Why PhD theses...

PhD thesis is the result of years of hard work.

keyword researchMeasured by download count PhD theses are one of the most popular items world wide on open access repositories. But unless a thesis is published, it is very difficult for other researchers to find out about it and get access to it. Theses are often under-used by other researchers. Thesica.org attempts to address this issue by making it easy to identify and locate copies of many theses in various disciplines.

ABSTRACT

The thesis describes the community composition, population structure and dispersal in a lowland rainforest community, extended to changes in butterfly composition along an altitudinal gradient. It tests the feasibility of mark-release-recapture studies in the understories of lowland primary forests, describes dispersal in relation to host plants and compares dispersal and demographic parameters with temperate species. Focusing on primary as well as secondary sites the thesis analyzes species richness and similarity between sites along an altitudinal gradient. It also tests ecological correlates for endemism in New Guinea butterflies, particularly their geographic and altitudinal range, as well as their optimum altitude.
