Walking through nature with John Palka, a neuroscientist who loves plants and ponders big questions
We know from experience about the way we humans court, and make babies, and care for our children. It’s a huge part of our lives. But how about some of the other creatures that make up the living world? How do they bring the next generation into existence?
This past Sunday was Easter Sunday. It evoked in me many thoughts and feelings about Nature which I would like to share with you here.
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!
