Substrate pH has been shown to be important for bryophyte distribution, although bryophytes are believed to obtain more or less all of their nutrients from rain water and deposition of airborn dust. In order to better understand bryophyte-pH relations we investigated pH ranges of bryophytes and bryophyte richness at different pH in southern Sweden. In addition, species turnover and critical pH val
Sexual traits are often the most divergent characters among closely related species, suggesting an important role of sexual traits in speciation. However, to prove this, we need to show that sexual trait differences accumulate before or during the speciation process, rather than being a consequence of it. Here, we contrast patterns of divergence among putative male sex pheromone (pMSP) compos
Sustainable agriculture requires nutrient management options that lead to a profitable crop yield with relatively low nitrogen (N) losses to the environment. We studied whether the addition of contrasting organic amendments together with inorganic fertilizer can promote both requirements simultaneously. In particular we studied how the chemical composition of organic amendments affects the biomass
Males of all species of the parasitic wasp genus Nasonia use (4R,5S)-5-hydroxy-4-decanolide (RS) as component of their sex pheromone while only N. vitripennis (Nv), employs additionally (4R,5R)-5-hydroxy-4-decanolide (RR). Three genes coding for the NAD + -dependent short-chain dehydrogenases/reductases (SDRs) NV10127, NV10128, and NV10129 are linked to the ability of Nv to produce RR. Here we sho
Species with similar resource requirements are commonly assumed to competitively exclude each other, unless they differentiate their ecological niches. Hence, parasitoid wasps that use the same host species need to find some way to avoid competition. The aim of this study was to identify the role of volatile cues from oilseed rape plants and the larval host in niche separation between three coexis
This chapter establishes four evaluative themes that will be employed across this volume to analyze the institutional complexity of policy fields in the climate-energy nexus: coherence, management, legitimacy, and effectiveness. Coherence among institutions is conceptualized along four dimensions: convergence on an overarching core norm for the policy field, balanced coverage and distribution of m
The western Antarctic Peninsula is an extreme low temperature environment that is warming rapidly due to global change. Little is known, however, on the temperature sensitivity of growth of microbial communities in Antarctic soils and in the surrounding oceanic waters. This is the first study that directly compares temperature adaptation of adjacent marine and terrestrial bacteria in a polar envir
Alloimmunization against human platelet antigen (HPA)-1a during pregnancy can cause foetal/neonatal alloimmune thrombocytopenia (FNAIT) and severe bleeding in the foetus or newborn and likely depends on several factors. HPA-1a alloimmunization is associated with DRB3*01:01, which is associated with several DR-DQ haplotypes. However, it is not known to what extent these haplotypes contribute to the
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
Non-technical summaryResilience is a cross-disciplinary concept that is relevant for understanding the sustainability of the social and environmental conditions in which we live. Most research normatively focuses on building or strengthening resilience, despite growing recognition of the importance of breaking the resilience of, and thus transforming, unsustainable social-ecological systems. Undes
We welcome Raymond et al.’s invitation to further discuss the ‘pragmatics’ of relational thinking in sustainability science. We clarify that relational approaches provide distinct theoretical and methodological resources that may be adopted on their own, or used to enrich other approaches, including systems research. We situate Raymond et al.’s characterization of relational thinking in a broader
The human-driven loss of biodiversity has numerous ecological, social, and economic impacts at the local and global levels, threatening important ecological functions and jeopardizing human well-being. In this perspective, we present an overview of how tropical defaunation—defined as the disappearance of fauna as a result of anthropogenic drivers such as hunting and habitat alteration in tropical
Promoting or upscaling governance and business innovations requires an understanding about the conditions and contexts that support a particular innovation. Indeed, context can importantly condition the emergence of new ideas as well as their stabilization and system-level uptake. Ecosystems and the services they provide can be considered this kind of context for innovations because they vary acro
Ecosystems provide multiple services to humans. However, agricultural systems are usually evaluated on their productivity and economic performance, and a systematic and quantitative assessment of the multifunctionality of agroecosystems including environmental services is missing. Using a long-term farming system experiment, we evaluated and compared the agronomic, economic, and ecological perform
Celebrated by some as a ‘new’ mode of governance (Sabel and Zeitlin 2008) and experimentalist architecture (Sabel and Zeitlin 2010), and denigrated by others as a ‘red herring’ (Idema and Keleman 2006), the Open Method of Coordination (OMC) connects with major themes in EU politics and public policy, namely the Europe 2020 strategy for economic growth and competitiveness, the transformation of the
Conifer-feeding bark beetles are important herbivores and decomposers in forest ecosystems. These species complete their life cycle in nutritionally poor substrates and some can kill enormous numbers of trees during population outbreaks. The Eurasian spruce bark beetle (Ips typographus) can destroy >100 million m3 of spruce in a single year. We report a 236.8 Mb I. typographus genome assembly usin
