The composition, diversity, structure and host preference of climbers in a tropical lowland rain forest at Ile-Ife were examined in this study. Six plots (0.25 ha) were established in the secondary forest. In each plot, all the tree species ≥ 2 m in height were identified to species level and enumerated. The trees were examined for the presence of climbers and the number of climbers counted. The girth at breast height (gbh) of both trees and lianas were measured. The data collected were used to establish the floristic composition, density, diversity, evenness, basal area and climber infestation on tree species in the forest. Relationship and association of climber infestation on host species and the climber structural parameters were examined. Host bark texture was determined visually. There were 61 climber species distributed into 53 genera and 28 families. Host species bark structure had no significant relationship with climber infestation in the forest. There was a positive relationship between the abundance of host species and climbers. Although bark structure and climber infestation showed no significant association with infestation, girth sizes of host species and abundance of tree species had more influence on climber infestation in the forest.

尼日利亚次要低地雨林中的登山者出没及其与寄主树种的丰度和结构的关系

在这项研究中,研究了在Ile-Ife的热带低地雨林中登山者的组成,多样性,结构和寄主的偏好。在次生林中建立了六个土地(0.25公顷)。在每个样地中,将所有高度≥2 m的树木物种识别到物种水平并进行列举。检查了树木是否存在登山者,并计算了登山者的数量。测量了树木和藤本植物的胸高周长(gbh)。收集到的数据用于确定森林树木种类的植物组成,密度,多样性,均匀度,基础面积和爬虫侵扰。研究了爬虫侵染对寄主物种和爬虫结构参数的关系和关联。目测确定宿主树皮的质地。共有61个登山者物种,分布在53个属和28个科中。寄主物种的树皮结构与森林中的登山者侵扰没有显着关系。寄主物种的数量与登山者之间存在正相关关系。尽管树皮结构和爬虫侵染与侵染没有显着相关性,但寄主种类的周长大小和树木种类丰富对森林中的爬虫侵害影响更大。
