Walking through nature with John Palka, a neuroscientist who loves plants and ponders big questions
We have been on many a walk together—in forests, on beaches, on the prairie. But let’s go out again, for there is still much to see and much to learn about life on the extraordinary planet that is our home. Today, let’s look for lichens!
For those of us who live in the Northern Hemisphere, the Winter Solstice is approaching. The days are gradually getting shorter while the dark of the nights is lasting longer. After December 21st, the shortest day of the year, the days will start to lengthen again, at first imperceptibly and then more noticeably.
More than anything, autumn is the season of brilliant colors, and most of us are immediately drawn to them. However, as much as we relish them, the colors can also prompt us to ponder. In one of the earliest posts on Nature’s Depths, “Our Brightly Colored World” (November 29, 2015), almost exactly four years ago, we asked, where do colors come from and how do we get to see them? Let’s look at that question again now, and then take it further.
Today we will look at two ways in which the whole planetary context in which flowers and their pollinators live affects their lives. I think you will be surprised!
The paths that fan out from the Eastman Nature Center near our home in Maple Grove, Minnesota, continue to be a source of inspiration for me. I go walking there almost every day, and each time something new catches my eye and finds its way into my camera.
The last piece I wrote for Nature’s Depths, dated November 24, 2019, bore the name “Beauty and Love.” Almost exactly eight months have passed since then, eight months since my beloved of sixty years left this world, eight months since my life was permanently changed. And yet, some important things have not changed, and walking in Nature with open eyes, an inquisitive mind, and a responsive heart is one of them.
