The measurement of fitness is critical to biological research. Although the determination of
fitness for some organisms may be relatively straightforward under controlled conditions, it is …

Meta‐analysis is increasingly used to synthesize major patterns in the large literatures within
ecology and evolution. Meta‐analytic methods that do not account for the process of …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

Studies of phenotypic selection document directional selection in many natural populations.
What factors reduce total directional selection and the cumulative evolutionary responses to …

To understand evolutionary factors that maintain complex trait variation, we sequenced
genomes from a single population of the plant Mimulus guttatus, identifying hundreds of …

Decades of observation in natural plant populations have revealed pervasive phenotypic
selection for early flowering onset. This consistent pattern seems at odds with life‐history …

Species inhabit complex environments and respond to selection imposed by numerous
abiotic and biotic conditions that vary in both space and time. Environmental heterogeneity …

Flowers exhibit amazing morphological diversity in many traits, including their size. In
addition to interspecific flower size differences, many species maintain significant variation …

Alpine plants are at high risk because of climate change. Assessing the performance of
alpine plant species across different altitudes is useful for predicting how they may respond …

Female meiotic drive, in which chromosomal variants preferentially segregate to the egg
pole during asymmetric female meiosis, is a theoretically pervasive but still mysterious form …
