Blocked Swapping A. The clathrin lattice forms at the site of membrane invagination (1). Underneath the lattice accessory proteins come and go (2), each driving a different step in the invagination and vesicle-forming process (3). B. When a pitstop binds clathrin (1), it prevents these accessory proteins from binding to clathrin, and endocytosis stops.Precision graphics

THE PETER LAKE FOOD WEB Originally, the food web was dominated by minnows eating zooplankton such as water fleas, which survive by consuming tiny water-borne plants. The few largemouth bass in the lake fed on the minnows. But tweak the top of the chain and an ecosystem shift ensues: the increasingly numerous bass devastated the minnow population, leading to large swings in phytoplankton amounts until the food web settled into its new state.
