| description | The plausible effect of seasonal change (wet and dry) on the structure of aquatic insect
community was investigated at rivers in Belum-Temengor Forest Complex (BTFC), Perak,
Malaysia. The amount of rainfall received was considered as seasonal changes in the tropical
regions. The rivers were visited twice in dry and wet seasons to sample aquatic insects using
rectangular aquatic nets. Their abundance and richness varied significantly between both dry
and wet seasons (P = 0.000; Mann-Whitney U test). More aquatic insect was collected in dry
seasons (17,633 individuals) compared to wet seasons (6,542 individuals). The aquatic insect
abundance decreased tremendously during the wet seasons (45% reduction) and diversity
showed fewer species richness in the wet season (98 genera) compared to the dry season (114
genera). The most affected taxa caused by the heavy water flow were Ceratopsyche sp. (family
Hydropschidae and subfamily Limoniinae which huge reduction in density occurred during the
wet season. Water temperature, BOD3, DO and COD were significantly different between
seasons (Kruskal Wallis test, P < 0.05). The presence of phosphorus and ammonia-nitrogen in
water during dry season had major influence on the aquatic insect composition while rainfall
was the main factor that regulated the insect communities in wet seasons. |
