pollinators?
A flower produces nectar to attract bees.
A plant produces thorns to deter herbivores.

Doug Schemske is a biologist who studies plants from around the world. Doug and his research team carry out experiments with the plant species Mouse-ear Cress, or Arabidopsis thaliana. They like this species because it is easy to grow in both the lab and field. Arabidopsis is very small and lives for just one year. It grows across most of the globe and in a wide range of latitudes and climates. Arabidopsis is also able to pollinate itself and produce many seeds, making it possible for researchers to grow many individuals to use in their experiments.
Doug chose Arabidopsis populations in Scandinavia and the Mediterranean for his research on local adaptation because those two locations have very different climates. The populations may have adapted to have the highest survival and reproduction based on the climate of their home location.
To deal with sudden freezes and cold winters in Scandinavia, plants may have evolved freeze tolerance traits, which produces chemicals that act like…
