Walking through nature with John Palka, a neuroscientist who loves plants and ponders big questions
The Peregrine Falcon W/Z is part of a large, ongoing raptor (bird of prey) monitoring effort being conducted on the southwest coast of the Olympic Peninsula of Washington by a dedicated non-profit group called Coastal Raptors, based in Hoquiam. Here is how we got to meet him.
When we walk through a forest, we are surrounded by trees growing up toward the sky. . . Most are primarily straight. . . Some are twisted in complex ways, but even these grow mostly upward from the surface of the soil. What mechanisms generate the upward growth that is so characteristic of most trees, and indeed the great majority of all land plants?
You can specify the differences among various tree species, but if you focus on properties that they share, rather than on properties that distinguish them, you quickly realize that vertical growth characterizes the vast majority of trees, and indeed the vast majority of all plants. How does upward growth come about?
What is the life that we work so hard to sustain? The answer is not at all simple, even from a strictly scientific point of view, so let us approach it in steps.
Though flowers affect us deeply, they are the products of evolution and play their own role in the great web of life. This role is independent of human feelings. Flowers are what they are. . . It seems only right that we should examine them closely on their own terms.
Walking in the western woods in springtime, from Alaska to California, you may notice flashes of brilliant yellow coming from what look like big flowers. What you are seeing is Lysichiton americanum, commonly known as swamp lantern or western skunk cabbage. Both names for these spectacular plants are highly appropriate.
