Human activities in deciduous forests over the past centuries have influenced associated species. To reduce extinction risks and mitigate population declines, there is growing interest in forest conservation and restoration, including initiatives by the European Union (EU). For resulting restoration and conservation practices to succeed, it is essential to know which forest characteristics promote
Pollinators are estimated to benefit the reproduction of three-quarters of global leading crop species and contribute to 3%–8% of the total global food production. Ongoing declines in pollinator populations have raised concerns about repercussions for food security. Thus, there is a need to better understand how agricultural yields depend on pollinator abundance. Here, we established yield–pollina
It is investigated how particles in high-N shells affect the moment of inertia, {A figure is presented}(2), and the quadrupole moment, Q0, of superdeformed high-spin states. The different behaviour of {A figure is presented}(2) versus the rotational frequency observed for superdeformed states in 152Dy and 149Gd is explained in terms of different occupations of a few high-N orbits. Predictions for
The yrast states of 160Yb are calculated using the cranked HFB model with particle-number projection and assuming diabatic bands. The energy of each state is minimized with respect to the proton and neutron pairing gap parameters and the deformation parameters ε and γ. The deformation of the ground band is found to increase with increasing spin, i.e. ε gets larger. Simultaneously γ gets slightly n
Calculations with the cranking-plus-Strutinsky formalism indicate that some part of the yrast line in almost all the nuclei of the A ∼ 40-80 region may be of non-collective type, corresponding to rotation around a symmetry axis. A numerical study of many such single-particle spectra shows that even at very high spins there is a non-negligible probability for the occurrence of isomers. This conclus
Using the EU as case study, we simulate the impact of border carbon adjustments on agri-food markets. While border carbon adjustments alleviate adverse carbon price impacts on EU agricultural competitiveness and emission leakage, our simulation results also reveal that (i) border carbon adjustments may diminish domestic mitigation efforts, thereby partly offsetting benefits from reduced emission l
Timber buildings present unique fire safety challenges compared to non-combustible constructions. Fire damage in timber structures includes smoke, heat-related impacts and firefighting water. Effective fire mitigation strategies, such as smoke detection systems, automatic suppression systems, and compartmentation, can be crucial for enabling timely interventions and minimizing damages. Post-fire r
Bees are pollinators of both wild and crop plants with significant ecological and economic value. However, recent studies report declines in their populations, particularly in agricultural landscapes. Compared to conventional farming, organic agricultural management is considered less harmful to biodiversity. Despite this, studies addressing wild bees in organic systems remain limited. In this stu
Water resources are under increasing pressure from population growth, climate change, and intensified human activity. Effective water management requires a clear understanding of both surface and subsurface hydrological systems, yet traditional monitoring methods often fall short in spatial and temporal coverage. Interferometric Synthetic Aperture Radar (InSAR), a satellite-based remote sensing te
The aim of this thesis is to investigate the effectiveness of using specific alarms for each hazardversus the effectiveness of using a single alarm for all hazards in multi-hazard facilities. Theresearch was conducted by disseminating online questionnaires containing audio files of differentalarms to occupants of multi-hazards facilities and conducting interviews with safety expertsworking at mult
Effective governance and management of ecosystem functions to promote human well-being and social equity require a clear understanding of supply and demand dynamics. While this is widely acknowledged in assessments of ecosystem services, it remains largely neglected for ecosystem disservices, despite many ecosystem functions generating both services (benefits) and disservices (costs) depending on
Huntington's disease (HD) is a fatal neurodegenerative disorder characterized by progressive motor, cognitive, and psychiatric symptoms. Research efforts to understand and treat the disease have historically focused on neuronal pathology, but growing evidence underscores the critical role of oligodendrocytes in its pathogenesis. This review synthesizes recent findings on oligodendroglial dysfuncti
Circularity metrics simplify complex systems, and trade-offs between simplicity, scope, and usability introduce unavoidable limitations. We revisit the Ellen MacArthur Foundation’s Material Circularity Indicator (MCI) to identify opportunities for a more accurate, comprehensive, reliable measure of circularity. Although widely used and highly regarded, the MCI exhibits limitations and methodologic
The Kant Walks, 2003–2004 - Photographic seriesJoachim Koester’s series The Kant Walks explores the physical paths once walked by philosopher Immanuel Kant in 18th-century Königsberg (now Kaliningrad) Bydocumenting these routes, Koester uncovers physical layers of history, abandoned settlements, and forgotten places His photographs – often depicting empty,decaying urban landscapes – pose the quest
Current advancements in molecular techniques for identifying multiple species from bulked soil samples have expanded our capacity for large-scale soil biodiversity assessments. However, these methods often lack validation and contextualization. Recent cross-European studies based on environmental DNA (eDNA) have reported unexpectedly high biodiversity in intensively managed agricultural soils comp
Anthropogenic land-use and climate change pose novel selection pressures on bees, yet their evolutionary responses in terms of morphological or physiological adaptations remain unclear. While adaptive responses are expected, these may be constrained by gene flow when changes in selection pressures are spatially heterogeneous. The buff-tailed bumblebee (Bombus terrestris) is a widespread species th
The level structure of 102Rh has been investigated using the EUROGAM Phase2 array. Bands observed up to high spins are discussed in terms of band terminations. 102Rh is the first doubly odd nucleus below Z = 50 in which band terminations are established.
Magnetic Weyl semimetals have emerged as a fertile ground for exploring quantum phases of matter and quasiparticles. The latter includes unconventional fermions with larger Chern numbers than those of conventional Weyl fermions and topologically nontrivial band structures in bosonic excitations. They hold potential for further experimental exploration of emergent quantum matter, magnon-polarons, w
Plant functional traits are fundamental to ecosystem dynamics and Earth system processes, but their global characterization is limited by available field surveys and trait measurements. Recent expansions in biodiversity data aggregation—including vegetation surveys, citizen science observations, and trait measurements—offer new opportunities to overcome these constraints. Here we demonstrate that
