Human impacts are causing alarming levels of harm to our planet. As scientists who study the interaction of people with the rest of the biosphere using a wide range of approaches, we agree that the evidence that humans are damaging their ecological life-support systems is overwhelming. We further agree that, based on the best scientific information available, human quality of life will suffer substantial degradation by the year 2050 if we continue on our current path. Science unequivocally demonstrates the human impacts of key concern: • Climate disruption — more, faster climate change than since humans first became a species • Extinctions — not since the dinosaurs went extinct have so many species and populations died out so fast, both on land and in the oceans. • Wholesale loss of diverse ecosystems — we have plowed, paved, or otherwise transformed more than 40% of Earth’s ice-free land, and no place on land or in the sea is free of our direct or indirect influences.

His work has profoundly influenced our understanding of how populations in nature persist and how conservation policy for endangered species should be implemented. Ilkka Hanski is one of the foremost ecologists of his generation. His highly original contributions to both theoretical and observational experimental work in ecological science have had a deep and wide-ranging impact. More than any other ecologist, Ilkka Hanski has been responsible for the development of the concept of “metapopulations”, one of the most influential ideas in late twentieth century population ecology. Many species in nature exist as “metapopulations”. A metapopulation is a series of semi-isolated populations linked by occasional migration between them. What Ilkka Hanski has done, building on an idea put forward by Richard Levins, is to show how the persistence of populations often depends critically on the way in which they are divided into sub-groups.

Such a regime shift demonstrates a system’s resilience that characterizes the ability of a system to adjust its activity to retain its basic functionality in the face of internal disturbances or external environmental changes. In the past 50 years, attention was almost exclusively given to low dimensional systems and calibration of their resilience functions and indicators of early warning signals without considerations for the interactions between the components. Only in recent years, taking advantages of the network theory and lavish real data sets, network scientists have directed their interest to the real-world complex networked multidimensional systems and their resilience function and early warning indicators.

D. 2017: Ilkka Hanski, The “Compleat Ecologist”: an homage to his contributions to the spatial dimension of food web interactions. — Ann. Zool. Fennici 54: 51–70. Ilkka Hanski is most widely known for his seminal contributions to metapopula- tion ecology, both theoretical and empirical. But he also made many important and wide-ranging contributions to other arenas of ecological inquiry, including in partic- ular predator–prey, host–parasitoid, and host–pathogen interactions. This paper pro- vides an overview of his work in trophic ecology, ranging from individual behavior of foraging predators and fleeing prey, up to effects of spatial patchiness on the per- sistence of specialist natural enemies, and even the determinants of food chain length. In recent years, his work on food web interactions took on an increasingly genetic and evolutionary slant. In this paper, I also return to two theoretical models that I discussed over the years with Ilkka, where we contemplated carrying out collaborative work, but never managed to do so. The first of these models involves how habitat patchiness might moderate apparent competition between prey species.
