Journal of Limnology, 2008 Daphnia and Bosmina fragments were identified and measured in the surface sediments of 42 lakes in the Muskoka-Haliburton region of Ontario, Canada, in an attempt to identify environmental factors that may influence cladoceran body size.

Energetics of Vertical Migration in Chaoborus Trivittatus Larvae [PDF]
Ecology, 1976 One of the recent theories for the adaptive value of vertical migration states that migrants gain an energetic advantage over nonmigrants because by alternating between areas of high and low temperatures they are able to partition energy into growth more efficiently than nonmigrants.

Journal of Limnology, 2002 The response of Daphnia populations to invertebrate predators involves morphological changes and can lead to a trade-off between growth- and reproduction-related traits.

Stable isotope patterns in lake food webs reflect productivity gradients
Ecosphere, 2020 Stable isotopes 13C and 15N are often used in lake ecosystems to assess energy sources and trophic positions, respectively. However, δ13C and δ15N are also influenced by internal biogeochemical processes in epilimnetic and hypolimnetic habitats in lakes,

The quality of water of the Mantovo reservoir, Republic of Macedonia [PDF]
Archives of Biological Sciences, 2009 The aim of the paper is to evaluate the quality of water of the Mantovo Reservoir (Southeast Macedonia)based on physico-chemical parameters and the macrozoobenthos. Monthly sampling was performed during 2003 and 2004.

Freshwater Biology, Volume 71, Issue 7, July 2026.ABSTRACT Fishless lakes, which may harbour higher biodiversity than lakes with fish, are becoming increasingly rare due to fish introductions. Although the impacts of fish introduction are relatively well studied in high‐elevation fishless lakes, previous studies have mainly focused on a single invertebrate community or on a particular life stage of a ...

Acta Scientiarum: Biological Sciences, 2008 Inúmeros trabalhos têm mostrado que a larva de Chaoborus desenvolve migração vertical diária, buscando evitar a predação por peixes, e que a amplitude da migração vertical cresce com o estágio larval. Neste estudo, monitorou-se a distribuição vertical de

Some aspects of prey capture by Chaoborus larvae1 [PDF]
Limnology and Oceanography, 1975 The effects of prey size, shape, and locomotion on capture, ingestion, and handling time were investigated in second‐, third‐, and fourth‐instar larvae of Chaoborus americanus and Chaoborus trivittatus from Eunice Lake, British Columbia. Before contact, densities and swimming speeds of predators and prey determine the number of interactions and hence ...
