communities of streams associated with aspen and conifer forests: long-term structural change.
The stressed habitats consisting of drifting algae in the Neva estuary were colonized by eurybiotic taxa (chironomids, oligochaetes, hirudineans), locally adapted populations of stenobiotic species of trichopterans
and ephemeropterans, typical of the studied habitat, as well as some recently introduced species of amphipods (Gmelinoides fasciatus, Pontogammarus robustoides).
A larval case of the trichopteran
, Micrasema, a species common in lotic situations, suggests the possibility of moving water in or near the basin early in the development of the peatland.
1, Neotrichia pupa - 1, trichopteran
pupae - 14; COLEOPTERA: Stenelmis sp.
In Missouri and Indiana, lepidopterans were most important in the diet, followed by coleopterans, trichopterans
, and dipterans (Brack and Whitaker 2001).
in a river of the Gran Chaco, Argentina.
In Missouri, the proportion of aquatic insects eaten (dipterans, trichopterans
, and plecopterans) was small but influenced by the lunar cycle (Brack & LaVal 1985).
Ephemeropterans and Trichopterans
are not usual prey items for eastern pipistrelles; however, they dominate the diet when they are found.
In Lake Titicaca, Lake Tanganyika, and Lake Baikal there are pelagic flightless trichopterans
that have adopted the habits of the gyrinid coleopterans, which are very different.
constituted the next highest proportion (4.
This study provides an update to the endemic biota of Arkansas by adding 19 species to the state list, including two fungi, three gastropods, one araneid, two opilionids, two pseudoscorpions, one diplopod, three collembolans, two trichopterans
, one coleopteran, one dipteran and one hymenopteran.
The bats switched to coleopterans, trichopterans
, lepidopterans and a variety of other items during the summer, then again fed on chironomids, including even pupae, in the fall.
