    Are Missing Love Bugs a Warning Sign?

    Missing Love Bugs in Florida. E. Hall (2024, May)
    with (very) little help from DALL-E (OpenAI).

    As we go into Love Bug season in May,
    seeing no lovebugs may leave us all
    with mixed emotions:
    happiness and dismay! 

    [There have been some lovebug sightings, but not many… Let’s see how the season goes.]

    This is one of our GenAI assisted articles using an approach we call Regenerative Dynamic AI. (You can redo with your favorite GenAI at any time and link through to dynamically updated sources like Wikipedia: Lovebugs.)

    You: What happened to the lovebugs in Florida?

    University of Florida entomologist
    Norman Leppla
     has noticed the lack of lovebugs around the UF campus in
    Gainesville as well. However, the exact cause remains a bit mysterious.
    Lovebugs are quite sensitive to moisture and temperature, which
    makes their population dynamics closely tied to climate and weather conditions.
    Florida has experienced increasingly warmer temperatures, including one of its
    hottest summers on record. Lovebug larvae live on top of the soil, and extreme
    weather conditions could either “cook or drown” them.

    While there’s no direct link between the weather and the
    decline in lovebugs, several factors could be at play, including pollution,
    climate change, predators, or parasites. These little bugs might not be native
    to Florida, but any change in their behavior could signal something awry in
    nature. After all, we’re all
    interconnected, and environmental stresses affect us too
    1.

    So,
    the mystery of the disappearing lovebugs continues, leaving us with sticky
    windshields and a few unanswered questions. 🐞🚗

    You:  Where are
    lovebugs native to?

    You: Related to lovebugs. Are lovebugs possibly the
    “canary in the coal mine” for other animals, bugs, plants? 

    Copilot
    (2024, May)

    Lovebugs,
    scientifically known as Plecia nearctica, are fascinating creatures
    found in parts of Central
    America
     and the southeastern
    United States
    , especially along the Gulf CoastThese
    small insects are also affectionately called “honeymoon flies” or “double-headed bugs” due
    to their unique mating behavior: matured pairs remain together, even in flight,
    for several days
    12.

    Now,
    let’s explore whether lovebugs could indeed be the “canary in the coal mine”
    for other organisms:

    1.     
    Indicator
    Species
    :

    2.     
    Environmental
    Sensitivity
    :

      • Lovebugs
        are sensitive to environmental conditions, particularly moisture
        and temperature
        .
      • Their
        population dynamics closely correlate with climate and weather changes.
      • Extreme
        weather conditions (such as excessive heat or heavy rain) can impact
        their survival.
      • If
        lovebugs experience fluctuations due to environmental stressors, it could
        signal broader ecological shifts.

    3.     
    Interconnected
    Ecosystems
    :

      • Lovebugs
        interact with various components of their environment, including plants,
        soil, and other insects.
      • Changes
        in their behavior or abundance may have ripple effects on other species.
      • For
        example, if lovebugs decline significantly, it could affect pollination,
        nutrient cycling, or food webs.

    4.     
    Cautionary
    Tale
    :

      • While
        lovebugs themselves might not directly represent imminent ecological
        collapse, their decline serves as a cautionary tale.
      • It
        reminds us to pay attention to subtle changes in our environment.
      • Just
        as the canary in the coal mine warned miners of toxic gases, lovebugs
        could serve as an early warning system for broader ecological imbalances.

    In
    summary, while lovebugs alone may not be the sole indicator, their sensitivity
    and interconnectedness highlight the need for vigilance in monitoring and
    protecting our ecosystems. Let’s appreciate these little bugs as more than just
    windshield nuisances—they might be whispering messages about our environment!

     

  • Earth Day 2021 Quiz

    a.  4%-5%

    b.  10%-15%

    c.  25%-30%

    d.  40%-45%

    8.  Soil. The current “industrial” farming
    methods deplete the topsoil. No topsoil, little or no farm crops. At the
    current rate of topsoil depletion, how many years do we have before we “run
    out” of topsoil? [Ooops…. Things changed… problems with this question… Well, with the answers…]

    11.  What is the depth of the oceans? (Plus, water
    expands when warmed about 0.000214 per +1C for seawater, so how much would sea
    levels rise based on a +1 degree Centigrade increase in global temperature that
    transferred throughout the oceans.)

    a.  Average ocean depth is 1,000ft (+1C temp
    increase = +2.6in increase in avg ocean level.)

    b.  Average ocean depth is 2,500ft (+1C temp
    increase = +6.4in increase in avg ocean level.)

    c.  Average ocean depth is 1.2 mile (+1C temp
    increase = +16.3in in increase avg ocean level.)

    d.  Average ocean depth is 2.3 miles (+1C temp
    increase = +31.2in increase in avg ocean level.) 

  • Sixth mass extinction is here, researcher declares.

    Sixth mass extinction is here, researcher declares:

    Ouch. It looks like we need to clean up our collective acts. With 41% of amphibians and 26% of mammals on a course for extinction if we don’t change our ways.

    “To history’s steady drumbeat, a human population growing in numbers, per capita consumption and economic inequity has altered or destroyed natural habitats. The long list of impacts includes:

    *Land clearing for farming, logging and settlement

    *Introduction of invasive species

    *Carbon emissions that drive climate change and ocean acidification

    *Toxins that alter and poison ecosystems

    Now, the specter of extinction hangs over about 41 percent of all amphibian species and 26 percent of all mammals, according to the International Union for Conservation of Nature, which maintains an authoritative list of threatened and extinct species.

    “There are examples of species all over the world that are essentially the walking dead,” Ehrlich said.”
