| Summary: | 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.).
