Avian brood parasitism is a fascinating reproductive strategy wherein parasitic birds, such as the common cuckoo, lay their eggs in the nests of other avian species. This deceptive tactic forces ...

Molecular biologists have decoded the genome of the Pristionchus pacificus nematode, thereby gaining insight into the evolution of parasitism. They have shown that the genome of the nematode consists ...

Many animal species add their eggs to the brood of other species to benefit from the latter’s brood care. This is called brood parasitism. Researchers recently studied brood parasitism in two ...
