Cost of reproduction in selected species of zooplankton (rotifers and cladocerans)
, 2002 Reproduction is an energetically costly biological process. Among the freshwater zooplankton, rotifers and cladocerans reproduce parthenogenetically and the cost of reproduction can be estimated using the life table data from demographic studies. Reduced

Effects of climate on size structure and functioning of aquatic food webs [PDF]
, 2010 In aquatic food webs, the role of body size is notoriously strong. It is also well known that temperature has an effect on body size. For instance, Bergmann’s rule states that body size increases from warm to cold climates.

Ecological IndicatorsAquatic biodiversity is essential for maintaining lake ecosystem health, yet large-scale studies linking zooplankton communities, particularly cladocerans to environmental gradients remain limited in the world's most populous heartland (Asia).

Cladocerans and copepodans biodiversity in Naděje fishponds systém.
, 2009 Biodiversity of planktonic crustaceans, cladocerans and copepodans in southbohemian Naděje fishponds system were studied. Both fishpond and non-fishpond (pools, canals, sand-pits, river) localities were observed.

, 2007 Cyanobacteria blooms (especially Microcystis spp.) are thought to alter dominance of large-sized daphnids into small-sized metazoan zooplankton. However, several field investigations show different phenomena.

ON THE OCCURRENCE OF CLADOCERAN REMAINS IN LAKE SEDIMENTS [PDF]
Proceedings of the National Academy of Sciences, 1960 openaire +2 more sources
, 1997 The role of large laboratory grown food competitors of the genus Daphnia as well as the predation impact of Chaoborus on the cladoceran community of an eutrophic lake was assessed in five in situ enclosure experiments.

Is competition an interaction as relevant as predation for tropical planktonic cladocerans?
, 2018 Aim To test the relevance of competition and predation for the two most abundant and frequent cladoceran populations, the medium-sized Ceriodaphnia richardi Sars, 1901 and the large-sized Daphnia gessneri Herbst, 1967, in a tropical shallow lake ...

Hormonal induction of undescribed males resolves cryptic species of cladocerans [PDF]
, 2006 Cyclic parthenogens have a mixed breeding system with both meiotic and ameiotic eggs. Although investment in sexual stages is often synchronized with seasonal cycles, the degree of investment is a quantitative trait associated with habitat instability ...

, 2017 The annual cycle of marine cladocerans was studied over six years from 1994 to 1999 within the frame of the monitoring Project ECOMALAGA at a nine stations in the NW of the Alboran Sea, with the aim of assessing seasonal patterns and interannual trends ...
