- 摘要：
- 1. Phenological adjustments are an important aspect of a population’s response to climate change. Changes in phenology can occur through either individual plasticity or evolutionary change within populations. Few studies have investigated both these processes in Arctic environments. 2. Using 42 years of individual and pedigree data, we evaluated the contribution of plasticity and evolution to variation in breeding phenology at a colony of a high Arctic sea-ice obligate seabird, Mandt’s black guillemot (Cepphus grylle mandtii). Mean clutch initiation (first egg in a clutch) advanced 7.8 days, and both environmental (snowmelt) and demographic (years of breeding experience) factors varied among years. 3. Earlier phenology was associated with earlier snowmelt and experienced mothers. Females advanced phenology at different rates as they aged but at similar rates in response to variation in snowmelt. Heritability of clutch initiation was negligible, and there was no evidence of evolution contributing to phenological changes. 4. Earlier laying was associated with increased annual number of fledglings and annual adult survival at the individual level suggesting that the phenological changes are adaptive and are driven by phenotypic plasticity, but not genetic responses. 5. We propose that species with a constrained breeding season (like many Arctic species) may have a limited ability beyond existing plasticity to respond to changing environmental conditions.

Data from: Local adaptation and evolutionary potential along a temperature gradient in the fungal pathogen Rhynchosporium commune

- 摘要：
- To predict the response of plant pathogens to climate warming, data are needed on current thermal adaptation, the pathogen’s evolutionary potential and the link between them. We conducted a common garden experiment using isolates of the fungal pathogen Rhynchosporium commune from nine barley populations representing climatically diverse locations. Clonal replicates of 126 genetically distinct isolates were assessed for their growth rate at 12°C, 18°C and 22°C. Populations originating from climates with higher monthly temperature variation had higher growth rate at all three temperatures compared to populations from climates with less temperature fluctuation. Population differentiation in growth rate (Q_ST) was significantly higher at 22°C than population differentiation for neutral microsatellite loci (G_ST), consistent with local adaptation for growth at higher temperatures. At 18°C we found evidence for stabilizing selection for growth rate as Q_ST was significantly lower than G_ST. Heritability of growth rate under the three temperatures was substantial in all populations (0.58-0.76). Genetic variation was lower in populations with higher growth rate at the three temperatures and evolvability increased under heat stress in seven out of nine populations. Our findings imply that the distribution of this pathogen is unlikely to be genetically limited under climate warming, due to its high genetic variation and plasticity for thermal tolerance.
Data from: Genetic background and GxE interactions modulate the penetrance of a naturally occurring wing mutation in Drosophila melanogaster

- 摘要：
- Many genes involved in producing complex traits are incompletely penetrant. One such example is vesiculated, an X-linked gene in Drosophila melanogaster that results in wing defects. To examine the genetic architecture of a complex trait (wings containing vesicles), we placed a naturally occurring variant into multiple autosomal backgrounds and quantified penetrance and expressivity at a range of developmental temperatures. We found significant epistasis, genotype-by-environment interactions, and maternal effects. Sex and temperature effects were modulated by genetic background. The severity of wing phenotypes also varied across different genetic backgrounds and expressivity was positively correlated with penetrance. We also found evidence of naturally segregating suppressors of vesiculated. These suppressors were present on both the 2nd and 3rd chromosomes, and complex interactions were observed. Taken together, these findings indicate that multiple genetic and environmental factors modulate the phenotypic effects of a naturally occurring vesiculated allele.
