Data from: Reproductive isolation in alpine gingers: how do co-existing Roscoea (R. purpurea and R. tumjensis) conserve species integrity?

Babu Ram Paudel, Martin Burd, Mani Shrestha, Adrian G. Dyer, Qingjun Li & Qing-Jun Li
Multiple barriers may contribute to reproductive isolation between closely related species. Understanding the relative strength of these barriers can illuminate the ecological factors that currently maintain species integrity and how these factors originally promoted speciation. Two Himalayan alpine gingers, Roscoea purpurea and R. tumjensis, occur sympatrically in central Nepal and have such similar morphology that it is not clear whether or how they maintain a distinct identity. Our quantitative measurements of the components of reproductive...

Data from: Aspiration-based coevolution of link weights promotes cooperation in the spatial prisoner's dilemma game

Chen Shen, Chen Chu, Lei Shi, Matjaz Perc & Zhen Wang
In this article, we propose an aspiration-based coevolution of link weights, and we explore how this affects the evolution of cooperation in the spatial prisoner's dilemma game. In particular, an individual will increase the weight of its link to its neighbors only if the payoff received via this interaction will exceed a pre-defined aspiration. Conversely, if the received payoff is below this aspiration, the link weight with the corresponding neighbor will be decreased. Our simulation...
