We live amid a global wave of anthropogenically driven biodiversity loss: species and
population extirpations and, critically, declines in local species abundance. Particularly …

Abstract The 2019 United Nations Global assessment report on biodiversity and ecosystem
services estimated that approximately 1 million species are at risk of extinction. This …

Despite evidence of pollinator declines from many regions across the globe, the threat this
poses to plant populations is not clear because plants can often produce seeds without …

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 …

Evolutionary rescue occurs when adaptive evolutionary change restores positive growth to
declining populations and prevents extinction. Here we outline the diagnostic features of …

Experimental evolution is the study of evolutionary processes occurring in experimental
populations in response to conditions imposed by the experimenter. This research approach …

Local extinctions have cascading effects on ecosystem functions, yet little is known about the
potential for the rapid evolutionary change of species in human-modified scenarios. We …

Pollinator-driven diversification is thought to be a major source of floral variation in plants.
Our knowledge of this process is, however, limited to indirect assessments of evolutionary …

Floral traits are hypothesized to evolve primarily in response to selection by pollinators.
However, selection can also be mediated by other environmental factors. To understand the …

Fragmentation—the process by which habitats are transformed into smaller patches isolated
from each other—has been identified as a major threat for biodiversity. Fragmentation has …
