DOI: 10.1002/ecy.4014
Abstract: Bet-hedging is an ecological risk-aversion strategy where a population does not commit all its effort towards a single reproductive event or specific environmental condition, and instead spreads the risk to include multiple reproductive events or… read more here.

Bet-hedging in bacteriocin producing Escherichia coli populations: the single cell perspective
Sign Up to like & getrecommendations! Published in 2017 at "Scientific Reports"
DOI: 10.1038/srep42068
Abstract: Production of public goods in biological systems is often a collaborative effort that may be detrimental to the producers. It is therefore sustainable only if a small fraction of the population shoulders the cost while… read more here.

DOI: 10.1093/aob/mcx158
Abstract: Background and Aims Regeneration dynamics in many arid zone grass species are regulated by innate seed dormancy mechanisms and environmental cues (temperature, moisture and fire) that result in infrequent germination following rainfall. This study investigated… read more here.

DOI: 10.1111/oik.04186
Abstract: The adaptive response of organisms to unpredictable environments is increasingly recognized as a central topic in fundamental and applied evolutionary ecology. Selection due to environmental unpredictability can act on multiple traits of an organism's life… read more here.

Obligate annual and successive facultative diapause establish a bet‐hedging strategy of Rhagoletis cerasi (Diptera: Tephritidae) in seasonally unpredictable environments
Sign Up to like & getrecommendations! Published in 2017 at "Physiological Entomology"
DOI: 10.1111/phen.12206
Abstract: To cope with temporal and spatial heterogeneity of habitats, herbivorous insects in the temperate zone usually enter diapause that facilitates synchronization of their life cycle with specific stages of host plants, such as fruit ripening.… read more here.

Preparation for Denitrification and Phenotypic Diversification at the Cusp of Anoxia: a Purpose for N2O Reductase Vis-à-Vis Multiple Roles of O2
Sign Up to like & getrecommendations! Published in 2022 at "Applied and Environmental Microbiology"
DOI: 10.1128/aem.01053-22
Abstract: Denitrifying bacteria have evolved elaborate regulatory networks securing their respiratory metabolism in environments with fluctuating oxygen concentrations. Here, we provide new insight regarding their bet-hedging in response to hypoxia, which minimizes their N2O emissions because… read more here.

DOI: 10.3389/fnbeh.2021.659331
Abstract: When organisms’ environmental conditions vary unpredictably in time, it can be advantageous for individuals to hedge their phenotypic bets. It has been shown that a bet-hedging strategy possibly underlies the high inter-individual diversity of phototactic… read more here.

Quantifying the Selective, Stochastic, and Complementary Drivers of Institutional Evolution in Online Communities

DOI: 10.3390/e24091185
Abstract: Institutions and cultures usually evolve in response to environmental incentives. However, sometimes institutional change occurs due to stochastic drivers beyond current fitness, including drift, path dependency, blind imitation, and complementary cooperation in fluctuating environments. Disentangling… read more here.
