Introduction
I lead the Past Present Sustainability Research Unit (PAES) at the University of Helsinki. PAES focuses on understanding the ecological and climate related interlinkages with human activities in the present day and in the long-term historic past. The research perspective is from natural sciences and is enriched by interdisciplinary Post-docs and collaborations outside the core discipline.

Article
Full-text available
BACKGROUND: The pace and magnitude of human-caused global change has accelerated dramatically over the past 50 years, overwhelming the capacity of many ecosystems and species to maintain themselves as they have under the more stable conditions that prevailed for at least 11,000 years. The next few decades threaten even more rapid transformations be...

Full-text available
Recent renewed interest in using fossil data to understand how biotic interactions have shaped the evolution of life is challenging the widely held assumption that long-term climate changes are the primary drivers of biodiversity change. New approaches go beyond traditional richness and co-occurrence studies to explicitly model biotic interactions...
Article
The idea of decoupling “environmental bads” from “economic goods” has been proposed as a path towards sustainability by organizations such as the OECD and UN. Scientific consensus reports on environmental impacts (e.g., greenhouse gas emissions) and resource use give an indication of the kind of decoupling needed for ecological sustainability: glob...
Article
Full-text available
Large mammals are at high risk of extinction globally. To understand the consequences of their demise for community assembly, we tracked community structure through the end-Pleistocene megafaunal extinction in North America. We decomposed the effects of biotic and abiotic factors by analyzing co-occurrence within the mutual ranges of species pairs....
Article
Decoupling environmental ‘bads’ from economic ‘goods’ is a key part of policies such as green growth and circular economy that see economic growth as desirable or necessary, and also see that current use of natural resources and its environmental impacts is unsustainable. We estimate what a ‘successful decoupling’ (2% annual GDP growth and a declin...
Article
Full-text available
Since large-scale environmental disruptions have become chronic, policymakers need to consider the long-term consequences of urgent crisis decisions. We develop design principles for a decision platform addressing strategic environmental crisis management, by which we mean coordinated decisions during an environmental urgency that are sensitive to...
Article
Full-text available
As a part of its climate policy, Finnish government facilitated the creation of low-carbon roadmaps by sectors of industry. The roadmap process and the roadmaps were promoted as an international benchmark in COP26. They also form a part of the policy process towards the government's goal of carbon neutrality by 2035. We analyse the need and role of...
Technical Report
Full-text available
Finland has a unique potential to continue industrial production without fossil fuels. However, in order to achieve this situation, more raw materials and energy are required than is currently thought and is in line with strategic planning. In order for all fossil fuels (oil, gas, coal and peat) to be replaced at various sites in Finland, a large a...
Article
Full-text available
The magnitude and speed of change in complex human-environmental systems pose a systemic dilemma for societies. Human-induced environmental changes have pushed Earth's socio-ecological systems into an era of chronic, complex, and rapid disruptions, which call for quick intuitive decisions and effective implementation. Yet the complexity, interconne...

Suomen kaltaisia hyvinvointivaltioita pidetään lupaavina toimijoina kehityksessä kohti ekohyvinvointivaltiota, joiden tehtävänä on sopeuttaa taloudellinen ja sosiaalinen kehitys ekologisiin rajoihin. Tutkimuksessa on kuitenkin toistaiseksi kiinnitetty vain vähän huomiota teolliseen kestävyysmurrokseen ekohyvinvointivaltioiden ratkaisevana osa-aluee...
Chapter
Full-text available
Pastoralism is a globally -important livelihood, with large social, environmental and economic importance across much of our planet. Yet, it is also a vulnerable practice with widespread crises, urgently calling for better systemic understanding. The current disciplinary compartmentalization of research not only hampers this but allows perpetuation...
Article
Full-text available
In security and foreign policy discourse, environmental issues have been discussed increasingly as security threats that require immediate action. Yet, as the traditional security sector does not provide straightforward means to deal with climate change and other environmental issues, this has prompted concerns over undue securitisation and ill-pla...
Preprint
Full-text available
This article combines insights from ecological rationality and cultural evolution to illustrate how simple heuristics – colloquially, “rules of thumb” – have guided human behaviour and the evolution of complex cultures. Through a variety of examples and case studies, we discuss how human cultures have used rules of thumb in domains as diverse as fo...
Article
Full-text available
Historical records are incomplete templates for preparing for an uncertain future. The global utility of past ecological knowledge for present/future purposes is questioned as we move from Holocene to Anthropocene. To increase the adaptive capacity of today’s societies, generalizable strategies must be identified for coping with uncertainty over a...
Article
Pastoralism is globally significant in social, environmental, and economic terms. However, it experiences crises rooted in misconceptions and poor interdisciplinary understanding, while being largely overlooked in international sustainability forums and agendas. Here, we propose a transdisciplinary research approach to understand pastoralist transi...
Article
Full-text available
Climatic niches describe the climatic conditions in which species can persist. Shifts in climatic niches have been observed to coincide with major climatic change, suggesting that species adapt to new conditions. We test the relationship between rates of climatic niche evolution and paleo‐climatic conditions through time for 71 Old‐World flycatcher...

