Sericostoma vittatum (Trichoptera) Larvae Are Able to Use Pine Litter as an Energy Source
نویسنده
چکیده
We tested the effect of conditioning time of Pinus sylvestris litter on food consumption and growth of laboratory-reared Sericostoma vittatum larvae. In all cases, larval mass was positively correlated with consumption rates but negatively with growth rates and gross production efficiencies. Conditioning time (4, 8 or 30 weeks) had an effect on feeding rates: they were lowest for the least conditioned pine litter, but no effect of conditioning time on growth rates was observed. Contrary to previous reports on conifer litter use by aquatic detritivores, our results indicate that S.vittatum larvae were able to transform the highly refractory pine litter into secondary production even when it was conditioned for only 4 weeks.

Conversion of leaf litter to secondary production by a shredding caddis-fly
1. The aim of this study was to estimate the amount of leaf litter ingested by the shredder caddis-fly Sericostoma vittatum in a small stream in central Portugal. The study combined field data on population dynamics and laboratory experiments to determine the effect of temperature (9, 12, 15 and 18 C), leaf species (Alnus glutinosa, Castanea sativa, Populus · canadensis and Quercus andegavensis...
متن کاملThe larvae of Sericostoma bergeri Malicky, 1973 and Sericostoma herakles Malicky, 1999 (Trichoptera, Sericostomatidae)
This paper describes the previously unknown larvae of Sericostoma bergeri and S. herakles (Trichoptera: Sericostomatidae) restricted to European Ecoregion 6 (= Hellenic western Balkan). Information on the morphology of the larvae is given, and the most important diagnostic features are illustrated. Sericostoma bergeri and S. herakles can be easily separated from known sericostomatid larvae of E...
متن کاملResource‐allocation tradeoffs in caddisflies facing multiple stressors
The replacement of native forests by exotic tree monocultures, such as those of Eucalyptus, decreases the quality of leaf litter inputs to streams and often reduces riparian cover, which can elevate water temperature. The combined effects of these stressors on the survival and performance of detritivores may be important, as detritivore species loss leads to reduced litter breakdown, a key ecos...
متن کاملVariation and life strategies of the Trichoptera (Insecta) larvae community in a first order tributary of the Paquequer River, southeastern Brazil.
The Trichoptera fauna was sampled in a first order tributary of Paquequer River, in the district of Teresópolis, Rio de Janerio State. Quantitative samples of litter from pools, litter from riffles, sand, and stones were taken on each season from February 1991 to February 1992. The life cycles of common genera were categorized into three groups of biological strategies. The largest group repres...

Biodiversity is under threat by the ongoing global change and especially freshwater ecosystems are under threat by intensified land use, water abstraction and other anthropogenic stressors. In order to monitor the impacts that stressors have on freshwater biodiversity, it is important to know the current state of ecosystems and species living in them. This is often hampered by lacking knowledge...
