Metabolic expenditures in Chaoborus larvae1

Limnology and Oceanography, 1980
The energy consumption of 4th instar larvae of Chaoborus trivittatus of two different ages was determined in a respirometer. Measurements included energy consumption of fed larvae at 13° and 21°C, as well as an estimate of the cost of process: ng food or specific dynamic action (equals the metabolic rate of starved larvae × 0.369).

Chaoborus behavioural responses to changes in fish density

Fundamental and Applied Limnology, 1999
The response of Chaoborus to biomanipulation-induced changes in fish community structure was studied in two small south-central Ontario lakes which had similar physical and chemical characteristics. The biomanipulation involved: (a) three years (1991-1993) of pre-manipulation characterization of the food webs in two lakes with very different food web ...

Diel oxygen uptake in Chaoborus punctipennis (diptera : culicidae)

Hydrobiologia, 1978
Oxygen consumption (µl/ mg dry wt. · hr−1 corrected to STP) in Chaoborus punctipennis was measured in a Gilson differential respirometer at two-hour intervals during 24-hour periods. Animals were held at controlled conditions similar to those at the time of collection.

Embryology of Chaoborus-induced spines in Daphnia pulex

Hydrobiologia, 1992
Daphnia pulex (Crustacea: Cladocera) embryos were found to be sensitive to a chemical cue (kairomone) in an extract of the predator Chaoborus americanus (Insecta:Diptera). Sensitivity of embryos to the kairomone remains throughout embryonic development.

Prey Vulnerability and Size Selection by Chaoborus Larvae

Ecology, 1981
The planktonic larva of Chaoborus trivittatus (Diptera: Chaoboridae) feeds in an opportunistic manner on all sizes of its major prey, Daphnia pulicaria. Nevertheless, medium—sized prey constitute a greater portion of the diet than would be expected on the basis of their relative abundance in the environment alone. The differential vulnerability of food

Geographic Variation in an Australian Species of Chaoborus (Diptera: Culicidae)

Australian Journal of Zoology, 1983
Populations of an unnamed species of Chaoborus vary geographically in south-eastern Australia, along what appears to be a north-south cline. At least five characters are involved: in the adult, wing length and the colour of the style of the male coxite; in the larva, overall size, a complex character that includes relative breadth of the head, and ...
