“…Maximum values were lower than the maximum densities recorded for the same species (SAINT-JEAN and BONOU, 1994) or congeneric species (TIFNOUTI and POURRIOT, 1989) in shallow, eutrophic and non-predator environments. According to SAINT-JEAN and BONOU (1994), food limitation and fish predation can explain a low population density of M. micrura in natural environments. In our pond, the effect of killifish predation on population density of M. micrura was evident (Fig.…”

“…Moina micruru KURZ ist a cosmopolitan cladoceran species, broadly distributed in tropical and subtropical lakes and ponds (GOULDEN, 1968). Some studies have indicated that in favourable environmental conditions, M. micruru populations have relative high fecundity, small eggs, short juvenile development time and low number of juvenile stages (SAINT-JEAN and BONOU, 1994), and it has been considered as an opportunistic species. However, information on demographic features of natural tropical populations in shallow waterbodies is scarce and limited to large lakes SAINT-JEAN, 1978 a, 1978 b;SAINT-JEAN, 1983) and aquaculture ponds (BONOU et al, 1991;SAINT-JEAN and BONOU, 1994).…”

A population of M. micrura KURZ from a shallow, muddy and temporary pond, located in Peninsula of Paraguani, western Venezuela, was studied from filling to drying phase. Population density, age structure, fecundity, and length of females, were determined. This population showed a low population density (< 50 ind/l), a low and density-dependent fecundity (mean eggdadults = 1.3; mean clutch size = 2.1 eggs + embryos), and low juveniles to adults ratio (0.71). No significant correlation was detected between mean clutch size and mean body length of ovigerous females. Our results suggest effects of food limitations, and fish predation on demographic parameters of this population. Still, in unfavourable conditions, some demographics features associated to opportunistic species were evident.

“…There is some possibly corresponding experience from African material of notably high rates in the temperature range of 25-30 °C. These include specific rates of light-saturated photosynthesis by phytoplankton (Talling 1965, Ganf 1975, and specific increase rates near 30 °C of a rotifer (Pourriot and Rougier 1975) and the micro-crustacean Moina micrura Saint-Jean 1983, Saint-Jean andBonou 1994) that correspond to population doubling in less than one day. However, there is also evidence from other groups in Africa (e.g., molluscs; Brown 1994) of the influence of contrary temperature compensation (Bullock 1955).…”

A short account is given of some features that are unique or extensively developed or intensely studied in tropical African water-bodies, and which are of fundamental limnological significance. They concern the origin and persistence of lakes and rivers; local evolution (endemism) and dispersal of species; cyclic lake stratification in relation to latitude and climate; salinity series and nutrient balance; plankton dynamics; aquatic food chains that are simplified and quantifiable or with major recent change; colonisation of new or transient water bodies by extensively invasive species; and the significance of temperature difference and absolute magnitude as ecological factors.

“…Length-weight regressions based on the population parameters of species from temperate regions differ from those obtained in tropical regions, primarily in relation to zooplankton body size, which tends to be smaller in tropical regions (Saint-Jean and Bonou, 1994). Blettler and Bonecker (2006) argued that the lack of studies with data on planktonic microcrustaceans is related to difficulties in determining the organisms' dry weight.…”

Length-weight regressions of the microcrustacean species from a tropical floodplain

Aim: This study presents length-weight regressions adjusted for the most representative microcrustacean species and young stages of copepods from tropical lakes, together with a comparison of these results with estimates from the literature for tropical and temperate regions; Methods: Samples were taken from six isolated lakes, in summer and winter, using a motorized pump and plankton net. The dry weight of each size class (for cladocerans) or developmental stage (for copepods) was measured using an electronic microbalance; Results: Adjusted regressions were significant. We observed a trend of under-estimating the weights of smaller species and overestimating those of larger species, when using regressions obtained from temperate regions; Conclusion: We must be cautious about using pooled regressions from the literature, preferring models of similar species, or weighing the organisms and building new models.Keywords: dry weight, cladocerans, copepods, biomass, secondary productivity.Resumo: Objetivo: Este estudo apresenta as regressões peso-comprimento elaboradas para as espécies mais representativas de microcrustáceos e formas jovens de copépodes em lagos tropicais, bem como a comparação desses resultados com as estimativas da literatura para as regiões tropical e temperada; Métodos: As amostragens foram realizadas em seis lagoas isoladas, no verão e no inverno, usando moto-bomba e rede de plâncton. O peso seco de cada classe de tamanho (para cladóceros) e estágio de desenvolvimento (copépodes) foi medido em microbalança eletrônica; Resultados: As regressões ajustadas foram significativas. Observamos uma tendência em subestimar o peso das espécies de menor porte e superestimar as espécies de maior porte, quando se utiliza regressões pesocomprimento obtidas para a região de clima temperado; Conclusão: Devemos ter cautela no uso de regressões peso-comprimento existentes na literatura, preferindo modelos para as mesmas espécies, ou pesar os organismos e construir os próprios modelos.Palavras-chave: peso seco, cladóceros, copépodes, biomassa, produtividade secundária.
