The macrophytic vegetation of the River Tees in 1975: observed and predicted changesFreshwater Biology - Tập 7 Số 1 - Trang 43-60 - 1977
Nigel Holmes, Brian A. Whitton
SUMMARY. An account is given of the distribution of macrophytes in the River Tees and its tributaries, north‐east England, together with a critical discussion of the problems involved in recording data in a form which can be used for monitoring long‐term changes of vegetation in rivers. Among the conventions and methods adopted in the present study are an attempt to...... hiện toàn bộ
A fuzzy coding approach for the analysis of long‐term ecological dataFreshwater Biology - Tập 31 Số 3 - Trang 295-309 - 1994
François Chevenet, SYLVAIN DOLÉADEC, Daniel Chessel
SUMMARY
We present an unconventional procedure (fuzzy coding) to structure biological and environmental information, which uses positive scores to describe the affinity of a species for different modalities (i.e. categories) of a given variable. Fuzzy coding is essential for the synthesis of long‐term e...... hiện toàn bộ
Spatial and temporal impacts of a diesel fuel spill on stream invertebratesFreshwater Biology - Tập 46 Số 5 - Trang 693-704 - 2001
David A. Lytle, Barbara L. Peckarsky
1. We assessed the effects of a 26 500 L diesel fuel spill on the macroinvertebrate fauna of a small trout stream in central New York, U.S.A. To determine the spatial extent of the spill we sampled three locations (0.7, 5.0 and 11.8 km downstream of the spill), each containing a reference site (unaffected tributary) and an impact site (downstream of spill). Sampling was repeated four times...... hiện toàn bộ
The turbulent boundary between water science and water managementFreshwater Biology - Tập 24 Số 1 - Trang 201-209 - 1990
Peter Cullen
SUMMARY. 1. It is common to observe friction between limnologists and the managers of water resources. This is often a result of misunderstandings about the cultures within which each works.2. There are a number of ways that science can contribute to effective management of water resources, but limnologists must appreciate that there are value quest...... hiện toàn bộ
Classification of natural flow regimes in Australia to support environmental flow managementFreshwater Biology - Tập 55 Số 1 - Trang 171-193 - 2010
Mark J. Kennard, Bradley J. Pusey, Julian D. Olden, Stephen Mackay, Janet Stein, Nick Marsh
Summary1. The importance of hydrologic variability for shaping the biophysical attributes and functioning of riverine ecosystems is well recognised by ecologists and water resource managers. In addition to the ecological dependences of flow for aquatic organisms, human societies modify natural flow regimes to provide dependable ecological services, including water ...... hiện toàn bộ
