Feeding rates and prey : predator size ratios of the nauplii and adult females of the marine cyclopoid copepod Oithona davisae
We studied the feeding behavior of the nauplii and adult females of the marine cyclopoid copepod Oithona davisae in the laboratory. Functional response experiments showed that O. davisae can feed on a broad size range of prey but that high clearance rates only occur in a narrow prey size range. Neither the nauplii nor the females were able to feed on Nannochloropsis oculata (2.5 mm), but . 4 mm...
متن کاملPredicting single and mixture toxicity of petrogenic polycyclic aromatic hydrocarbons to the copepod Oithona davisae.
In the present study, the acute toxicity of 10 polycyclic aromatic hydrocarbons (PAHs) associated with the Prestige fuel oil spill (Spain, 2002) were evaluated, either as single substances or in mixtures, in adults of the copepod Oithona davisae. All but dimethylphenanthrene had negative effects on O. davisae survival at concentrations below their water solubility, with 48-h median lethal conce...
متن کاملLife-history responses to changing temperature and salinity of the Baltic Sea copepod Eurytemora affinis
To understand the effects of predicted warming and changing salinity of marine ecosystems, it is important to have a good knowledge of species vulnerability and their capacity to adapt to environmental changes. In spring and autumn of 2014, we conducted common garden experiments to investigate how different populations of the copepod Eurytemora affinis from the Baltic Sea respond to varying tem...
متن کاملFeeding by the cyclopoid copepod Oithona similis on the microplankton assemblage in the Oyashio region during spring
Onboard incubation experiments were conducted to examine the feeding rates and selectivity of the cyclopoid copepod Oithona similis on natural assemblages of microplankton during the spring bloom in the Oyashio region. O. similis cleared ciliates at higher rates (2.8–11.9 mL copepod 1 d ) than dinoflagellates (1.4 mL copepod 1 d ), with no detectable ingestion of diatoms. Clearance increased wi...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
