Crozier (mycology) Crozier (mycology) A crozier is an anatomical feature of many fungi in the phylum Ascomycota that form at the base of asci and look like hook-topped shepherd’s staffs or stylized religious crosiers. During the ascus initial formation the crozier helps to maintain a dikaryotic state in the ascus initial and its side branch that will continue the spreading growth of the ascogenous hyphae in Ascomycota fruitbodies. The tips of developing asci on these ascogenous hyphae curl over. One haploid nucleus migrates into the curved tip while the other compatible haploid nucleus remains in the penultimate space below the hook. The
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
