“…For example, increased intraspecific competition for food resources has been shown to increase niche width (Svanbäck and Boldnick 2007). Our results support previous findings that the feeding habits of stone loach and bullhead differ from each other and that resource partitioning might be the key factor, which enables coexistence of these two species with apparently similar ecology (Hyslop 1982;Welton et al 1983Welton et al , 1991. The well-defined separation of stone loach and bullhead populations and their similar location in the trophic niche space at both site categories suggests that the presence of crayfish does not markedly change the use of basal food sources.…”

“…Our results indicate that the overall contribution of pelagic food sources to bullhead diet was higher than for stone loach. Bullheads are visual predators and therefore, better suited to capturing zooplankton than non-visual stone loaches (Hyslop 1982;Welton et al 1983). …”

Invasive crayfish are spreading rapidly across Europe, where they are replacing the native crayfish species and impacting negatively on some other biota. Freshwater crayfish and many benthic fishes share similar habitat and food requirements and hence potentially compete for resources. In this study, we investigated impacts of the introduced signal crayfish (Pacifastacus leniusculus) on fish in stony littoral habitats of two large boreal lakes. We compared the littoral fish community composition and the densities of two common benthic fish species between sites with and without crayfish. To evaluate whether signal crayfish share the same food resources as benthic littoral fish or change their feeding habits, we used mixing models and trophic niche estimates based on analyses of stable isotopes of carbon and nitrogen. Both the community composition of littoral fish and the densities of benthic fish species were similar at sites with and without signal crayfish. Even though stable isotope signatures indicated strong dietary overlap between crayfish and benthic fish, the use of food sources and trophic niche widths of fish were not noticeably different between crayfish sites and non-crayfish sites. Our results suggest that, at current densities, the non-native signal crayfish does not have significant impacts on benthic fish in the stony littoral habitats of large boreal lakes.

“…Apart from large trout, there was no other apparent strong territorial effect between other species and usually several coexisted in the same microhabitat patch, including bullhead and stone loach long recognized as potential competitors (Smyly, 1957;Hyslop, 1982;Mann, 1989;Welton et al, 1983Welton et al, , 1991. Various species associations based in similar distribution emerged.…”

Habitat use by the fish assemblages of two chalk streams

Patterns of habitat use by fish assemblages in two chalk streams in southern England were examined to identify species preferences with respect to major habitat gradients. Both study sites although differing in some physical habitat characteristics, mainly channel width, water temperature and instream cover, could be similarly arranged along a continuum extending from erosional to depositional habitats. Twelve fish species were collected from stream surveys conducted during July 1993. The habitat was partitioned into six fish species associations that could be assigned to three habitat guilds: depositional (Barbatula barbatula, Gasterosteus aculeatus and Anguilla anguilla), riffle (Leuciscus leuciscus, Thymallus thymallus and Salmo salar) and generalist (Salmo trutta, Phoxinus phoxinus, Gobio gobio, Cottus gobio, Lampetra planeri and Pleuronectes flesus).At low to moderate densities the different species associations were collected in the same habitat patch, but at higher densities there was a clear tendency to mutual avoidance. In particular, large trout appeared as strong interactors that tended to exclude other species from their territories. We hypothesize that the fish assemblage of the Mill Stream and Bere Stream have partitioned the habitat in such a way as to minimize potential competition.

“…The larvae also form an important component of the diet of adult and particularly nestling riverine birds (Ormerod, 1985;Ormerod & Tyler, 1987) and many fish species (Thomas, 1962;Elliott, 1967;Hyslop, 1982;Welton &al., 1983) whilst the adults are favoured by insectivorous bats (Swift et al, 1985). Agapetus fuscipes Curtis, is a widespread British trichopteran (Rees, 1978) and in common with other grazing trichopterans is important in determining the structural and functional characteristics of the periphyton (Douglas, 1958;Lamberti & Resh, 1983;Jacoby, 1987;Hill & Knight, 1988).…”

The toxicity of cadmium to different larval instars of the trichopteran larvae Agapetus fuscipes Curtis and the importance of life cycle information to the design of toxicity tests

1989

View full text Add to dashboard Cite

The acute toxicity of cadmium to three larval instars (1 st, 3rd and 4th) of the cased trichopteran Agapetus fuscipes Curtis was determined for animals both in the cased and uncased state. First instar larvae were significantly more sensitive than 3rd or 4th instars and for all ages cased animals were more resistant than uncased. Sub-lethal toxicity was demonstrated by a reduction in case building activity and aggregation response. The need to consider life cycle information when designing toxicity tests and the importance of incorporating sub-lethal responses into a study are discussed.
