    Abstract

    Pembukaan hutan untuk aktiviti ekonomi menyebabkan kemusnahan habitat semulajadi dan degradisi fungsi ekosistem. Kepelbagaian dan komposisi organism selalunya terkesan secara negatif akibat pembukaan tanah. Peluasan kawasan perladangan seperti ladang kelapa sawit, getah dan ladang pokok balak (Cth: Jati, Pinus dan Araucaria) memberi ancaman yang lebih besar kepada hutan semulajadi kita. Anai-anai sebagai agen pengurai bahan organik utama dalam ekosistem hutan tropika juga mengalami kesan akibat ganguan pada habitat mereka. Kajian yang dijalan ini bertujuan untuk mengkaji struktur komuniti anai-anai di kawasan-kawasan terpilih dengan jenis guna-tanah dan gangguan yang berbeza. Gangguan pada hutan didapati mempunyai kesan negatif terhadap kepelbagaian anai-anai. Penurunan kepelbagaian species anai-anai dapat dilihat apabila tahap gangguan meningkat daripada hutan primer (purata: 16.5 sp.) > hutan sekunder (purata: 15.5 sp.) > hutan dengan binaan (purata 13.5 sp.) > hutan ladang (purata: 6 sp.). Forest conversion causes the destruction of natural habitat, fragmentation and degradation of an ecosystem functioning. Diversity and assemblages of organisms are often negatively affected by the land conversion. The expansion of plantation forest such as oil palm, rubber tree and forest plantations (e.g. Teak, Pinus and Araucaria) inflicts a greater threat to our natural forest. Termites as the main decomposer of organic matter in the tropical forest ecosystem are very much affected by the disturbances in their habitat. The present study was conducted mainly to investigate the community structure and assemblages of termites in the selected sites with different type of land-use and disturbances. Forest disturbance was found to have negatively affecting termite diversity and assemblages. The general trend of declining pattern of species richness can be observed along the increasing disturbance gradient of Primary forest (ave: 16.5 sp.) > Secondary forest (ave: 15.5 sp.)> Disturbed forest with building (ave: 13.5 sp.) > Plantation forest (ave: 6 sp.).
