The Impact Of Forest Successional Status On Community Structure Of Neotropical Cerambycid Beetles, Lin Li Jan 2015

The Impact Of Forest Successional Status On Community Structure Of Neotropical Cerambycid Beetles, Lin Li

Dissertations and Theses

Due to anthropogenic activities, tropical rain forests face many challenges in sustaining biodiversity and maintaining global climates. This project examines how forest successional status affects community composition of saproxylic cerambycids, which, as early colonists of moribund trees, have an important role in nutrient cycling. In the lowland rain forest of Costa Rica, thirty-nine trees in five plant families (Fabaceae, Lecythidaceae, Malvaceae, Moraceae, and Sapotaceae) were sampled in a mosaic of old growth and secondary forest. They yielded 3545 cerambycid individuals in 49 species. Species richness was almost identical in old growth and secondary forest; but abundance was higher in old-growth. …
