Benthic insect diversities can indicate how much anthropogenic activities affect a certain area. Catanduanes, known for its agriculture, led to the prominence of agriculture related anthropogenic disturbances in the province. Observing the diversity of these significant benthic insect species through a rapid diversity assessment among affected streams will determine whether there is a stark difference between relatively disturbed downstream areas and their rarely disturbed upstream areas. Benthic insects located in the downstream and upstream areas of the streams of Sto. Niño and Sibanhan were simultaneously sampled one day each through pole kick net capturing, wherein these samples equated to a rough estimate of the total abundance and diversity of the benthic insects within...Read More
