Cladocerans (Branchiopoda) of a tropical estuary in Brazil [PDF]
Brazilian Journal of Biology, 2005 The study was conducted in the Capibaribe river estuary in Recife (Brazil) to assess the role played by cladocerans in a eutrophic environment. Samplings were carried out monthly at 4 fixed stations along the estuary from July 1987 to June 1988 ...

Assessment of RNA extraction protocols from cladocerans [PDF]
PLOS ONE, 2022 The usage of cladocerans as non-model organisms in ecotoxicological and risk assessment studies has intensified in recent years due to their ecological importance in aquatic ecosystems. The molecular assessment such as gene expression analysis has been introduced in ecotoxicological and risk assessment to link the expression of specific genes to a ...

Seasonal changes in the distribution and abundance of marine cladocerans of the Northwest Alboran Sea (Western Mediterranean), Spain [PDF]
Brazilian Archives of Biology and Technology, 2011 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 ...

Effects of predation by Hydra (Cnidaria) on cladocerans (Crustacea: Cladocera)
Journal of Limnology, 2016 Planktonic cladocerans have evolved different strategies to avoid predation from vertebrates; these include changes in morphology, behavior, physiology, and/or life-history traits.

An overview of the contribution of studies with cladocerans to environmental stress research
Acta Limnologica Brasiliensia, 2015 Cladocerans are microcrustaceans component of the zooplankton in a wide array of aquatic ecosystems. These organisms, in particular the genus Daphnia, have been widely used model organisms in studies ranging from biomedical sciences to ecology.

PHENOTYPES AND GENOTYPES IN CLADOCERAN POPULATIONS [PDF]
Evolution, 1978 Recently Kerfoot (1975) discussed the divergence of adjacent populations of Bosmina longirostris in response to two different kinds of predators in Union Bay, Seattle, Washington. Sampling Union Bay during the summer of 1972, he noted that animals taken along a transect from littoral to pelagic waters differed from each other with respect to egg and ...

Cladoceran juvenile growth1 [PDF]
Limnology and Oceanography, 1987 We examined juvenile growth of five species of Daphniidae raised at several food levels. For each species, an exponential model with a species‐specific exponent accurately described the weight gain of preadult instars. This finding indicates that weight‐specific net production within a species is constant throughout juvenile development; early and late

Marine Ecology, EarlyView., 2023 Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...

Seasonal abundance of small cladocerans in Lake Mangakaware, Waikato, New Zealand [PDF]
, 1999 The seasonal changes in the dynamics and life histories of the Cladocera in Lake Mangakaware, North Island, New Zealand, were studied over 19 months by sampling at weekly or 2-weekly intervals.

THE RATE OF KILLING OF CLADOCERANS AT HIGHER TEMPERATURES [PDF]
Journal of General Physiology, 1927 In spite of obvious possible sources of disturbance, the "velocity of killing" of organisms at supranormal temperatures, properly determined, tends to adhere to the Arrhenius equation for relation to temperature. Over certain ranges of temperature the relationship between log velocity of killing and 1/T° abs. is linear.
