1. Growth, Production, and Community Composition of Fishes Inhabiting a First‐, Second‐, and Third‐Order Stream of Eastern Kentucky

Author:

Subject:
aquatic invertebrates; biomass; community structure; detritus; energy; fish; fish communities; mathematical theory; microhabitats; primary productivity; streams; summer; Kentucky
Abstract:
... Fish populations in a first—order, a second—order, and a third—order stream were studied during the summers of 1967—68. The primary food of each fish species was determined. Available food sources included terrestrial invertebrates, aquatic primary production, aquatic invertebrates, aquatic vertebrates, and detritus. Average daily growth rates showed that age—group I fish of most species grew fast ...

Abstract:
... We examined the patterns of distribution of species of resident fishes in an experimental habitat consisting of 10 small live colonies of the coral Acropora pulchra (L—units), and 10 similar sized pieces of eroded coralline rock (D—units). Approximately every 4 mo for 2 yr, all fish in each unit were collected. Numbers collected were similar at all times to numbers in control units that were not d ...

Abstract:
... Seasonal fluctuation of water level is the most critical environmental factor affecting the fish community of the Everglades marshes. During a 27—mo period of water—level stability, fish density decreased but biomass, average size of fish, species richness, and species diversity increased. These changes were accompanied by a functional shift from the dominance of small sized omnivorous species to ...

When young P. flavicauda recruit into the habitat where P. wardi are most num ...

Abstract:
... The fishes in Lower Putah Creek, a regulated stream in the Central Valley of California, were sampled over a 5‐yr period, 1994–1998. Distinct fish assemblages were observed in the lower 37 km of stream using two‐way indicator species analysis (TWINSPAN) and canonical correspondence analysis (CCA). The assemblages segregated in an upstream‐to‐downstream manner. Distinct differences were found betwe ...

Abstract:
... Physical, chemical, and biological data collected on the Labrador Shelf in September 1985 are used to examine a hypothesis that the nutrient influx from Hudson Strait increases primary production on the northern shelf and this supports a "conveyor belt" food chain as the community is transported southward by the mean circulation. This hypothesized influx of production was proposed to account for t ...

Abstract:
... Natural and anthropogenic perturbations do not always equally affect all parts of an ecosystem, and all parts of an ecosystem do not equally contribute to maintain fish communities. The increasing pressure to use natural resources and to modify habitats led to the development of approaches to identify areas of key importance for fish communities. Following these approaches, aquatic systems could b ...

Abstract:
... Conserving biological resources native to large river systems increasingly depends on how flow‐regulated segments of these rivers are managed. Improving management will require a better understanding of linkages between river biota and temporal variability of flow and instream habitat. However, few studies have quantified responses of native fish populations to multiyear (>2 yr) patterns of hydrol ...

Abstract:
... We explored the recent (1969–1996) dynamics of fish communities within Lake Erie, a system formerly degraded by eutrophication and now undergoing oligotrophication owing to phosphorus abatement programs. By merging bottom trawl data from two lake basins of contrasting productivity with life‐history information (i.e., tolerances to environmental degradation, diet and temperature preferences), we ex ...

However, experimental manipulation of the habitat provides a more unequivocal estimate of its importance. In this study we quantified how fish communities on small patch reefs covaried with changes in benthic cover habitat features. A random sample of sm ...

A Procrustean approach was employed to ass ...

Accordingly, feeding ecology and habitat use were studied in native whitefish (Coregonus lavaretus) and recently invading vendace (C. albula) in two lake localities sit ...
