Factors Affecting Foraging Patterns of Juvenile Bluegill (Lepomis macrochirus) in Vegetated Habitats of a Wisconsin Lake

Mechanical and energetic factors underlying gait transitions in bluegill sunfish (Lepomis macrochirus)

“…A number of studies have investigated bluegill foraging preferences and efficiency (Mittelbach, 1981;Werner et al, 1981;Devries et al, 1989;Harrell and Dibble, 2001), and bluegills are attracted to structurally complex habitats such as weed beds (Johnson, 1993). These are rich sources of the invertebrates that constitute much of the bluegill's diet (Beckett et al, 1992).…”

Influence of aquatic macrophyte habitat complexity on invertebrate abundance and richness in tropical lagoons

“…Aquatic macrophytes have been considered key components of habitat in aquatic environments, because of their importance as a food source (Duarte, Planas & Peñuelas, 1994; Poi de Neiff & Casco, 2003) and their role in increasing the structure (and thus the habitat complexity) of a waterscape. Indeed, an increase in taxon richness and density of both fish (Dibble, Killgore & Harrel, 1996; Harrel & Dibble, 2001; Pelicice, Agostinho & Thomaz, 2005) and invertebrates (Lansac‐Tôha, Velho & Bonecker, 2003; Rennie & Jackson, 2005) has been recorded inside plant beds. Fractal geometry has been frequently used to measure the role of plant complexity on invertebrate richness and density in marine habitats (e.g.…”

Spatio-Temporal Segregation of Cladocerans within aChara hispidaBed

“…A combination of various predators, which naturally occur in freshwater systems, may directly alter the habitat segregation of zooplankton species since they also selectively choose certain macrophyte species for food, shelter, and nursery areas (Petr 2000, Harrel andDibble 2001). Fish often tend to feed on zooplankton with preferences increasing as a function of zooplankton body size, regardless of taxonomic identity (Hambright and Hall 1992), so large individuals are captured more often than those of smaller body size.…”
