Document Summary
Lecture 24 species interactions in subalpine meadows. Distribution and abundance, patchiness of natural systems ecology. The glacier lily flowers are concentrated around places where there is a lot of surface rock or rock outcrop where they organic surface is super thin. This plant is a long-lived perennial, grows for a short time during spring (like a spring ephemeral), and stores the year"s resources in its corm. If it gets pollinated, it makes a large fruit capsule containing seeds. Big seeds are made, and need to be dispersed based on the janzen-connell hypothesis. Tanglefoot used to see how far the seeds went. The seeds stay in the vicinity of parent plant. This is strange because other lilies have some form of dispersal for example, an elaiosome attached to a seed which is very tasty for ants so they eat the elaiosome and dump it in their trash which is nitrogen-rich.
