3 thoughts on “Our Native Bees: North America’s Endangered Pollinators and the Fight to Save Them by Paige Embry (January book)

  1. I am sorry to say that I will not be able to make tomorrow’s get-together, but here are some of the things I would have said.

    Over all, the book was beautifully put together. The pictures were fantastic (and also creepy). Do the e-readers get the photos? If not, borrow a hard cover version to view them.

    Many of my comments or questions are “how do they know?” and I think she should have prefaced many of her points with “as far as we know.” “Every Franklin’s bee has historically lived within a 200 by 70 mile oval.”

    As far as the Greenhouses killed the Franklin Bee, I’d say be careful what you wish for. Unexpected results often occur.
    .
    Moving bees in and out of cultivated fields and taking them distances from their home to pollinate must be confusing to the bees. How does the bee keeper know when he’s got all his bees in the boxes to take them back home. Who counts the bees?

    Baby honey bees get fed 250 a day!!!

    How do you keep domestic bees from “escaping” to the wild. How do you keep them down on the farm once they’ve seen Paris.” (Sorry ’bout that.)

    The main thing I see about the bees is making sure that the right bee is in the right place at the right time. It’s amazing to me that the pollinators are so fussy about their pollen.

    Paige throws a lot of figures around, sometimes to the point I was getting confused. I can’t visualize that at any every given moment, we likely share the world with about ten quintillion individual insects.

    Overall, I enjoyed the book, although I wouldn’t want to read another “bee” book for awhile, I did learn a lot about pollination. I think I give the book a 4.

    Enjoy the discussion –

  2. Notes of bees that I found interesting:

    From: https://inhabitat.com/its-official-cell-phones-are-killing-bees/
    Scientists may have found the cause of the world’s sudden dwindling population of bees – and cell phones may be to blame. Research conducted in Lausanne, Switzerland has shown that the signal from cell phones not only confuses bees, but also may lead to their death. Over 83 experiments have yielded the same results. With virtually most of the population of the United States (and the rest of the world) owning cell phones, the impact has been greatly noticeable.
    Led by researcher Daniel Favre, the alarming study found that bees reacted significantly to cell phones that were placed near or in hives in call-making mode. The bees sensed the signals transmitted when the phones rang, and emitted heavy buzzing noise during the calls. The calls act as an instinctive warning to leave the hive, but the frequency confuses the bees, causing them to fly erratically. The study found that the bees’ buzzing noise increases ten times when a cell phone is ringing or making a call – aka when signals are being transmitted, but remained normal when not in use.
    The signals cause the bees to become lost and disoriented. The impact has already been felt the world over, as the population of bees in the U.S. and the U.K. has decreased by almost half in the last thirty years – which coincides with the popularization and acceptance of cell phones as a personal device. Studies as far back as 2008 have found that bees are repelled by cell phone signals.
    Bees are an integral and necessary part of our agricultural and ecological systems, producing honey, and more importantly pollinating our crops. As it is unlikely that the world will learn to forgo the convenience of cell phones, it is unclear how much they will contribute to the decline of bees, and their impact on the environment.

    From: https://inhabitat.com/its-official-cell-phones-are-killing-bees/
    https://www.defendershield.com/disappearing-birds-bees-dire-ecological-effects-emf-saturation/
    Bees are relatively small and often unappreciated animals, but they do a whole lot for us. Through their daily buzzing from flower to flower, bees ensure the survival of 90 percent of the world’s wild plants and more than 30 percent of the food crops we eat (apples, citrus fruits, berries, onions, broccoli, almonds, and avocados, to name a few). And of course, we can’t forget about the honey they tirelessly produce. According to USDA reports, in 2017 2.7 million honey-producing colonies made 1.5 million pounds of raw honey.
    Environmental factors
    Climate change, widespread use of pesticides and genetically modified crops, and habitat change/loss all play a role. There is also mounting evidence that the global adoption of EMF (Electromagnetic Field) radiation-emitting wireless technology is partially to blame.
