Critical oxygen demand in Plecoptera and Ephemeroptera nymphs as determined by two methods

  title={Critical oxygen demand in Plecoptera and Ephemeroptera nymphs as determined by two methods},
  author={Bjorn Nageil and Peter Larshammar and Bj{\o}rn Nagell and Peter Larshammar},
The positions of the critical points on oxygen consumption/oxygen concentration curves and the oxygen levels for 95% sustained survival were compared for water insect nymphs. The influence on the oxygen level for 95% sustained survival of internal changes close to emergence was also studied. Nymphs of Diura nanseni, Taeniopteryx nebulosa (Plecoptera) and Cioeon dipterum (Ephemeroptera) were used. The critical point on the oxygen consumption/oxygen concentration curve and the oxygen level for 95…

Overwintering at low oxygen concentrations in the mayfly Leptophlebia vespertina

Investigation of the survival of L. vespertina (L.) nymphs in three humic forest ponds in southern Norway found that they are both positively phototactic and negatively thermotactic in low oxygen concentrations, coupled with an ability to withstand short-term anoxia.

Are altitudinal limits of equatorial stream insects reflected in their respiratory performance

The results indicate that the ability to oxy-regulate is related to the temperature (altitude) at which species naturally occur, and that the altitudinal limit could not be attributed to absolute short-term physiological tolerance of low temperature and oxygen concentration.

Processing of leaf matter by lake-dwelling shredders at low oxygen concentrations

This study shows that the importance of specific shredder species may shift in case of hypoxia, and species-specific traits regarding oxygen sensitivity may also be influential for distribution patterns of shredders both within and between lakes.

Respiration Rate of Stream Insects Measured in situ Along a Large Altitude Range

The weak community-wide response of respiration to temperature in tropical streams is probably due to full acclimatization of the component species to stable and narrow temperature ranges.

Low oxygen pressure as a driving factor for the altitudinal decline in taxon richness of stream macroinvertebrates

It is suggested that low oxygen availability may limit biodiversity at high altitudes not only in the aquatic, but also in the terrestrial environment.

Vyhodnocení emergence vybraných druhů čeledi Nemouridae (Plecoptera)

This master´s thesis evaluated the intensity, timing and sexual synchronization of emergence in two emergence traps on the water temperature, air temperature and water level of Amphinemura sulcicollis and Nemoura minima in the alpine stream Oberer Seebach.

Ventilation of the body surface by dorso-ventral undulations appears to be an important factor in the maintenance of a high rate of oxygen uptake at low concentrations in Piscicola geometra.

The Respiration of Freshwater Snails

The oxygen consumption of some Danish freshwater snails was studied in relation to varying periods of starvation, varying temperatures, weight of animals and oxygen content of the water to show that some species are able to maintain their consumption with decreasing oxygencontent of theWater to a critical point of oxygen supply.

The Oxygen Consumption of Ephemerid Nymphs from Flowing and from Still Waters in Relation to the Concentration of Oxygen in the Water

The data are best summarized by reference to Fig. 1. An extreme contrast is presented by Cloeon dipterum and Baetis sp. in the relation between oxygen consumption and oxygen concentration in the

Responses of Aquatic Invertebrates to Declining Oxygen Conditions

The results suggest a phylogenetic trend of increasing regulation of aerobic metabolism in response to declining environmental levels as animals acquire structures that effectively insulate their respiring tissue from the habitat.


Substrate selection experiments with E. simulans nymphs revealed an inverse relationship between selection for particle size and oxygen consumption and, the less favourable the substrate, the more work that must be done to gain admittance or to burrow further.

The Oxygen Requirements and Thermal Resistance of Chironomid Larvae from Flowing And From Still Waters

Of the larvae of ten chironomid species, those from streams are much less resistant to anaerobic conditions than those from still water and have a lower thermal resistance than still-water forms.


It is shown that when dosage is inferred from the observed mortality on the assumption that susceptibility is distributed normally, such inferred dosages, in terms of units called probits, give straight lines when plotted against the logarithm of their corresponding observed dosages.
