One of the most elusive scientific challenges for over 150 years has been to explain why cooperation survives despite being a seemingly inferior strategy from an evolutionary point view. Over years, various theoretical scenarios aimed at solving puzzle have proposed, eventually identifying several cooperation-promoting mechanisms: kin selection, direct reciprocity, indirect network and group selection. We report results repeated Prisoner's Dilemma experiments with anonymous onymous pairwise...
The decoy effect is a cognitive bias documented in behavioural economics by which the presence of third, (partly) inferior choice causes significant shift people's preference for other items. Here, we performed an experiment with human volunteers who played variant repeated prisoner's dilemma game standard options "cooperate" and "defect" are supplemented new, option, "reward". We show that although rarely chose its availability sparks increase overall cooperativeness improves likelihood...
Significance The evolution of cooperation has a formative role in human societies—civilized life on Earth would be impossible without cooperation. However, it is unclear why evolve the first place because Darwinian selection favors selfish individuals. After struggling with this problem for >150 y, recent scientific breakthroughs have uncovered multiple cooperation-promoting mechanisms. We build these by examining whether two widely known mechanisms—network reciprocity and costly...
Significance Collective risks trigger social dilemmas that require balancing selfish interests and common good. One important example is mitigating climate change, wherein without sufficient investments, worldwide negative consequences become increasingly likely. To study the aspects of this problem, we organized a game experiment reveals how group size, communication, behavioral type drive prosocial action. We find communicating sentiment outlook leads to more positive outcomes, even among...
What do corruption, resource overexploitation, climate inaction, vaccine hesitancy, traffic congestion, and even cancer metastasis have in common? All these socioeconomic sociobiological phenomena are known as social dilemmas because they embody one form or another a fundamental conflict between immediate self-interest long-term collective interest. A shortcut to the resolution of has thus far been reserved solely for highly stylised cases reducible dyadic games (e.g., Prisoner's Dilemma),...
Abstract The use of traits is growing in ecology and biodiversity informatics, with initiatives to collate trait data integrate it into databases. A need develop better predictive capacity for how species respond environmental change has part motivated this focus. Functional are most interest—those a defined link individual survival, development, growth reproduction. Non‐trivial challenges arise immediately deciding which functional prioritise characterise them. Here we discuss the...
We formulated a full lifecycle bioenergetic model for bluefin tuna relying on the principles of Dynamic Energy Budget theory. Traditional models in fish research deduce energy input and utilization from observed growth reproduction. In contrast, our predicts reproduction food availability temperature environment. calibrated to emulate physiological characteristics Pacific (Thunnus orientalis, hereafter PBT), species which has received considerable scientific attention due its high economic...
We study the coevolution of strategies and network interdependence in context a public goods dilemma. Specifically, players occupy nodes engage games, with twist that those who post good result terms payoff are allowed to form external links from another network. These may bring additional utilities players. Moreover, between on different networks become stronger if keep posting results, but weaken otherwise. By means Monte Carlo simulations, we show that, as long benchmark for recognition...
The progression of game theory from classical to evolutionary and spatial games provided a powerful means study cooperation, enabled better understanding general cooperation-promoting mechanisms. However, current standard models assume that at any given point players must choose either cooperation or defection, meaning regardless the structure in which they exist, cannot differentiate between their neighbours adjust behaviour accordingly. This is odds with interactions among organisms nature...
Cooperation is the backbone of modern human societies, making it a priority to understand how successful cooperation-sustaining mechanisms operate. Cyclic dominance, non-transitive set-up comprising at least three strategies wherein first strategy overrules second, which third, which, in turn, strategy, known maintain biodiversity, drive competition between bacterial strains, and preserve cooperation social dilemmas. Here, we present novel route cyclic dominance voluntary dilemmas by adding...
A complex network is a model representation of interactions within technological, social, information, and biological networks. Oftentimes, we are interested in identifying the underlying structure from limited noisy observational data, which challenging problem. Here, to address this problem, propose novel effective technique that incorporates latent structural constraints into binary compressed sensing. We show high accuracy robust effectiveness our proposed method by analyzing artificial...
Social dilemmas are situations wherein individuals choose between selfish interest and common good. One example of this is the vaccination dilemma, in which an individual who vaccinates at a cost protects not only himself but also others by helping maintain good called herd immunity. There is, however, strong incentive to forgo vaccination, thus avoiding associated cost, all while enjoying protection To analyze behavioral incentives vaccination-dilemma setting optional treatment available...
Patterns in nature are fascinating both aesthetically and scientifically. Alan Turing’s celebrated reaction–diffusion model of pattern formation from the 1950s has been extended to an astounding diversity applications: cancer medicine, via nanoparticle fabrication, computer architecture. Recently, several authors have studied underlying networks, but thus far, controlling a system network obtain particular remained elusive. We present solution this problem form analytical framework numerical...
Abstract Because of the critical role transportation in modern times, one most successful application areas statistical physics complex networks is study traffic dynamics. However, vast majority works treat as an isolated system, which inconsistent with fact that many are interrelated a nontrivial way. To mimic realistic scenario, we use framework multilayer to construct two-layered model, whereby upper layer provides higher transport speed than lower layer. Moreover, passengers guided...
