Predation effects of the calanoid copepod
This study investigated feeding rates and selective feeding of the common copepod Acartia tonsa on mixtures of the heterotrophic dinoflagellate Protoperidinium cf. divergens and the cooccurring red-tide dinoflagellate Gonyaulax polyedra and predation effects of A. tonsa on the population growth of P cf. divergens during simulated red-tide and non-red-tide periods. Ingestion and clearance rates ...
متن کاملPredation by the heterotrophic dinoflagellate Protoperidiniurn cf. divergens on copepod eggs and early naupliar stages
The heterotrophic dinoflagellate Protopemdinium cf. divergens, known as prey for adult copepods, itself feeds on copepod eggs and early naupliar stages. One to several P. cf. divergens can attack an egg or nauplius larger than themselves. The time for an egg to be digested was proportional to the number of P. cf. divergens attacking it. Ingestion rates of P, cf. djvergens on Acartia tonsa eggs ...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
