Aggregation in Aphis varians: an effective strategy for reducing predation risk

, : Aggregation in Aphis varians: an effective strategy for reducing predation risk. Ecology (Washington D C): 704: 1008-1016

The advantages or disadvantages of clumping to prey was studied for the interaction between Aphis varians and the coccinellid Hippodamia convergens on fireweed (Epilobium angustifolium) in Washington during 1986-87. Aphids tended to stay within clumps of conspecifics.

If a mutualistic relationship entails providing services at a cost, selection will favor individuals that maximize the net benefits of the interaction and minimize the costs.

Attacks on redshank flocks of different sizes and by diff...

Predator-prey interactions have a major effect on species abundance and diversity, and aggregation is a well-known anti-predator behaviour. For immobile prey, the effectiveness of aggregation depends on two conditions: (a) the inability of the pre...

Aggregation in bark beetles (Coleoptera: Scolytidae) aids in mate attraction and resource procurement when colonising well-defended plants; however, some species colonise primarily poorly defended plants, and intraspecific competition increases...

The commonly held view that exercise alone is not a useful strategy for obesity reduction is drawn from studies with limitations that confound interpretation.
