Social Evolution: Sick Ants Face Death Alone
Social insects not only live altruistically, they die so: a new study reveals that moribund ants abandon their nests to die in seclusion, which reduces the risk of transmitting diseases to relatives.
متن کاملConvergent evolution of social hybridogenesis in Messor harvester ants.
Sexual reproduction generally requires no more than two partners. Here, we show convergent evolution of social hybridogenesis, a reproductive system requiring three reproductive partners in harvester ants. In this unorthodox reproductive system, two distinct genetic lineages live in sympatry and queens have to mate with males of their own lineage to produce queens along with males of the altern...
متن کاملSocial Evolution: Daily Self-Sacrifice by Worker Ants
Each evening, a few workers of a Brazilian ant doom themselves to die overnight by remaining outside the nest to seal its entrance. This striking behaviour is a novel form of worker self-sacrifice.
متن کاملThe Evolution of Invasiveness in Garden Ants
It is unclear why some species become successful invaders whilst others fail, and whether invasive success depends on pre-adaptations already present in the native range or on characters evolving de-novo after introduction. Ants are among the worst invasive pests, with Lasius neglectus and its rapid spread through Europe and Asia as the most recent example of a pest ant that may become a global...
متن کاملThe evolution of agriculture in ants
Cultivation of fungi for food by fungus-growing ants (Attini: Formicidae) originated about 50 million years ago. The subsequent evolutionary history of this agricultural symbiosis was inferred from phylogenetic and population-genetic patterns of 553 cultivars isolated from gardens of "primitive" fungus-growing ants. These patterns indicate that fungus-growing ants succeeded at domesticating mul...
