Aquatic Invertebrates as Indicators of Stream Pollution

Using Aquatic Macroinvertebrates as Indicators of Stream Flow Duration

Aquatic Invertebrates

Animals are important and conspicuous elements inPacifi c Island ecosystems. They are crucial to the fl ow of energy and nutrients within ecosystems and they strongly infl uence, and in some cases control, the species composition and population structure of communities. Determining which animal species are present in an area and what they do is crucial to understanding how ecosystems function a...

Aquatic Invertebrates as Unlikely Vectors of Buruli Ulcer Disease

Buruli ulcer is a necrotizing skin disease caused by Mycobacterium ulcerans and associated with exposure to aquatic habitats. To assess possible transmission of M. ulcerans by aquatic biting insects, we conducted a field examination of biting water bugs (Hemiptera: Naucoridae, Belostomatidae, Nepidae) in 15 disease-endemic and 12 non-disease-endemic areas of Ghana, Africa. From collections of 2...

Endocrine Disruption in Aquatic Invertebrates

Effects of High Levels of Antimycin A on Aquatic Invertebrates in a Warmwater Arizona Stream

—Restoration of native fish to freshwater habitats often requires nonnative fish removal via chemicals such as antimycin A. Despite widespread use, there are limited field studies quantifying the effects of antimycin A on aquatic macroinvertebrates. We studied the immediate and short-term effects of antimycin A on macroinvertebrates during a fish renovation project in Fossil Creek, Arizona. We ...
