Flowers Losing Their Scent

A new study shows that pollution from car exhaust is to blame for flowers and plants losing their scent all over the world.  Bees and other insects cannot pollinate plants if they can't find them.  Coupled with the recent catastrophic decline in bee populations across the globe, the study has determined that a disturbing cycle of dying insects, and plants that can't reproduce is underway, and its a downward spiral that threatens the world's food supply.

German bee die-off

"Bees in the German state of Baden-Württemburg are dying by the hundreds of thousands. In some places more than half of hives have perished. Government officials say the causes are unclear -- but beekeepers are blaming new pesticides."

This isn't being linked to the Colony Collapse Disorder that continues to ravage hives in the US. Different circumstances, but the same high level of devastation.

 

Yes it does!

Hemp is primarily a dioecious plant, which means that male and female reproductive organs are produced on separate plants. Thus in order for the female plant to produce seeds it must be pollinated.  Pollination can occur through many different means either biotic (bees, insects, birds) or abiotically (wind, rain, etc). However, the flowers of a male hemp plant are not at all attractive to pollinators such as bees, so most pollination of this plant occurs through abiotic factors anyway.

But! in the event of a biotic pollination crisis the hemp plant has yet another defense mechanism. It is one of several plants that also produces monoecious species (which means that both male and female parts are on the same plant). Pollination for these plants is much easier because male pollen does not have far to travel to get to female organs. Monoecious pollination is also abiotic.  

So, here's to hemp for being one of the most versatile plants this earth has been graced with!

The honey bee population seems to be stong in south central Tennesse this year. Flowering clover fields are attracting good numbers, far better than last year. Also seeing lots of Yellow-Jackets, Hornets, Carpenter & Bumble Bees.

Neonicitinoids

I watched a documentary on this problem about... 6 months ago and it pointed to the introduction of neonicitinoids as a form of pest control in causing CCD.
