History of botany scope of the subject as technology has opened up new techniques and areas of study. Modern molecular systematics, for example, entails the principles and techniques of taxonomy, molecular biology, computer science and more. Within botany there are a number of sub-disciplines that focus on particular plant groups, each with their own range of related studies (anatomy, morphology etc.). Included here are: phycology (algae), pteridology (ferns), bryology (mosses and liverworts) and palaeobotany (fossil plants) and their histories are treated elsewhere (see side bar). To this list can be added mycology, the study of fungi, which were once treated as plants, but
Dietary biology of the golden eagle in the French Pyrenees, the Italian Alps and Bulgaria. There is no information on how golden eagles capture insects or what kind of insects they hunt, although slower, larger, terrestrial insects like large beetles seems likely. One of the most fascinating, though relatively little studied, aspects of the golden eagle's biology is how it interacts with other predators in a natural environment, especially other large predatory birds. The golden eagle is a powerful hunter with few avian rivals in size or strength, although what it gains in these areas it loses somewhat in its agility and speed. Golden eagles are
