Climate change is forcing plants to abandon pollinators

Using genetic analysis, behavioural tests with bumblebees and observations of flower appearance, the team uncovered unexpected trends. It turned out that modern flowers produced 20 per cent less nectar and were also less likely to be visited by pollinators than plants grown from old seeds.

The rapid changes in plants are thought to be linked to a huge decline in flying insect populations. The researchers even believe this may be part of a vicious cycle: fewer insects lead to less nectar production in flowers, which means the insects have less food to eat and their numbers decline.

The team emphasises the importance of finding practical measures to protect the vital relationship between pollinators and plants.
