Diverse forest landscapes contribute to reaching various forest policy goals. Understanding how the diversity of forests in a landscape is distributed among forest properties and how it is related to biogeographical and ownership factors can be helpful for effective policy implementation. We created a forest characteristics-based typology of non-industrial private forest properties aiming to captu

Soil aggregate stability has been asserted as an indicator of soil quality. Earthworms are essential for the stability of soil aggregates due to their activities, including burrowing and organic matter decomposition. In this study, we focused on how differences in plant litter quality influences earthworm abundance and composition and, subsequently, macroaggregate stability in an agroforestry ecos

There is a growing call for comparative analyses of forest governance to facilitate knowledge exchange for the sustainable management of Nordic forest systems, addressing the needs of societal stakeholders in enhancing both the quality and quantity of forest resources. This study traces the development of nation-wide policy instruments implemented in four Nordic countries; Finland, Sweden, Norway

The evolution of reproductive isolation is a key evolutionary process, but the factors that shape its development in the early stages of speciation require clarification. Here, using a meta-analysis of 34 experimental speciation studies on arthropods, yeast and vertebrates, we show that populations subject to divergent selection evolved stronger reproductive isolation compared with populations tha

The aim of Task 4.1 is to derive emission factors based on bottom-up land surface modelling, using two process-based dynamic global vegetation models (DGVMs), LPJ-GUESS and ORCHIDEE. In recent years, emission factors have been proposed as a useful methodology for estimating greenhouse gas emissions under different land-management strategies. Whilst emission factors are straightforward to implement

The evolutionary dynamics of diurnal Aletis moths (Lepidoptera: Geometridae: Sterrhinae) in the Afrotropics have been obscured by their allopatric distributions, significant inter- and intraspecific variation in adult and caterpillar phenotypes, and involvement in complex mimicry systems. Extensive phenotypic disparity, alongside conserved genital morphology and a lack of suitable material for gen

Following the line of the former Iron Curtain, the European Green Belt links protected areas across 24 countries, and restores key wildlife populations, wetlands and rural livelihoods. Its success proves that rewilding-grounded nature-based solutions can transform war-scarred frontiers into biodiversity-rich, climate-resilient lifelines, and challenges policymakers to replicate such mega-corridors

Rates of molecular, phenotypic, and lineage diversification typically scale negatively with time interval of measurement, raising longstanding questions about time-dependency of evolutionary processes. These patterns and their potential meaning have recently re-entered evolutionary discussions. In this Perspective, we revisit the general challenges in interpreting rate–time relationships. Much app

Godstransporter är en grundläggande förutsättning för samhällsekonomisk utveckling, näringslivets konkurrenskraft och tillgången till varor, men står samtidigt för en betydande andel av Sveriges växthusgasutsläpp. Att minska transporternas klimatpåverkan utan att hämma ekonomisk utveckling är därför en central utmaning. Ökad transporteffektivitet lyfts ofta fram som en nyckelstrategi, men dess potFreight transport is a fundamental prerequisite for socio-economic development, business competitiveness, and the availability of goods, while at the same time accounting for a substantial share of Sweden’s greenhouse gas emissions. Reducing the climate impact of transport without constraining economic development therefore constitutes a central challenge. Improved transport efficiency is often hi

The causal role of pollinators in driving the divergence of plant traits is a fundamental tenet of angiosperm evolution, providing hallmark examples of evolution in response to natural selection. However, it remains unclear how geographic variation in pollinator assemblages relates to the divergence of pollination traits in pollination-generalized plants. We characterized pollinator assemblages th

The need for sustainable agricultural systems, which for example enhance soil organic carbon (SOC) content, has increased the interest for management with reduced tillage. In this study we used a Swedish long-term (20 yrs.) systems experiment, including reduced tillage (harrowing 10 cm) and plowing (moldboard plow 0–20 cm) combined with three levels of nitrogen (N) fertilization. With this setup w

This paper systematically reviews the literature on how to reduce nutrient emissions to the Baltic Sea cost-effectively and considerations for allocating these costs fairly among countries. The literature shows conclusively that the reduction targets of the Baltic Sea Action Plan (BSAP) could be achieved at considerably lower cost, if countries would cooperate to implement the least costly abateme

In this perspective article, we provide recommendations for strengthening the policy framework for protecting the Baltic Sea from agricultural nutrient pollution. The most striking weakness is the lax implementation of prescribed abatement measures, particularly concerning manure management, in most countries. Institutions of the EU should also be leveraged for achieving Baltic Sea Action Plan (BS

It is urgent in science and society to address climate change and other sustainability challenges such as biodiversity loss, deforestation, depletion of marine fish stocks, global ill-health, land degradation, land use change and water scarcity. Sustainability science (SS) is an attempt to bridge the natural and social sciences for seeking creative solutions to these complex challenges. In this ar

Managed honey bees (Apis mellifera L.) are increasingly used worldwide to meet the growing demand for agricultural pollination services and honey production. The spillover of managed honey bees into natural habitats can strongly transform wild plant-pollinator communities, resulting in mixed consequences for plant reproduction. To effectively predict and cope with the impacts of managed honey bees

In this paper we appraise current agricultural subsidy policy in the EU. Several sources of its inefficiency are identified: it is inefficient for supporting farmers’ incomes or guaranteeing food security, and irrational transfer payments decoupled from actual performance that may be negative for environmental protection, social cohesion, etc. Based on a simplified economic model, we prove that th

In the second chapter there is a description of corruption today. First I will provide a definition of corruption. Many definitions exist, but the common criteria in these definitions are abuse of power for private gain to the detriment of public interest. After explaining the theoretical definition I will describe corruption in practice through providing different forms of corruption. Public sect

Non proliferation is an issue of the utmost importance. It might seem that it is an issue more at home in the era of the cold war, however it is very much an issue of the 21th century. Countries like North Korea have not just pursued a policy of acquiring nuclear weapons but succeeded. How to best prevent countries from developing nuclear weapons is a question with no good answer. In the case of N
