Abstract

The ecology, especially the macro-ecology, of rust fungi, and the distribution of the species was studied in Lammi commune; the species numbered 108. The distance between the hosts of some rusts was studied. The phenology of the rusts shows a relation to the macroclimate at the community level and to the microclimate at the species level. Factors affecting the phenology are discussed; every species has its own phenological code. Occurrence in different habitats was studied. Man has clearly influenced the distribution by his agricultural and silvicultural activities. Some rust species are most abundant on roadsides, others in shady places. The rusts are classified in relation to the influence of man. The factors affecting the occurrence of rusts in some manmade habitats are discussed. The macro-ecology of the rust fungi is outlined and their ecological amplitudes are discussed.
