“…Also, at seasonal scale, the spatial distribution of foragers could be strongly influenced by behavioral differences. Freeman and Grossman (1993) found that rheophilic cyprinid foragers aggregate during July, October, and/or December, but spread out during other months.…”

“…Elsewhere, the concept of complementation, while not explicitly mentioned, can be seen in studies where the importance of habitat configuration is recognized, especially in restoration strategy (Pedroli et al 2002;Rosenfeld & Hatfield 2006). Another research project examined the role of the proximity of two different habitats for rosyside dace (Clinostomus funduloides, Freeman & Grossman 1993).…”

To fill the gap between microhabitat and landscape scale habitat models for freshwater fish, it is becoming increasingly common practice to adopt a continuous view of riverscapes, thus allowing a better understanding of the processes in place at the river management level (segments of 1À100 km). The aim of this study was to test the effects of the spatial structure of habitat on fish distribution at this scale. Inferred habitat relationships were generated using spatial metrics adapted from landscape ecology. These were calculated for two species of multi-habitat cyprinid fish in a 25-km long segment of the Seine River. A spatially continuous survey was then designed to acquire fish sampling data relating to the riverscape. Explanatory models were devised to quantify the extent to which environmental and spatial variables could describe fish distribution patterns. Spatially continuous sampling of feeding habitats at dawn and dusk provided greater understanding of the spatial distribution of common barbel (Barbus barbus, L.) and nase (Chondrostoma nasus, L.). Fish observations were aggregated longitudinally in neighboring feeding habitat patches, with the highest abundance found in patches with the best local conditions. The species were present for large feeding patches, as well as for a higher proximity index for those patches. This result emphasized the importance of the supplementation of feeding habitats. By quantifying spatial habitat relationships using spatial metrics, it was possible to identify the best suited configuration of functional habitats to the needs of shoals. At present, most conservation work focuses on restoring local habitats. There is also growing interest in large-scale fish management, which has been encouraged by the advent of metapopulation theory. This study highlights the need for greater work at a third, intermediate scale that is no less significant: restoring daily and seasonal movements between functional habitats.

“…The biological importance of accurate delineations of the type, location and extent of habitat features has been recognized by a number of investigators in river systems (Fausch and White, 1981;Southall and Hubert, 1984;Lobb and Orth, 1991;Rinne, 1991;Addley, 1993;Freeman and Grossman, 1993;Rabeni and Jacobson, 1993;Bovee et al, 1994;Stanford, 1994). In fact, the delineation of the contact zone between two (or more) habitat types as a spatial metric or attribute may constitute a unique habitat type in itself (Ranney et al, 1981;Noss, 1983;Lovejoy et al, 1986;Harris, 1988;Yahner, 1988;Malcolm, 1994).…”

“…For example, in small, steep gradient riffle-pool mountain streams in the Southern Blue Ridge Mountains, very specific sediment and flow conditions are necessary for providing foraging area to the Rosyside dace Clinostomus funduloides (Freeman and Grossman, 1993). These fish forage in specific areas that contain a combination of fine-grained depositional bars in low velocity eddies adjacent to high velocity currents (Freeman and Grossman, 1993). Flow alterations, which are often accompanied by changes in velocity and sediment dynamics, can be detrimental to specific habitats such as these and influence site foraging availability.…”