Katsauksessa tarkastellaan humanistisen ympäristötutkimuksen taustoja ja nykytilaa sekä suhteutetaan sitä yhteiskuntatieteelliseen ympäristötutkimukseen suomalaisessa ja kansainvälisessä tutkimuskeskustelussa. Koska suuntauksella ei ole vielä selkeää profiilia Suomessa, katsauksen pohjana on valikoima 2010-luvulla ilmestyneitä alan englanninkielisi...
Article
Full-text available
The late Quaternary of North America was marked by prominent ecological changes, including the end-Pleistocene megafaunal extinction, the spread of human settlements and the rise of agriculture. Here we examine the mechanistic reasons for temporal changes in mammal species association and body size during this time period. Building upon the co-occu...

Full-text available
Ecosystems are under unprecedented and accelerating pressures. Much work on understanding resilience to these pressures has, so far, focussed on the ecosystem. However, understanding a system’s behaviour also requires knowledge of its component parts and their interactions. Here we present a framework for understanding ‘biological resilience’, or t...
Article
The transition away from fossil fuel based infrastructure for heating and cooling has to happen on a scale and timetable with no historical precedent. As the systems are large and networked, path-dependencies constrain the transition that is further complicated by the diversity of stakeholders. Here we analyze the case of transitioning the district...

Full-text available
Ympäristövaikutusten irtikytkentää talouden koosta ja kasvusta on esitetty ratkaisuksi ekologisen kestämättömyyden ongelmaan. Irtikytkentä on myös “vihreän kasvun” ja kiertotalouden välttämätön taustaoletus. Kun arvioidaan, minkä kokoinen tehtävä onnistunut irtikytkentä Suomessa olisi ja miten nopeasti se pitäisi toteuttaa, huomataan sen olevan mah...
Article
Full-text available
Despite an increasing recognition that environmental change may have implications for security, there only are few policies to address the issue. This article will look at environmental security policies in Finland and Sweden and propose ways to develop more effective measures. It relies on a three-level framework that aims to enable the identifica...
Article
Full-text available
As the literature on environmental security has evolved and widened, knowledge of the full range of potential consequences of environmental change for different societies remains scattered. This article contributes to a more comprehensive approach to the implications of environmental change by providing a three-level framework of the security impac...

Conference Paper
Large mammals are at disproportionately high risk of extinction globally, and the ecological impacts of their loss will last beyond our lifetimes. Research shows that the end-Pleistocene mass extinction of large mammals left a significant ecological legacy, from shifting vegetation and fire regimes to changes in nutrient cycling and biogeochemistry...
Article
Aim We use cluster analysis to delimit climatically and functionally distinct mammalian faunal clusters. These entities form regional species pools and are relevant to community assembly processes. Similar clusters can be differentiated in the fossil record, offering the potential for use as palaeoenvironmental proxies. Location North America with...
Article
Full-text available
The environmental drivers of species distributions and abundances are at the core of ecological research. However, the effects of these drivers on human abundance are not well-known. Here, we report how net primary productivity, biodiversity, and pathogen stress affect human population density using global ethnographic hunter-gatherer data. Our res...
Article
Full-text available
Despite much interest in the ecology and origins of the extensive grassland ecosystems of the modern world, the biogeographic relationships of savannah palaeobiomes of Africa, India and mainland Eurasia have remained unclear. Here we assemble the most recent data from the Neogene mammal fossil record in order to map the biogeographic development of...

