1. Macroinvertebrate communities were studied from 1994 to 2001/2002 (except 1997) in six streams in Denali National Park, interior Alaska. All six streams were potential reference streams with no known impairment. 2. Abundance of individual taxa varied markedly from year to year. Overall, abundance decreased over the study period, particularly wit...

Macroinvertebrates were collected from riffles in six reference streams in Denali National Park and Preserve, Alaska every year from 1994 to 2001. Two of the streams were also sampled in 2002. The most persistent taxon was Baetis, but its abundance varied markedly from year to year, ranging from < 50 m-2 to nearly 2000 m-2. Rank abundance of the 10...

... The effect of permafrost thaw slumps on the chemical and physical habitat of streams has a high potential to impact instream processes. For example, benthic macroinvertebrate communities are used extensively to monitor change in freshwater ecosystems (Wallace and Webster 1996;Milner et al. 2006; see review in Buss et al. 2014, Moquin et al. 2014 because they show functional and structural responses to changes in water quality (Buss et al. 2014). Increased sediment loads from slump debris can have multiple impacts on macroinvertebrate communities including changes in habitat structure through the filling of interstitial spaces on the streambed (Lenat et al. 1981;Lemly 1982) or loss of food resources such as benthic algae (Levenstein et al. 2018). ...
