A University of Michigan study found that morning glories adapt slowly to climate change because they prioritize attracting pollinators. This trade-off results in a 96% decrease in adaptation rate over nine years.

Scientists at the University of Michigan studied how morning glories, a common weed, adapt to changing environments. They observed a significant decline in adaptation rate over nine years, with a staggering 96% drop.

The researchers grew morning glory seeds collected from wild populations and recorded various plant traits, such as flower size and flowering time. They found that the need to attract pollinators with larger flowers is winning out over adapting to climate change. This means that plants are becoming locked into a trajectory that favors pollinator attraction, potentially at the expense of climate adaptation.

The study's lead researcher, Sasha Bishop, explained that this trade-off is happening even though newer plant populations have plenty of genetic variation. They should be able to adapt normally, but instead, they're stuck in a situation where they prioritize attracting pollinators over adapting to climate change.

Why It Matters

This study matters because it shows how plants are adapting (or not adapting) to climate change and the impact on farmers who deal with morning glories as an agricultural nuisance. It also highlights the importance of understanding the complex relationships between plants, pollinators, and climate change.

Key Facts

• A University of Michigan study found a 96% decrease in adaptation rate of morning glories over nine years.

• This trade-off affects farmers who deal with morning glories as an agricultural nuisance.
• The study was published in the journal Evolution Letters.

Key Terms

Pollinator pressure

The force that plants face to attract pollinators, such as bees and butterflies.

Adaptation rate

How quickly a plant population adapts to changing environments.

Genetic variation

The diversity of genes within a plant population that allows them to adapt to different conditions.
