- Understanding Evolutionary Impacts of Seasonality: An Introduction to . . .
Fluctuating selection pressures on survival and fecundity between summer and winter provide a complex selective landscape, which can be met by a combination of three outcomes of adaptive evolution: genetic polymorphism, phenotypic plasticity, and bet-hedging
- Polyphenism - Wikipedia
Some polyphenisms are seasonal, as in some butterflies which have different patterns during the year, and some Arctic animals like the snowshoe hare and Arctic fox, which are white in winter
- Ecological and evolutionary consequences of changing seasonality
Climate change is rapidly altering seasonal regimes in terrestrial, freshwater, and marine realms, disrupting the natural rhythm of ecological processes Seasonality is so fundamental to ecosystems that these shifts threaten the maintenance of biodiversity and its contributions to society
- Seasonal Polyphenism | Springer Nature Link
Much of the effort of contemporary population biology—both theoretical and experimental—is directed toward elucidating the relationship between environmental heterogeneity and genetic variability Specifically, are high levels of heterozygosity adaptive in “stable” or “unstable” environments?
- Seasonally fluctuating selection can maintain polymorphism at many loci . . .
polymorphism at many loci is possible if currently favored alleles are sufficiently dominant This general mechanism, which we call “segregation lift,” requires seasonal changes in dominance, a phenomenon that may arise naturally in situations with
- Seasonal changes in photoperiod and temperature lead to changes in . . .
Seasonal plasticity in insects is often triggered by temperature and photoperiod changes When climatic conditions become sub-optimal, insects might undergo reproductive diapause, a form of
- Genetic basis of a seasonal life-history polyphenism - bioRxiv
Abstract Seasonal polyphenisms are common across the animal and plant kingdom yet we understand the explicit interactions between genetics and environment for only a few taxa Are the genomic regions and their variants associated with the trait the same or different across environments? Is the response to selection
- (PDF) Seasonal Polyphenism - ResearchGate
Seasonal polyphenism, the development of distinct phenotypes in different seasons, is one of the important adaptive responses to seasonal changes required by multivoltine (many generations
- Predictability of temporal variation in climate and the evolution of . . .
Here, we quantify predictability in the timing of precipitation and temperature change to examine how this is associated with seasonal polyphenism in tropical Mycalesina butterflies
- Seasonally fluctuating selection can maintain polymorphism at many loci . . .
Many organisms experience some seasonality in their habitats, and, if they have multiple generations per year, seasonally fluctuating selection is a potentially powerful mechanism to maintain polymorphism However, previous research has argued that this occurs rarely
