Dear colleagues, we are organizing a symposium 'Evolutionary rescue: theory, data, and pressing applications' at the 3rd Joint Congress on Evolutionary Biology, which is taking place July 26-30 in Montreal, Canada (https://www.evolutionmeetings.org/). Registration for the conference has just opened. The goal of the symposium is to bring together theoreticians and empiricists working on fundamental and applied questions on evolutionary rescue. A slightly more detailed symposium description is given below. If you do research on evolutionary rescue, we would be very happy if you submitted an abstract to our symposium! Talks that are not selected for a symposium will (in contrast to ESEB congresses) nevertheless be accepted for the conference and be placed in one of the general sessions. Please don't hesitate to contact us if you have any questions.

In conservation this is desired, in agriculture (pesticide resistance) and medicine (drug resistance) it is often not. To better understand and manage evolution's effect on persistence there has now been nearly 30 years of research under the banner of "evolutionary rescue", ranging from mathematical models to experimental tests to natural observations. The increasing threats of climate change and drug resistance are only accelerating these efforts. In an attempt to unite and propel the growing field of evolutionary rescue, this symposium aims to bring together researchers across basic science, conservation, agriculture, and medicine.
