THE EFFECT OF PHORATE ON WETLAND MACROINVERTEBRATES

Environmental Toxicology and Chemistry, 1996
Abstract The effects of phorate, an organophosphorus insecticide, on aquatic macroinvertebrates was studied in littoral mesocosms in South Dakota wetlands. In 1991 and 1992, four mesocosms were constructed in each of three wetlands. In each wetland, one mesocosm was a reference and phorate concentrations of 1.2, 2.4, and 4.8 kg/ha were ...

Classification and retrieval on macroinvertebrate image databases

Computers in Biology and Medicine, 2011
Aquatic ecosystems are continuously threatened by a growing number of human induced changes. Macroinvertebrate biomonitoring is particularly efficient in pinpointing the cause-effect structure between slow and subtle changes and their detrimental consequences in aquatic ecosystems.

Reintroduction of freshwater macroinvertebrates: challenges and opportunities

Biological Reviews, 2018
ABSTRACTSpecies reintroductions – the translocation of individuals to areas in which a species has been extirpated with the aim of re‐establishing a self‐sustaining population – have become a widespread practice in conservation biology. Reintroduction projects have tended to focus on terrestrial vertebrates and, to a lesser extent, fishes.

Macroinvertebrates as Indicators of Pollution

Journal AWWA, 1977
Macroinvertebrates are a useful indicator of water‐quality changes such as those caused by the introduction of pollutants that affect these organisms.

Waldo Lake Macroinvertebrates

Lake and Reservoir Management, 2000
ABSTRACT A total of 41 taxa was collected from nearshore and offshore habitats in Waldo Lake. The highest taxonomic diversity occurred in nearshore habitats which were structurally more complex and heterogenous than offshore habitats. The presence of 39 taxa (Hydridae excluded) in nearshore habitats varied by habitat-type and taxonomic group.

Macroinvertebrates in Reed Litter

International Review of Hydrobiology, 2001
Stem and leaf litter of Phragmites australis were enclosed in litter bags and submerged in a vigorous and a die-back reed stand of Lake Ferto/Neusiedler See (Hungary). Species composition and individual number of the macroinvertebrates within the litter bags were recorded between April, 1996 and July, 1998. Thirty one taxa were found during the two and

Macroinvertebrates of Inland Waters

2020
The term ‘macroinvertebrates’ has both taxonomic and physical connotations. Conventionally, many biologists use the term to solely include arthropods, although other taxa—notably molluscs and larger annelids—are also well-represented in freshwater environments. All these groups are diverse, and vulnerable to changes.

Microhabitats and macroinvertebrates: Logjam influences on stream morphology and macroinvertebrate traits

Logjams are important hydrologic features that shape stream channel morphology and create habitat for organisms. In this lesson, students learn about and measure logjams in a wadeable stream and predict how logjams affect macroinvertebrate communities.
