The functional trait framework provides a powerful corpus of integrated concepts and theories to assess how environmental factors influence ecosystem functioning through community assembly. While common in plant ecology, this approach is under-used in microbial ecology. After an introduction of this framework in the context of microbial ecology and enzymology, we propose an approach 1) to elucidat

Grasslands are among the most threatened terrestrial biomes, and habitat conservation alone will be insufficient to meet biodiversity goals. While restoration of indigenous grasslands is a priority, conflict with economic objectives means that incorporation of alternative habitats is necessary to offset grassland loss. With up to 800,000 km2 of land affected by mining globally, there is an opportu

Nutrients constrain the soil carbon cycle in tropical forests, but we lack knowledge on how these constraints vary within the soil microbial community. Here, we used in situ fertilization in a montane tropical forest and in two lowland tropical forests on contrasting soil types to test the principal hypothesis that there are different nutrient constraints to different groups of microorganisms duri

Reproducible climate reconstructions of the Common Era (1 CE to present) are key to placing industrial-era warming into the context of natural climatic variability. Here we present a community-sourced database of temperature-sensitive proxy records from the PAGES2k initiative. The database gathers 692 records from 648 locations, including all continental regions and major ocean basins. The records

The Indonesian archipelago, Borneo, Sumatra and West New Guinea (Papua), hosts half of the world's known tropical peat swamps, which support a significant proportion of the estimated biodiversity on Earth. However, several species groups that inhabit peat swamp environments remain poorly characterised and their biology, particularly during early life stages, is not well understood. In the present

This article presents a summary of what has been achieved during the last 20 years within the project 'The hawkweeds (Hieracium s.s.) of Sweden' in general, and concerning Hieracium sect. Vulgata in particular, a review of our present understanding of the taxonomy and evolution of this group, as well as some new results and classifications that will be implemented in a forthcoming monographic trea

Morphometric multivariate analysis has been performed based on 23 characters observed on 113 herbariumspecimens from throughout Fennoscandia. This demonstrates that four taxa can be recognised withinErigeron acris L. sensu lato, viz. E. acris L. subsp. acris, E. acris subsp. decoloratus (H. Lindb.) Hiitonen,E. acris subsp. droebachiensis (O. F. Müll.) Arcang. and E. acris subsp. politus (Fr.) H. L

Pottiaceae subfam. Trichostomoideae in Scania, S Sweden – The members of Pottiaceae subfam. Trichostomoideae excluding Weissia spp. in the province of Skåne (Scania), southern-most Sweden, has been revised based on vouchers collected during the ongoing inventory of the bryophyte flora of the province. In addition, all available earlier records have been compiled and are presented for comparison (b

Environmental policy-making increasingly involves ministries beyond environment ministries. In particular, finance ministries are important, since they control the public budget and address environmental issues from a perspective different from environmental actors. The role of finance ministries is especially salient in the European Union's (EU) Emissions Trading System (ETS), which has been subj

Fossil fuel subsidy reform has in recent years been addressed by international economic organizations including the International Monetary Fund (IMF) and the Organisation for Economic Co-operation and Development (OECD). The two organizations have differed significantly in how they define fossil fuel subsidies. The IMF’s definition constitutes a radical break with previous definitions by including

How and why do institutional architectures, and the roles of private institutions therein, differ across separate areas of climate governance? Here, institutional complexity is explained in terms of the problem-structural characteristics of an issue area and the associated demand for, and supply of, private authority. These characteristics can help explain the degree of centrality of intergovernme

Over the past decade, avoiding deforestation has become a central element of the UN Framework Convention on Climate Change (UNFCCC). The focal point of this has been the incentive-based mechanism of REDD+, which stands for Reducing Emissions from Deforestation and forest Degradation. A key notion in REDD+ is to establish incentives for developing countries to reduce their forest-related carbon emi

The bryophyte flora of the canyon Rövarekulan in Skåne, southern-most Sweden, has been thoroughly investigated as reported herein. Including historic records, a total of 200 taxa have been reported, whereof 181 were found in 2023–2024. The most spectacular finding was that of a small population of Didymodon luridus, until recently regarded as extinct in Sweden, growing in a crack in a south-facing

As the politics of climate change shift from the design of international institutions to the pursuit of decarbonisation across multiple sites, researchers are increasingly calling attention to the geography and politics of transitions. We suggest that recent work has so far been limited by its rather incongruous focus on power as a capacity held by individual agents on the basis of the resources w
