Invertebrate zooplankton predator composition and diversity in tropical lentic waters Copepoda which comprise the majority of limnetic predators are particularly low in species numbers in the tropics. Predatory Cladocera are confined to the North Temperate zone. . appears to be cosmopolitan. Among Rotifera, only the cosmopolitan predator . occurs in tropical waters while the other c

Progress towards characterization of a predator/prey kairomone: , and ,tor is a water-soluble chemical. We provide evidence that this kairomone originates in the intestinal tract of the predator. The active compound is an organic molecule of intermediate polarity which is heat stable and partially destroyed by acid and base digestion. It is stable to digestion by the g

Laboratory observations on the vertical distribution of a tropical pelagic flatworm (, sp.) in relatals was monitored in 25 cm high columns exposed to natural sunlight. Phototactic responses were studied under standardised experimental conditions..Satiated individuals resided nearer to the bottom than non-satiated .. Non-satiated individuals showed an irregular vertical distribution due to swimmin
