The factors that determine species' range limits are of central interest to biologists. One particularly interesting group comprises odonates (dragonflies and damselflies), which show large differences in secondary sexual traits and respond quickly to climatic factors, but often have minor interspecific niche differences, challenging models of niche-based species coexistence. We quantified the env
Anthropogenic elevated atmospheric carbon dioxide (eCO2) increases carbon (C) availability to plants. Whether ecosystems store or release this additional C depends on the balance between net primary production (NPP) and soil respiration, where eCO2-stimulated NPP can be constrained by the provisioning of nutrients by microbial decomposers. Ecosystems gradually become more phosphorus (P)-limited as
Changes in temperature and rainfall associated with altered climatic conditions are likely to significantly alter rates of soil organic matter decomposition. To determine how the combined effects of warming and drought impact the decomposition of fungal necromass, a large and fast-cycling portion of the global soil organic carbon (C) pool, we incubated Hyaloscypha bicolor necromass under both ambi
While fungal necromass is increasingly recognized as a major source of persistent carbon (C) in soils, the relative functional roles of bacteria and fungi in decomposing necromass are not fully resolved, and the processes that select for necromass decomposer communities from the broader soil microbial community are an emerging area of interest. In this study, we characterized the growth of 52 bact
Mycelial residues, also known as fungal necromass, represent a substantial fraction of soil organic matter (SOM) pools in terrestrial ecosystems worldwide. Although microbial decomposers are increasingly recognised as key drivers of fungal necromass carbon stock formation, the diversity and composition of their microbial predators—and the roles these predators play in mediating fungal necromass de
Ectomycorrhizal fungi are critical mediators of nitrogen acquisition in forest ecosystems, exhibiting variation in both host association and metabolic traits that mediate differential responses to forest nitrogen availability. However, how nitrogen acquisition strategies vary among closely related fungal species, how these patterns manifest in conifer-associated ECM fungi, and whether they persist
Elevated ozone (eO3) and atmospheric nitrogen (N) deposition are important climate change components that can affect plant growth and plant-soil-microbe interactions. However, the understanding of how eO3 and its interaction with N deposition affect soil microbially mediated carbon (C) cycling and the fate of soil C stocks is limited. This study aimed to test how eO3 and N deposition affected soil
Sveriges Television kallar sig en TV i allmänhetens tjänst och har en erkänd roll som viktig aktör i den svenska demokratin. I sin roll som public service-företag har SVT en mängd uppgifter att fylla genom sitt programutbud. Public service uppgifter som alla tillsammans skall främja ett demokratiskt samhälle. I takt med att medielandskapet och samhället har förändrats så står SVT:s ar-bete med des
This study aims to develop a theoretical and analytical approach for studying discretion, automated decision-making (ADM) and the consequential public values. This is achieved through our proposed approach, an overview of literature and an empirical test. The context of our empirical test is decisions made about economic support in social work. The research questions are as follows: 1) What are th
The strive to create sustainable societies is often addressed through the lens of social, economic-, or environmental sustainability. However, this division fails to acknowledge existential dimensions of sustainability, i.e., the fundamental concern to sustain a good and meaningful life. This paper expands the notion of Existential Sustainability in relation to socio-material dimensions and built
Health care is moving toward integrated services where care and rehabilitation are provided at home rather than in institutions. This, together with the requirement that care must be person-centered, has proven to be a considerable challenge. Older adults living with complex health conditions such as stroke are vulnerable to change when their responsibility for care and rehabilitation becomes exte
Drought and rainfall events will become more frequent and intense with climate change. At the same time, soil moisture is one of the major factors controlling soil microbial processes such as carbon cycling. When challenged with drought there are two main growth responses microorganisms can use: (1) they can maintain growth rates during drought (i.e., resistance) and (2) they can recover growth ra
Climate change is causing an intensification of soil drying and rewetting events, altering microbial functioning and potentially destabilizing soil organic carbon. After rewetting, changes in microbial community carbon use efficiency (CUE), investment in life history strategies, and fungal to bacterial dominance co-occur. Still, we have yet to generalize what drives these dynamic responses. Here,
BACKGROUND: The endosymbiotic relationship between Wolbachia bacteria and insects has been of interest for many years due to their diverse types of host reproductive phenotypic manipulation and potential role in the host's evolutionary history and population dynamics. Even though infection rates are high in Lepidoptera and specifically in butterflies, and reproductive manipulation is present in th
Traits that affect organismal fitness are often very genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature (after all) “selects” the best genotypes at the expense of those that fall short. Explaining the extensive genetic variation of fitness-related traits is thus a longstanding puzzle in evolutionary biol
Mounting climate-related floods, fires, droughts and storms across the globe raise crucial questions about the role of law in adjudicating rights and obligations. While climate litigation attracts scholarly attention, vulnerable populations often lack the means to use formal laws and courts. We draw on ethnographic interviews conducted in 2022 in the city of Cartagena, Colombia, to study how resid
