Examining Plant Physiological Responses to Climate Change through an Evolutionary Lens1[OPEN]
Integrating knowledge from physiological ecology, evolutionary biology, phylogenetics, and paleobiology provides novel insights into factors driving plant physiological responses to both past andExpand
Identifying targets and agents of selection: innovative methods to evaluate the processes that contribute to local adaptation
A literature review of studies that mapped quantitative trait loci for fitness in native field environments using reciprocal transplant experiments with hybrid mapping populations or Genome-wide Association Study (GWAS) panels found that local adaptation is more often caused by conditional neutrality than genetic trade-offs at the level of the QTL. Expand
Integrating viability and fecundity selection to illuminate the adaptive nature of genetic clines
The results indicate that genetic clines are maintained by selection, but their expression is context dependent, as they do not emerge in all environments, and suggest that reconciling clinal trait variation with selection requires data collected across multiple spatial scales, time frames, and life‐history stages. Expand
The shape of selection: using alternative fitness functions to test predictions for selection on flowering time
The experimental results strongly supported selection for early flowering in short season and selection for late flowering in long season conditions, and found support for the predicted asymmetry of the flowering time fitness function, including a ‘tail of zeros’ at later flowering dates. Expand
Climate change disrupts local adaptation and favours upslope migration.
It is revealed that low elevation populations risk rapid decline, whereas upslope migration could enable population persistence and expansion at higher elevation locales, and local adaptation to historical conditions could increase vulnerability to climate change. Expand
Hard and soft selection on phenology through seasonal shifts in the general and social environments: A study on plant emergence time
A novel adaptation of contextual analysis to partition total selection into the hard and soft components was devised, finding that hard andsoft components had similar strengths at low density, whereas soft selection was five times stronger than hard at high density. Expand
Phenological mismatch and the effectiveness of assisted gene flow
A method to estimate the frequency of resident × migrant matings based on flowering schedules was devised and applied in an experiment that mimicked the first generation of an AGF program with Chamaecrista fasciculata, a prairie annual, under current and expected future temperature regimes, reducing the potential for resident × migrants matings by 40-90%, regardless of thermal treatment. Expand
Phenological responses to multiple environmental drivers under climate change: insights from a long-term observational study and a manipulative field experiment
It is found that variation in phenological responses to climate change depended on the sequence in which species flowered, with early-flowering species flowering faster, at a lower heat sum, and under increasingly disparate photoperiods in comparison to species that flower later in the season. Expand
Phenological responses to multiple environmental drivers under climate change: insights from a long-term observational study and a manipulative field experiment.
Early snow-removal treatments confirm that the timing of snowmelt governs observed trends in flowering phenology of B. stricta and that climate change can reduce the probability of flowering, thereby depressing fitness. Expand
The success of assisted colonization and assisted gene flow depends on phenology.
Global warming will jeopardize the persistence and genetic diversity of many species. Assisted colonization, or the movement of species beyond their current range boundary, is a conservation strategyExpand
