Temperature-dependence and genetic variation in resource acquisition strategies in a model freshwater plant

This study examines how heat stress affects genetic variation in resource acquisition traits in duckweeds, finding increased R* values and reduced genetic variation under high temperatures.

Lagged climate-driven range shifts at species' leading, but not trailing, range edges revealed by multispecies seed addition experiment

The paper uses a seed addition experiment to test lagged climate responses and microclimatic buffering in plant range shifts, finding support for lagged responses over microclimatic buffering.

Range expansion is both slower and more variable with rapid evolution across a spatial gradient in temperature

This study shows that range expansion is slower and more variable with rapid evolution across a temperature gradient, challenging current theory about predictability.

Phenotypic lags influence rapid evolution throughout a drought cycle

The paper examines how phenotypic lags affect rapid evolution during a drought cycle by analyzing climate metrics across multiple years in Mimulus cardinalis populations.

Density-dependent selection during range expansion affects expansion load in life-history traits

The paper examines how density-dependent selection during range expansion interacts with allele surfing to affect genetic load and life-history trait evolution.

Selection on early survival does not explain germination rate clines in Mimulus cardinalis (Phrymaceae)

The study investigates whether a germination rate cline in Mimulus cardinalis is driven by local adaptation, finding no evidence that genetic variation in germination rate affects early survival.

Climate warming weakens local adaptation

The paper quantifies how climate change impacts population performance by analyzing temperature and precipitation effects, finding that local adaptation to temperature is critical and deviations reduce performance.

Variation in adaptation across geographic ranges is consistent with strong selection in marginal climates and legacies of range expansion

This study uses transplant data to show that populations at geographic range edges have varying adaptation levels, with poleward edges showing lower fitness and equatorial edges showing higher fitness relative to foreign populations.

Quantitative trait locus mapping reveals an independent genetic basis for joint divergence in leaf function, life-history, and floral traits between scarlet monkeyflower (Mimulus cardinalis) populations

This study maps quantitative trait loci (QTLs) for leaf, life-history, and floral traits in Mimulus cardinalis populations, finding no genetic coordination across trait categories and suggesting environmental selection drives trait syndromes.

Grow with the flow: a latitudinal cline in physiology is associated with more variable precipitation in Erythranthe cardinalis

This study identifies interannual precipitation variability as a selective agent driving a latitudinal cline in growth and photosynthesis in Erythranthe cardinalis.

Demographic compensation does not rescue populations at a trailing range edge

This study shows that demographic compensation does not prevent population decline at trailing range edges of scarlet monkeyflower due to reduced survival, growth, and recruitment despite increased reproduction.
