He introduced the concept of "autecology" to explain the relationship of an individual plant with its external environment, and "synecology" to express relationships between plant communities and external influences.In 1910 with Charles Flahault (1852–1935), he released Rapport sur la nomenclature phytogéographique (Reports on phytogeographical nomenclature), and with Friedrich Gottlieb Stebler (1852-1935), he was co-author of Die besten Futterpflanzen, etc. (1883–1884), a work involving forage crop cultivation and economics. It was later translated into English, and published with the title, "The best forage plants: fully described and figured with a complete account of their cultivation, economic value, impurities and adulterants, &c" (1889). With geographer Johann Jakob Früh, he was co-author of a book on Swiss moorlands, titled Die Moore der Schweiz : mit Berücksichtigung der gesamten Moorfrage (1904).
