Polyandry works as bet-hedging in the field cricket Gryllus bimaculatus, even after eliminating females in poor condition that cannot accept remating
Any kind of unpredictability affects female reproduction. In fluctuating environments, the fittest genotype can change between generations, and...

Ecological, (epi)genetic and physiological aspects of bet-hedging in angiosperms
Key messageBet-hedging is a complex evolutionary strategy involving morphological, eco-physiological, (epi)genetic and population dynamics aspects....

An empirical test of bet-hedging polyandry hypothesis in the field cricket Gryllus bimaculatus
Theory shows that polyandry (mating with multiple males within a reproductive season) works as bet-hedging to increase the geometric mean fitness...

Cohort splitting from plastic bet-hedging: insights from empirical and theoretical investigations in a wolf spider
Bet-hedging strategies help organisms to decrease variance in their fitness in unpredictably changing environments, by which way lineage fitness can...

The allocation between egg size and clutch size depends on local nest survival rate in a mean of bet-hedging in a shorebird
BackgroundThe allocation of resources between offspring size and number is a central question of life-history theory. Although several studies have...

Semelparous Reproductive Strategy in New World Marsupials
Semelparity means “reproducing once,” that is, individuals of a particular species have a single opportunity to leave descendants. This strategy was...

Trade-offs between diaspore dispersal and dormancy within a spike of the invasive annual grass Aegilops tauschii
Main conclusionDifferences in dispersal and dormancy of heteromorphic diaspores of Aegilos tauschii may increase its flexibility to invade/occupy...

Single-cell massively-parallel multiplexed microbial sequencing (M3-seq) identifies rare bacterial populations and profiles phage infection
Bacterial populations are highly adaptive. They can respond to stress and survive in shifting environments. How the behaviours of individual bacteria...

Nesting attempts and annual fecundity in a population of the yellow-chinned spinetail (Certhiaxis cinnamomeus), with a review on Neotropical passerines
Knowledge on nesting attempts and annual fecundity are essential to understand avian population dynamics, viability, and life history adaptations,...

Semelparous Reproductive Strategy in New World Marsupials
Semelparity means “reproducing once,” that is, individuals of a particular species have a single opportunity to leave descendants. This strategy was...

RNA recording in single bacterial cells using reprogrammed tracrRNAs
Capturing an individual cell’s transcriptional history is a challenge exacerbated by the functional heterogeneity of cellular communities. Here, we...

Can colony resizing represent a strategy for octocorals to face climate warming? The case of the precious red coral Corallium rubrum
Modular colonial benthic organisms exhibit high phenotypic plasticity, which is considered an effective strategy when faced with fluctuations in...

Bet hedging in stochastic habitats: an approach through large branchiopods in a temporary wetland
Organisms evolve to maintain fitness across generations, while short-term fitness in stochastic habitats such as temporary wetlands may be highly...

Inter- and intra-species heterogeneity in germination of Aspergillus conidia
Aspergilli are among the most abundant fungi worldwide. They degrade organic material and can be pathogens of plants and animals. Aspergilli spread...

A review of iteroparity in anadromous salmonids: biology, threats and implications
Iteroparity occurs when organisms reproduce more than once, and is seen as a bet-hedging reproductive strategy. Despite a wealth of research on...

Is There More to Within-plant Variation in Seed Size than Developmental Noise?
Within-plant variation in seed size may merely reflect developmental instability, or it may be adaptive in facilitating diversifying bet-hedging,...

Staying in touch: how highly specialised moth pollinators track host plant phenology in unpredictable climates
BackgroundFor specialised pollinators, the synchrony of plant and pollinator life history is critical to the persistence of pollinator populations....

Maternally derived variation in the early termination of dormancy in Daphnia pulex
The timing and duration of dormancy can be influenced by many environmental cues, such as changes in light and temperature. This study examined the...

A bacterial signaling system regulates noise to enable bet hedging
Phenotypic diversity helps populations persist in changing and often unpredictable environments. One diversity-generating strategy is for individuals...

Diminishing returns drive altruists to help extended family
Altruism between close relatives can be easily explained. However, paradoxes arise when organisms divert altruism towards more distantly related...
