Photoresponses of Chaoborus larvae

Journal of Insect Physiology, 1980
Abstract The diel vertical migration of Chaoborus larvae is a well known phenomenon. In order to quantify the ability of larvae to utilize underwater light cues in their migration, we measured photoresponses of fourth-instar Chaoborus punctipennis larvae in the laboratory.

Photoresponses of second-instar Chaoborus larvae

Journal of Insect Physiology, 1982
Abstract The diel vertical migration of Chaoborus larvae varies with larval instar. Although light is involved in the control of vertical migration the contribution of larval photoresponses is unknown. In order to describe ontogenetic changes in larval photoresponses we measured photoresponses of second-instar Chaoborus punctipennis larvae in the

Nickel dynamics in the lakewater metal biomonitor Chaoborus

Aquatic Toxicology, 2010
Nickel (Ni) is a widespread contaminant present at toxic concentrations in aquatic systems in the vicinity of some mining and smelting operations. However, its accumulation by aquatic animals has been little studied and there are few biomonitors for this metal.

Ecological energetics of Chaoborus in a tropical lake

Oecologia, 1986
Ecological energetics of Chaoborus brasiliensis from Lake Valencia, Venezuela, were studied between February 1979 and February 1980. Direct measurements were made of the respiration rate, assimilation efficiency, and growth rate of all 4 larval instars and of the pupae.

COMPARATIVE BIOLOGY OF CHAOBORUS AMERICANUS AND CHAOBORUS TRIVITTATUS IN EUNICE LAKE, BRITISH COLUMBIA1

Limnology and Oceanography, 1972
Larval morphology, growth (length and weight), and vertical distribution were studied in populations of Chaoborus (C.) americanus (Joh.) and Chaoborus (Schadanophasma) trivittatus Sacther in Eunice Lake, British Columbia, during 1970–1971, with additional samples from summers of 1967 and 1969.

Do Chaoborus larvae migrate in temporary pools?

Hydrobiologia, 1984
A diurnal vertical migration of larvae of Chaoborus punctipennis (Say) was observed in shallow temporary woodland pools in East Texas. In the laboratory, in 153 cm tall columns, the larvae underwent a much greater migration than possible in the shallow pools.

Chaoborus flavicans (Díptera) is an oxy-regulator

Fundamental and Applied Limnology, 2002
The respiration rates of Chaoborus flavicans instar IV were measured in a flow-through respirometer at oxygen concentrations between 5 % and 100 % saturation at an experimental temperature of 20 °C. The respiration rate of the instar IV followed a hyperbolic function with the critical point at an oxygen saturation of 15 %. Thus, C.

Identification of Chaoborus kairomone chemicals that induce defences in Daphnia

Nature Chemical Biology, 2018
Infochemicals play important roles in aquatic ecosystems. They even modify food web interactions, such as by inducing defenses in prey. In one classic but still not fully understood example, the planktonic freshwater crustacean Daphnia pulex forms specific morphological defenses (neckteeth) induced by chemical cues (kairomones) released from its ...
