Evolution of Cooperation in the Snowdrift Game with Incomplete Information and Heterogeneous Population

Differently from previous studies of tag-based cooperation, we assume that individuals fail to recognize their own tag. Due to such incomplete information, the action taken against the opponent cannot be based on similarity, although it is still motivated by the tag displayed by the opponent. We present stability conditions for the case when individuals play unconditional cooperation, unconditional defection or conditional cooperation. We then consider the removal of one or two strategies. Results show that conditional cooperators are the most resilient agents against extinction and that the removal of unconditional cooperators may lead to the extinction of unconditional defectors.

Variantes genéticas en ANRIL y longevidad

[ES] En este trabajo se ha analizado el efecto de 4 tag-SNPs localizados en la región promotora del ARN no codificante ANRIL en la población longeva. Se cree que la desregulación de ANRIL podría estar asociada a la longevidad, considerando que esta desregulación podría ser debida a variantes genéticas en la región promotora del mismo.
