More to bees than queens and honey

11 02 2011

Another great guest post, this time from Tobias Smith, a PhD candidate at the University of Queensland’s School of Biological Sciences. Tobias is investigating bee community shifts across a fragmented tropical landscape in far north Queensland, aiming to identify landscape variation in community composition of two important rainforest pollinator groups, bees and flies. I met Tobias a few years ago as part of the Thiaki rainforest reforestation project for which he is doing baseline surveys of bees and flies.

I asked him a while ago to write a ‘primer’ on bees for since so many people really don’t much about the taxon (I include myself in that group). He’s done a brilliant job – everything you wanted to know about bees but were afraid to ask (in 1000 words).

The frequently reported, gloomy news about bee declines is hard not to notice. Bees are in dire trouble around the world, and this trend has worrying implications for both ecosystems and human food production. As a result, popular media often reports on the plight of bees, regularly reciting the figure of one in three mouthfuls of food being dependent on the work of bees. While bees certainly are in major trouble, it can be easy to misinterpret statements often made in these kind of articles without a little general bee knowledge. So here are a few bee facts that, at the very least, we ecological representatives should be familiar with. This information should help give some perspective when interpreting bee news, and when engaging in exciting bee conversations at the shops.

There are approximately 20,000 bees species globally. Yet when most people think of bees they think of a single species, Apis mellifera, the western honey bee (introduced in most of its range, and also referred to as the European honeybee). This bee is certainly an important bee. It is managed as the usual pollinator of crops requiring biotic pollination, and it makes the honey we usually eat here in the developed world. Some say our domestication of this bee has been an important contributing factor in achieving the level of development that we humans have. There are however, about 19,999 other bee species out there, and most of them are very different to the western honeybee. Read the rest of this entry »
