Stream Macroinvertebrate Response to Clearcut Logging
Why study response of stream invertebrates to watershed disturbances such as clearcut logging? Stream invertebrates can be excellent integrators of changes in such ecosystem phenomena as changes in the food base of ecosystems. For example, a number of invertebrate taxa appear to track changes in food resources (Hawkins et al. 1982; Fuller et al. 1986; Wallace and Gurtz 1986; Feminella and Hawki...
متن کاملDetecting Concept Drift in Data Stream Using Semi-Supervised Classification
Data stream is a sequence of data generated from various information sources at a high speed and high volume. Classifying data streams faces the three challenges of unlimited length, online processing, and concept drift. In related research, to meet the challenge of unlimited stream length, commonly the stream is divided into fixed size windows or gradual forgetting is used. Concept drift refer...
متن کاملRelationships between land use , spatial scale and stream macroinvertebrate communities
1. The structure of lotic macroinvertebrate communities may be strongly influenced by land-use practices within catchments. However, the relative magnitude of influence on the benthos may depend upon the spatial arrangement of different land uses in the catchment. 2. We examined the influence of land-cover patterns on in-stream physico-chemical features and macroinvertebrate assemblages in nine...
متن کاملMacroinvertebrate communities along a third-order Iberian stream
Many studies have tried to elucidate the main factors influencing macroinvertebrate community composition and abundance in streams (e.g. Hart 1992, Dudgeon 1994, Giller & Twomey 1993, Maridet et al. 1998, Tierney et al. 1998, Pardo 2000, Doisy & Rabeni 2001). Considerable attention has been paid to food resources (e.g. Hawkins & Sedell 1981, Cowan & Oswood 1984, Boulton & Lake 1992, Friberg 199...
متن کاملStream Macroinvertebrate Communities in Paired Hemlock and Deciduous Watersheds
Tsuga canadensis (Eastern Hemlock) is a common forest species that is declining throughout its range in the eastern United States because of the invasion of an exotic forest pest, Adelges tsugae (Hemlock Woolly Adelgid). This pest kills infected trees, and over time, infected stands are replaced by deciduous forests. The conversion of forests from hemlock to deciduous species is predicted to im...
