Stream invertebrates and water temperature : evaluating thermal tolerances in the Cape floristic region (South Africa) - implications of climate change

Ketley, Zoma AnneDepartment of Biological Sciences2009

… an important environmental variable for aquatic invertebrates as it affects their development, reproduction and survival. Temperature also affects the abundance and distribution of individuals in a stream or river. Stream temperatures are affected by human impacts which include not only impacts …

The effects of area and surface complexity on the structure and formation of stream benthic communities

Trush, William J.Virginia Polytechnic Institute and State University1979

Rocks, situated in a stream riffle, can.be interpreted as islands. A sampling of macroinvertebrate communities found on a series of rocks 31 to 1000 cm² in surface area, produced a Log species- Log area curve with a slope of 0.352. This slope could not be compared to Preston’s prediction of a slope …

Predation effects of benthivorous fish on stream food webs – a large scale and long term field experiment

Winkelmann, CarolaTechnische Universität Dresden

… lakes and reservoirs. Thus, the knowledge about stream ecosystems is much more rudimentary than that for lakes in this respect. The aim of this thesis, therefore, was to describe and assess the effects of fish predation in natural stream ecosystems. For that purpose a reach scale field experiment …

Feeding of Hatchery-reared Brown Trout (Salmo trutta L.) In Relation To The Diet In A South Dakota Stream

McCoy, Richard W.

… in October. Two peaks in number of drifting invertebrates occurred at night in the samples for May through September and one peak occurred at night in the October sample. All nighttime peaks were a result of changes in the number of drifting benthic and emergent invertebrates; the presence of …

Integrating GIS with Benthic Metrics: Calibrating a Biotic Index to Effectively Discriminate Stream Impacts in Urban Areas of the Blackland Prairie Eco-Region

Earnest, Steven F. P.University of North Texas2003

… determined from the collection of benthic macroinvertebrates or fish, into a single assessment. This study was conducted in Dallas County Texas, an area located in the blackland prairie eco-region that is semi-arid and densely populated. The objectives of this research were to identify reference …
