Parasite survives predation on its host

Article Abstract:

The parasitic gordian worm Paragordius tricuspidatus is able to escape from its insect host after ingestion by a fish or frog, and also from the digestive tract of the predator and this remarkable tactic enables the worm to continue its life cycle. Few parasites have their own predators, although they are victims of those of their hosts, and predation upon a host might shape parasite life history in two ways, first increased predation and second predation might affect parasite life history if incorporated into life cycle.

Arboreal ants build traps to capture prey

Article Abstract:

A study on the ambush tactics adopted by arboreal ants like ant Allomerus decemarticulatus to capture flying and jumping prey is demonstrated. The ant Allomerus decemarticulatus uses hair from the host plant's stem, which it cuts and binds together with a purpose grown fungal mycelium, to build a spongy galleried platform for trapping much larger insects.

Stage-structured cycles promote genetic diversity in a predator-prey system of Daphnia and algae

Article Abstract:

The first experimental test of whether alternative types of cycles affect natural selection in predator-prey systems is provided. Externally forced cycles show rapid competitive exclusion.
