We measured πΣ invariant mass spectra below and above the K̄N mass threshold in the K-d → NπΣ reaction in order to study the K̄N interaction and the Λ(1405) resonance. This reaction can be described by the two-step process: (i) K-N1 → K̄N followed by (ii) K̄N2 → πΣ, where N1 and N2 are nucleons bound in the deuteron. We deduced the S -wave scattering amplitude of K̄N → K̄N as well as K̄N → πΣ in I

Climate limits distribution of species and shows considerable regional variability. However, studies relating climate variation to species population growth rates in different climatic zones while accounting for species' ecological traits are scarce. We assessed species population responses to the main climatic constraints at a continental scale by studying how precipitation and temperature at dif

Gut microbial communities can facilitate traits that are essential for invasive species survival in novel environments. Despite the global plethora of invasive social insect species, the role of the gut microbiome in colonisation success under novel dietary and environmental conditions is little known. The introduction of the European buff-tailed bumblebee, Bombus terrestris, to the island of Tasm

Improved understanding of the mechanisms driving heterotrophic CO2 emissions after rewetting of a dry soil may improve projections of future soil carbon fate. While drying and rewetting (DRW) under laboratory conditions have demonstrated that heterotrophic CO2 emissions depend on DRW features and soil and environmental conditions, these laboratory insights have not been validated in field conditio

The International Monetary Fund (IMF) is a highly influential financial international organization that will be vital for the success of the Sustainable Development Goals (SDGs). While the IMF has been criticized by civil society actors for its negative impact on sustainable development, it is now focusing on supporting the SDGs. This support is particularly relevant when it comes to ensuring the

This is the first comprehensive checklist and conservation assessment of the bee (Hymenoptera: Apoidea) fauna of the State of Vermont. This checklist of 351 species (plus 1 morphospecies) is based on 79,206 open-access data records available from the Global Biodiversity Information Facility (GBIF), nearly all (98%) of which were identified by an author or trusted collaborator, including 100% of th

Climate warming, nutrient loading, and pesticide pollution are major anthropogenic stressors affecting community dynamics and trophic interactions in aquatic ecosystems. However, the complex interplay among these stressors remains poorly understood as most studies focus on a single stressor and overlook the effects of temporal variations. To address this knowledge gap, we first conducted a long-te

Estimating and monitoring migratory bird populations involves significant challenges, even in the most well-studied and easily-counted species, and can be further complicated by long-held but unverified assumptions and by shifting distributions in changing flyway conditions. We illustrate these challenges using Bar-tailed Godwits Limosa lapponica on the East Atlantic Flyway. The subspecies L. l. l

Despite international commitments to phase out fossil fuel subsidies, OECD countries exhibit substantial variation in subsidy levels. This study examines how governing party preferences and institutional context jointly shape subsidy policy across 28 OECD countries from 2010 to 2022. Integrating party manifesto data with fossil fuel subsidy levels in cabinet-year panels, the analysis reveals condi

A forthcoming taxonomic treatment of the genus Verbascum in Greece in the frame of The Flora of Greece Project necessitates the description of one species and two subspecies as new to science, the upgrading to subspecies rank of two taxa formerly recognized as varieties, as well as the formation of two new combinations. Verbascum bolbes from the regional unit Thessaloniki is here described as a ne

Although the moth fauna of South Sweden is relatively well known, information about the habitat preferences of species is scarce. To fill this gap and document the relative richness and conservation value of different habitats, 32,683 moth were caught in light traps at >200 sites in Central Skåne (prov. Scania). The relative frequency of species, major taxonomic groups and species with different f

Nineteen new, presumably apomictic species of Hieracium sect. Tridentata, namely Hieracium anisodontum, H. bicoloriceps, H. disparifolium, H. ditrichum, H. erectifolium, H. ferox, H. lapsanae, H. luteoviride, H. megaplicatum, H. multifolium, H. paer-haraldii, H. perpendiculum, H. phaeochlorum, H. prasiniceps, H. semirigidum, H. serriolum, H. spinophytoides, H. svensonii, H. xantholineatum, and one

Habitat loss and nutrient enrichment are major drivers of plant species declines. However, local extinction risks vary widely and are shaped by life-history trait syndromes. Genomic life-history traits, which are simple, stable and widely available, offer a promising yet underexplored approach to improving extinction risk assessments and informing conservation efforts. Using a spatial comparison a

Increasing frequency and intensity of droughts threaten grassland ecosystems. Semi-natural grasslands vary in age from ancient to younger sites established on former arable land. While species richness and composition are known to affect drought resilience, little is known about how grassland age shapes drought responses through eco-evolutionary processes at the plant population level. We explored

This article examines how intensive care staff navigated the emotional and temporal complexities of the COVID-19 pandemic, drawing on qualitative data from two Swedish ICUs. Rather than treating emotional responses as secondary reactions to crisis, the analysis shows that emotions were deeply embedded in professional feeling rules, organizational hierarchies, and the poly-temporal unfolding of the
