- Lichen (Wikipedia)
A lichen (/ˈlaɪkən/ LY-kən, UK also /ˈlɪtʃən/ LITCH-ən) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship. Lichens are important actors in nutrient cycling and act as producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails. Lichens have properties different from those of their component organisms. They come in many colors, sizes, and forms and are sometimes plant-like, but are not plants. They may have tiny, leafless branches (fruticose); flat leaf-like structures (foliose); grow crust-like, adhering tightly to a surface (substrate) like a thick coat of paint (crustose); have a powder-like appearance (leprose); or other growth forms.
- Hans Hermann von Katte (Wikipedia)
Hans Hermann von Katte (28 February 1704 – 6 November 1730) was a Lieutenant of the Prussian Army, and a friend, tutor and possible lover of the future King Frederick II of Prussia, who was at the time the Crown Prince. Katte was executed by Frederick’s father, the Prussian King Frederick William I, when Frederick plotted to escape from Prussia to Britain. It was possible that Frederick intended to defect to the service of the British King George II (his maternal uncle) and possibly return to Prussia to depose his father.
