minor year-to-year variation in litterfall was attributed to incidence of severe storms, and drought. Lianes were responsible for about 17% of leaf litterfall in spring, 21% in the summerpeak, and 40% in autumn, more lianes than trees being deciduous. Leaf litter production by 23 individual species of liane, in relation to their basal area within the main site, was, on average, 15 times as great as that by 34 tree species, but declined more steeply between the species-groups of early and later succession. Tendrillar lianes, unlike twiners and scramblers, were confined to the ‘early’ successional group, and their foliage was spread across canopy surfaces, maximizing light interception. It was concluded that this contributed to greater production of leaf litter, per unit basal area, by tendrillar than by other climbers, and to the successional decline in leaf litterfall from lianes.