In the version of this Article originally published, each of the five panels in Fig. 5 incorrectly contained a black diagonal line across the plot. This has now been corrected.
Chapter
Full-text available
Ecometrics is a trait-based approach to study ecosystem variability through time. An ecometric value is derived from describing the distribution of functional traits at the community level, which may arise by environmental filtering, extinction, or convergence. An ecometric relationship describes the correspondence between spatially explicit ecomet...
Article
The debate on the Anthropocene has become passionate during the past few years. This is partly because social scientists and humanists have adapted the concept creatively for their own research, as well as criticized the dominant role of natural sciences in defining the Anthropocene. We claim that to achieve a new level of transdisciplinarity it is...
Article
Animals with dietary specializations can be used to link climate to specific ecological drivers of endangerment. Only two mammals, the giant panda (Ailuropoda melanoleuca) in Asia and the greater bamboo lemur (Prolemur simus) in Madagascar, consume the nutritionally poor and mechanically challenging culm or trunk of woody bamboos [1-3]. Even though...
Article
Aim: (1) Survey and organize computational approaches to fossil data analysis into a methodological framework. (2) Highlight the kinds of research questions about evolutionary and environmental change that can be answered by applying computational algorithms to mammal fossil data to better understand past ecosystems and climates. Questions: What mo...
Article
Full-text available
Because body size interacts with many fundamental biological properties of a species, body size evolution can be an essential component of the generation and maintenance of biodiversity. Here we investigate how body size evolution can be linked to the clade-specific diversification dynamics in different geographical regions. We analyse an extensive...
Article
Full-text available
Background: Patterns of change in ecomorphological traits have traditionally been studied using data from the fossil record. Recent advances in molecular phylogenetics created new opportunities for inferring ancestral character states and estimating the modes and rates of trait evolution from phylogenetic hypotheses of extant organisms. However, wi...
Article
Full-text available
At global and regional scales, primary productivity strongly correlates with richness patterns of extant animals across space, suggesting that resource availability and climatic conditions drive patterns of diversity. However, the existence and consistency of such diversity–productivity relationships through geological history is unclear. Here we p...
Article
Full-text available
Ungulate diets may vary following differences in vegetation, and their body size is affected by a complex set of ecological and physiological variables. Here we analyse Middle and Late Pleistocene British and German ungulate palaeocommunities to test whether there are significant correlations of diet and body size of ungulate species with vegetatio...
Article
Full-text available
Ecological communities and their response to environmental gradients are increasingly being described by measures of trait composition at the community level - the trait-based approach. Whether ecological or non-ecological processes influence trait composition between communities has been debated. Understanding the processes that influence trait co...
Article
Full-text available
Ouranopithecus turkae, from the late Miocene of Çorakyerler in Central Anatolia, is considered one of the last known occurrences of great ape in the eastern Mediterranean. The Çorakyerler fauna has previously been correlated with MN 11 to early MN 12 on the basis of biochronology, and its faunal composition has been found to contrast with those fro...
Article
Full-text available
Understanding how ecological communities are organized and how they change through time is critical to predicting the effects of climate change. Recent work documenting the co-occurrence structure of modern communities found that most significant species pairs co-occur less frequently than would be expected by chance. However, little is known about...
Article
Full-text available
There is increasing need to understand the pre-Quaternary warm climates, how climate–vegetation interactions functioned in the past, and how we can use this information for understanding the present. Here we report vegetation modelling results for the Late Miocene (11–7 Ma) to study the mechanisms of vegetation dynamics and the role of different fo...
Article
Full-text available
Ecometric patterning is community-level sorting of functional traits along environmental gradients that arises historically by geographic sorting, trait evolution, and extinction. We developed a stochastic model to explore how ecometric patterns and clade dynamics emerge from microevolutionary processes. Strong selection, high probability of extirp...
Article
Full-text available
Patterns of late Palaeogene mammalian evolution appear to be very different between Eurasia and North America. Around the Eocene–Oligocene (EO) transition global temperatures in the Northern Hemisphere plummet: following this, European mammal faunas undergo a profound extinction event (the Grande Coupure), while in North America they appear to pass...
Article
Full-text available
The fossil record is widely informative about evolution, but fossils are not systematically used to study the evolution of stem-cell-driven renewal. Here, we examined evolution of the continuous growth (hypselodonty) of rodent molar teeth, which is fuelled by the presence of dental stem cells. We studied occurrences of 3,500 North American rodent f...
Article
Modern Asian winter monsoon characterised by the strong northwesterly wind in East Asia and northeasterly wind in South Asia, has a great impact on the surface temperature of the Asian continent. Its outbreak can result in significant cooling of the monsoon region. However, it is still unclear whether such an impact existed and is detectable in the...
Conference Paper
Full-text available
The late Miocene brought about the aridification of most of the Mediterranean environments. Nevertheless, the Vallès-Penedès basin (Catalonia, Spain), escaped this harshening and held humid and forest-adapted faunas until around 9.6 Ma. By combining large datasets of macro- (817 localities and 99 genera) and micromammals (456 localities and 107 gen...
Article
Full-text available
Environmental conditions, dispersal lags, and interactions among species are major factors structuring communities through time and across space. Ecologists have emphasized the importance of biotic interactions in determining local patterns of species association. In contrast, abiotic limits, dispersal limitation, and historical factors have common...
Article
Full-text available
The relative weights of physical forcing and biotic interaction as drivers of evolutionary change have been debated in evolutionary theory. The recent finding that species, genera, clades, and chronofaunas all appear to exhibit a symmetrical pattern of waxing and waning lends support to the view that biotic interactions shape the history of life. Y...
Article
Full-text available
The Anthropocene is recognized (though not yet formally defined) as the time when human impacts are widespread on Earth. While some of the impacts are essential to supporting large human populations and can be sustainable in the long run, others can irretrievably damage the life support systems upon which the global society has come to depend, or s...

Article
Current patterns of biological diversity are influenced by both historical and present-day factors, yet research in ecology and evolution is largely split between paleonto-logical and neontological studies. Responding to recent calls for integration, we provide a conceptual framework that capitalizes on data and methods from both disci-plines to in...
