Effect of diet and temperature on the culture of Alona guttata(Sars, 1862) (Cladocera: Chydoridae) under laboratory conditions

Abstract

Effect of diet and temperature on the culture of Alona guttata (Sars, 1862) (Cladocera: Chydoridae) under laboratory conditions Efecto de la dieta y temperatura en el cultivo de Alona guttata (Sars, 1862) (Cladocera: Chydoridae) en condiciones de laboratorio

Effect of the Non-Steroidal Anti-Inflammatory Drug Ibuprofen on the Chydorid <i>Alona guttata</i> (Chydoridae: Aloninae) and the Rotifer <i>Lecane papuana</i> (Monogononta: Lecanidae) Fed on Different Algal Densities

“…In our study, artificial substrate was not included as it could adsorb the IBP and contribute (or not) to toxicity, which is not included in our aim to evaluate the effect of algal density and IBP concentration. Furthermore, subchronic toxicity tests with and without substrate addition showed no evidence of altering survival or fertility [27].…”

“…Duration of the test (exposure) differed between the two zooplankter species, which was based on their life cycle, with average lifespan of seven days for L. papuana [48], and 60 d for A. guttata [27]. Conventional toxicity tests protocols with rotifers suggest 24 h for acute tests and up to 5 d when assessing alterations on the population increase [16]; for cladocerans the standard protocols include 48-h period for acute toxicity tests and up to 21 d for Daphnia magna in chronic tests [49].…”
