“…High proportions of Tanypodinae automatically reduce the proportions of other taxa, even if their densities have not changed. In addition, however, Tanypodinae are usually considered to be predatory taxa, although few are obligate carnivores (Roback, 1969;Oliver, 1971;Baker and McLachlan, 1979;Walker et al, 1985). Ablabesymia and Thienemannimyia group make up the bulk of the tanypods at Hawes Water, and Darby (1962), Roback (1969), Baker and McLachlan (1979) and Merritt and Cummins (1996) consider these to be essentially carnivorous, including in their diet other chironomids; other material may be exploited when prey items are scarce.…”

This paper presents the results of a high-resolution Late-glacial chironomid stratigraphy from Hawes Water, a small carbonate lake in northern Lancashire. The samples were from a core taken from the terrestrialised margin of the present lake, which represents an intermediate depth between the true littoral and the profundal. The chironomid assemblage showed a high degree of sensitivity to both broad-scale and short-term temperature changes. Comparison with an existing proxy temperature record ( 18 O) for the site confirmed the presence of four temperature inversions within the Late-glacial Interstadial. A mean July air temperature inference model, derived from acid, soft-water lakes in Norway and Svalbard, was applied to the data. Despite the absence of carbonate lakes within the Norwegian training set, there was a close similarity between trends in estimated July air temperature and the 18 O trace, with a particularly strong correspondence in the periods of clay deposition. This suggests that this model is highly robust. The inferred maximum Interstadial temperature was 13.4 C, dropping initially to 7.5 C in the Loch Lomond Stadial. Temperatures reach a maximum of nearly 10 C in this period, cool for a short period before rising rapidly to 13.2 C at the start of the Holocene. These temperatures are similar to but slightly higher than those estimated for Whitrig Bog, southeast Scotland, and lower than those inferred from coleopteran-based models for sites in South Wales.

“…Indeed, this genus is classified as a predator in temperate regions but in this study we classified it as omnivorous. Some diet analysis concluded that, under certain conditions, species of Chironomidae may utilize a wider range of trophic resources (Baker & McLachlan, 1979;Motta & Uieda, 2004;Galizzi et al, 2012;Saito & FonsecaGessner, 2014;Butakka et al 2014). Our results pointed out that, because of its wide trophic spectrum, Monopelopia sp.…”

ABSTRACT. Functional classifi cation of animals is necessary to enhance the predictive power of food web models. However, while there is a large database for functional classifi cation of benthic invertebrates (Functional Feeding Groups, FFG) in the temperate zone, the attribution of individual species of riverine invertebrates is still in its infancies in the Neotropical Region. Diff erent authors hypothesized that diet breadth was larger in the Tropics, however detailed analyses are scarce. In the present study we aimed at classifying dominant benthic taxa of the Middle Paraná River fl oodplain (Argentina) into trophic guilds by diet and niche overlap analysis. We sampled twelve taxa of benthic invertebrates from a fl oodplain lake during low water season and performed a gut content analysis as a baseline for FFG classifi cation. We also used available diet information of other common taxa for statistical analysis. Then, we compared the variance of niche overlap, using Pianka's index, with that of simulated null model. After that we grouped taxa using Morisita similarity index with a threshold of 0.6 and compared niche overlap with null models within and between FFGs. Observed variance of niche overlap was greater than expected by chance, confi rming the presence of FFGs among analyzed taxa. Considering trophic similarity of species, we identifi ed four FFGs: collectors, omnivores, herbivores and predators. Niche overlap was greater than expected by stochastic null models within FFGs, and smaller between FFGs. Nearly one third of analyzed taxa were classifi ed in a diff erent FFG than their congeners of the Holarctic region. This result indicates that classifi cations performed in the Holarctic region should be used with care in the Neotropical region, even in subtropical systems.

“…are known to be predators (KONSTANTINOV, 1968cited in MOLLER PILLOT, 1984MONAKOV, 1972;TITMUS and 8ADCOCK, 1981). However, although Proc/adius has a preference for Tubiflcidae, it uses a large range of food items, the most important of which appears to be detritus (BAKER and McLACHLAN, 1979). Because chironomid densities in both reservoirs were similar, the difference in availability of Tubificidae had no influence.…”

Long-term changes in distribution and taxonomic composition of chironomid larvae and oligochaetes in two water storage reservoirs in The Netherlands were studied. A succession among the chironomid spe-9 was observed. In the last 10-15 years chironomid densities varied. Compared with other lakes chironomid densities were high. Densities of chironomids were higher in the littoral zone than in the profundal zone. The opposite was found for oligochaetes. Densities and composition of the chironomid fauna in the two reservoirs were similar. Proc/adius, Tanytarsus and Harnischia dominated at all depths. However, pupal exuviae samples showed some differences in chironomid taxonomic composition between the two reservoirs. Orthocladiinae, rarely found in bottom samples, abounded in pupal exuviae samples.
