Abstract
Peninsular Malaysia has rich and diverse flora and fauna. Much of these have
yet to be documented. The avifauna is an important group that has received little
attention, ecologically in this country. Different approaches of diversity
measurements are presented in this thesis in order to evaluate the bird diversity in
natural and man-made habitats. The objectives of this study are to determine the
current bird species composition and diversity, to analyse β-diversity of birds, to
investigate patterns of rarity among birds in natural habitats, and to study the
contribution of rice fields to the bird diversity in Peninsular Malaysia by using
multiple diversity measurements. The presence/absence data were obtained from
primary (2002-2013) and secondary sources (1992-2015) recorded from 53 sites of
natural habitats. Primary and secondary of bird data were also collected since year
2013-2014 from 83 sites of rice fields in nine states, Peninsular Malaysia. Point
counts and mist-netting methods were used for bird census. Species accumulation
curve was plotted to describe the species composition of birds. Seven species
estimators were performed to estimate the current bird species richness and evaluate
estimators’ performance. The β-diversity was described through calculation of
variation, turnover, and taxonomic similarity. The pattern of rarity among forest
birds were determined by using Rabinowitz’s seven forms of rarity. Meanwhile the
contribution of rice fields on the total bird species in Peninsular Malaysia was
analysed by using taxonomic distinctness measures. Four hundred and thirty eight
bird species were recorded from 53 sites of study areas. The MMMeans estimated
482 bird species for natural habitats of Peninsular Malaysia. The β-diversity analysis
showed that bird diversity was negatively correlated with distance but positively
influenced by elevation,
