Have you ever wondered where pollinators go in winter? Most of us think of pollinators in spring and summer, when crops and wildflowers are in bloom and bees, wasps and butterflies are everywhere. Media coverage of pollinators peaks in spring months, and most studies of pollinator activity in crops and natural ecosystems are carried out during flowering in spring or summer, for obvious reasons.

Wild pollinator insects, especially bees, like diversity in their life. It’s not that they’re fussy, they just like to have different resources for nesting and foraging to choose from – just like us. This diversity in resources is important because wild pollinator communities aren’t just made up of bees, they include multiple species. We’ve (almost) figured out what honeybees like, and it’s easy to accommodate one species when you know the ins and outs of their biology. But ‘wild pollinators’ could mean solitary bees, bumblebees, huge hairy flies, delicate wasps, tiny midges, thrips, beetles, bugs, weevils, moths or butterflies. Some of these insects, particularly wasps and flies, may also control outbreaks of herbivorous insects, so they can provide multiple ecosystem services. Continue reading
I saw an article today in the journal Energy and Environmental Science that claims to have the answer to the biofuel problem. Apparently agave, the plant that has provided a sugar alternative, rope, food, soap and tequila to centuries of human communities, has a bright new future as a bioethanol producer.
Biofuels are one of those contentious issues that everyone loves to argue about, so as to procrastinate the task of actually doing something about our increased fuel consumption. They’re wonderful in concept (plants take up CO2 from the atmosphere and then provide a ‘natural’, ‘renewable’, non-fossilised fuel source), but come with a whole suite of problems and unanswered questions, just like every other ‘quick-fix’ solution we’ve come up with in the past (and haven’t learnt from).
