Flowers' Smell Not Traveling As Far

Ant writes in to note a study indicating that, because of air pollution, the smell of flowers is not wafting as far as it once did. Pollutants from power plants and automobiles destroy flowers' aromas, the study suggests: "The scent molecules produced by flowers in a less polluted environment, such as in the 1800s, could travel for roughly 1,000 to 1,200 meters; but in today's polluted environment downwind of major cities, they may travel only 200 to 300 meters." The finding could help explain why some pollinators, particularly bees, are declining in certain parts of the world.

    I still can't help but think that insecticides are having more to do with it. Bee keepers carry hives around to the farms. It's not like they have to fly too far to find the flowers, but hives are collapsing at farms.

    can't they just genetically engineer flowers with more potent aromas?

    then we will inevitably have a /. story about long delays getting the product developed, and the whole idea of new smelly flowers will get tagged as vaporware, which would be an entirely inappropriate tag.

      I have a super sense of smell. I can smell and identify an open can of V-8 in another room. But it's not all rosey at this extreme either (pun shamefully indulged in). As a result, some of our more volatile chemicals (like tar, household cleaners, etc) cause immediate headaches at just a wiff. Today there are tons of smells that just shouldn't be there. I'm not going to equate it to a mine field, but it's not great. But on occasion it is rewarding.

      My father lost his sense of smell after a car accident. I never realized how important it is. One day his van smelled like gas, but he didn't know. He had a leaky gas line. He can't smell my mom's perfume or what's for dinner. What he does taste is a combination of the four basic flavors.

      Smell is probably our most underrated sense.

      Dogs' noses are so good that they can't afford to find certain smells distasteful in the way we do - if they did it'd soon be absolutely unbearable for them anywhere near something icky.

      Our noses kinda make the decision about whether something is good/bad, for a dog any smell is just information. Like how our eyes just give us info about colours/shapes - we wouldn't recoil from a blue triangle in the way we do from sour milk.

      I suspect the smells dogs like are just the strongest smells or the ones with the most useful information to impart, which would explain the ass-sniffing and rolling in fox crap.

  5. Dumb conclusion... by TropicalCoder · · Score: 4, Insightful

    The finding could help explain why some pollinators, particularly bees, are declining in certain parts of the world.

    I don't need to RTFA to point out how this conclusion does not bare up to even superficial examination. We have two types of bees in this world - domestic and wild. Bees in the wild are likely far from sources of pollution - by definition of "in the wild". Domestic bees are well known to be currently suffering a crises due a disease (or is it bee mites - or both?). What bees remain that are both not "in the wild" and not domestic are the only ones to potentially fit to the above conclusion. I would suggest that this is a very small group. I suppose other pollinators - like butterflies, etc, may find it a bit more difficult to find their flowers these days, but on the other hand, one would logically find these insects near flowers in the first place - their place of birth. Same goes for domestic bees, which are cultivated near flowering crops.

      The problem seems to be not drowning the scent in other scents, but the destruction of scent molecules by pollutants. Insects have a very low scent threshold and can detect a scent trail of just a few specific molecules, so drowning wouldn't be a problem.

  9. Coming soon - stronger scents? by gregor-e · · Score: 3, Interesting

    If pollution is degrading aroma molecules before pollinators can pick up on them, this is a selective pressure for plants to produce more scent or at least more durable scents. Given that peppered moths have been able to change from light to dark and back to light coloring in less than a century, I'd expect we'd already be seeing (or smelling) stronger-scented flowers.

      They would need to produce molecules which are not destroyed by pollutants. Being able to generate those in a really short time is tough. Even for as big a laboratory as the earth.

    Nonsense. They're suggesting that the relevant effects from pollution aren't just local in the area of the polluters. Furthermore, colony collapse disorder, which is the crisis you refer to, affects both wild and domestic bees and is very poorly understood - it's certainly not been proven to be due to disease or mites, and there's no good reason to immediately jump to the conclusion that the problem mentioned in the study isn't a major or even dominant factor in colony collapse disorder.

    Nonsense...there's no good reason to immediately jump to the conclusion that the problem mentioned in the study isn't a major or even dominant factor in colony collapse disorder.

    I don't see how you so easily can say "nonsense". I see it differently - that there is no good reason to immediately jump to the conclusion that the problem of Colony Collapse Disorder is caused by pollution. Colony Collapse Disorder seems to happen in sporadic bursts, whereas I believe pollution can be graphed with long graceful curves.

    Wikipedia says "...late in the year 2006 and in early 2007 the rate of attrition was alleged to have reached new proportions, and the term "Colony Collapse Disorder" was proposed to describe this sudden rash of disappearances." To me, that implies that there is no correlation between Colony Collapse Disorder and pollution, since I don't think there was a sudden spike in pollution that corresponds with declines in bee populations.

    Interestingly, I was just reading Boeing 787 Dreamliner Delayed Again, which links to a Wired Science article, which points to a Dan Rather video, which has a segment at the end that states that the cause of Colony Collapse Disorder has been determined to be caused by some Israeli bee virus. First time I heard that. I am certainly no expert, nor do I pretend to be. I was merely stating that for me, on the surface, the conclusion does not bear up to close scrutiny. In fact, I was implying that one doesn't need to be an expert, or even to RTFA to formulate a plausible critique.

    That's real interesting, but bees and many other pollinators find the flowers through the color. Granted, pollution may be diminishing the color, but I'm sure they can still find them. Once found, the bees give directions to the hive.
