A Decline of Bees Threatens Evolution of Plants, Study Suggests.

There are plenty of studies to show the population of Bumblebees are declining and what this could mean for the flowers and plants of the world and in turn what it could mean for all of the life on the planet.

Well, a study was done to compare the differences in a type of plant that had been pollinated by a bee and another by a hoverfly. The results showed that the plants that were only pollinated by the bees grew to almost twice the height and were twice as highly scented as the plants that had only been pollinated by the hoverfly.

So, what conclusion can we draw from this then?

If the bees die out and we’re left with only with hoverflies then we will have less prolific plants and flowers with less scent.

But, what’s also interesting is that the plants that were pollinated by the hoverflies had a 15-fold increase in the ability to self-pollinate.

What this means is that the plant doesn’t have any chance of variation, or in other words evolve (something I have talked about previously).

With no variation, the plant will have a less of a chance to fight off diseases or pests etc. It will also mean that the plant cannot grow bigger, taller, or stronger than others and therefore be stunted with a disadvantage. Bad for long term crop growth.

The conclusion drawn by the scientists that undertook the study says “Bees aren’t the only pollinator, but many plants will not thrive if they are only visited by other insects, as this new research shows,”

I would like to add to that by saying that we should be using fewer pesticides and pollutants, anything that damages the life of bees rather than trying to make better pesticides etc. Using less of the bad stuff, instead of more expensive refining of the bad stuff to make it less bad? If that helps.

Looking at it this way, it would be like fixing the problem at the well, rather than buying an expensive new sink.
