| distribution pattern of black fly (diptera: simuliidae) assemblages along an altitudinal gradient in peninsular malaysia. | preimaginal black flies (diptera: simuliidae) are important components of the stream ecosystem. however, there has been limited research undertaken on the vertical distribution of preimaginal black flies and their associated ecological factors. stream conditions are generally variable along the altitudinal gradient. therefore, we conducted an in-depth entomological survey to investigate the simuliid distribution pattern along an altitudinal gradient in peninsular malaysia. | 2016 | 27094088 |
