Designed and executed a controlled breeding experiment across roughly 28,000 pea plants over eight years, tracking seven distinct heritable traits and applying statistical analysis to infer the existence of discrete units of heredity.

Co-founded the Austrian Meteorological Society in 1865 and maintained systematic meteorological measurements three times daily across multiple monastery locations for years.

Continued a correspondence and a redirected set of Hieracium plant experiments with botanist Carl Nageli for seven years, from 1866 to 1873, despite consistently discouraging results.

Sustaining this unproductive line of work for seven years is part of the basis for the profile's persistence score. Persistence
