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.

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.

The Role of Macroinvertebrates in Stream Ecosystem Function

Annual Review of Entomology, 1996
This review focuses on some of the roles of macroinvertebrate functional groups, i.e. grazers, shredders, gatherers, filterers, and predators, in stream-ecosystem processes. Many stream-dwelling insects exploit the physical characteristics of streams to obtain their foods.

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.

Monitoring Freshwater Macroinvertebrates

2020
That invertebrate assemblages and individual species respond, often in predictable ways, to numerous changes their environments, gives them enormous value in assessing and predicting changes in water quality, impacts of disturbances, and the resources needed to sustain diversity and functions.

Macroinvertebrates: Composition, Life Histories and Production

2008
This chapter describes the composition of the macroinvertebrate fauna of tropical streams, especially the insects, with the aim of uncovering the patterns in diversity and richness that they exhibit. It reveals that insects and other tropical macroinvertebrates are sometimes affected by temperature, but that flow regime and habitat stability have a ...
