Predation 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 کاملEffect of Egg Weight on Egg Traits and Hatching Performance of Turkey (Meleagris gallopavo) Eggs
The study was conducted to determine the effects of turkey (Meleagris gallopavo)egg weight on certain egg traits and hatching performance. A total of 178 turkey eggs comprising of three different egg weight groups below 60 g (G I), 61 to 69 g (G II) and above 70 g (G III) were used for this study. Average egg weight (g), egg length (cm), egg breadth (cm) and egg volume (cm3) values increased wi...
متن کاملPredation 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 کاملTactical deception reduces predation on birds' eggs.
I n the months leading up to the 1973 Yom Kippur War, the Egyptian military staged 40 maneuvers on or near the Israeli border. Over time, the Israelis learned that Egyptian activity near the border was not necessarily a threat to respond to, and they ultimately let their guard down, only to be surprised one day when the tanks and troops crossed the border as part of a coordinated invasion (1, 2...
