“…Goulden (1968) reported a maximum size of 1.5 mm for parthenogenetic females, but some specimens of the Pampean lakes, as well as some from Corrientes (Paggi 1997) and Rio de Janeiro, exceed this size (Elmoor-Loureiro et al 2010) (1.19 mm and 1.08 mm, respectively). The sizes of the specimens from La Pampa were similar to those recorded by Hanazato & Yasuno (1984) and Benider et al (2002), although in the latter two cases they were specimens bred in the laboratory, under controlled feeding and temperatures between 20 and 25 °C.…”

“…Okolodkov et al (2007) included this species within a list of 94 potential invaders of inland waters, coastal and littoral lakes in Mexico, suggesting more than one possible mechanism for their introduction, among which they considered aquaculture activities. Badii & Landeros (2006 noted that a successful colonizing species presented type r strategies characterized by a short generation time and high fertility, which are characteristics that have also been observed in M. macrocopa (Benider et al 2002). Allendorf & Lundquist (2003) mentioned that the success of invasive species could also be due to the absence of enemies, which would enable them to grow and reproduce without the regulatory effect of a predator on the population.…”

“…Although it has been shown that M. macrocopa can survive up to 35 °C under controlled laboratory conditions (Benider et al 2002), this species has been recorded in natural conditions in temperatures ranging between 8 and 26 °C (Benider et al 2002). The temperature range in the lakes of the province of La Pampa is similar, although the highest temperature at which M. macrocopa was recorded was slightly higher (almost 27 °C).…”

“…Han sido descriptas dos subespecies, M. macrocopa macrocopa (Straus, 1820), cuya distribución original estaba restringida al Viejo Mundo y M. macrocopa americana Goulden, 1968, registrada en América del Norte. En 1994 fue hallada en Bolivia y en 1997 en el noreste de Argentina.…”

Moina macrocopa is common in eutrophic water bodies. Two subspecies have been described: M. macrocopa macrocopa (Straus, 1820), whose original distribution was restricted to the Old World, and M. macrocopa americanaGoulden, 1968, recorded only in North America. In 1994, the species was found in Bolivia, and in 1997 it was found in the northeast of Argentina. As the specimens belonged to M. macrocopa macrocopa in both cases, the authors suggested that it may have been introduced from the Old World by anthropogenic means. The aim of this study was to assess the distribution of M. macrocopa in La Pampa (Argentina), and provide information on its population characteristics under natural conditions. The species was recorded in six out of more than 100 water bodies surveyed; the specimens belong to M. macrocopa macrocopa. Although this species is not considered halophilic, the water bodies where it was found present high salinity (5.7 to 21.8 g.L–1). All are shallow, temporary and hypertrophic due to the agricultural activities carried out in their basins. Densities were between 1 and 312.6 ind.L–1. Size varied between 0.6 and 1.8 mm and some specimens were larger than those of other places. The parthenogenetic fraction predominated and the number of eggs ranged between 2 and 23. No correlations were found between density, size, or number of eggs and the environmental parameters studied. The presence of M. macrocopa in Pampean lakes could be due to the introduction of fish from hatcheries in the province of Buenos Aires, where it is used as food. Considering that the invasive character ofM. macrocopa has been recognized and that this study found that it is tolerant to a wide range of environmental conditions, attention should be paid to a possible displacement of its native congeneric species, typical of saline and temporary water bodies in central Argentina.

“…Further, this population decline is followed by an increase in the population growth of D. spinulosum and C. cornuta in the dam. This strategy of rapid growth, or "explosive growth" according to Romanovsky (1985), was reported by Benider et al (2002), Ferrão-Filho et al (2003), and Duncan (1989); their studies suggest that, after a period of population growth, these species invest almost all their energy on sexual reproduction, in order to guarantee an adequate stock of resting eggs in the sediment, with the consequential effect of continued species existence (Lynch, 1980;Rojas et al, 2001). This pattern is common at several aquatic ecosystems of semi-arid regions in Paraiba state, where, depending on environmental stability, M. minuta may produce different proportions (high or low) of ephippial females, soon after their density peaks (Crispim et al, 2003).…”

The ontogenetic diet shifts and age specific ability of the two cladoceran species Moina macrocopa and Ceriodaphnia cornuta to derive energy from ciliated protists have been investigated in laboratory. The postembryonic developmental rates and life table demography (longevity, age and size at first reproduction, fecundity and intrinsic rate of natural increase) of the cladocerans have been elucidated on algae (Chlorella vulgaris) and the ciliated protists (Tetrahymena pyriformis, Colpoda (c.f.) steini) as food. For either of the cladoceran, the somatic growth rate and average body size at first reproduction were higher with algal diet. During initial stages of development (0-5 days), either cladoceran realized higher rate of somatic growth on algal diet, subsequently ciliated protists supported significantly higher growth rate than the alga. Algal and ciliate diets did not differ in maximum body size (C. cornuta: 539-554 μm; M. macrocopa: 1274.8-1309 μm) reached by either of the cladocerans. The maximum body sizes were larger than size at first reproduction with either of the ciliated protists, however, with algal diet the maximum body sizes did not differ from the size at first reproduction in each case. In case of C. cornuta the generation time (20.5 ± 0.3 days on ciliate; 15.6 ± 0.17 days on algal diet), reproductive rates (net reproductive rate: 20.05 ± 3.2 on ciliate; 15.5 ± 1.2 on algal diet), and average life expectancy at hatching (27 ± 0.8 days on ciliate; 22.7 ± 0.71 days on alga) were higher, whereas the size at first reproduction (482 μm on ciliate; 521 μm on alga) was smaller with the ciliate than with an algal diet. The algal and the ciliate diets did not differ in survival (life expectancy at hatching: 9.2 ± 0.7 days) and fecundity (NRR: 23.6 ± 2.4) for M. macrocopa. The two ciliates used in the experiment did not differ in their performance as food source for either cladoceran species. Our results suggest that both the cladoceran species are able to utilize smaller ciliate (e.g., T. pyriformis, C. (c.f.) steini) as food; however with differential ability to derive energy from the ciliate diet and this ability is size and age structured in both cases.
