The lotic communities in Ovre Heimdalen were completely dominated by insects. The species distribution of stoneflies (Plecoptera), mayflies (Ephemeroptera) and caddisflies (Trichoptera) is given together with autecological notes on the Plecoptera and certain other major species. The species distribution of these groups, especially the Plecoptera, was clearly related to the deciduous vegetation along the streams. There was a reduction in species parallel to a reduction in Salix vegetation… Expand

Figures from this paper

The Plecoptera of Øvre Heimdalsvatn
TLDR
During the winter N avicularis occurred in large numbers on soft bottom at nearly all depths while D. bicaudata was only recorded on stony substratum in shallow water and was therefore more susceptible to predation and was recorded in trout stomachs during most of the year. Expand
The fauna of the exposed zone of Øvre Heimdalsvatn: Methods, sampling stations and general results
TLDR
Densities of G. lacustris, Ephemeroptera, Tipulidae and Plecoptera showed a positive correlation with detritus, and no significant relationship was found for the other taxa. Expand
The lake ecosystem of Ovre Heimdalsvatn
TLDR
On account of the long period of ice cover and the rapid rise in temperature after ice break, many organisms (both planktonic and benthic) showed synchronous development. Expand
Life cycle of Chaetopteryx villosa (Fabricius, 1798) (Trichoptera: Limnephilidae) in a lowland‐ and a mountain‐stream in western Norway
TLDR
Chaetopteryx villosa is a common species in west Norwegian streams and rivers, ranging from sea level up to about 1250 m a.s.l. in lowland areas the species is univoltine, overwintering as eggs during the first winter and in the fourth and fifth instars during the second winter. Expand
City Channel Chironomids—Benthic Diversity in Urban Conditions
The study focuses on the diversity of urban channel chironomids (the Aa River, the City of Munster, North-western Germany), initially intended as a proxy of habitat structure. Three ecological keyExpand
Life cycle shifts in Baetis rhodani (Ephemeroptera) in the Norwegian mountains
TLDR
Although larval growth and voltinism were influenced by water temperature, other factors such as food resources are likely to be important in mountain areas because of the widely distributed mayfly's success in colonising a wide range of running water habitats throughout Europe. Expand
New records of Norwegian Coleoptera 11 : Species new to the fauna and notes on some little known species
The mayfly Baetis digitatus is recorded from Norway for the first time. The nymphs of this species have been collected at several localities in the large lowland river, Drammenselva, and two of itsExpand
Ecology of glacier-fed rivers: current status and concepts
SUMMARY 1. This paper is an introduction to a special issue of Freshwater Biology containing papers dealing with various aspects of the ecology of glacier-fed rivers. 2. Using similar fieldExpand
The energy budget of the brown trout population of ovre Heimdalsvatn
TLDR
The specific energy value of trout increased with increasing weight of the fish, and an energy decrease of almost 50% was demonstrated for the spawning trout of both sexes, and the calorific values prior to spawning were not reached before the next summer. Expand
A long-term study of catchment inputs of 137Cs to a subalpine lake in the form of allochthonous terrestrial plant material
The input of allochthonous plant material, largely terrestrial in origin, during the spring spate is a major source of primary production for montane lake ecosystems such as Øvre Heimdalsvatn and isExpand

The Ephemeroptera of Øvre Heimdalsvatn
TLDR
All species were univoltine, but differences in ability to grow during ice cover and in life cycle timing resulted in a succession in emergence during the ice free period. Expand
The Trichoptera of Øvre Heimdalsvatn
TLDR
Trichopteran larvae were sampled on soft substrata at all depths, on stony substrata in the exposed zone, and the adults in emergence traps, placed along the lake shore, where the two most numerous species showed different habit preferences. Expand
Life cycles of benthic insects in Lapland streams (Ephemeroptera, Plecoptera, Trichoptera, Diptera Simuliidae)
A large material of larvae and nymphs of Ephemeroptera, Plecoptera, Trichoptera and Diptera Simuliidae from lotic biotopes in Lapland streams was used for an analysis of life cycle patterns.Expand

The effect of temperature on the egg incubation period of Taeniopteryx nebulosa (Plecoptera)
TLDR
A relationship, linear on logarithmic scales, was found between water temperature and mean egg incubation period for the temperature range 2 to 240C for Taeniopteryx nebulosa. Expand
Structure and Function of Stream Ecosystems
TLDR
There is a need to identify functional groups of organisms, at least partially independent of traditional taxonomic determinations, in order to address important process-oriented ecological questions. Expand
