The invasive Round Goby (Neogobius melanostomus) alters macroinvertebrate communities in newly colonized environments throughout the Great Lakes region. I revisited four streams which were examined for Round Goby impacts in 2005 by a former graduate student at Buffalo State College, using the same collection techniques at the same time of year. Gobies appear to have expanded their range since the 2005 assessment. Two of the four streams sampled supported Round Goby populations both in 2005 and 2020, whereas one stream which did not have gobies in 2005 currently has a population. Both streams harboring Round Gobies had lower total invertebrate abundance, taxa richness, and taxa diversity than was reported in 2005. A comparison of current streams with and without gobies did not show any consistent differences in the three metrics examined. Collectively, these results indicate Round Goby continue to expand their distribution and streams with gobies present over the last 15 years appear more impacted by this invasive fish.
