“…The similar-sized species D. ambigua and M. micrura showed different longevities, with a shorter lifespan for M. micrura (y12 days). This result is in accordance with Murugan (1975) and Dı´az-Castro and Hardy (1998), but is double that found in other studies (Jayatunga, 1986;Sipau´ba-Tavares and Bachion, 2002;Sarma et al, 2005). Because of the greater longevity found in our experiments than in other studies (Rocha and Matsumura-Tundisi, 1990;Bunioto and Arcifa, 2007), D. ambigua produced almost four times more neonates per female.…”

-The effects of temperature on the life table, and of seston quality on the individual growth and reproduction of cladocerans from a tropical lake were tested in the laboratory. Life-table experiments were carried out at 17 xC, 23 xC, and 27 xC. Growth bioassays tested the influence of natural seston fractions, separated by net filtration, on cladocerans. The treatments were: (1) total seston plus Scenedesmus spinosus (1 mg C.L x1 ), (2) seston j 36 mm, and (3) seston > 36 mm. Phytoplankton composition, density, and biomass were evaluated during growth experiments, together with sestonic carbon, nitrogen, and phosphorus concentrations. The intrinsic rates of natural increase were higher for Moina micrura and Daphnia ambigua at 27 xC compared to 17 xC. The age at first reproduction of both species was delayed at 17 xC. Growth rates and fecundity of M. micrura were higher in the seston fraction j 36 mm than in the fraction > 36 mm. Higher growth rates and fecundity of Moina minuta were observed in the seston enriched with the green alga in comparison to the seston j 36 mm and > 36 mm. Bosmina longirostris was unable to reproduce at 17 xC and to grow in the seston > 36 mm in one experiment. High densities and/or biomass of large colonial and filamentous algae present in the larger seston fraction could have contributed to reduce growth and reproduction. Episodes of food-quantity limitation may occur, but there was no evidence of mineral limitation, although seston C : P and C : N ratios were always above the limiting values assumed for temperate water bodies. The C : P and C : N ratios are highly influenced by carbon that originates primarily from resuspended detritus from the lake.

“…Although D. birgei's r (0.18) was lower than that obtained by Sipaúba-Tavares and Bachion (2002) for the same species in a 2 L culture medium, maximum density (2,813 individuals.L -1 ) was higher than that obtained by Prieto et al (2006) ) in culture medium may have affected the density and the performance of A. gracilis and D. birgei in the cultivated medium. As a rule, ammonia accumulation usually inhibits biomass growth and in fact prevents appropriate pulse-feeding patterns (Soletto et al, 2005).…”

Large-scale lab culture of Ankistrodesmus gracilis and Diaphanososma birgei were evaluated by studying the biology and biochemical composition of the species and production costs. Ankistrodesmus gracilis presented exponential growth until the 6 th day, with approximately 144 x 10 4 cells.mL , aumentando novamente a partir do décimo segundo dia. A alga clorofícea A. gracilis e o zooplâncton D. birgei possuem aproximadamente 50 e 70% de proteína (PS), respectivamente, com teor de carboidrato acima de 5%. A eletricidade e mão de obra foram os itens mais dispendiosos e, de acordo com os dados obtidos, a temperatura, nutrientes, disponibilidade de luz e manejo do cultivo, foram fatores determinantes sobre a produtividade. Os resultados indicam que o meio NPK (20-5-20) pode ser utilizado diretamente como uma alternativa de cultivo em larga escala, considerando o baixo custo de produção, promovendo adequado crescimento e valor nutricional para A. gracilis e D. birgei.

In view of its fundamental and pervasive influences and impacts on organism physiology and ecology, body size is recognized as a key component of evolutionary fitness and serves as the cornerstone of a seminal contribution in freshwater zooplankton ecology-the Size Efficiency Hypothesis (SEH) of Brooks & Dodson (Science 150:28-35, 1965). While the roles and implications of body size in predation and competition-central tenets of the SEH-have been widely considered and reviewed, no broader integrated synthesis exists of the collective array of body size determinants and their implications in the ecology in crustacean zooplankton-a numerically and functionally dominant group of aquatic organisms. Focusing on planktonic Cladocera and Copepoda in inland waters, in particular, we provide a wide-ranging overview of the direct and/or indirect effects of environmental conditions, consumable resources and biotic interactions that independently and/or collectively influence the phenotypic expression of body size (particularly as length), both within and between species. Some indirect ultimate evolutionary consequences of body size are considered, and we identify some controversies and unresolved issues related to this biologically crucial trait. While by no means exhaustive, our overview reveals a complex nexus of extrinsic proximate abiotic and biotic factors and interactions that influence body size, the phenotypic expression of which in natural systems commonly reflects contrasting outcomes related to conflicting direct and/or indirect selective pressures. In general, however, body size (both interand intra specifically) declines with rising temperature and increases with rising food supply (depending on its quality), although both temperature and food supply exert contrary influences on particular taxa (or life history stages) under certain environmental circumstances. Predation undoubtedly has an overriding influence on body size selection. Depending on its mechanistic basis (visual, tactile or both in tandem), it selectively favours either small or large body size, both within (adults vs. juveniles) and between prey species, which are accordingly often 'size-trapped' between contrasting selective pressures, with consequent indirect effects. The bioenergetics of fundamental physiological processes undoubtedly set constraints on body size and serve as the primary determinant. However, within such
