Length-weight relationships and biomass of the main microcrustacean species of two large tropical reservoirs in Brazil.
Length-weight equations were determined for the main microcrustacean species of Três Marias and Furnas reservoirs (state of Minas Gerais, Brazil), and evaluated the fluctuations of their biomass. We examined the following species: Thermocyclops minutus, Bosminopsis deitersi, Bosmina hagmanni, Ceriodaphnia cornuta, and Moina minuta (Três Marias Reservoir), and Notodiaptomus henseni, Daphnia ambi...
متن کاملPopulation growth and development of two species of Cladocera, Moina micrura and Diaphanosoma birgei, in laboratory.
The objective of the present work was to investigate the influence of four diets on population growth, development, total length, dry weight, and nutritional value of two zooplanktonic species, Moina micrura and Diaphanosoma birgei. The four dietary treatments were: algae alone (A); algae + vitamins (AV); algae + ration (AR); and algae + ration + vitamins (ARV). Growth rate peak for both specie...
متن کاملEffects of a vertebrate predator (Poecillia reticulata) presence on Ceriodaphnia cornuta (Cladocera: Crustacea) in laboratory conditions
Aim: To detect the induction of morphological and populational alterations on Ceriodaphnia cornuta concerning cyclomorphosis and population dynamic parameters as densities, fecundity rates, juveniles percentage, males presence and ephippia presence in the presence of predators; Methods: Two experiments were performed: Experiments with fishes fed on Ceriodaphnia cornuta – Experiment 1 – and “Fis...
متن کاملEffect of Different N Fertilizer Combinations and Irrigation Regimes on Concentration, Uptake and Efficiency of Major Nutrients in Plantago ovata
In order to evaluate the response of major nutrients concentration, uptake and their efficiencies of isabgol (Plantago ovata) to N fertilizer combinations and irrigation regimes, a field experiment was conducted at the agricultural research farm of Shahrekord University, 2009. The experiment was arranged as split-plot, in randomized complete block design with three replications. The irrigation ...
متن کاملThe ancient Balkan lakes harbor a new endemic species of Diaphanosoma Fischer, 1850 (Crustacea: Branchiopoda: Cladocera).
Diaphanosoma macedonicum sp. nov. is described from material collected from the ancient Lakes Dojran and Prespa, located in the central part of the Balkan Peninsula. It can be regarded as a member of the "D. mongolianum" species group. It is characterized by specific, but not readily visible features, such as the absence of a thorn near the posterior valve margins, as well as setules between se...
